EXTRACTION OF NATURAL GAS LIQUIDS AND COOLING OF TREATED RECOMPRESSED GAS

摘要

An apparatus for processing of natural gas feed gas NG comprises: an upstream natural gas liquid extraction part (11) using a distillation column (28), where natural gas liquids NGL are extracted from the bottom of the distillation column (28) and a treated natural gas stream can be taken from the top of the distillation column (28); and a compression and cooling part (21) where treated natural gas from the top of the distillation column (28) is compressed and cooled; wherein after the natural gas liquid extraction part (11) and before the compression and cooling part (21) the treated natural gas process stream passes through a pre-cooling part (31), which is used to generate cooling duty for the treated natural gas process stream NG' after it has passed the compression and cooling part (21).
