Abstract
A process for producing liquid hydrocarbon products includes converting a natural gas feedstock to synthesis gas, which is reacted, in a hydrocarbon synthesis stage and by a Fischer-Tropsch reaction, to produce a range of hydrocarbon product. An overheads vapour phase is separated from a liquid phase, and fed to a product condensation stage, where condensation of some components thereof takes place. A vapour phase, an aqueous phase, and a condensed product phase are withdrawn. The vapour phase is fed to a vapour phase work-up stage where a gas component comprising increased concentrations of CO and H2, relative to the vapour phase feed to the vapour phase work-up stage, is recovered, with this gas component being recycled to the hydrocarbon synthesis stage.
