METHANOL PRODUCTION METHOD Russian patent published in 2023 - IPC C07C29/152 C07C31/04 C01B3/36 C01B3/48 

FIELD: methanol production.

SUBSTANCE: present invention relates to a process for producing methanol from natural gas. This includes the following stages: synthesis gas is obtained by combined matrix and steam conversion of natural gas in an autothermal reforming reactor at a pressure of 1-5 atm, oxygen is used as an oxidizer, and the oxidizer excess ratio is 0.32-0.34, water vapour is also mixed in at a natural gas/steam molar ratio of 1 to 1. Next, the resulting synthesis gas is cooled to a temperature of 35-40°C, dried, compressed to a pressure of 40-45 atm, heated to a temperature of 200-210°C and sequentially served in two flow-type isothermal tubular methanol synthesis reactors.

EFFECT: obtaining methanol with a concentration of 85-90 wt.%, with a low residual CO content in unreacted synthesis gas, as well as reducing energy costs associated with compressing synthesis gas with a high nitrogen content, increasing specific productivity, and hence reducing capital intensity stages of methanol synthesis, and the reduction of soot formation at the stage of obtaining synthesis gas.
