HYDROGEN RECOVERY FROM HYDROCARBON SYNTHESIS PROCESSES |
摘要 |
The invention relates to a process for producing a hydrogen-rich stream from a hydrogen-depleted stream. More particularly, the invention relates to a hydrocarbon synthesis process, by way of example, a Fischer Tropsch process, from which both hydrocarbons and high purity hydrogen are obtained. The process comprises contacting the hydrogen-depleted stream with a first reverse-selective membrane and a second reverse-selective membrane to provide a C02-enriched permeate and a hydrogen-containing retentate. The high purity hydrogen is produced from the hydrogen-containing retentate. The high purity hydrogen thus obtained may be used in a process selected from the group consisting of upgrading hydrocarbons produced from the hydrocarbon synthesis process, hydrotreating a natural gas stream, recycling to the hydrocarbon synthesis reaction unit, high purity hydrogen production, catalyst rejuvenation, and combinations thereof. |
