METHOD FOR PROCESSING LIQUID GAS HYDROCARBONS USING 2-AMINO-2- (HYDROXYMETHYL) PROPANE-1,3-DIOLIC COMPOUNDS Russian patent published in 2018 - IPC C10G21/20 B01D11/00 B01D3/40 C07C7/10 C10L3/10 C10L3/12 

FIELD: chemistry.

SUBSTANCE: method for processing liquefied hydrocarbons containing acid gases to separate the above acid gases while minimizing the loss of the amine compounds includes the step of contacting liquefied hydrocarbons with an absorbent aqueous solution of the first amine compound, wherein the first amine compound has a structure in which either: a) R₁ is hydrogen and R₂ is selected from the group consisting of methyl, ethyl, n-propyl, isopropyl, n-butyl, sec-butyl, 2-hydroxyethyl or propane-2.3-diol, as well as mixtures thereof; or b) R₁ is selected from the group consisting of methyl, ethyl, n-propyl, isopropyl, n-butyl, sec-butyl, 2-hydroxyethyl or propane-2.3-diol, as well as mixtures thereof; or c) each of R₁ and R₂ is individually selected from the group consisting of methyl, ethyl, n-propyl, isopropyl, n-butyl, sec-butyl, 2-hydroxyethyl or propane-2.3-diol, as well as mixtures thereof.

EFFECT: reduction of amine loss during processing.
