4 TENNECOTER-OFFICE MEMO CHEMICALS, INC. To Distribution List At from Miringoff Burlington object Meeting Review of Progress of VCM Program August 28, 1975 at Burlington Attendees: W.C. Champion L, Iszak Dr. P.A. Lobo W. Miringoff G.I. Rozand P.R. Scarito P. Scheiner E.V. Schenke C.G. Thompson T.T. Zuhl date September 2, 1975 Fantercopy to r.f, J.W. Poarch E, Schwartz J.T. Sweeney P.L. Wilson w'f'ile Clean Air Rooms - Priority I (E.V. Schenke) The Burlington design will be based on a maximum of five-people occupancy. The design will try to incorporate the control panels as one wall of the rooms. In addition to the four panel board clean air rooms, a clean air room will be provided for the copolymer charging scale and for the plastisol stripping area. The preliminary designs will be reviewed with Manufacturing in mid-September with a final design ready by the end of September. The location for the air intake at Burlington will be selected from data of air sampling tests performed by W.C, Champion's group at the boiler house, the west end of the bulk bins, the south end of the warehouse roof and the plastisol dryers air intake. The Flemington air intake will be the northwest corner of the reactor building roof unless the VCM data to be taken by W.C. Champion shows this to be an un desirable location. The Flemington clean air room CAR will be submitted for approval in September. Blend Tanks - Priority I (P.Scheiner ) All of the Burlington Suspension Plant blend tanks have been sealed. The vent stacks currently cause a VCM problem in the reactor building. The stacks will be extended to a high elevation via a common stack and so designed as to be able to duct these exhausts into a future carbon adsorption system. Other stacks and pipeline exhausts will be looked at in order to consolidate the overall design. The Flemington blend tanks will be sealed when the design used at Burlington is proven to be effective. The CAR for foam control and sealing the plastisol blend tank agitator (#6) is in for approval at Saddle Brook. COLORITE 011202 Page 2 Reactor VCM Removal (J.W. Poareh) Based on encouraging test results at VCM removal from reactors at Burling ton via 300-gallon hot water injection and vacuum, a three-to-four-day full out Suspension Plant program will be implemented next week. This program should result in reduced general VCM levels in the plant en vironment and will be monitored closely via the Bendix monitoring system, reactor vapor space sampling and overall performance evaluation by Process Engineering. This technique will also be extended via several special batches using 180F hot water and the use of two parallel compressors to optimize the technique and develop design parameters. A special test of this technique will also be extended to the Plastisol Plant. Recovery Compressors - Priority I (P. Scheiner ) The prime sources of leakage in this troublesome area are: 1. Compressor Packing This problem is being dealt with from an OSHA point of view by exhausting the VCM leakage via a blower through a high stack. Engineering will look at installing a nitrogen chamber so that the leakage can be contained. ) 2. Valve Positioning Bolt L. Iszak has altered some features of the bolt and the screw down nut as well as changed the gasketing material from lead to Teflon. The prelimin ary results are encouraging. 3. Valve Cover Machining down the valve cover gasket seat as well as making an "0" ring groove in combination with the use of Teflon gaskets has shown early good results (two weeks of no leakage-). L. Iszak will convert one Burlington compressor to incorporate the de signs above and will monitor its performance over the next thirty days. Compressor Isolation - Priority II (P. Scheiner ) If the above techniques work, then the need for isolating the compressors from the rest of the process building may not be there. If it does not work out, then we may have to open up the process building around the compressors and put in an internal wall and shroud the compressor heads with exhaust hoods. COLORITE 01X203 Page 3 Canned Pumps - Priority I (P.L. Wilson) Engineering (P.L. Wilson) will look further into availability of suitable pumps. If there is no single pump to do the job, alternates such as parallel or series configuration using multiple pumps are possible. P.R. Scarito will define which pumps are a problem at Burlington and J.T. Sweeney will do the same for Flemington. Vent Condenser Exhausts - Priority 1 ( - E, Schwartz) Engineering will begin a design for a Carbon Adsorption system to handle this and other VCM laden streams. Gasketing (Priority I) (E. V. Schenke) Ed Schenke has issued a gasketing specification. Copolymer Weigh Scale Area ( J.W, Porch) P.E. will investigate with the plant people the causes of excursions in this area and make recommendations. Master Mix Tank Drainings ( J.W. Porch) The proposal to put drainings into #7 blend tank and the vapor emissions from it will be reviewed by P.E. Cake Breaker Area Excursions (P.R.Scarito, W. Miringoff) P.R. Scarito to look into the background of the problem and let W.M. know the details. Plastisol Dryer Stacks (W. Miringoff) Aiming the exhaust up rather than sideways has reduced VCM readings in the bagging area. Evaluation of the need to extend further will be done by W. Miringoff. Tower Drainings (P.R. Scarito, J.W.Porch, W. Miringoff) The problem of how to handle tower wash downs and poorly transfering batches was discussed. Normally these problems result in the material washing onto the floor and raising the general VCM level in the plant significantly. A number of alternative methods were briefly discussed (use of in line mixers ) to transfer lumpy batches, putting the washings into the product in the stripper, etc.) P.R. Scarito will review the problem with his staff and further meetings with P.E. will be held to consolidate a design approach. / yn * "w y/ WM: jt /ty ' COLORITE 011204
