Kune nzira dzakawanda dzekugadzirisa maitiro akasiyana-siyana ekugadzirisa gasi rechisikigo kana kugadzirisa gasi rechisikigo. Izvi zvinotevera chimiro chakajairika uye chakajairika chegasi rechisikigo rematsime egasi asina hukama. Izvi zvinoratidza kuti gasi rechisikigo risina kugadziriswa rinogadziriswa sei kuita gasi rechisikigo kuti ritengeswe iro rinotakurwa kuenda kumusika wevashandisi vekupedzisira kuburikidza nemapaipi. Gasi rechisikigo (NGL): propane, butane uye C5+ (iri izwi rinowanzo shandiswa kureva pentane pamwe nehydrocarbon ine huremu hwakawanda). Gasi rechisikigo rekutanga rinowanzo unganidzwa kubva muboka rematsime ari pedyo uye rinotanga kugadzirwa mumudziyo wekuparadzanisa panzvimbo yekuunganidzira kusvika bvisa mvura yemvura isina mvura (bvisa mvura kubva mugasi rechisikigo) uye gasi rechisikigo rakasanganiswa nemvura. Mvura yakasanganiswa nemvura inowanzoendeswa kunzvimbo yekucheneserwa mvura, uye mvura yacho inobatwa uye inobatwa semvura yakaraswa.
Zvadaro, gasi rinoiswa mufiriji rinoendeswa kufekitari yekurapa gasi kuburikidza nepombi, uko kucheneswa kwekutanga kunowanzoitwa kuti bvisa magasi ane acid (hydrogen sulfide necarbon dioxide). Nekuda kwekushanda kwakawanda uye miganhu yemaitiro eamine, matekinoroji matsva akavakirwa pakushandiswa kwema polymer membranes kuparadzanisa carbon dioxide nehydrogen sulfide kubva munzizi dzegasi rechisikigo akagamuchirwa zvakanyanya. Kamudzira kanoyevedza nekuti hakashandise ma reagents. Gasi reacid (kana riripo) rinobviswa ne membrane kana amine treatment, rozotumirwa ku unit yekudzoreredza sulfur, iyo inoshandura hydrogen sulfide mugasi reacid kuita elemental sulfur kana sulfuric acid. Pakati pemaitiro anogona kushandiswa pakushandura uku, Claus process ndiyo nzira inozivikanwa zvikuru yekudzoreredza elemental sulfur, nepo nzira yechinyakare yekubata uye WSA (wet sulfuric acid process) ndiyo matekinoroji anoshandiswa zvakanyanya ekudzoreredza sulfuric acid. Huwandu hushoma hwegasi reacid hunogona kurapwa nekupisa.
Gasi rinosara kubva kuClaus process rinowanzonzi tail gas, uye gasi rinozorapwa mu tail gas treatment unit kuti ridzore residual salfa compound uye ridzoserwe kuClaus unit. Saizvozvowo, kune maitiro akawanda anogona kushandiswa kurapa tail gas yeClaus unit. Nekuda kweizvi, WSA process yakakodzerawo nekuti inogona kuzvidziisa yega pa tail gas.
Danho rinotevera rekugadzira gasi nderekushandisa mvura inonyungudika mu triethylene glycol (TEG), inozivikanwa se ethylene glycol dehydration, deliquescent chloride desiccant, kana pressure swing adsorption (PSA) device uchishandisa solid adsorbent yekuwedzera mvura kuti ibvise mvura kubva mugasi. Mamwe maitiro matsva, akadai sekupatsanurwa kwemembrane, anogonawo kufungwa nezvawo.
Mercury inozobviswa uchishandisa nzira yekunyungudutsa mvura yakaita seyakagadziriswa kabhoni kana kuti inogadziriswazve.
Kunyangwe zvisingawanzoitiki, dzimwe nguva imwe yenzira nhatu dzinoshandiswa kubvisa nekuramba nitrogen:
- Maitiro ekupisa kwakaderera (mudziyo wekubvisa nitrogen) inoshandisa distillation inodziya zvishoma. Kana zvichidikanwa, maitiro acho anogona kuchinjwa kuti awane helium.
- Mukuita kwekunyudza, mafuta asina mafuta kana solvent chaiyo inoshandiswa senzira yekunyudza.
- Maitiro ekunyudza anoshandisa activated carbon kana molecular sieve se absorbent. Kushanda kwenzira iyi kunogona kunge kushoma nekuti inonzi inokonzera kurasikirwa kwebutane nemahydrocarbon anorema.
