METHOD FOR PRODUCING SYNGAS WITH RECYCLING OF WATER

摘要

Disclosed is a production process for synthesis gas ("syngas") which can be used to generate power or as a chemical feedstock for, e.g. an ammonia plant, which process includes the steps of: partial oxidation of a carbonaceous feedstock to produce very hot raw syngas, quenching the very hot raw syngas with liquid water, reacting the carbon monoxide in the raw syngas with water to form carbon dioxide and hydrogen, condensing water out of the shifted raw syngas by cooling to heat up process make-up water, and recycling the condensed water and at least some of the heat of the heated make-up water to the quench.
