Pali njira zambiri zokhazikitsira njira zosiyanasiyana zopangira gasi kapena kukonza gasi. Zotsatirazi ndizomwe zimapangidwira komanso momwe gasi wachilengedwe amapangidwira pazitsime zosagwirizana ndi gasi. Ikuwonetsa momwe gasi wosasinthidwa amasinthidwa kukhala gasi wogulitsidwa omwe amatumizidwa kumsika wa ogwiritsa ntchito kumapeto kudzera pa mapaipi.Natural gas liquid (NGL): propane, butane ndi C5+(awa ndi mawu odziwika bwino a pentane kuphatikiza high molecular weight hydrocarbon ). Mpweya woyambirira wachilengedwe nthawi zambiri umatengedwa kuchokera ku zitsime zoyandikana ndikuyamba kukonzedwa mu chidebe cholekanitsa pamalo otolera.chotsani madzi amadzimadzi aulere (chotsani madzi ku gasi) ndi mpweya wachilengedwe. Madzi a condensate nthawi zambiri amatumizidwa kumalo oyeretsera, ndipo madziwo amawathira ngati madzi oipa.
Kenako, gasi wodyetserako amatumizidwa kumalo opangira mafuta kudzera papaipi, komwe kuyeretsedwa koyamba kumakhalakuchotsa mpweya wa asidi (hydrogen sulfide ndi carbon dioxide) .Chifukwa cha mndandanda wa ntchito ndi malire a chilengedwe cha ndondomeko ya amine, matekinoloje atsopano okhudzana ndi kugwiritsa ntchito ma polima kuti alekanitse carbon dioxide ndi hydrogen sulfide kuchokera ku mitsinje ya gasi yakhala ikuvomerezedwa kwambiri. Nembanemba ndi wokongola chifukwa sadya reagents.Acid mpweya (ngati alipo) kuchotsedwa nembanemba kapena mankhwala amine, ndiyeno kutumizidwa sulfure kuchira unit, amene otembenuka wa hydrogen sulfide mu asidi mpweya mu elemental sulfure kapena asidi sulfure. Mwa njira zomwe zingagwiritsidwe ntchito potembenuza, njira ya Claus ndiyo njira yodziwika kwambiri yobwezeretsa sulfure, pomwe njira zachikhalidwe zolumikizirana ndi WSA (njira yonyowa ya sulfuric acid) ndi njira zomwe zimagwiritsidwa ntchito kwambiri pobwezeretsa sulfuric acid. Kagasi kakang'ono ka asidi amatha kuthandizidwa ndi kuyaka.
Gasi wotsalira kuchokera ku ndondomeko ya Claus nthawi zambiri amatchedwa gasi wa mchira, ndiyeno gasiyo amawathira mu gasi wa mchira kuti atengerenso sulfure yotsalayo ndikubwezeretsanso ku Claus unit. Mofananamo, pali njira zambiri zomwe zingagwiritsidwe ntchito pochiza mpweya wa mchira wa unit Claus. Pazifukwa izi, njira ya WSA ndiyabwinonso chifukwa imatha kudzipangira moto wodzitenthetsera pa gasi la mchira.
Chotsatira chotsatira cha makina opangira gasi ndikugwiritsa ntchito njira yowonjezera yowonjezera mumadzimadzi a triethylene glycol (TEG), omwe amadziwika kuti ethylene glycol dehydration, deliquescent chloride desiccant, kapena pressure swing adsorption (PSA) chipangizo pogwiritsa ntchito adsorbent yolimba kuti adsorption ya madzi ongowonjezwdwa kuchotsa. mpweya wochokera ku gasi. Njira zina zatsopano, monga kupatukana kwa membrane, zitha kuganiziridwanso.
Mercury imachotsedwa pogwiritsa ntchito njira yotsatsira monga activated carbon kapena renewable molecular sieve.
Ngakhale sizodziwika, nthawi zina imodzi mwa njira zitatu imagwiritsidwa ntchito kuchotsa ndi kukana nayitrogeni:
- Njira yochepetsera kutentha (chipangizo chochotsa nayitrogeni ) amagwiritsa ntchito distillation yotsika kutentha. Ngati ndi kotheka, ndondomeko akhoza kusinthidwa kuti achire helium.
- Pamayamwidwe, mafuta owonda kapena zosungunulira zapadera zimagwiritsidwa ntchito ngati zotsekemera.
- Njira yotsatsira imagwiritsa ntchito sieve ya kaboni kapena molekyulu ngati adsorbent. Kugwiritsa ntchito njirayi kungakhale kochepa chifukwa akuti kumayambitsa kutaya kwa butane ndi ma hydrocarbon olemera kwambiri.
