Description

Дл  ОЧИСТКИ газов от сероводорода обычно примен ют абсорбцию его водными растворами абсорбента (фенол та натри , трикалийфосфата , триэтаноламина и др.) с последующей регенерацией абсорбента , вновь направл емого на абсорбцию сероводорода. ,For CLEANING gases from hydrogen sulfide, absorption by aqueous solutions of an absorbent (sodium phenol, tripotassium phosphate, triethanolamine, etc.) is usually used, followed by regeneration of the absorbent re-directed to absorption of hydrogen sulfide. ,

Предлагаетс  способ очистки естественных , крекинговых и подобных газов от сероводорода (и других примесей) путем абсорбции и последующей десорбции в две фа-, зы с использованием парогазовой смеси второй фазы в качестве греющего агента в первой фазе десорбции .A method is proposed for purifying natural, cracking and similar gases from hydrogen sulfide (and other impurities) by absorption and subsequent desorption into two phases, using a second-phase vapor-gas mixture as a heating agent in the first desorption phase.

Абсорбент, частично регенерирор .анньш в верхней части десорбера /, перетекает через трубку 2 в 1;ИЖН1Ою часть десорбера 5 и полностью или частично может оыть направлен на нижние тарелки абсорбера 4. Смесь паров абсорбированного компонента и абсорбента по трубе 5 из нижней части десорбера направл етс  на обогрев верхней части десорбера. Здесь пары абсорбента конденсируютс , отдава  теплоту парообразовани  на обогрев раствора (вместо расхода свежегоAbsorbent, partially regenerated. An anchoring in the upper part of the desorber / flows through a 2 in 1 pipe; IZHN1Ov part of the desorber 5 and can be fully or partially directed to the lower plates of the absorber 4. It is used for heating the upper part of the stripper. Here, the absorbent vapors are condensed, giving away the heat of vaporization to heat the solution (instead of the consumption of fresh

пара), и в виде флегмы стекают обратно . Десорбированный в нижней части десорбера газ отводитс  из нагревательных элементов и присоедин етс  к газу из парциального конденсатора 6.couple), and in the form of phlegm flow back. The gas stripped at the bottom of the stripper is discharged from the heating elements and connected to the gas from the partial condenser 6.

В остальном схема аналогична производственным схемам одноступенчатой десорбции.The rest of the scheme is similar to the production schemes of single-stage desorption.

Так как раствор, перетекающий из верхней части десорбера в нижнюю , беднее сероводородом, чем раствор, вход щий в десорбер сверху , то равновесие в газопаровой фазе, выдел ющейс  из раствора, во второй ступени десорбера относительно сдвинуто в сторону вод ного пара. Например, при половине выдел емого в нижней части сероводорода , здесь на 1 моль его выдел етс  10 молей вод ного пара , в то врем  как наверху регенератора это отношение равно 2,2. Это обсто тельство служит дл  повышени  эффективности способа к обуслов.швает возг ;ожность эконо ии пара.Since the solution flowing from the top of the stripper to the bottom is poorer than hydrogen sulfide than the solution entering the stripper from above, the equilibrium in the gas-vapor phase released from the solution in the second stage of the stripper is relatively shifted towards water vapor. For example, with half of the hydrogen sulfide released in the lower part, 10 moles of water vapor are released per mole of it, while at the top of the regenerator, this ratio is 2.2. This circumstance serves to increase the efficiency of the method, which makes it possible to save steam.

Дл  получени  необходимой разности температур между газо-паровой фазой из второй ступени десорбера и раствором в первой ступени.To obtain the required temperature difference between the gas-vapor phase from the second stage of the stripper and the solution in the first stage.

нижн   часть должна работать под давлением и раствор в нее подаватьс  насосом. Дл  наличи  вышеуказанной разности температур в {2,5° и нри наличии наверху десорбера 0,05 ата, давление в нижней части его должно быть около 2 ата.the lower part should work under pressure and the solution should be pumped into it. In order to have the above temperature difference in {2.5 ° and if there is 0.05 atm at the top of the desorber, its pressure in the lower part should be about 2 at.
