METHOD OF PRODUCING METHANOL FROM CARBON DIOXIDE Russian patent published in 2018 - IPC C07C29/151 C07C31/04 C07C1/12 C07C9/04 C01B3/38 

FIELD: oil and gas industry.

SUBSTANCE: process comprises the following stages: feeding a first feed stream with high content of carbon dioxide to at least one methanisation stage and converting the first feed stream with hydrogen under methanisation conditions into high content methanisation stream, supply of high content methanisation stream to at least one production stage of synthesis gas and converting it together with a second feed stream with high content of hydrocarbons to a synthesis gas stream containing carbon oxides and hydrogen, under conditions of synthesis gas production, supply of synthesis gas stream to methanol synthesis stage integrated in synthesis cycle, and converting it into the stream of methanol-containing product under methanol synthesis conditions, separating methanol from the stream of methanol-containing product and optionally, purifying methanol up to the stream of the final product of methanol and isolation of purge stream containing carbon oxides and hydrogen from the methanol synthesis plant.

EFFECT: invention makes it possible to dispose greenhouse gas with carbon dioxide to produce methanol using simple technology.
