Watson's Memo to Mr. T. L. Carey July 12, 1971 on Vinyl Chloride Safety Association August 2, 197 1 H. L. Watson I am in agreement that someone from both the Calvert City and Escambia plants should attend the Vinyl Chloride Safety Association meetings. Both plants 1 believe can contribute to the purpose of the meetings and a representative from each location is needed to obtain a full understanding of the safety information available and to apply it to their plant location. Mr. Beech will represent the Escambia plant. A. K. McMillan AP00036040 i "f^crrix 7?-:xu3& PUT IT IN WRITING Date July 12 f 19 71 ToT. L. CareySubject Vinvl Chloride Safety Association From ( '( H. L. Watson _______________________ ) Take Action { ) For Your Approval ) For Your Comments ( ) As Requested _. ( ) ForYourlnfo { ) File { ) Discuss With Me ( ) Note & Return As you know and as we have discussed previously, we are maintain ing two memberships in the Vinyl Chloride Safety Association, one under Air Products (John Barr) and the other under Escambia. The notice is out for the third meeting. I have discussed this with John and we both feel he should attend. We also feel that conditions permitting we should continue to have a representa tive from the Calvert location and the Pensacola location. When the original Association was being set up, everyone felt that the only limit should be on the total number of people attending which was set at 50, and, therefore, no limit on numbers from individual companies was set. They felt this ? would suffice so long as companies did not start sending five or six each. While we both feel it is advantageous both for the purpose of the Association and .the good of Air Products to have a representative from both our locations, we do feel obli gated to advise the Committee of the fact that we are now one Company and should not have two voting memberships. Any sugges tions or advise to the Association I trust would emanate from your office. X am merely listing here our feelings.

Kramer Mr. W. J. Kerler Mr. A. K. McMillan Mr. G. B. H. Speed A single tube one-pass heat exchanger was constructed from a 2" pipe of 304 S. S. and a 3M pipe of carbon steel for refrigerated cooling water. The vapor condenser thus constructed was placed in a reflux position over # 4 reactor. VCL vapors were ... allowed to rise through a 3" vessel nozzLe and isolation valve and up through a 3M - 304 S. S. riser to the inlet of the vapor condenser by natural convection. T^e* vapors were condensed* Liquid VCL flowed from the lower end of the condenser and returned to the vessel over a liquid seal leg and through a 3" vessel nozzle. Dial thermometers were placed in the refrigerated cooling water inlet and outlet lines as well as a water flow meter in the inlet line. The small condenser easiLy condensed all the vapors traveling up the 3" riser and the cooling water exiting the condenser jacket remained 64 F under the vapor condensation temperature. Heat removed under these condition amounted to 3, 486 BTU'fi per hour, or a temperature rise of 21 F for 166 lbs. per hour of cooling water. This equates to roughly 23 lbs. per hour of Liquid VCL condensed and returned to the reaction vessel by the vapor condenser. The calculated overall U was 12.15 BTXJ/hour - We had predicted an overalL U of 10 BTU/hour - ft^ - F from^mpirical equations. "'It is apparent from this that a S. S. vapor condenser in the range of at least 300 square feet would be required over each reactor before plant capacity would be very significantly affected. However, the following disadvantages come to mind: (a) Ail heat exchange equipment and repiping'would necessarily be 304 S. S. construction. Equipment aLso would be of speciaL design and fabrication. Costs .might be prohibitive. AP00036042 Mr, R. W. Beech 2- - February 25, 1971 "(b) There are no nozzle# .on our existing reactors large enough to carry enough vapors whereby removal of heat of vaporization wo uld be of any significance. (c) Our limited experience has shown that non condensables continuously buildup at the vapor condenser high point, regardless of how welL we pulled vacuum. This dramatically reduces the free flow of condensable YCL vapors and reduces heat removal. A continuous vent system and low-temperature vent condensing system; would be necessary to alleviate this problem, once again adding to the cost. (d) Tube fouling via polymer buildup could be deleterious to heat removal after perhaps only 2 or 3 batches. Frequent chemical cleaning might be necessary, costing time and productive yield. (e) If any of the condenser tubes ever plugged solid, it would be very difficult to get them re-opened since chemical cleaning is effective only when the buildup is exposed to free-flowing hot solvent. (f) Even if the above disadvantages were not so serious, the fact that we might charge greater batches of VCL. does not mean that we have any more available agitator power to drive bigger batches. We could only hope to charge more catalyst to batches of present sizes. This means shorter reaction cyde times, but in most cases we would be limited by drying and/or stripping times. / ms D. V.
