Presented at the 2004 Annual Conference by
MANOJ KUMAR AGRAWAL, OIL & NATURAL GAS CORPORATION LIMITED, HAZIRA GAS PROCESING COMPLEX, INDIA
Hazira Gas Processing Complex (HGPC) is situated on the western coast of India sprawling in 705 hectares. The complex processes around 42 MMSCMD sour gas and 8000 m3 of sour condensate everyday received from offshore through 36” and 42” diameter and more than 230 km long submarine pipelines. HGPC has a gas/condensate receiving erminal and processing facilities which include Gas Sweetening Units, Gas Dehydration Units, Dew Point Depression Units, Condensate Fractionation units, LPG Recovery Unit, Kerosene Recovery Unit and Sulphur Recovery Unit. HGPC is producing LPG and NGL from their LPG recovery Unit and Condensate Fractionation Unit (CFU). As the NGL produced in CFU was found to contain Kerosene fraction, the idea of extracting SKO from the NGL produced in CFU was conceptualized and Kerosene Recovery Unit was commissioned in January, 1998 with designed capacity of 1.07 MMTPA of NGL in “series” mode of operation and 1.5 MMTPA in “parallel” mode of operation. During commissioning of KRU during Jan-Mar’98, it was observed that parallel mode of operation was not able to produce “on-specification” SKO (failing in flash point and
colour as per IS-1459-1974). Hence series mode of operation was resorted to with the capacity limited to 1.07 MMTPA only.
