Description
Изобретение относитс к очистке . газов от кислых компонентов, в частности ,от сероводорода и меркаптановы соединений и может быть использовано в газовой и химической промышленности . Известен раствор дл очистки газо от сероводорода, содержащий 10-25 алканоламинов (МЭА, ДЭА, ПЭА) D К Однако алканоламиновые растворы не обеспечивают очистку от меркаптановых соединений, кроме того затруднена очистка регенерируемого раствора и требуетс значительный расход алканоламинов, Известны также растворы дл очистки газов от сероводорода содержащие алкайоламины, воды и высшие аминоспирты с числом углеводородных атомов не ниже п ти в количестве до 10% вес 2 и растворы, содержащие диалкиловый эфир полиалкиленгликол 3. Эти растворы обладают низкой погло тительной способностью по отношению , к сероводороду и не обеспечивают ючистку газа от меркептановых соединений . Наиболее близким к предлагаемому изобретению по технической сущности и достигаемому результату вл етс абсорбент,, состо щий из смеси ди-или триэтиленгликол , моноэтаноламина и воды при следующем соотношении компонентов , вес.%.

Known solution for gas purification from hydrogen sulfide containing 10-25 alkanolamines (MEA, DEA, PEA) D However, alkanolamine solutions do not provide purification from mercaptan compounds, besides, cleaning of the regenerated solution is difficult and a significant consumption of alkanolamines is required. Gas cleaning solutions are also known from hydrogen sulfide containing alkaiolamines, water and higher amino alcohols with the number of hydrocarbon atoms of at least five in an amount up to 10% weight 2 and solutions containing dialkyl ether of polyalkylene glycol 3. These solutions have a low absorption capacity in relation to hydrogen sulfide and do not provide gas cleaning from merkeptan compounds. The closest to the proposed invention to the technical essence and the achieved result is an absorbent consisting of a mixture of di-or triethylene glycol, monoethanolamine and water in the following ratio of components, wt.%. Monoethanolamine 2-20 Di- or triethylene glycol 50-90 Water Else ti3. Its main disadvantage is that it has a low degree of purification from hydrogen sulphide and M1vrcaptan compounds. The aim of the invention is to create an absorbent having an increased absorption capacity for hydrogen sulfide and mercapta. 392728 The goal is achieved by an absorbent for the purification of gases from acidic components, including diethanolamine, diethyl glycol and water, which additionally contains triethylene glycol and triethylene glycol ethyl ether in the following ratio, weightD: Diethanolamine 20-25 diethylene glycol 30-35 O Triethylene glycol 10-15 Ethyl ether of triethylene glycol 20-25 Water Else. This absorbent has the following physico-chemical indicators.
