Filed:

Sep 18, 2009

Appl. No.:

12/562182

Inventors:

Maria Balmas - Hacienda Heights CA, US
Henry Chan - Fountain Valley CA, US

Assignee:

BP CORPORATION NORTH AMERICA INC. - Warrenville IL

International Classification:

C10J 3/48
C10J 3/46
B01J 19/00
C01B 3/02

US Classification:

48 62 R, 48197 R, 422170, 252373

Abstract:

This invention relates to processes and apparatuses for reducing pollutants and/or producing syngas. The process includes the step of reacting a first stream with at least one sulfur compound to form a second stream with carbon dioxide, hydrogen sulfide, and a reduced amount of the at least one sulfur compound, and the step of recovering elemental sulfur from a portion of the second stream to form a third steam with the at least one sulfur compound, carbon dioxide, and a reduced amount of hydrogen sulfide. The process includes the step of directing at least a portion of the third stream to form a portion of the first stream.

Abstract:

This invention relates to processes and apparatuses for purifying greenhouse gases. This invention relates to processes and apparatuses for drying carbon dioxide and/or producing syngas. The process includes the step of contacting a greenhouse gas stream having a contaminant with a solvent stream to at least partially reduce an amount of the contaminant and form a used solvent stream. The process includes the step of using the greenhouse gas stream for carbon sequestration, enhanced oil recovery, industrial gas supply, or chemical synthesis and production.

Assignee:

Hydrogen Energy International Limited - Weybridge, Surrey

International Classification:

C10J 3/46

US Classification:

48197 R

Abstract:

Disclosed is a process to start-up, operate, and shut down a gasifier and an integrated gasification combined cycle complex with minimal sour gas emissions while additionally reducing the release of contaminants such as carbon monoxide, hydrogen sulfide, and nitrogen oxides. The process is accomplished by starting up with a sulfur free feedstock and by scrubbing any ventable sour gases free of sulfur contaminants prior to release of any such gases to the atmosphere.

Appl. No.:

12/594221

Inventors:

Craig Skinner - Newport Beach CA, US

International Classification:

F02C 3/28
C10L 3/08
F01K 23/06

US Classification:

60780, 48197 FM

Abstract:

Disclosed is a process to start-up, operate, and shut down a gasifier and an integrated gasification combined cycle complex without flaring while additionally reducing the release of contaminants such as carbon monoxide, hydrogen sulfide, and nitrogen oxides. The process is accomplished by scrubbing ventable sour gases and passing scrubbed sour gases and ventable sweet gases to a vent gas combustor for controlled combustion prior to release of any such gases to the atmosphere. Additionally, the gases are subjected to a CO oxidation treatment and selective catalytic reduction treatment prior to release to the atmosphere.
