FIELD: natural gas industry. SUBSTANCE: method involves subjecting gas to be conveyed to high-temperature treatment in the presence of oxygen or air at 300-500 C, pressure of 10-100 atm and oxygen concentration of 2-4.5% by volume for 0.2-2.0 sec, with only 2.7% of gas to be conveyed being subjected to thermal treatment and returned into manifold. EFFECT: increased efficiency.
