Decarburization na iskar gas (decarbonization) skid, shine na'ura mai mahimmanci a cikin tsarkakewa ko magani.

Abubuwan da ke cikin carbon dioxide a daidaitaccen ingancin iskar gas bai kamata ya wuce 3%. Kuma carbon dioxide a cikin ruwa bayan karfe yana da karfi mai lalata. Idan darajar PH iri ɗaya ce, rabon acidity na carbon dioxide shima ya fi girma, don haka matakin lalata carbon dioxide akan ƙarfe shima ya fi girma.

Matsa lamba adsorption (PSA) sabuwar fasaha ce da ake amfani da ita don raba cakuda gas a cikin fasahar rabuwa ta adsorption. Idan aka kwatanta da hanyar shan sinadarai na gargajiya, fasahar PSA tana da kyau ta fuskar tattalin arziki don cirewa da dawo da H2S da CO2 daga iskar gas, kuma ana haɓakawa sosai.

Fasahar rabuwar gas na PSA yana da fa'ida na aiki mai sauƙi, ƙarancin matsa lamba, rashin ruwa yayin cire CO2, ƙarancin raɓa na iskar gas da ruwa mai tsafta, kuma samfuran na iya biyan buƙatun fitar da iskar gas. Ana iya amfani da PSA don tattarawar CO2 da zaɓin desulfurization a cikin iskar gas.
