Ngwaahịa nke ngalaba desulfurization nke alaka ụlọ ọrụ mmanụ PetroChina Changqing dị n'ụlọ ọrụ anyị

Ngalaba desulfurization nke PetroChina Changqing oilfield Branch nwere ikike nhazi nke 40000 Nm3 na 1.0 MPa.

Mkpuchi desulfurization nke MDEA n'ihi na a na-anabata gas eke mgbe niile mgbe carbon sulfur nke gas nri dị oke elu, yana mgbe a na-ewepụ H na nhọrọ.₂A chọrọ S iji nweta acid gas nke dabara adaba maka nhazi osisi Claus, yana ọnọdụ ndị ọzọ enwere ike ịhọrọ iji wepụ H₂S; Mgbe ị na-ewepụ H₂S na iwepụ nnukwu CO₂, enwere ike iji MDEA na alcoholamine ndị ọzọ (dịka DEA) mee ihe dị ka usoro amine agwakọtara;

Usoro nke Mkpụcha mwepụ gas acid nke MDEAbụ:

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 mmiri. A na-eji ngwọta MDEA eme ihe dị ka ihe na-eme ka mmiri ghara ịdị 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 H n'ime ọgwụ₂S gas 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 compressor ikuku mịpụtara iji mepụta SO₂, nke na-emeghachi omume na H fọdụrụnụ₂S iji mepụta sọlfọ elemental, wee nweta sọlfọ mgbe ọ jụrụ oyi.

Gas eke mgbe e mechara desulfurization ga-abanye n'ime ihe na-ebelata okpomọkụ na gas wee buru ya gaa na ụlọ ọrụ jenereta site na paịpụ.
