US 12,098,658 B2 · Cogeneration of chemical products

Abstract

The present disclosure relates to cogeneration of power and one or more chemical entities through operation of a power production cycle and treatment of a stream comprising carbon monoxide and hydrogen. A cogeneration process can include carrying out a power production cycle, providing a heated stream comprising carbon monoxide and hydrogen, cooling the heated stream comprising carbon monoxide and hydrogen against at least one stream in the power production cycle so as to provide heating to the power production cycle, and carrying out at least one purification step so as to provide a purified stream comprising predominately hydrogen. A system for cogeneration of power and one or more chemical products can include a power production unit, a syngas production unit, one or more heat exchange elements configured for exchanging heat from a syngas stream from the syngas production unit to a stream from the power production unit, and at least one purifier element configured to separate the syngas stream into a first stream comprising predominately hydrogen and a second stream.

Dependent claims

A method for generation of one or more chemical products, the method comprising:

providing a heated stream comprising at least carbon monoxide and hydrogen;
cooling the heated stream comprising at least carbon monoxide and hydrogen such that heat therefrom is transferred to at least one stream and a cooled stream comprising at least carbon monoxide and hydrogen is provided;
subjecting the cooled stream comprising at least carbon monoxide and hydrogen to one or more purification steps so as to provide a first stream comprising predominantly hydrogen and a second stream that is a hydrogen-depleted stream;
and
carrying out one or both of the following:
processing the hydrogen-depleted stream so as to recover carbon dioxide therefrom;
combining at least a portion of the first stream comprising predominately hydrogen with nitrogen from a nitrogen source under conditions effective to form ammonia;
wherein the heated stream comprising at least carbon monoxide and hydrogen is a syngas stream that is formed in a syngas generation unit, and wherein heat is provided to the syngas generation unit from a separate unit that comprises a combustor.
