WE HAVE A ISSUE WITH OUR PURCHASE TO CALCULATE THE SHRINKAGE FACTOR ON GAS VOLUME DELIVERED DUE TO HIGH HYDROCARBON DEW POINT AGAINST THE 30F AT SUPPLY PRESSURE AS STIPULATED IN THE GAS SALE AGREEMENT.
OUR COMPANY IS ASKING TO DEDUCT THE FRACTION OF C6+ IN SAMLL STEPS AND CALCULATE H/C DEW POINT AFTER EVERY STEP UNTILL IT REDUCES TO 30F AND EVEN IF C6 BECOMES 0 THEN START REDUCTION OF C5 AND SO ON . SUBSEQUENTLY PRCEDURE OF REDUCING THE HIGHER H/C CONTENT WILL BE SOPPED WHEN THE 30F DEW POINT IS ACHIEVED AND TOTAL AMOUNT OF H/C DEDUCTED WILL BE SUBTRACTED TO GET THE REDUCED VOLUME
HOWEVER, OUR CLIENT IS ASKING TO FOLLOW THE FLASH CALCULATION PROGRAM TO CALCULATE THE VAPOR FRACTION AT 30F AND SUPPLY PRESSURE AND SAME VAPOR FRACTION WILL BE USED AS SHIRNKAGE FACTOR OF GAS DELIVERED WHILE REMAING WILL BE CONSIDERED AS CONDENSATE
AS PER OUR OPINION DUE TO FLACH CALCULATION PROCEDURE LIGHTER END LIKE C1,C2,C3 WILL ALOS BE PRESENT IN LIQUID PHASE WHCIH IS NOT WRITE TECHNIQUE
PL GIVE UR OPINIOIN AND GIVE ANY REFERECE OR STANDARD IF AVAILABLE
