FIELD: purification of hydrocarbons.
SUBSTANCE: method comprises absorbing hydrogen sulfur by means of water alkaline solution and regenerating exhaust solution. The solution comprises methanol or ethanol, or mono-, di-, or triethanolamine. The absorption is carried out in a temperature range from the freezing temperature of the solution to +25°C at pH 7-14. The regeneration of the exhaust solution is performed by producing an inorganic compound with ferrous, or chrome, or active oxygen.
EFFECT: simplified method.
