DOW CHEMICAL LAD SOLVENTS / EDC 1 SOLVENTS PROCESS DESCRIPTION IN THE SOLVENTS PLANT. CARBON TETRACHLORIDE AND PERCHLQROETHYLENE ARE SYNTHESIZED WHEN A THERMAL CHLORINATION REACTION OCCURS BETWEEN CHLORINE AND VAPORIZED HYDROCARBONS. THE REACTION IS CONTROLLED IN A CHLORINE EXCESS BY THE ADDITION OP DILUENT (LIQUID OR VAPOR) TO THE REACTOR INLET LINE, AFTER THE REACTION IS QUENCHED, THE CRUDE REACTOR PRODUCT FIRST UNDERGOES A LIGHTS REMOVAL PHASE. IN THIS PHASE, THE CHLORINE REMOVED IS RECYCLED BACK TO REACTOR, AND THE HYDROGEN CHLORIDE REMOVED IS EITHER SENT TO THE VINYL II PLANT AS A RAW MATERIAL IN THE PRODUCTION OF ETHYLENE DI CHLORIDE DR SENT TO THE ACID SECTION OF THE PLANT AND USED AS A RAW MATERIAL IN THE PRODUCTION OF HYDROCHLORIC ACID. THE NEXT PHASE OF THE DISTILLATION PROCESS OCCURS WHEN THE CARBON TETRACHLORIDE IS DISTILLED FROM THE F'ERCHLOROETHYLENE AND HEAVIES. THE FINAL PHASE IN THE DISTILLATION SECTION OCCURS WHEN THE PERCHLOROETHYLENE IS DISTILLED FROM THE HEAVIES AND THE HEAVIES ARE SENT BACK TO THE REACTOR SYSTEM AS DILUENT. THE PRODUCTS CARBON TETRACHLORIDE AND PERCHLOROETHYLENE THEN UNDERGO THE FINAL PHASE OF THE PR0CE5S WHEN THEY ARE FILTERED IN CAUSTIC FLAKE AND ACTIVATED CARBON FILTERS TO REMOVE WATER AND OTHER REMAINING IMPURITIES. THE FINISHED PRODUCTS ARE THEN SENT TO TANK FARM STORAGE AND USED AS A SALES GRADE PRODUCT TO SUPPLY CUSTOMERS THROUGH OUT THE UNITED STATES. MB:12/89 DO 078399 OONFTDFNTTAl MK --""i on S.

THIS IMBALANCE MAY THEN RESULT IN HEAT EXHAUSTION, OR EVEN WORSE, A HEAT STROKE. BOTH ARE CAUSED BY REPEATED OR PROLONGED EXPOSURE WHICH WILL CAUSE THE FAILURE OF THE SWEAT REGULATING MECHANISM THAT COOLS THE BODY, WHEN HEAT STROKE OCCURS, IT IS IMPERATIVE THAT THE VICTIM BE TREATED IMMEDIATELY. IF TREATMENT IS NOT RENDERED QUICKLY, THERE IS A GREAT CHANCE THAT DEATH WILL OCCUR. IT SHOULD BE REMEMBERED THAT DURING THE HOT MONTHS OF THE YEAR YOUR SALT INTAKE SHOULD INCREASE, ESPECIALLY IF YOU ARE WORKING OUTSIDE. BY INCREASING THE AMOUNT OF SALT USED IN SEASONING YOUR FOOD, YOU WILL BE ABLE TO HELP YOUR BODY'S METABOLISM KEEP PACE WITH THE HEAT, AND THEREBY AVOID HEAT RELATED PROBLEMS.
