Martinez returned from maternity leave on July 23, 1986. Fifty-eight personnel-exposure samples were collected In July. Below is a list of sampling by contaminant: f" ` Formaldehyde TWA STEL 9- Methanol 8- Noise 8-- Total Duet 5- Benzene 12 - Mica 22 Asbestos 21 Antimony -1 Cadmium 4- Ethylene Oxide 4 - In addition to the samples listed above, twenty-eight TWA noise samples were collected for L. Trejo in conjunction with noise reduction projects. Validation of alternative HCHO-exposure monitoring techniques will soon begin. The dynacallbrator (for preparing dynamic HCHO blends In air) is now fully operational. The CEA-5SS formaldehyde analyzer (for verifying the output of the dynacallbrator) was also made operational, but this Instrument was found to have problems with baseline stability and linearity. The output of the dynacallbrator will be verified using manual wet-chemical methods, such as the pararosaniline procedure (upon which the CEA-555 is based) and the chromotropic acid procedure. One formaldehyde permeation tube was received this month, and initial work has begun on dynacallbrator output verification. In support of the Formaldehyde Reduction Task Force, area samples for HCHO were taken in the Ceicon* Units using the Miran and Lion 'k Formaidemeters as well as an acetyl-acetone procedure. Results indicate a significant trioxane Interference In samples collected in TO-2. Sampling support will continue as needed. Two proposals for enhancing the BLISS system have been ordered from Baytek Engineering. These software enhancements should be complete near the end of August. A control chart package for the same software should be complete sometime in September, 1986. Some of the new features of BLISS will automate some Quality Assurance functions and others will be used to aid the Laboratory SPC process. 009973 CDB-382-86 Page 2 August 11, 1986 A series of core tests on the 4-HAP oxime mother liquor were run at CORE Laboratories in Dallas In early July. The tests were designed to simulate injection of fluids containing 4-HAP oxime mother liquor at down-hole conditions. Preliminary results show that oxime mother liquor with normal levels of reactive materials (primarily hydroxylamine) are Injectable. One test on undiluted oxime mother liquor with about five times the normal level of hydroxylamlne showed that there may be the possibility of two-phase flow down-hole at very high levels of hydroxylamlne. Normally, the oxime mother liquor will be diluted by the polyol waste stream at an 8:3 polyol to oxime mother liquor ratio. J. E. Ruaaell attended a seminar on the Validation of Computer Systems for Pharmaceutical Research and Development held In New Jersey. This was a good first view of the FDA's Involvement and thoughts about computers and their association with data recording. It appears that the FDA Is significantly lacking in modern equipment and Is In the very early stages of learning to deal with computer-based data management systems. Hubert H. "Hub" Thigpen was promoted to Associate Chemist effective August t, 1986. WEST LABORATORY Representatives from the Laboratory and Quality Assurance visited the CAF facility in Wayne, NJ to review the testing and release procedures used for the GAF products. The GAP Wayne Lab will not be able to test products after September 30, Bishop is to assume responsibility for the quality control and release of the products. A round-robin between the Bishop Lab and CAF Is currently underway to resolve any testing discrepancies. Methods for black speck determination by the Image Analyzer have been developed and parameters defined (black speck sizes) for two Celanex keycap products, Apple brown and an H-P grey. Several extended analytical runs using eight disks for evaluations have been conducted, but st'4ge problems have hampered complete evaluation of the methods. Based on the preliminary runs, it appears that the number of black specks detected by the Image Analyzer will be two to three times greater than detected by visual count. The Increase is because the Image Analyzer consistently "sees" a speck, whereas specks are not always seen by the human eye during a visual Inspection. Final comparisons of the visual method and the Image analyzer method will be completed once the stage problems are resolved. The West Laboratory Quality Manual has been revised to reflect changes highlighted by the recent BS1 audit. Necessary equipment for the proper tool and gauge calibrations have been ordered and are expected to be In place by the follow-up BSI audit in September. 009974 GDB-382-86 r Page 3 August 11, 1986 The Initial testing of the physical testing round robin samples have been completed. Samples molded at Summit, SPF and Bishop were tested to determine any discrepancies in molding and physical testing procedures. Samples are also being tested at the other locations. A report will be Issued with Bishop results. A meeting la scheduled for late August to review all the data and determine If additional testing is necessary. r* Evaluation of the "anti-static decay" test method at Bishop has been delayed. It appears the test method la extremely sensitive to variations In molding conditions and sample handling, resulting in poor reproducibility. Both Summit and Bishop are working to resolve this problem. The flowcharting and the "Cause and Effect" diagram for the Halt Index process have been completed. The use of these tools for Improving the actual analytical method has been Implemented In the Laboratory. Data collection and control charting under the new guidelines has begun. Review of the effectiveness of the guidelines will be conducted In the future as an on-going part of the SPC program. The izod method haa been selected as the next analytical procedure to undergo the SPC evaluation process. PROCESS ANALYZER CROUP The Installation of analyzers on the Spill Containment Project is proceeding smoothly and on schedule. Seven out of eight of the TOD and pH analyzer systems have been Installed. All but one of the TOD analyzers are operating well. Work Is underway to resolve reproducibility problems on one of the TOD analyzers. Training on the new Ionics H-85 TOD analyzers Is complete. Analyzer mechanics and engineers received two days of hands on training conducted by Ionics. * - An Ionics H-85 TOD analyzer Is being evaluated as a possible replacement for COD analyzers on the front ditch. Thus far, reproducibility haa been unacceptable and several attempts to improve it have been unsuccessful. Help from the vendor Is being sought to resolve these problems.. - The SH-2 Komllne-Sanderson and the Quench tank vent oxygen analyzers continue to run well. The occasional signal spiking experienced with the Quench tank analyzer has been resolved by Installing the aspirator Inside the oven. A recorder has been installed to observe the reliability of the analysis. Barring any problems these analyzers should be ready for automatic safety control by 9/1/86. r 009975 GOB-382-86 Page 4 August 11, 1986 - The MH-2 flake conveying system will utilise an oxygen analyzer recovered from the old paraform unit* This will reduce both Installation time and costs without sacrificing analysis quality. Installation Is 502 complete. Use of other Idle 0. analyzers for the Celcon Process Safety Improvement Project Is being considered as a cost saving measure. - The HU-2 Rector Feed GC was down all month. We are still trying to resolve pump problems. We are also awaiting the completion of modifications to the Tltrator sample system cyclone. Construction should be complete by August 15, 1986. Work is progressing on the SH-1 analyzer house. A delivery of September IS, 1986 is anticipated. The Installation of a conductivity analyzer on the MS cooling tower blowdown is complete. Analyzer startup has been delayed due to a bad measurement cell. This will be replaced under warranty. Celcon #2 cooling tower pH meter and cell are installed -- waiting on electrical. - T-243 OH Nuclear density meter has been, operating satisfactorily. A new calibration procedure has been established for the transmitter and seems to have solved some of the problems. - In response to a deficiency noted by BSI, a calibration and maintenance log has been established for the analyzers in the Celcon area. The log will be kept In the unit and should be In "full use" by August 4. - The Analyzer Group's SPC Team Is now concentrating primarily on analyzers in the Celcon/Trioxane area of the Plant. Several charts are currently being maintained in this area and the group has Identified several other charts that ate needed. These charts are beginning to pay benefits by improving accuracy, reducing the number of calibrations, and ldentl|ylng inferior and superior components. The work on the use of Megabore capillary columns in Process GCs and unit lab GCs is continuing. The first capillary column Installed in a Process analyzer (VI505- MH-2 TO Feed GC) continues to pay dividends with Improved precision, reduced analysis time, excellent column stability and low maintenance costs. Results also look promising for use In unit lab GCs for the analyses of methanol In formaldehyde and ethanol in methanol. CELANESE ENGINEERING RESINS Bishop, Texas TO: FROM: Mr. D. W. Steele G.

The output of the dynacallbrator was verified by collecting 6-8 samples at four different formaldehyde levels and analyzing the samples using the chronotropic acid procedure. One level mas also cross-checked tpqlng the pararosanlllne procedure. All analyses mere within 101 of the calculated output. Therefore, the calculated output was used as the true output for all subsequent work. Work on determining the accuracy and recovery efficiency of the method Is nearly complete. Scrubbing solutions of 20 mL water, 25 mL water, and 20 mL of 51 ammonium acetate were examined. All had approximately the same scrubbing efficiency, so 20 mL of water will be used as the collection media. The average recovery efficiency Is approximately 851, and the accuracy Is well within Celsnese guidelines. Area H2S monitoring was conducted at the BOO reactor to determine approximate concentrations in the vent line. Technical support (area and personnel monitoring) was provided for the recent asbestos spill in Filled Resins. Seventy-seven personnel-exposure samples were collected in August. Below Is a list of sampling by contaminant: Asbestos Benzene Ethylene oxide Formaldehyde Methanol Noise OSHA Total dust TWA STEL 28 6 2 6 4 6 18 4 3 The two proposals for enhancing the BLISS system ordered In Kay and July are 90Z complete at Baytek Engineering. One feature (running a data search from a command file) has already been received. The other enhancements can not be installed until we receive the software update from Hewlett-Packard for the operating system and Che LAS (Laboratory Automation System). Hewlett-Packard should provide those updates once we have a purchase order issued and can schedule an Installation. A control chart package to Interface the BLISS system will be available with the next upgrade, which Celanese will receive along with our customized modifications. The custom modifications plus the other improvements will continue to make the data In the data base more accessible and provide the capability to generate control charts quickly. GDB-386-86 Page 2 September 8, 1986 The Traffic Shipping List was modified to Include the BLISS unit, code, and quality notice format file name with each shipment entry. This Is a tremendous help to the Laboratory technicians and the Quality Assurance clerk In keeping the data going In the right places* Business Systems personnel accomplished the changes to the Traffic Shipping list and created a new program to allow QA to enter the data required for the new fields. & A series of pressure-volume-temperature tests on the 4-HAP oxime mother liquor mixed with polyol effluent and ferric ammonium sulfate were run at CORE Laboratories in Dallas In August. The tests were designed to simulate the gas evolution that would be experienced downhole if the oxime mother liquor were diluted with polyol and Injected. Past tests had shown the possibility of two phases existing at downhole conditions. Preliminary results Indicate that the hydroxylammonium sulfate concent of the oxime mother liquor will have to be monitored to insure that excessive gas generation will not take place after deep well Injection. An approximate one-to-one gas-to-llquld volume ratio Is the limit of gas solubility at about 1800 psl. The results of the core testing and pressure testing will be documented after this last report is received from CORE Labs. J. E. Russell visited the Clear Lake plant to learn about their Laboratory-SPC program and to learn about their approach on plant-wide data base systems. Their Laboratory SPC program has been In existence much longer than the East Lab program. All of their gas chromatograph methods are now monitored by SPC and some Improvement in variability has been achieved on many of them. Almost all other Instrument analytical methods are also monitored by SPC. Rone of the wet chemical methods except for color determination have been included In the SPC effort so far. Soil samples from all of the Solar Ponds (Including the active ponds) were sent to CORE Laboratories for specific organic and Inorganic component analysis. Samples were also sent to CCTC for formaldehyde analysis by Polarograph. These analyses were a part of the data required for the TWC cappling application. k The benzene and MEK concentrations ranged from >1-12 ppm. No carbon disulfide was detected and all extracts except 1 contained >15 ppm formaldehyde. 15 ppm formaldehyde was the minimum detectable limit for the extracted samples because of a dilution factor of 5. A report will be Issued detailing all organic and inorganic concentrations. WEST LABORATORY Methods have been developed and parameters (black speck sizes) defined for the brown and gray Celanex keycap products. Analytical runs using eight to ten disks for evaluations are being conducted to determine the analytical variance between runs and how these compare with the actual number of specks which are present. 009980 GDB-386-86 Page 3 September 8, 1986 A flowchart for the Izod method ''process' has been completed. This Is the second process to be evaluated by the West Laboratory SPC Team. The first process, the melt Index method, la being monitored to determine Che effects of the implementation of SPC techniques. The Laboratory is supporting Nylon operations personnel In Identifying the source of wfjfer in the Dowtherm used to heat the nylon reactor coll. The source of the water may be a reactor leak or a condeaser leak on the vent of the Dowtherm system. The reactor coil leak hypothesis is supported by the presence of ammonia or an amine (possible decomposition products of the nylon salt). However, no adipic add was observed in the system. If a coll leak did not exist, the only other currently known source of water would be the condenser cooling water. Both of these possible leak sources are being monitored to determine which is the problem. G. D. Boyd and T. A. Jasek attended a demonstration of a robotic automation system presented by Zyoark, Inc., In San Antonio on August 27, 1986. The system consisted of the robotic arm and associated computer control system. The focus of the demonstration was the associated modules, each with a defined purpose, which allowed for easy set up and start up. A. E. Retherford and N. A. Platen attended a meeting In Summit to further discuss the incorporation of GAP sample testing and finished lot releasing at Bishop. B. D. Fink, J. Morrow and D. Samms, were also In attendance. Procedures were developed to begin receiving GAP samples from the outside compounders at Bishop for testing. Samples have begun to arrive and testing Is la progress. The samples are also being tested In the Hayne, N. J. laboratory. Initially, analytical results between the two labs are good. September 9, 1986 appears Co be a realistic target date for fully implementing the testing at Bishop. Vork continues on the West Laboratory Quality Manual. Temperature and tool and gauge calibrations are la progress on numerous equipment la the Laboratory and In production. With the exception of vacuum and pressure gauges, calibration is expected to be complete by the September BSI follfcw-up audit. Equipment is on order for the calibration of pressure and vacuum gauges. Calibration will be completed upon arrival, A meeting to discuss the Initial results of the physical testing roundrobin results was held in late August. Representatives, from Florence, Summit, and Bishop attended. The conclusions and further action Items will be published by 0. Garcia. A second round of testing Is expected to conclude In December. Vork continues on the evaluation of the "anti-stat decay' method for AS270 products. Bishop is still having problems resolving the variations seen In the same sample on repeat moldings. A 2-inch disk Insert has beea ordered for the 'HDD' mold. It Is hoped that molding on the Cincinnati machine will decrease some of the variability and will more closely resemble conditions used by Summit. The insert Is expected to arrive in 4-6 weeks. 009981 PROCESS ANALYZER GROUP The MH-2 flake conveying system oxygen analyzer installation Is 90Z complete. Start-up should be complete by 9/15/86. The HU-2 quench tank vent oxygen analyzer sample system will be revised to Include a steam jet aspirator and a liquid knock-out system. Installation Is approximately 25X complete. Design work has resumed on the Installation of the remaining four oxygen analyzers In Celcoo. Pour surplus Taylor analyzers will be used, saving approximately $30K-$50M and reducing Installation time. The HH-2 Reactor Feed GC remains down due to sample pump reliability problems. ModfjElcatlons to the MH-2 Titrator sample system cyclone have been completed. The modifications to the cyclone discharge appear to be an effective solution to the plugging problems encountered before. Titrator method optimization is underway to Improve analysis repeatability. The MH-2 TO feed (V-1505) GC continues to run-well. The MOMA and DIMOMA analysis is being used in a closed loop to control MEAL addition In the reactor. Work Is progressing on the SH-1 analyzer house. A delivery of about 9/15/86 Is anticipated. Dohrman personnel gave a short training course on their TOC analyzer to the analyzer mechanics. The course covered analyzer operation and general maintenance. Celcon #2 cooling tower pH Installation is complete and Is working well. The density gage on T243-OH is complete and all needed data has been collected and quanltated. The documentation package will be Issued in September. A redundant pH analyzer has been added to the Front Ditch to back up the existing transmitter. This should Increase the confidence level on a pH excursion to the Pront Ditch. The installation of TDD and pH analyzers on the Spill Containment is nearing completion. All analyzers have been installed and are operating "on process" with signals going to the computer. Final optimization and checkout is uadervay. . The evaluation of TOD as a replacement for the Front Ditch COD analyzers Is on hold pending shipment of a new M-85 TOD (loaner) analyzer from Ionics. An inspection of the Plant was conducted on August 5 by the State Bureau of Radiation Control. The inspection consisted of selective examinations of procedures and records, Interviews, radiation surveys and a tour of various Installations. The Inspection went well. One technical violation was noted: "Current copy of the Texas Regulation for Control of Radiation was not available." This Is being corrected. 009982 .V f STATISTICS Z OVERTIME Z ABSENTEEISM EAST LAB 4.7 6.3 WEST LAB 8.1 0.2 PROCESS ANALYZER GROUP 3.4 1.9 GDB/erg ( ** ( 009983 ccnszentv. vaa * CELANESE ENGINEERING RESINS Blahop, Texas TO: FROM: Hr.

Luis Benavides reported to the East Lab on March 31 and Is presently training in the .chemical section. His projected training completion date is Hay 2, 1986. * - Pam Vagner reported to the West Lab on March 31, 1986. Fifty-nine personnel samples were collected in March. Below la a list of sampling by contaminant: Antimony Asbestos Formaldehyde Noise Total Dust TWA STEL -l 31 19 29 6 In addition to the samples listed above, 4 Assay Technology badge samples (formaldehyde) were collected for the side-by-side comparison study, 19 area noise samples were collected for Leo Trejo (noise reduction projects), and 13 area formaldehyde samples were collected to determine background formaldehyde levels in Kingsville, Bishop, and Corpus Christi. Revision A.83 of the RTE-A operating system for the lab HP-1000 was installed on March 19, 1986. Only two hours down time were required to Install the new software because the majority of the work was accomplished at Hewlett-Packard'8 Corpus Chrlsti office. A newer version of the LAS (GC software) and BLISS were installed at the same time. One training session for non-Lab personnel on the use of the BLIS$ search routine was held March 20. This search routine allows sophisticated access to the analytical results in the Lab data base. More training sessions will be held as interest demands. The initial meeting of the Laboratory SPC team was held on March 25, 1986. Team members include Leanne Harvey, Team Leader; Jim Russell, Facilitator; Felix Soliz, Lab Supervisor; Clnda Alvarado, Rey Garcia, Don Skrovan, Jim Vargas, and Steve Vogt. Rodney Pope is also assigned to this team and will join us upon his transfer to the East Laboratory in May. Flow-through core-testing of the simulated APAP unit waste streams was completed in March. As suspected, the hydroxlamlne proved to be Incompatible with the Bishop and Bay City well formations. Hydroxylamlne reacts at room temperature in the core, causing much gas formation. The testing will be documented in April. 009996 Development of the 1,4-dloxolane process Is nearing completion. Total organic carbon analyses of the waste water stream Indicate that there ere unknowns present which we do not see by our gas chromatography (GC) analyses. These "extra" by-products reduce the yield by 0.5 - 1.0Z. Current work is focused on determining whether "inerts" have built up in the reaction mixture which may require some blow-down and efficiency loss. The Tech Center will do some corrosion testing to help select a suitable material of construction for the reactor and reboller. This will complete the development effort. Our current best estimate of process yield to dloxolane Is 95Z based on formaldehyde fed and 96Z based on ethylene glycol fed. WEST LABORATORY The Tech Center has completed analyzing the various distillation samples of return methanol from SH-1 using gas chromatography/mass spectroscopy (GC/MS). These analyses did not Identify any potential compounds which would cause yellowing of Celcon (when reacted with Irganox). Since the GC/MS analyses concentrated only on the major components, concentration and separation of the minor components Is underway using liquid chromatography. Method development ( utilizing the Image Analyzer) for black specks In Celanex keytop products Is In progress. Speck sizing and differentiation is underway. Analysis for silicone oil In four complaint lots from Polyplastics has been completed. Three of the four lots were found to contain less than 18 wtZ silicone oil (specification 20 +_ 2 wtZ). The samples were analyzed using a gravimetric method. Additionally, one sample was analyzed by the method used by Polyplastics. The Bishop analysis was confirmed by the Polyplsstlc analytical method. An EMS Advisory Council was established to provide guidance and maintain smooth operation of the EMS Crew. The membership was established and some preliminary action items were assigned. The first meeting Is tentatively scheduled for May. David Clapper (Senior Lab Technician) and Toyo Kawamura (Warehouse Foreman) provided two 40-hour ECA courses for the new members of the EMS Crew. Thank you, David and Toyol PROCESS ANALYZER GROUP All pH meters and sample loss flow switches for the Spill Control project are In Plant. Initial TOD analyzer checkout and factory training has been rescheduled for April 23 and 24. The first two TOD analyzers are now scheduled to ship to Bishop during the last week of April* Sample system optimization continues. 009997 L The Acetate reactor water analyzer la on-line and showing acceptable correlation with Karl Fisher water analysis. Unit lab sampling has been reduced to once every two hours. Problems were encountered with the MO-IV absorber vent analyzer. Z HCHO has been low and aometlmes below the detectable limit of the analyzer. Some problems In the sample system have been Identified. Work Is continuing to resolve these problems and Identify others. CO analyzers were Installed In the HS control room AC duct and the tank car cleaning ifafck breathing air. These are both operating well. The engineering 'package for the T-243 OH density meter Is complete and the analyzer should be Installed In April. The SH-2 Komline-Sanderson oxygen analyzer has been taken off-line until sample system modifications are complete. The SH-2 Quench/Grinder Vent oxygen analyzer's purge was incorrectly connected to 1 pal nitrogen, which was Inadequate for purge requirements. He are awaiting the connection of approximately 40 psi nitrogen. The MH-2 TO Feed GC has been up and running most of the month, and has been turned over to the unit. The Honda feed GC is in the final stages of commissioning, and calibration methods are being optimized. We anticipate completion by mid-April. The tltrator was started up for the analysis of low levels of free TEA before and after the HH system. We are currently optimizing the analysis parameters. Plugging problems have been encountered with the Quench tank sample stream to the tltrator. Engineering Is making piping modifications to correct this. A Unlloc oxygen analyzer, salvaged from Paraform, will be Installed on the Flake Compaction/Transfer system.

These costa are not calculated by the Accounting Department methods and do not represent current allocated Laboratory charges. The following Is a summary of what these costs represent and how they are calculated: 1. Costt are for analytical services provided by SNE personnel only. (Routine Analytical) 2. Reporting Is on a calendar month basis. 3. Charges are based on average analyst time to complete an analysis multiplied by an hourly analyst rate. 4. Analyst rates are determined from the annual Laboratory budgets and the number of analyst hours available. 5. Only budget Items supporting the routine analytical function are included In the rates. Detailed analyltlcal cost reports will eventually be' provided for each product line. These reports will differ depending whether .they are generated by LDMS or BLISS but will contain essentially the same information. LDMS generated reports for Celcon are attached for general distribution this month as examples. The costs are incorrect in the examples but can be multiplied by 2 to obtain approximate values. Correct detailed reports will be distributed to all product lines serviced by LDMS In May. Reports from the BLISS system should be available in June following corrections to the system library program. Detailed reports from both systems will be sent only to the product line superintendents unless otherwise requested. A monthly 'LABORATORY ANALYTICAL COST SUMMARY' should also be completed in June and will be widely distributed. An Incomplete summary Is Included In this report. 009999
