This productloa balance caa be achieved only by increasing the beneene feed rate. Numerous alternatives can be conceived on how this might be accomplished, bet before any evaluation can be made, it was necessary to determine vhat must be done to the existing plant to obtain continued production. Consequently, a Maintenance Survey was needed to determine the extant of the necessary repairs. In addition, the Phosphate Division Final Design Data Report for the existing Biphenyl plant, prepared in 1948, was out-dated and needed revising. To minimize the work load, these jobs were combined. ' ( This report describes in detail the equipment used' for the production of Biphenyl at Anniston. The equipment description is based on equipment inspection, firsthand knowledge, and oa- information supplied in Phosphate Division Engineering Depart ment Report Ho. 117, titled "Final Design'Data on 12 Unit ' Diphenyl Plant at Anniston, Alabama," dated December 23, 1948, by G. W. Jordan. The Maintenance Survey presented in this'report'is based on ' visual Inspection of each item and Includes only those repairs needed to put the plant in good operating condition. "Revisions to the process, equipment Improvements japing alterations, etc.j are'beyond the scope of"this report." These'alterations and/or additions will be presented in "subsequent reports and will be evaluated and Justified on their own merits. The words "Biphenyl" and "Diphenyl" are synonymous and are interchangeable in this report. RLH/fb ( 9/27/57 WATER PCB-SD0000046075 DESCRIPTION OF PROCESS I. INTRODUCTION Dtpheayl if produced by a pyrolysis reaction between two molecules of benzol in which one molecule of diphenyl and one molecule of!hydrogen are formed. The pyrolysis la brought about in this particular caae by stepwise vaporizing and super-heating benzol by bubbling the vapor through a aerie* of pot* filled with molten lead. The temperature to which the final lead pot or "converter" la heated determines the percentage of the benzol converted, which increases with higher temperature*. ' Several other pyrolysia reaction* also occur producing mainly terpheayl and also some more highly polymerized compounds. In addition, some free carbon is formed which deposits in the units causing considerable maintenance difficulties because of plug-ups. The percentage of terphenyl in the crude Biphenyl is rough ly the sane as the conversion percentage of the benzol. S7N0PS1S OF PROCESS Liquid benzol i shipped in tank car lots to the plant site and unloaded through the top dome by a siphon type pumping Arrangement delivering the benzol to storage tanka. The benzol delivery pipe la steam traced- and the storage tanks have steam coils to prevent the benzol from freezing in Che winter. Each of the five storage tanks has a sump pump for delivering benzol to the feed tank. These feed tanks are automatically refilled by a. continuous "let-down" control.Only one'of the storage tanks is allowed to feed the feed tank at a time. This choice of storage tank is manually determined by an operator. The single feed tank services all of the diphenyl units by means of a centrifugal pump fed from a bottom outlet in the tank. The benzol feeds a header where the individual feed are metered through orifices to the different units. Isopropyl alcohol is added to the benzene feed in concentrations of 0 to 0.5Z by weight, usually 0.15X is added. This isopropyl alcohol is pumped to the auction of the benzene feed pump where it Is mined and pumped to the omits. This material catalyzes the conversion, that is, a 40-60C. lower operating tempera ture. can be maintained when this material is added to the feed benzene. There are twelve diphenyl units of equal capacity, each consisting of a pipe coil vaporizer located In the flue gas exhaust stack, two preheater pots and a converter pot filled with molten lead and suspended in a firebrick setting for burning natural gas, and a fractionating column with a condenser and split flow box. In two of the units, Nos. 4 and 5, one of the preheater pots is replaced with a heat exchaagar. The units are numbered 2 through 13, there having been a No. 1 unit at one time. The present number of units were erected in five installments, Hot. 2 and 3 having been erected at dfffemnt tAndg, Nos. 4 and 5 together, Nos. 6, 7, 8, 9, and 10 together, and Nos. 11, 12, and 13 together eo that these groups are all DSW 462480 WATER_PCB -I 2. lightly different in some detail*. However, there are only actually two fuadamen tally different type* of unit. Ho*. 4 and 5 differing from the reat in that one of the preheater pot* i* replaced by a heat exchanger. Although, the heat exchanger effected a gaa savings aa predicted, it proved impractical due to carbon formation fouling the tabes and the idea was abandoned cm the subsequent unit*. After the benrol feed has been metered through an orifice, it passe* through the vaporiser pipe coil in the flue gas exhaust stack where the liquid benzol ia vaporized sad at the same time recover# some of the heat from the exhaust flue gases. The benzol vapor ia then babbled through molten lead ia the two preheater pots in series and the temperature stepped up to the pyrolysis reaction tempera ture. The hot vapors are converted to 10-301 diphenyl at they leave the converter pot, which ia similar to the preheater pots except that the molten lead is very carefully controlled at the desired reaction temperature, usually between 750 and 810C. The temperature ia ndjuated to give the percent, conversion needed to maintain the balance between Biphenyl and Saatowax needed to meet sales demands. After leaving the converter, the benzol and conversion products pass first through a lead trap (which is essentially a wide place in the line) for removing .entrained lead and then enter the bottom plate of a fractionating column. A considerable amount of carbon'adheres to the pipes between the converter and tl lead trap, and the lead trap and the fractionating column, necessitating the re moval and cleaning of the pipes every one to six souths. The super-beat in the vapors from the converter is utilized ia a fractionating column to effect a partial separation of the benzol from the conversion products The conversion products are later completely separated ia a batch distillation. The column top is maintained at(10Q C. by refluxing the condensed benzol vapors back to the top plate. The conversion product and same benzol is condensed in the column and allowed to overflow from a carbon trap on the bottom of the column to a crude diphenyl catch tank, for storage prior to batch distillation. The overhead vapors from the column are cooled by a partial condenser and the liquid benzol drained to a rotaweir for spitting the flow into reflux and benzol overhead which ia "run back" to the benzol feed tank by gravity. The rotaweir ia used to adjust the ratio between reflux and overhead. There are five differently sized and designed groups of condensers, a new design having been made for each install ment af units as mentioned earlier, and n different design used to replace some had condensers. In addition, these condensers have been shifted from one unit to smother to facilitate cleaning and repairing condensers. . The conversion product hydrogen, saturated with benzol vapor, la bled off from the condenser and rotaweir, collected in a common header, and passed through six coolers, connected in parallel, where soma of the benzol ia condensed and allowed to run by gravity back to the auxiliary feed tank. From the coolers the saturated hydrogen gas ia passed to a collecting tank in which more of the benzol condenses out and is drained to the benzol pump tank in the compressor room. The hydrogen from the collecting tank is compressed in two stages to 250-300#/in. . An intercooler and aftarcooler condenses the benzol vapor after each stage. . This benzol is collected in pressure receivers after each stage and periodically DSW 4624S1 WATER_PCB 3. blow by the hydrogen pressure oxer imto the pump task for return to the bemxol feed task. The hydrogen la -rested to the atmosphere or alae used la the wamufacture of EB-40, HB-20, etc. . Ia the aacoad type of unit (Hog. 4 tad 5) the flow of aaterltl ia eateatltlly the aiae aa that described abort except the vaporised benrol feed merging from the vaporizer coll paaaea through a heat exchanger ia Ilea of me of the preheaters. Tha conversion products aad beazol from the coaverter pot are also passed through the heat exchanger, coastercurrent to the benzol feed, thus transferring sensible heat fro the converted gases to preheat tie feed. The conversion products and vapors fro the converter pot then pass on to a colons as ia the case with the other units. Some of the onits have been altered since their installation. Unit So. 4 is being equipped witb a 4 foot extension on the converter. This exten sion to the converter will act. aa a sojourn section. This addition reaction space will provide additional reaction tine and pernit a temperature redaction of 30-60C. in the converter while maintaining the same percent conversion. This reduced temperature will Minimize carbon formation and reduce the heat exchanger fouling and unit clean-outs. The lead traps will b eliminated. Unit Ho. 11 has a large coil in the lower section of the column which acts aa a vaporizer. The flow is through tha large coil, the standard vaporizer coil in the stack, the three pots, and to the column. The hot gases fro the converter pot heat the benzene ia tha large coil and vaporize the benzene. The recovery of heat fro the converted gas stream has permitted an increased benzene feed rate of about 100 gallons per hour. The Increase Is due to better utilization of the heat input and the reduced heat load on tha column and condenser. Room for this large coil was made available by removing the two lower bubble cap plates from the column. Units Hos. 12 and 13 are equipped with this large coil but the coil is being by passed because the units surged sad caused excessive pressures throughout the unit, thus blowing the gaskets around the top of the preheater and converter pots. Ho. 11 unit also surges occasionally but since Ho. 11 unit Is equipped with a sojourn pot (the same as will be installed on Ho. 4 unit), the added space provides a cushion to absorb the sudden, expansion caused by rapid vaporization of benzene in the large coil. Ho. 11 unit Is being equipped with an automatic reflux control which will control the reflux rata to maintain a constant vapor temperature on tha third plate from the top of the column. Each unit is equipped with two orifice plates between the converter and column. These orifice plates are sized to give a pressure drop of about 40 psig aad thereby permit an increased pot operating pressure, increased . soujoum time, and a reduced operating temperature and minimize lead carryover from both entrainment and lead vaporization. The diameter of these orifices are 1.031 and 1.014 inches, the larger orifice being upstream fro the smaller one. DSW 462482 WATER PCB-SD0000046078 4. The tmp product from ell the columns is collected by gravity Is two crude diphenyl catch tasks. The pipisg to the task* ia steam jacketed to prevest the diphenyl from freezing asd haa a liquid trap to prevest vapor* from entering the catch task from the column. The tasks are vested iato the hydrogem header to equalise the pressor*. Tha two hatch still* each, consist of a horizontal, cyliadrical task surmounted by a fnctioaatiag column, a submerged Rums ay pump, and a gas fired coil heater. The pomp circulates the still charge from the task, through the coil heater aad back to the task. The rata of distillation of the crude diphenyl Is con trolled, by the combustion rate of natural gas is the gas fired heater, which is controlled by an adjustable automatic temperature recorder aad controller so as to give a temperature rise of 20-25C. betvaaa islet aad exit temperatures of the still charge through tha heater coil. If as attempt is made to increase the temperature rise above 25C., the coil becomes plugged with carbon. The vapors from the still are separated in a fractionating column. The first cut fra the column at 80C. is henrol which ia returned by gravity to a catch tank for subsequent return to the benrol feed tank ot recycling through the diphenyl units. The benzol cut ia not run directly back to the feed tank because of the possibility of not cutting the column at the proper time and allowing some con tamination to run back with the benzol. The next fraction, distilling between 80 and a distillate crystallizing point of 68.6C. is called "heads" and consists of light oils with boiling points nearing that of diphenyl. The diphenyl fraction is collected until tha temperature in the still pot reaches 340-350C. The tail cut Is collected until the distillate vappr temperature in the top of the column reaches 300C, The various distillation cuts are made with these reflux ratios: Benzol Cut Head# Cut Biphenyl Cut Tails Cut .- 201 501 201 151 The high boiler, remaining in the still as residue, ia pumped to the high boiler catch tank from which it is run into 55 gallon drums for storage or pumped to the Santowax still or Santowax storage tank. In order to prevent freezing of diphenyl In the condenser at the top of the fractionating column, the conseaser cooling water wait be at a temperature near the malting point of diphenyl (158?.). The flow of pond water ia adjusted to prevent freezing of the product. It ia generally necessary only to cut back the flow of pond water at the end of e distillation. The diphenyl production is measured in a catch tank and pumped te storage tanks or tank cars by a 2" Rumsey vertical lump pump. The heads and tails are collected and charged back to the next still batch. oSnN 462483 WATER_PCB-SD0000046079 5. GENERAL DISCUSSION The carbon formed i the diphenyl units partly deposit* 1* the pipe after the coaverter units, through the lead trap, La the pipe after the lead trap, and la the ffactionatlag coltwn. Theae pipe* become plugged with carbon aad must he dis^Mtled aad cleaned every one to six months. The lead trap and frac tionating column are cleaned out at more infrequent interval*. This so called "carbon" deposit analyzes as follows: Lead .......................................... Insoluble in HHO^....... (carbon included).... Insoluble, ignited............ Iron oxide, insoluble... Carbon, combustion........... 56.51 42.71 18.51 0.71 28.91 As much of this piping and equipment is above the melting point of lead, it la evident that the adhering carbon prevents coalescence of the molten lead drop lets. ' The amount of reflux returned to the fractionating column is controlled by the operator to maintain a temperature of about 100C. at the column top. The cooling vater to the condenser is operated s full capacity and as the heat duty of each unit is approximately the seme, it is apparent that the amount of reflux required vill vary according to the effectiveness of each condenser at a particular time. Vhea the temperature of the effluent vater exceeds 70C., the condensers are cleaned. The diphenyl units produce crude diphenyl by a continuous process vith a 24hour day operation. The number of units operated depends upon the diphenyl market or the maintenance required on the equipment. The crude diphenyl is collected and hatch distilled at intervals depending upon the rate of collection. The batch distilling requires 10-12 hours.

Generally the amount of water Is significant whem the let-down control is switched to a new tank and diminishes to a negligible amount after the storage tank has been used awhile. The recycled-benzol also contains traces of water and finally divided carbon. The water is lightly corrosive as it contains 0.031 sulfates, 0.03% chlorides, and some undetermined reducing compounds which will react with oxygen. It is necessary to return the recycled benzol to the feed tank rather than the storage tanks as it has been determined that the' recycled benzol contains some undetermined catalyst which upsets the operation of the diphenyl units. There fore, an effort is made to blend the recycled benzol in. with the fresh feed in a more or less constant ratio to maintain smooth operation of the unite. An automatic level (let-down) control is provided for maintaining the supply of benzol in the feed tank.

Item 212 Continued: 60 Heat Btluce: Controls: Size & Type: The condenser duty for *11 the unit* should be substantially the same and should consist approximately of the amount of super-heat in the vapors from the converter less the amount of heat lose from the surface of the fractiona ting column. This duty has been calculated to be about 625,000 BTTJ/hr. average based on a study as reported in a memo to Mr. J. F. Reeves, 5/25/48 written by Mr. G. W. Jordan. The present system, of control is to run the condenser with the water valve wide open and the split flow box adjusted to maintain the top of the column at 100C. The temperature of the cooling water and the efficiency of the condenser therefore deter mine the rate of benzol flow through the shell and the cooling water outlet temperature.
