Overview

Used 20 MMSCFD cryogenic natural gas liquids plant. Designed by Randall. Plant commissioned in 1984. Inlet gas requirements: flow for each of two trains 20000 MSCF/D (14.65 psia @60F). Design pressure 600 psig, maximum pressure 800 psig. Water content 7 Ib/MMSCF. Inlet gas temperature 70F (design), 40 F (minimum). Residue gas pressure 800 psig @120F. End product: Single untreated demethanized stream with 1200 psig max pressure @120F. Methane content one-half(0.5) liquid volume percent of the total stream.
