Description

Изобретение относитс  к абсорбцио ной оггистке газов и может быть испол зовано в химической промьшшенности. например, в пооцессах моноэтаноламиновой о шстки газов от двуокиси угле . рода. Известен способ абсорбционной очистки газов, включающий абсорбцию газов оаствооом. предварительный наг рев насыщенного раствора регенериоованным оаствором и регенерапйю. При этом дл  нагрева насыщенного раствор используютс  громоздкие теплообменники . С Целью снижени  капитальных затрат и расхода энеогии, по предлагаемому способу нагоев насыщенного рАствоса осуществл ют при одновременной десорбции растворенного газа. Перед нагревом оаствор дросселируют . Если жидкость нагреваетс  с одновременным изменением ее состава (за счет десорбции газа) ПРИ одинаковом количестве тепла, переданного ей от регенерированного раствора, она нагреваетс  до более низкой температуры, следовательно, движуща  сила теплообмена на гор чем конпе теплообменника будет больше. Это объ сн етс  тем, что ПРИ десорбции растворенных газов теапосодержание нагреваемой жидкости измен етс  сильнее, чем при посто нном составе. В итоге увеличиваетс  средн   логарифмическа  разность температур при посто нной или меньшей разности температур на холодном конце теплообменника. Это позвол ет вести процесс при значительно меньших поверхност х теплообменника и меньшем расходе энергии. На чертеже приведена схема, по сн юща  предлагаемый способ. Газ по линии 1 с концентрацией COg 20% поступает в абсорбционную колонну 2. Очищенный газ отвод т по линии 3. Абсорбцию ведут ПРИ давлении 30 атм 20%-ным раствором моноэтаноламина ( МЭА ), содержащемThe invention relates to the absorption of gas trap and can be used in chemical industry. for example, in monoethanolamine processes for carbon dioxide carbon dioxide. kind of. There is a method of absorption gas purification, including the absorption of gases ostvoj. preliminary heating of a saturated solution with a regenerated solution and regeneration. At the same time, bulky heat exchangers are used to heat the saturated solution. With the aim of reducing capital costs and energy consumption, according to the proposed method, the nagoi saturated solution is carried out with simultaneous desorption of the dissolved gas. Before heating, the solution is throttled. If the liquid is heated with a simultaneous change in its composition (due to gas desorption) with the same amount of heat transferred from the regenerated solution to it, it is heated to a lower temperature, therefore, the driving force of heat exchange on the heat exchanger will be greater. This is due to the fact that, when the dissolved gases are desorbed, the content of the heated liquid changes more than at a constant composition. As a result, the average logarithmic temperature difference increases with a constant or smaller temperature difference at the cold end of the heat exchanger. This allows the process to be carried out with significantly smaller heat exchanger surfaces and less energy consumption. The drawing is a diagram explaining the proposed method. Gas through line 1 with a COg concentration of 20% enters the absorption column 2. The purified gas is withdrawn through line 3. The absorption is carried out at a pressure of 30 atm. With a 20% solution of monoethanolamine (MEA) containing
