E nwere ọtụtụ ụzọ isi hazie usoro dị iche iche maka nhazi gas eke ma ọ bụ ọgwụgwọ gas eke. Ihe ndị a bụ nhazi izugbe na nke a na-ahụkarị nke gas eke maka olulu gas na-abụghị nke ejikọtara ya. Ọ na-egosi otu esi ahazi gas eke a na-anaghị agwọ ọrịa ka ọ bụrụ gas eke maka ọrịre nke a na-ebuga na ahịa ndị ọrụ njedebe site na pipelines. Mmiri gas eke (NGL): propane, butane na C5+ (nke a bụ okwu a na-ejikarị eme ihe maka pentane na nnukwu hydrocarbon dị arọ molekul). A na-anakọta gas eke mbụ site na otu olulu mmiri dị nso ma buru ụzọ hazie ya na akpa nkewa na ebe a na-anakọta ya ruo wepụ mmiri mmiri n'efu (wepụ mmiri na gas eke) na gas eke. A na-ezigakarị mmiri condensate na ụlọ ọrụ mmepụta ihe, a na-emesokwa mmiri ahụ ma na-emeso ya dị ka mmiri mkpofu.
Mgbe ahụ, a na-ebuga gas nri gaa na ebe a na-agwọ gas site na paịpụ ahụ, ebe nhicha mbụ na-abụkarị iji wepụ gas asịd (hydrogen sulfide na carbon dioxide). N'ihi usoro arụmọrụ na mmachi gburugburu ebe obibi nke usoro amine, teknụzụ ọhụrụ dabere na ojiji nke akpụkpọ ahụ polymer iji kewaa carbon dioxide na hydrogen sulfide site na iyi gas eke enwetawo nnabata ka ukwuu. Akpụkpọ ahụ na-adọrọ adọrọ n'ihi na ọ naghị eri ihe ndị na-eme ka ihe dị nro. A na-ewepụ gas acid (ọ bụrụ na ọ dị) site na ọgwụgwọ membrane ma ọ bụ amine, wee ziga ya na ngalaba mgbake sulfur, nke na-agbanwe hydrogen sulfide na gas acid ka ọ bụrụ sulfur elemental ma ọ bụ sulfuric acid. N'ime usoro enwere ike iji maka mgbanwe ndị a, usoro Claus bụ usoro a maara nke ọma maka iweghachite sulfur elemental, ebe usoro kọntaktị ọdịnala na WSA (usoro sulfuric acid mmiri) bụ teknụzụ kachasị eji maka iweghachite sulfuric acid. Enwere ike ịgwọ obere gas acid site na ọkụ.
A na-akpọkarị gas fọdụrụnụ sitere na usoro Claus gas ọdụ, e mesịa a na-agwọ gas ahụ na ngalaba ọgwụgwọ gas ọdụ iji weghachite ihe fọdụrụnụ nke sọlfọ ma weghachite ya na ngalaba Claus. N'otu aka ahụ, enwere ọtụtụ usoro enwere ike iji gwọọ gas ọdụ nke unit Claus. N'ihi nke a, usoro WSA dịkwa mma nke ukwuu n'ihi na ọ nwere ike ịme ọgwụgwọ ọkụ onwe onye na gas ọdụ.
Nzọụkwụ ọzọ nke ụlọ ọrụ na-agwọ gas bụ iji ihe ndị na-emegharị emegharị n'ime mmiri triethylene glycol (TEG), nke a maara dị ka mmiri mmiri ethylene glycol, delicacent chloride desiccant, ma ọ bụ ngwaọrụ pressure swing adsorption (PSA) site na iji ihe siri ike na-eme ka mmiri dịghachi ndụ iji wepụ uzuoku mmiri na gas.
