A method of processing synthesis gas improves the quality of the synthesis gas by using a water gas shift reaction to increase the molar ratio of hydrogen to carbon monoxide (H:CO) in an efficient manner. A first steam of hot natural gas-based synthesis gas having a first higher molar ratio of H:CO is combined with a second stream of quenched synthesis gas having a second lower molar ratio of H:CO to provide a blend of synthesis gas having a third molar ratio of H:CO that is between the first and second molar ratios. A non-catalytic water gas shift reaction increases the molar ratio of H:CO to a fourth molar ratio that is higher than the third molar ratio, and can be about equal to or greater than the first molar ratio without supplying external heat.

Process using natural gas partial oxidation to condition syngas from gasification of other fuels

A process for recovering sulfur from a hydrogen sulfide-bearing gas utilizes an aqueous reaction medium, a temperature of about 110-150&#xb0; C., and a high enough pressure to maintain the aqueous reaction medium in a liquid state. The process reduces material and equipment costs and addresses the environmental disadvantages associated with known processes that rely on high boiling point organic solvents.

Aqueous process for recovering sulfur from hydrogen sulfide-bearing gas

A method and system for co-production of electric power, fuel, and chemicals in which a synthesis gas at a first pressure is expanded using a turbo-expander, simultaneously producing electric power and an expanded synthesis gas at a second pressure after which the expanded synthesis gas is converted to a fuel and/or a chemical.

Co-production of fuels, chemicals and electric power using turbochargers

A method and system for co-production of electric power, fuel, and chemicals in which a synthesis gas at a first pressure is expanded using a stand-alone mechanical expander or a partial oxidation gas turbine, simultaneously producing electric power and an expanded synthesis gas at a second pressure after which the expanded synthesis gas is converted to a fuel and/or a chemical.

Co-production of fuels, chemicals and electric power using gas turbines

A multi-stage UCSRP process and system for removal of sulfur from a gaseous stream in which the gaseous stream, which contains a first amount of HS, is provided to a first stage UCSRP reactor vessel operating in an excess SOmode at a first amount of SO, producing an effluent gas having a reduced amount of SO, and in which the effluent gas is provided to a second stage UCSRP reactor vessel operating in an excess HS mode, producing a product gas having an amount of HS less than said first amount of HS.
