Process to distill Fischer-Tropsch product

摘要

A process a process for processing a Fischer-Tropsch product comprising the following steps by separating three hydrocarbon product streams, a light stream (L1), a less light stream (L2) and a heavy stream (H1); feeding (L1) and (L2) to a first separator (S1), and feeding (H1) to a second separator (S2); separating in (S2) a light stream (L3) and a heavy stream (H2); feeding at least a part of the light stream (L3) to the first separator (S1); separating in (S1) a light stream (L4) and a less light stream (L5); feeding (L4) to a third separator (S3); separating in (S3) an off-gas and a light stream (L6). The recovery of C3+ hydrocarbons is maximized. Streams (L5), (L6) and (H2), which are almost free of CO, CO2 and H2O, may be subjected to hydrogenation and/or hydrocracking/hydroisomersation.
