Hydrogen Recovery From Hydrocarbon Synthesis Processes
US Patent:
7166643, Jan 23, 2007
Filed:
Mar 8, 2004
Appl. No.:
10/794084
Inventors:
Clifford M. Lowe - Moraga CA, US
Daniel Chinn - Concord CA, US
Daniel Chinn - Concord CA, US
Assignee:
Chevron U.S.A. Inc. - San Ramon CA
International Classification:
C07C 27/00
US Classification:
518726, 518700, 518722, 518709
Abstract:
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 reverse-selective membrane to provide a CO-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.

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 CO-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.

International Classification:
B01D053/62
US Classification:
423226000
Abstract:
A process and method for separating COfrom a gaseous stream such as natural gas. An ionic liquid comprising an anion having a carboxylate function is used as an adsorbent to selectively complex the COyielding a gaseous stream with a greatly reduced COcontent. The ionic liquid can then be readily be regenerated and recycled.
Aqueous Separation Of Syngas Components
US Patent:

Filed:
Apr 29, 2002
Appl. No.:

International Classification:
C07C027/06
US Classification:
518/728000
Abstract:
Unreacted syngas containing COfrom a Fischer-Tropsch synthesis reactor, a methanol synthesis reactor or a dual functional syngas conversion is scrubbed with an aqueous medium to adsorb at least some of the CO. At least a portion of the unreacted CO-depleted syngas is then recycled to the reactor. The aqueous medium containing absorbed COis treated to desorb CO. A CO-enriched stream and a CO-depleted stream are recovered. A portion of the CO-enriched stream may be recycled to a syngas generator while another portion is dissolved in an aqueous phase and disposed in a marine environment and/or a terrestrial formation. The CO-depleted stream preferably is used in the scrubber to absorb COfrom the unreacted syngas. The process reduces the amount of COreleased into the atmosphere while improving the over-all efficiency of the syngas conversion process.
