Filed:

Jan 14, 2011

Appl. No.:

13/007583

Inventors:

Steven Lee Krupa - Fox River Grove IL, US
Cedric R. Freeman - Houston TX, US
Jessy E. Trucko - Lake Forest IL, US
Jonathan Andrew Tertel - Mt. Prospect IL, US

Assignee:

UOP LLC - Des Plaines IL

International Classification:

C10G 19/08
C10G 19/00

US Classification:

208235, 208177, 208208 R, 208226, 208230

Abstract:

One exemplary embodiment can be a process for removing one or more disulfide compounds from a caustic stream. The process can include passing the caustic stream, previously contacted with a hydrocarbon stream for removing one or more mercaptans, through a column to remove the one or more disulfide compounds downstream of a mercaptan oxidation zone.

UOP, LLC - Des Plaines IL

International Classification:

B01D 53/02
F25J 1/00

US Classification:

62611, 95114

Abstract:

One exemplary embodiment can be a process for purifying a natural gas by using first and second adsorbers. The process may include passing a feed including the natural gas through the first adsorber to obtain a purified natural gas product, regenerating the second adsorber in a heating stage, and regenerating the second adsorber in a cooling stage. The heating stage may include separating a portion of the feed comprised in a regeneration gas, passing the regeneration gas to a dryer for removing water, heating the regeneration gas with a heater after exiting the dryer, and passing the regeneration gas to the second adsorber to regenerate the second adsorber. The cooling stage may include expelling at initiation of cooling at least a part of a fluid present in the second adsorber to the dryer to desorb water from a molecular sieve in the dryer, and cooling the second adsorber by circulating the regeneration gas bypassing the heater.

International Classification:

C07C 7/10

US Classification:

585833, 252189

Abstract:

One exemplary embodiment can be a process for removing one or more disulfide compounds from a caustic stream. The process can include passing the caustic stream, previously contacted with a hydrocarbon stream for removing one or more mercaptans, through a column to remove the one or more disulfide compounds downstream of a mercaptan oxidation zone. The caustic stream can be contacted with a solvent stream comprising one or more hydrocarbons in a column. The solvent stream can be passed to a plurality of beds for removal of extracted disulfides from the solvent over an adsorbent.
