COMPLEX INSTALLATION FOR GAS PROCESSING Russian patent published in 2014 - IPC C01B3/02 C01B3/48 C01B3/50 C01C1/04 C10G2/00 C07C29/151 

FIELD: chemistry.

SUBSTANCE: invention can be applied in chemical industry. Method of simultaneous obtaining hydrogen flow A, suitable for obtaining product A; enriched with hydrogen flow of synthesis-gas B, suitable for obtaining product B, depleted of hydrogen flow of synthesis-gas C, suitable for obtaining product C; and optionally, flow of carbon monoxide D, suitable for obtaining product D, from single flow of synthesis-gas X, characterised by the fact that single flow of synthesis-gas has optimised for production of product B molar ratio of synthesis-gas, determined as ratio H₂/CO. Single flow of synthesis-gas X is divided into flow of synthesis-gas X1, flow of synthesis-gas X2, flow of synthesis-gas X3 and, optionally flow of synthesis-gas X4. Flow of synthesis-gas X1 is subjected to stage of realising reaction of water gas conversion aimed at conversion of CO, present in flow of synthesis-gas X1, and water in CO₂ and H₂. After that, CO₂ and H₂ are separated and discharged. Part of obtained H₂ is applied as flow of hydrogen A. The other part of H₂ is connected with flow of synthesis-gas X2, which after that is applied as hydrogen-enriched flow of synthesis-gas B. Flow of synthesis-gas X3 is applied as depleted of hydrogen flow of synthesis-gas C. Optionally flow of synthesis-gas X4 is processed in order to remove carbon dioxide and hydrogen from it. Obtained flow of carbon monoxide is applied as source of carbon monoxide of flow D.

EFFECT: invention makes it possible to reduce total emissions of carbon dioxide.
