CYCLOHEXANE OFF-LOADING PROCEDURES
SAFETY AND ENVIRONMENTAL: CYCLOHEXANE IS A FLAMMABLE LIQUID AND IS LIGHTER THAN WATER. AVOID INHALATION AND SKIN AND EYE CONTACT. THE TLV IS 300 PPM.
SAFETY EQUIPMENT: STANDARD PLUS MONOGOGGLES AND RUBBER GLOVES.
PROCEDURE: SEE ATTACHED DRAWING FOR REFERENCE
- GRAB A SAMPLE FROM THE TANK TRUCK.
- HAVE LAB PERSON (TERRY) RUN AN ANALYSIS TO ENSURE QUALITY.
- RED TAG SYSTEM (3 TAGS - SEE DRAWING) - CLOSE THE CYCLOHEXANE CONTROL VALVE AND MANUALLY BLOCK IN AND TAG AT TANK.
- ENSURE THE M2 LINE IS BLOCKED IN AND RED TAGGED.
- BLOCK AND TAG BLOCK NITROGEN TO D-100A.
- DEPRESSURE TANK TO DRY VENT HEADER. IF LOAD ON THROX IS NOT TOO HEAVY, OPEN VENT BYPASS VALVE TO SPEED UP VENTING.
-THE TRUCK DRIVER SHOULD HAVE ALLTHE HOSES AND CONNECTIONS. CONNECT THE LOAD HOSE TO THE VALVE THAT TEES OFF THE M2 ADDITION UNE.
- BEFORE OPENING VALVE TO BEGIN OFF-LOADING, INFORM BOARDMAN AND HAVE HIM SET THE HIGH LEVEL ALARM TO 80 %. A DOW PERSON MUST REMAIN OUTSIDE TO MONITOR THE OFF-LOADING PROCESS.
- OPEN THE FILL VALVES AT THE TANK AND BEGIN OFF-LOADING TRUCK.
JOHN SACKS 1 0/8/90
DO A 033277 CONFIDENTIAL
- WHILE OFF LOADING, BOARDMAN SHOULD OCCASIONALLY MONITOR PRESSURE. THE ALARM ON TDC IS SET FOR 60 PSIG AND THE RELIEF VALVES BLOWS AT 160 PSIG.
- AFTER THE JOB IS FINISHED, PULL RED TAGS AND LINE UP SYSTEM. MAKE SURE HOUSEKEEPING IS DONE ON THE AREA. THE DRUM SHOULD BE PRESSURED BACK UP TO APPROXIMATELY 30 PSIG.
- CHANGE FILTER AT THE CYCLOHEXANE MAX FLOW METER. THE FILTERS ARE LOCATED IN THE INSTRUMENT SHOP.
- ADD M2 TO THE DRUM UP TO THE LEVEL DESIGNATED BY AREA ENGINEER.

PER/TET ACID LINE
IN ORDER TO DETERMINE WHETHER PER/TET ACID CAN BE USED WITHOUT AFFECTING THE HYDROCHLORINATORS, WE WANT TO HAVE ATRIAL RUN BEFORE THE TURN AROUND. SINCE THE PURIFICATION HEADER PRESSURE RUNS 100 PSIG HIGHER THAN THE PER/TET HEADER AND THERE WAS NO CONTROL VALVE, WE INSTALLED A NEW FLOW CONTROL RUN THAT TIES IN DOWNSTREAM OF THE CMP PRESSURE CONTROL VALVE AND UPSTREAM OF THE EBV. A NEW ORIFICE PLATE WAS INSTALLED ON THE METER RUN DECK ALONG WITH NEW FLOW AND PRESSURE TRANSMITTERS. THE CONTROL VALVE IS A VALTEK BELLOWS SEAL VALVE AND THE PER/TET ACID WILL BE FLOW CONTROLLED USING ONE OF THE METER RUN FLOW TRANSMITTER*
THE FLOW CONTROLLER WAS PUT IN GROUP 1, SLOT 7 ON THE TDC. THE REDUNDANT METER RUN FLOW WAS PLACED NEXT TO IT IN SLOT 6 AND E-61 OUTLET TEMPERATURE WAS MOVED FROM SLOT 7 TO SLOT 5. THE TWO V-70 TEMPERATURES HAVE BEEN MOVED FROM SLOTS 5 AND 6 IN GROUP 1 TO SLOTS 7 AND 8 IN GROUP 73. THE PRESSURE ON THE PER/TET ACID LINE CAN BE FOUND IN GROUP 109, SLOT 7.
/{L/45 orJ
FLOW SHEET 150 CONTAINS AN OVERALL PICTORIAL OF THE AHCL HEADERS (SEE ATTACHED DIAGRAM). THE ACID FROM THE MIRACLE COLUMN ALONG WITH TANK VENTS AND LIQUEFACTION VENTS CAN GO TO VINYL II, GO TO CMP, BE ABSORBED TO AQUEOUS AT SOLVENTS, AND/OR BE SCRUBBED WITH CELL EFFLUENT AT SOLVENTS. THE HEADER PRESSURE IS CONTROLLED AT APPROXIMATELY 110 PSIG IN ORDER TO GET INTO THE VINYL HEADER.
WE PLAN TO SET A PER/TET ACID FLOW RATE AND TO CONTROL THE CMP HCL HEADER PRESSURE BY MAKING UP ACID FROM HCL PURIFICATION. IN OTHER WORDS, WE STILL PLAN TO USE THE OLD HCL PRESSURE CONTROL VALVE TO CONTROL THE HEADER. REMEMBER THE PER/TET HEADER ONLY RUNS ABOUT 110 PSIG; THEREFORE, AS THE PRESSURE DROP INCREASES IN THE R-250'S AND THE CMP HEADER PRESSURE IS RAISED, IT WILL BE MORE DIFFICULT TO IMPORT PER/TET ACID.
SOME WORDS OF CAUTION: IF THE MIRACLE COLUMN,C-510, HEATS UP, THERE IS A VERY STRONG LIKELIHOOD THAT CHLORINE WILL BE CARRIED OVERHEAD AND INTO THE HEADER. FLOWSHEET 150 ON THE PICS WILL MONITOR THE MOST CRITICAL MIRACLE COLUMN TEMPERATURES. ALSO, SOLVENTS HAS A AOV (AO-421) ON THE
00 A 033784 OONF T DFNTT Al.
HEADER TO CMP AND VINYL II THAT AUTOMATICALLY SLAMS SHUT WHEN THE C-510 TEMPERATURE GETS TOO HOT. WE ALSO WILL MONITOR AO-421 VALVE POSmON AND THE C-510 OVERHEAD CHLORINE ANALYZER . IF VINYL II IS TAKING PER/TET ACID AND THE AOV SLAMS SHUT, THERE IS THE POTENTIAL OF BACKING UP VINYL II ACID TO CMP. AS A RESULT, AS SOON AS AO-421 CLOSES, BLOCK IN THE PER/TET CONTROL VALVE AND MANUALLY BLOCK IN THE CONTROL LOOP IN THE FIELD. FOR THIS TRIAL RUN WE WILL START OUT WITH ABOUT 50 MLB/DAY AND SLOWLY INCREASE IT UNTIL ABOUT 100 MLB/DAY. THE RUN WILL LAST ABOUT 5 DAYS TO SEE WHAT BYPRODUCTS ARE MADE. WE PUN TO SEE MORE PHOSGENE AND ACIDITY IN THE Ml FORWARD, BUT JUST HOW MUCH WE DO NOT KNOW. WE DO NOT EXPECT THE CHLORINE TO CAUSE ANY PROBLEMS IN LOW PPM CONCENTRATIONS, BUT R & D WILL GET INVOLVED IF WE SEE ANYTHING ABNORMAL BECAUSE OF PICL COMMUNICATION PROBLEMS, THERE IS A GOOD CHANCE THE CRITICAL SOLVENTS' PARAMETERS, MENTIONED ABOVE, WILL NOT BE TRACKED ON FLOWSHEET 150 DURING THIS TRIAL RUN. AS A RESULT, IT IS EXTREMELY IMPORTANT THAT COMMUNICATION WITH BOTH VINYL II AND SOLVENTS IS EXCELLENT.
