ОABOUT

Изобретение может быть использовано в химической промьгашенности, н пример в производстве синтетическог аммиака дл  очистки конвертированного газа. Известен способ очистки газа от двуокиси углерода путем химической абсорбции водными растворами апкано аминов, в частности моноэтаноламина Очистку ведут при температуре от 30 до и парциальном давлении двуокиси углерода менее 2 атм. Регенерацию абсорбента провод т при повышенных температурах. Дл  упрощени  технологической сх мы процесса в качестве хемосорбента используют аминопропионитрил формулы TiV т снгснгстт. где R и R алкильные водород или С,, дикалы С например диметиламинопропионитрил. Процесс регенерации можно вести при температуре абсорбции, кроме того , достичь высокой степени очистки при значительном удешевлении способа, так как нет необходимости использовать такие аппараты, как холодильник , теплообменник и кип тильник регенерированного раст- , вора. Пример. Газ, содержащий 24,4 СОг, 2,4% СО, 74,5% Н, 0,9% СН и 0,8% Nj, подают на абсорбцию диметиламинопропионитрилом . На выходе очищенный газ имеет состав: 2% СО, 3,1% СО, 92,8% Н2 и 1,1% СН4.The invention can be used in chemical industry, for example in the production of synthetic ammonia for the purification of converted gas. A known method of purifying gas from carbon dioxide by chemical absorption by aqueous solutions of appanes amines, in particular monoethanolamine. Purification is carried out at a temperature of from 30 to and a partial pressure of carbon dioxide less than 2 atm. Absorbent regeneration is carried out at elevated temperatures. To simplify the process, an aminopropionitrile of the formula TiV and Sngngst is used as a chemisorbent. where R and R are alkyl hydrogen or C ,, dicals With for example dimethylaminopropionitrile. The regeneration process can be carried out at the absorption temperature, in addition, a high degree of purification can be achieved with a significant reduction in the cost of the method, since there is no need to use devices such as a refrigerator, a heat exchanger, and a regenerated plant and thief boiler. Example. A gas containing 24.4 CO2, 2.4% CO, 74.5% H, 0.9% CH, and 0.8% Nj is fed to the absorption by dimethylaminopropionitrile. At the outlet, the purified gas has the composition: 2% CO, 3.1% CO, 92.8% H2, and 1.1% CH4.
