FIELD: chemistry.
SUBSTANCE: invention relates to the purification method of liquefied hydrocarbons, such as the liquefied petroleum gas (LPG) or liquefied natural gas (LNG). The processing method of liquefied hydrocarbons, containing the acid gases to remove the mentioned acidic gases, while minimizing the losses of amine compounds, includes the contacting stage of the mentioned liquefied hydrocarbons with the absorbing aqueous solution of the first amine compound. The mentioned first amine compound has the structure:
, in which R1 is the hydrogen, propane-2.3-diol and its mixtures, and R2 is the propane-2.3-diol.
EFFECT: minimization of the amine compounds losses.
