Изобретеш - относитс -к-абевр§ц онной очистки газов от двуокиси .угле рода и может быть использовано в химической , нефтехимической, пищевой и других отрасл х промышленности.Invented - refers to the abnormal gas cleaning of dioxide from a carbon of the genus and can be used in the chemical, petrochemical, food and other industries.
.Известен способ очистки от двуокиси углерода путем абсорбции при повышенном давлении и десорбции двуокиси углерода из насыщенного абсорбента снижением давлени и тепломассообменом за счет подвода тепла извне . A known method for purifying carbon dioxide by absorption at elevated pressure and desorbing carbon dioxide from a saturated absorbent by reducing pressure and heat and mass transfer due to heat input from the outside.
Описанный способ характеризуетс тем, что десорбци двуокиси -углерода происходит при давлении, близком к атмосферному, что ограничивает степень выделени двуокиси углерода из насыщенного абсорбента и приводит к снижению степени очистки газа и к повышению расхода тепла.The described method is characterized by the fact that the desorption of carbon dioxide dioxide occurs at a pressure close to atmospheric, which limits the degree of carbon dioxide emission from the saturated absorbent and leads to a decrease in the degree of gas purification and to an increase in heat consumption.
Наиболее близким к изобретению по технической сущности и достигаемому результату вл етс способ очистки газа от двуокиси углерода путем аб . 2Closest to the invention to the technical essence and the achieved result is a method of cleaning gas from carbon dioxide by ab. 2
сорбции при давлении 15-100 ата и десорбции двуокиси углерода из насьщ(енного абсорбента редуцированием до 1-1,7 ата на первой ступени и вакуумированием на последуюпщх ступен х с отводом выде лившейс двуокиси углерода после каждой ступени 2. sorption at a pressure of 15–100 atm and desorption of carbon dioxide from the whole (as absorbed by reducing to 1–1.7 atm at the first stage and evacuating at the subsequent stages, with evacuated carbon dioxide after each stage 2.
Известный способ о.бладает тем существенньм недостатком, что не исполь зуетс энерги сжати газа, вьщел емого при десорбции, что приводит к увеличению знергозатрат.The known method makes it a significant disadvantage that it does not use the energy of compression of the gas, which is absorbed during desorption, which leads to an increase in energy consumption.
Цель изобретени - снижение энергозатрат .The purpose of the invention is to reduce energy consumption.
