Abstract: A method and system for steam generation and purification is presented. The method includes receiving a fuel stream, a water stream, and an oxidant stream in a direct contact steam generation (DCSG) apparatus; and generating a gas mixture stream comprising steam and carbon dioxide (CO2) in the DCSG apparatus. The method further includes receiving at least a portion of the gas mixture stream in a membrane separator, and separating at least a portion of the steam from the gas mixture stream to generate a permeate stream. The method further includes recirculating at least a portion of the permeate stream to the DCSG apparatus; monitoring a CO2 content in the gas mixture stream; and discharging at least a portion of the gas mixture stream at an outlet of the DCSG apparatus as a product stream if the CO2 content is lower than a determined value.

Abstract: A method for ammonia synthesis using a water-gas shift membrane reactor (WGSMR) is presented. The method includes carrying out a water-gas shift reaction in the WGSMR to form a first product stream and a carbon dioxide (CO2) stream, wherein the first product stream includes nitrogen (N2) and hydrogen (H2), and a molar ratio of H2 to N2 in the first product stream is about 3. The method further includes separating at least a portion of the residual CO2 in the first product stream in a CO2 separation unit to form a second product stream, and separating at least a portion of the residual CO2 and carbon monoxide (CO) in the second product stream in a methanator unit to form a third product stream. The method further includes generating an ammonia stream from the third product stream in an ammonia synthesis unit. A system for ammonia synthesis is also presented.
