FIELD: by-product-coking and shale-processing industries.
SUBSTANCE: gas mixture is composed of natural methane-containing gas (9-15 vol %) and smoke fumes obtained through combustion thereof (91-85 vol %). Combustion of natural gas containing at least 99% methane is carried out at air excess factor 1.03-1.05. Resulting smoke fumes are washed with water-alkali solution, cooled to temperature not higher than 50°C, and mixed with starting natural gas in centrifugal impeller machines at rotation speed at least 1000 rpm.
EFFECT: enhanced reliability and safety of process.
