A na-ejikarị skid nke MDEA desulfurization maka gas eke eme ihe mgbe carbon sulfur nke gas nri dị oke elu, yana mgbe achọrọ iwepụ H2S nhọrọ iji nweta acid gas dabara adaba maka nhazi osisi Claus, yana ọnọdụ ndị ọzọ enwere ike ịhọrọ iji wepụ H2S; Mgbe ị na-ewepụ H2S ma wepụ nnukwu CO2, enwere ike iji MDEA na alcoholamine ndị ọzọ (dịka DEA) dị ka usoro amine agwakọtara;

Usoro

Mgbe ewepụrụ ihe ndị na-adịghị ọcha siri ike na mmiri mmiri site na gas nri site na ihe nkewa na ihe nzacha, a na-ewepụ gas nri ahụ na ụlọ elu valvụ float. A na-eji ihe ngwọta Methyl diethanol (MDEA) dị ka ihe na-eme ka mmiri dị ọcha n'ụlọ elu ahụ.

Mgbe ewepụrụ obere ụfụfụ mmiri MDEA site na gas ahụ site na ihe nkesa mmiri mmiri, gas eke mmiri mmiri na-abanye n'ụlọ elu mmiri mmiri.

A na-eji TEG eme ka mmiri ghara ịdị n'ime ụlọ elu ahụ, a na-ejikwa gas akọrọ sitere na ụlọ elu mmiri ghara ịdị n'ime ya. A na-eji gas nkịtị eme ihe dị ka gas ruru eru maka mbupụ.

A na-ekupụ mmiri mmiri bara ụba nke MDEA dị n'ụlọ elu desulfurization iji wepụ hydrocarbons ma jiri nzacha mee ka ọ dị ọcha. E mesịa, a na-ekpo ya ọkụ site na uzuoku iji mee ka mmiri MDEA na-adịghị mma dịghachi ọhụrụ, nke a na-awụnye na ụlọ elu desulfurization maka ịgbaze cyclic.

A na-eji ihe nkesa mmiri acid-water ewepụ gas sitere na mmiri mmiri MDEA bara ụba, a na-awụpụkwa mmiri MDEA kewapụrụ iche na ụlọ elu desulfurization. A na-ekpo ọkụ mmiri mmiri TEG bara ụba nke ejiri na ụlọ elu dehydration iji mee ka mmiri TEG dịghachi mma site na kọlụm distillation, tankị flash na nzacha. A na-awụpụ ya na ụlọ elu dehydration maka mmiri mmiri ozuzo.

Mgbe etinyere gas H2S n'ime tankị nchekwa gas acid n'ebe nkewa nke ihe nkesa mmiri acid ahụ, a na-ekpo ọkụ ya n'ime ọkụ mmeghachi omume ma na-emeghachi omume na ikuku nke ihe nrụpụta ikuku ahụ mịpụtara iji mepụta SO2, nke na-emeghachi omume na H2S fọdụrụ iji mepụta sọlfọ elemental, wee nweta sọlfọ mgbe ọ jụrụ oyi.
