Usoro nhazi gas eke maka iwepụ mmiri na acid gas
Nhazi gas sitere n'okike bụ usoro iwepụ uzuoku mmiri, hydrogen sulfide, mercaptan, na carbon dioxide site na gas sitere n'okike. Ngwa ndị bụ isi gụnyere ihe mgbochi ịkpọ nkụ mmiri, unit desulfurization, Ngalaba decarbonization, na mgbake hydrocarbon dị mfe otu.
Mmiri ịkpọ nkụ
Usoro ndị a na-ejikarị eme ihe maka mmiri gas sitere n'okike gụnyere obere okpomọkụ, ịmịkọrọ ihe siri ike, ịmịkọrọ mmiri mmiri, na usoro kemịkalụ reagent.
Usoro myọ molekụla bụ usoro mmiri mmiri miri emi a na-ejikarị eme ihe n'usoro nkewa mmiri mmiri dị ala, dịka mgbake gas condensate (NGL) na usoro mmiri mmiri n'imepụta gas mmiri mmiri (LNG). Na mgbakwunye, mmiri mmiri sieve dịkwa mkpa maka mmepụta gas agbakọrọ agbakọ nke ejiri dị ka mmanụ ụgbọala.
Ihe Usoro mmịkpọ mmiri nke TEG ọ dabara adaba maka nkụchi gas sitere n'okike yana oke mmiri na-eruba na oke mkpa maka mbelata ebe mmiri na-eruba.
Mwepụ CO2
E nwere ụzọ abụọ isi e si ewepụ CO2 na gas eke: usoro mmịpụta ihe mgbaze na usoro mmịpụta.
Ihe a na-ejikarị eme ihe maka usoro mmịpụta ihe mgbaze bụ ngwọta MDEA, usoro ahụ bụkwa ụlọ elu mmịpụta na ụlọ elu mmụgharị.
Mmezi PSA bụ ụdị usoro adsorption, nke dabere na teknụzụ adsorption swing pressure, nke na-eme ka gas kewaa ma sachaa site na ịgbanwe ọnọdụ nrụgide mgbe niile.
Mwepụ ihe mkpofu
E nwere ụzọ abụọ isi nke iwepụ ihe ndị sitere n'okike site na gas: iwepụ ihe ndị a kpọrọ nkụ na iwepụ ihe ndị a na-akpọ mmiri.
Ihe usoro amine Ọ dị mkpa mgbe gas sitere n'okike nwere obere H2S na oke CO2/H2S dị elu, mana ọdịnaya CO2 adịghị oke elu ma ọ chọghị iwepụ CO2 miri emi. Ụzọ a nwere ike iwepụ H2S na CO2 nke ọma n'otu oge.
A na-ejikarị usoro sieve molekụla eme ihe maka ngwa ndị chọrọ oke izi ezi nke desulfurization ma ọ bụ obere ọnụego mmiri.
Ihe Usoro LO-CAT na-eji mmiri mmiri nke mejupụtara sulfates, iron dị mgbagwoju anya, ihe mgbakwunye (surfactants, defoamers, na fungicides) maka iwepụ sulfurization. Usoro Lo-Cat dabara adaba maka ọgwụgwọ gas acid nke e kewara site na usoro kemịkalụ ma ọ bụ nke anụ ahụ. N'ihi oke nhazi ya, nnukwu mgbanwe ọrụ, nnukwu nhọrọ, na ịdị mma gburugburu ebe obibi, ọ ghọwo teknụzụ kachasị mma maka usoro mgbake sulfur obere.
Mwepụ nke Mercaptan
Mwepụ gas sitere n'okike na-ejikarị usoro sulfinol na usoro hydrodesulfurization maka iwepụ mercaptan.
Usoro sulfinol nwere uru dị na obere oriri ike, iwepụ sọlfọ organic, nnukwu ikike nhazi nke akụrụngwa, obere nchara, obere ụfụfụ, na mmebi nke ihe mgbaze ọkụ. Ọ dabara nke ọma karịsịa mgbe nrụgide akụkụ nke gas acidic dị na gas nri dị elu. Usoro a enweghị ike ime ka ọ dị ọcha nke ukwuu, a na-ejikarị ya ewepụ sọlfọ dị nro. Ọ dị mkpa iji ya na ụzọ ndị ọzọ.
Usoro mwepụ hydrodesulfurization mercaptan na-ebu ụzọ gbanwee sọlfọ organic ka ọ bụrụ sọlfọ na-adịghị ahụkebe, wee kewaa sọlfọ na-adịghị ahụkebe site na iji usoro adsorption.
