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 H/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 COand H. After that, COand Hare separated and discharged. Part of obtained His applied as flow of hydrogen A. The other part of His 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.20 cl, 2 dwg |
