Abstract: This disclosure discusses problems associated with using natural gas to produce a variety of synthetic hydrocarbon products by production processes that require syngas feedstocks with varying H2/CO and (H2?CO2)/(CO+CO2) ratios. A number of gas separation membranes are used to vary the composition of the feed streams to different hydrocarbon synthesis units so that different synthetic hydrocarbon products can be produced. The process supplies syngas to an integrated hydrocarbon processing system comprising a number of hydrocarbon synthesis units. Gas (usually a portion of a raw syngas stream) is routed through the separation membrane units, multiple H2-rich and H2-lean streams are produced. These H2-rich and H2-lean streams can then be combined in a controlled fashion to produce feed streams of the desired compositions for the various hydrocarbon synthesis units. A variety of liquid synthetic hydrocarbon products can be produced from a given syngas source as required by market demands.
