FIELD: process engineering. ^ SUBSTANCE: proposed invention may be used in oil, gas, oil processing and petrochemical industries. Method comprises bringing gas in contact with alkanolamine solutions in the presence of polysulphides stabilised by alkali. For this aqueous solution of mono colamine and methyldicolamine is fed in the following ratio of components, in wt %, i.e. mono colamine - 9-18%, methylcolamine - 24-42, and water making the rest. ^ EFFECT: higher degree to removal hydrocarbons from gases with low pressure (from 0,6 kgf/cm), increased selectivity in presence of carbon dioxide, reduced rate or corrosion and costs. ^ 2 tbl, 1 ex |
