Main Article Content
Abstract
The sequence and criteria for selecting the optimal absorbent or their combined absorbents for selective purification of natural gas from acidic components are considered, as well as the problems of absorption purification technology. Today, various methods of alkanolamine purification in the preparation of oil and gas raw materials for industrial processing are studied, problems in the use of hydrogen sulfide, carbon dioxide, mercaptans as absorbents using mono- and diethanol solutions, and issues of their solutions are studied. The scientific article deals with the composition of alkanolamines for the use of a column-type absorber.
