METHOD OF PRODUCING UREA AND A PRODUCTION PLANT USING CO OBTAINED BY OXY-FUEL COMBUSTION Russian patent published in 2022 - IPC C07C273/04 

Abstract RU 2768935 C2

FIELD: technological processes.

SUBSTANCE: invention relates to a method of producing urea. Method includes a step for synthesis of urea by reaction of ammonia and carbon dioxide, wherein at least part of the carbon dioxide for the urea synthesis reaction is obtained in the oxy-fuel combustion process, where the oxy-fuel combustion process is a flameless oxy-fuel combustion process. Also disclosed is a urea plant containing a urea unit for producing urea by reacting ammonia and carbon dioxide, and an oxy-fuel combustion unit.

EFFECT: disclosed method increases efficiency of known method/plant for producing urea and flexibility thereof with respect to type and rate of supply.
