what is the difference between gc pro box and gc pro key

The line is equipped with pigging facility. The gas is compressed through a three-stage reciprocating compressor.HP Compressor PackageHP Gas from GC-16 is branched off through a new HP Scrubber to a new HP gas transfer line (approximate distance 3.5 KM) between GC-16 and TP-4 near GC-28. The scrubber is provided with automatic level control valves and collected liquids are routed to the LP Compressor Closed Drain Header.The GCP LP Compressor compresses the incoming gas from 20-60 psig to 270-300 psig and transfers the discharged gas to a 30' HP compressor suction manifold.

The LP pig launcher relief goes to the existing flare in GC-16.The Common LP Scrubber is designed for handling liquid slug during pigging and normal operation. The pig receiver and all other reliefs including common LP scrubber relief shall be integrated into the flare header of the GCP. at either end of the pipeline (namely in the vicinity of GC-16 and TP-4). The LP gas transfer line carrying the LP+TV of GC-16 is routed to a new LP Gas Inlet Manifold, near TP-4 with pigging facilities to absorb the slamming actions of liquid slug, etc. LP Compressor PackageSource of LP gas is either from GC-16 (LP+TV) or from GC-28 (from LP Separator KO Drum).
