FIELD: oil and gas industry.
SUBSTANCE: invention can be implemented in oil and gas producing and oil refining industries. For preliminary partial purification 4-10% solution of hydroxide of alkali metal in volume of 0.01-0.02 m3 per 1000 nm3 of hydrocarbon products is introduced into transporting pipeline 1. Mixture of hydrocarbons is directed from pipeline 1 to mixer 2, whereto water is simultaneously supplied under excessive pressure, temperature from 0 to 25 °C and 7-10 pH of solution. Mixture of hydrocarbons with water solution is supplied from mixer 2 to separator 3, wherein hydrocarbon gas is separated from water solution and liquid hydrocarbons and is directed to final purification into absorber 4.
EFFECT: facilitating efficient purification of hydrocarbon products simultaneously preventing hydrate forming, decreasing corrosion of process equipment and costs, and increasing ecological safety.
