Description
Изобретение относитс к очистке газов от кислых компонентов, например COji; сернистых соединений , CS-z./ COS и др., кислорода, аммиака и осушки газов химически активньоми гог.-.огительными растворами и может использ.оватьс в химической и нефтехимической промышленности при производстве газовых смесей.This invention relates to the purification of gases from acidic components, for example COji; sulfur compounds, CS- z./ COS and others, oxygen, ammonia and gas drying of chemically active gas-containing solutions and can be used in the chemical and petrochemical industry in the production of gas mixtures.
Известны способы очистки газов от кислых примесей щелочными растворами , (например моно-, ди- или триэтаноламин ), в основном от двуокиси углерода и сероводорода 1,Known methods of cleaning gases from acidic impurities alkaline solutions (for example, mono-, di- or triethanolamine), mainly from carbon dioxide and hydrogen sulfide 1,
Известен способ удалени кислых примесей из газовых смесей путем контактировани газа с поглотительным раствором, содержащим соль щелочного металла, .амин и борную кислоту при 25-200с 21 .There is a known method for removing acidic impurities from gas mixtures by contacting the gas with an absorption solution containing an alkali metal salt, amine and boric acid at 25-200c 21.
Однако использование таких поглотителей усложн ет процесс и не позвол ет одновременно проводить очистку от кислорода и аммиака и осушку газов.However, the use of such absorbers complicates the process and does not allow for simultaneous purification from oxygen and ammonia and drying of gases.
Цель изобретени - упрощение процесса и возможность удалени из газовых смесей кислых примесей, кислорода и аммиака и глубокой осушки газов.The purpose of the invention is to simplify the process and the possibility of removing acidic impurities, oxygen and ammonia and deep drying of gases from gas mixtures.
Цель достигаетс тем, что в качестве органического поглотител используют алюминийорганические соединени общей формулы ,|, где R - алифатический алкил с числом атомов углерода от- 2 до 30, п 1-3, X - се , Вг, т ,OR,SR,OCOR, NRg. Указанные соединени используют с концентрацией, 2-100 вес.%.The goal is achieved by using as an organic absorber organoaluminum compounds of the general formula, |, where R is an aliphatic alkyl with the number of carbon atoms from 2 to 30, n 1-3, X - se, Br, t, OR, SR, OCOR , NRg. These compounds are used with a concentration of 2-100% by weight.
Пример. 40 л окиси углерода , содержащего, об%: СОg. 5,5, сернистых соединений 1,2, кислорода 2,5, аммиака 0,09, а также влагу (т,росы + 20°С), пропускают через 12 г-триэтилалюмини (0,104 г-моль) в 100 мл декана при 20-21°С и атмосферном давлении в течение 2 ч.Example. 40 liters of carbon monoxide containing,%: COg. 5.5, sulfur compounds 1,2, oxygen 2.5, ammonia 0.09, and also moisture (t, dew + 20 ° C), are passed through 12 g-aluminum triethyl (0.104 g-mol) in 100 ml of decane at 20-21 ° C and atmospheric pressure for 2 h.
После очистки окись углерода практически не содержит двуокиси углерода , сернистых соединений и аммиака . Содержание кислорода составл ет не более. 0,001 об. % (10 ррт) , т. росы - 70°С.After purification, carbon monoxide contains almost no carbon dioxide, sulfur compounds and ammonia. The oxygen content is at most. 0,001 about. % (10 ppm), tons of dew - 70 ° С.
