THE SALT MINING/37ORAGE TECHNOLOGY CENTER RECOMMENDS THAT THE DECOMPOSITION SUPPRESSOR BE PLACED BETWEEN THE WELL AND ALL ETHYLENE EQUIPMENT SUCH AS METER RUNS, SAMPLE 5VSTEMS, FIG TRAPS, COMPRESSORS, AND ETHYLENE DRYING AND PROCESSING EQUIPMENT. THE PURPOSE IS TO SNUFF OUT A DECOMPOSITION THAT MAY HAVE STARTED AT THIS EQUIPMENT BEFORE IT ENTERS THE WELL. FOR WELL ND S THERE WILL EE NO ETHYLENE EQUIPMENT BETWEEN THE BECOME SUPPRESSOR AND THE WELLHEAD.
THE TECH CENTER RECOMMENDS THAT THE TEMPERATURE SENSOR BE LOCATED UPSTREAM OF THE ETHYLENE EBV FARENOUGH TO ALLOW THE EBV SUFFICIENT TIME TO CLOSE. FOR WELL NO. B TWO TEMPERATURE SENSORS ARE PLANNED. ONE WILL BE 175 FEET AWAY AND THE OTHER 1000 FEET AWAY THE TEMPERATURE SENSOR THAT IS 175 FEET AWAY IS ON THE WELL NO. S METER RUN AND IS DESIGNED TO SENSE A DECOMP THAT HAS GOTTEN TO WELL NO.

THE SENSOR 1000 FEET AWAY IS DESIGNED TO SENSE A DECOMF THAT HAS COME DOWN THE LINE FROM PLAQUEMINE OR HAS ORIGINATED IN THE MASTER ETHYLENE METER RUN OR PJG TRAP AREA AT THE PIPELINE ENTRANCE TO BRINE PRODUCTION.

A DECOMPOSITION IF THE DECOMPOSITION SUPPRESSOR DOES NOT. THE DECOMPOSITION SUPPRESSOR IS POSITIONED BETWEEN THE TEMPERATURE SENSORS AND THE WELL AT A DISTANCE OF 110 FEET FROM THE WELLHEAD.
3. PROMIX WELL NO. 2 CONVERSION TO BRINE MINING
CONCERN: ESTABLISH ADEQUATE OPERATING DISCIPLINE TO ASSURE THAT DOWNSTREAM VALVES AND EBV'S ARE BLOCKED IN PROPER SEQUENCE TO AVOID BLOCKING IN HIGH PRESSURES.
RESPONSE: WELLHEAD EBV'S ARE CLOSED ON A HIGH PRESSURE TRIP SET AT 600 PSIG ON THE BRINE AND SAFETY STRINGS THE SAFETY STRING AND BRINE STRING FLOWLINES TO THE WELL ARE 300 LBS. FIFING SYSTEMS WHICH ARE GOOD FOR . 7?0 PSIG AT AMBIENT TEMPERATURE. ' 'THE TRIP AT 600 PSIG PROTECTS THESE 300 LB. FIFING SYSTEMS FROM HIGH WELLHEAD PRESSURES. EEV TRIPS ARE INVESTIGATED IMMEDIATELY, THEREBY NOT ALLOWING THE LINE TO SI AY BLOCKED IN AND TO PRESSURE UP.
THE BRINE PRODUCTION AMD HYDROCARBON STORAGE PROCEDURE FOR BLOCKING IN HYDROCARBON LINES, REQUIRES THAT THE BLOCKED IN SECTION MUST BE VENTED OR FLARED TO PREVENT OVERPRESSURE DUE TO HYDRAULIC EXPANSION.
CONCERN: REVIEW EBV MANUAL OVERRIDE SYSTEM CONFIGURATION AND PROCEDURES.
RESPONSE: PRESENTLY, BRINE PRODUCTION USES REVERSE ACTING FIRE SAFE GATE VALVES WITH AXELSON MANUKATIC ACTUATORS. THESE VALVES ARE FAILSAFE CLOSED VALVES THAT REQUIRE AIR TO OPEN. THE VALVE STEM HAS A MANUAL OVERRIDE HANDWHEEL THAT ALLOWS THE VALVE TO EE OPERATED WHEN THE VALVE IS IN THE AUTOMATIC CLOSED POSITION. LIMIT SWITCHES MONITOR THE POSITION OF THE VALVE ACTUATOR FISTGN. THE FULLY UF OR THE FULLY DOWN POSITIONS ARE THE ONLY ONES RECOGNIZED. IN THE AUTOMATIC OPEN POSITION THE VALVE ACTUATOR PISTON IS DOWN. WHEN THE VALVE ACTUATOR PISTON IS UP THE VALVE IS IN ONE OF THREE POSITIONS, AUTOMATIC CLOSED, MANUAL OPEN OR MANUAL CLOSED.
THEREFORE, ANY TIME THE VALVE DOES NOT INDICATE AUTOMATIC OPEN <ACTUATOR PISTON FULLY DOWN), THE VALVE IS NOT READY TO ACT AS AN EEV AND TO CLOSE ON EMERGENCY. THE OPERATING PROCEDURES DETAIL. THESE CONDITIONS, AND WHAT MUST EE DONE TO CHECKOUT AND READY AN EBV.

AUTHORIZATION REQUEST - PROMIX NO. 2 WELL CONVERSION TO MINING
THIS IS A REQUEST FOR *310 M CAPITAL TO CONVERT PROMIX NO. 2 WELL TO BRINE MINING IN ORDER TO INCREASE BRINE PRODUCTION CAPACITY BY 350 GPM. PROMIX NO. 2 IS AN IDLE HYDROCARBON STORAGE CAVERN WITH A PRESENT CAVERN SIZE OF* 64 MM BBLS. IT HAS RECOVERABLE SALT RESERVES OF 750*000 TONS OF SALT <2.5 MM BBL. CAVITY) BETWEEN 3300 FEET AND 2700 FEET. A BRINE CAPACITY OF 350 GPM CAN BE IMMEDIATELY REALIZED ON START-UP SINCE A 50 FEET DIAMETER CAVERN ALREADY EXISTS. AT 350 GPM THE CAVERN CAN BE MINED FOR TWO (2) YEARS BEFORE DEPLETING THE RESERVES.
PROJECT SCOPE
THE PROJECT INCLUDES VALVES* PIPING, INSTRUMENTATION AND CONTROLS FOR A MINING WATER LINE* A BRINE LINE AND A PROPANE LINE. THE WELL WILL USE PROPANE AS A HYDROCARBON PAD AND IT WILL BE INSTRU MENTED WITH TRIPS AND EMERGENCY BLOCK VALVES AS IF IT WERE A STORAGE WELL DUE TO THE PROPANE PAD. A WELLHEAD SPOOL WILL BE PURCHASED AND INSTALLED SINCE THE PRESENT WELLHEAD IS INCOMPLETE.
BENEFITS AND JUSTIFICATION
THE DEMAND FOR BRINE ON THE BRINE PRODUCTION PLANT IS 5720 GPM. THIS DEMAND IS BASED ON THE CHLORINE PLANTS AT CAPACITY <6.4 MM LBS/DAY CHLORINE) AND THE HYDROCARBON STORAGE WELLS <PROMIX AND HYDROCARBONS) BRINE REQUIREMENTS. BRINE PRODUCTION PRESENTLY HAS A CAPACITY OF 4500 GPM. THIS 1220 GPM SHORTFALL BETWEEN BRINE CAPACITY AND DEMAND IS THE JUSTIFICATION FOR THE IMMEDIATE CONVERSION OF PROMIX NO. 2 TO MINING.
D 005928
CONF.TDFNTTA!
THE BRINE CAPACITY OF BRINE PRODUCTION WAS UNEXPECTEDLY REDUCED BY 400 GPM DURING THE SECOND HALF OF 1985 BY 400 CPM DUE TO A CASING LEAK IN WELL NO. 4 AND A POTASH SEAM IN WELL NO. 16. DOW NO. 12 WITH 425 GPM BRINE CAPACITY IS SCHEDULED TO BE TAKEN OUT OF MINING IN JULY. 1986 AND CONVERTED TO HYDROCARBON STORAGE (LPG BACK-UP). BRINE WELL NO. IS CAPITAL WAS DELAYED FROM 1984 TD 1985. THIS DELAY MEANS THAT WELL NO. 18 WILL NOT BE UP TO ITS 850 GPM BRINE CAPACITY UNTIL SECOND QUARTER 1987 RATHER THAN SECOND QUARTER 1986.
WHEN THE CHLORINE PLANTS RUN AT CAPACITY. BRINE PRODUCTION CAPACITY IS EQUAL TO THE CHLORINE CELL DEMAND. THIS LEAVES NO SUPPLEMENTAL BRINE CAPACITY FOR HYDROCARBON STORAGE WELLS. WELL WORK OVERS, BRINE POWER CURTAILMENTS, OR CHLORINE CELL START-UPS.
PRESENT BRINE DEMAND IS SUMMARIZED AS FOLLOWS:
CHLORINE MANUFACTURE <6.4 MM LBS/DAY) 27% SUPPLEMENTAL DEMAND
4445 GPM BRINE 1275 GPM BRINE
TOTAL DEMAND
5720 GPM
SUPPLEMENTAL BRINE DEMAND AND CAPACITY ARE AS FOLLOWS:
SUPPLEMENTAL DEMAND
WELL WORK OVERS (CLIFTON 1 AND CLIFTON 6 CAVERN)
HYDROCARBON STORAGE WELLS BRINE MAKE-UP, POWER CURTAILMENT CHLORINE CELL START-UPS
1700 GPM
1500 GPM 750 GPM 750 GPM
TOTAL SUPPLEMENTAL DEMAND
4700 GPM
SUPPLEMENTAL CAPACITY <27% OF DEMAND)
1275 GPM
IT IS FELT THAT A SUPPLEMENTAL CAPACITY OF ONLY 27% OF THE TOTAL SUPPLEMENTAL DEMAND IS NEEDED DUE TO THE SURGE CAPACITY OF THE NORTH AND SOUTH BRINE PONDS.
PROMIX NO. 2 CONVERSION TO MINING IS NEEDED AS SOON AS POSSIBLE IN 1986 TO BOOST PRESENT BRINE CAPACITY AND TO ALLOW DOW NO. 12 TO BE TAKEN OUT OF MINING AND CONVERTED TO STORAGE.
DO 005929 C.ONFTDFNTTAl
SAFETY AND LOSS PREVENTION AND TECHNOLOGY
PROMIX NO. 2 WILL BE SET UP WITH HIGH PRESSURE TRIPS ON ALL THREE STRINGS (BRINE. MINING WATER. AND PROPANE). THE PROPANE STRING WILL ALSO HAVE A LOW PRESSURE TRIP. EACH STRING WILL HAVE A WELLHEAD WING VALVE (MANUAL) AND AN EBV (AUTOMATIC). ALL EBVS WILL CLOSE IF ANY OF THE TRIP SETPOINTS ARE EXCEEDED.
PROMIX NO. 2 IS COMMUNICATED WITH GRACE NO. 1. PROPANE WAS CHOSEN AS THE PAD FOR PROMIX NO. 2 SINCE GRACE NO. 1 STORES PROPANE. GRACE NO. 1 HAS BEEN IN PROPANE STORAGE FOR 3-1/2 YEARS. THERE HAS NEVER BEEN A PROBLEM WITH PROPANE MOVING FROM GRACE NO. 1 TO PROMIX NO. 2. PROMIX NO. 2 WILL BE MINED USING THE 3/4 POINT TECHNIQUE AS A SAFETY PRECAUTION. WITH THIS MINING TECHNIQUE THE BRINE WITHDRAWAL POINT WILL BE AT 3300 FEET. DEEPER THAN ANY PART OF GRACE NO. 1 CAVERN. THIS WILL INSURE PROPANE WILL NOT EXIT WITH THE BRINE.
AN ELECTRICAL CLASSIFICATION OF CLASS I. DIVISION II WILL BE ESTABLISHED WITHIN 25 FEET OF THE WELLHEAD IN COMPLIANCE WITH SAFETY AND LOSS PREVENTION GUIDELINES. THE WELL WILL HAVE A F&E INDEX OF 90 WITH A MAXIMUM PROBABLE LOSS OF *567 M BASED ON A MAXIMUM PROPANE INVENTORY OF 50,000 BBLS. THIS PROJECT HAS BEEN REVIEWED WITy^HE SAFETY DEPARTMENT. WBACTIV GIIDIICALCT-pejIllirT I LBatKB- THE SALT MINING/STORAGE TECH CENTER. ABfc. GROUPS SUPPORT THIS PROJECT.
ENVIRONMENTAL
THERE WILL BE NO NEW SOURCES OF HYDROCARBON EMISSIONS TO TM^^
ATMOSPHERE AS A RESULT OF THIS INSTALLATION OTHER THAN Ft&ATIVC
EMISSIONS IF EQUIPMENT FAILURE WERE TO RESULT. ALL BRINE THAT
LEAVES THE WELL WILL NORMALLY PASS THROUGH THE SOUTHMD
STACK AM=saaa308 SYSTEM. THE BRINE CAN ALSO BE ROUTED TO THE NORTH FLARE STACK.H. BOTH OF THESE SYSTEMS HAVE BSft RECENTLY
J
UPGRADED AND BOTH MEET \&LP GUIDELINES. THE PAD AROUND PROMIX
NO. 2 WILL BE DIKED, WITN THE COLLECTED WATER BEING RETURNED TO
THE MINING WATER SYSTEM. \THIS PROJECT HAS BEEN NBSMft WITH ENVIRONMENTAL GOH*ROL AND VhEY SUPPORT IT.
INDUSTRIAL HYGIENE
THERE WILL BE NO NEW CHEMICALS INTRODUCED TO BRINE PRODUCTION AS A RESULT OF THIS OPERATION. THERE WILL BE NO INDUSTRIAL HYGIENE PROBLEMS AS A RESULT OF THIS PROJECT. THIS PROJECT HAS BEEN REVIEWED WITH LOUISIANA DIVISION INDUSTRIAL HYGIENE AND THEY SUPPORT IT.
