Skid na ƙwanƙwaran ƙwayar ƙwayar cuta shine mabuɗin na'ura a cikin tsarkakewar iskar gas ko sanyaya iskar gas. Molecular sieve ne alkali karfe aluminosilicate crystal tare da tsarin tsarin da uniform microporous tsarin. Lokacin da iskar gas ɗin da ke ɗauke da alamar ruwa ta ratsa cikin gadon siliki na kwayoyin halitta a cikin zafin jiki, ana shayar da ruwa da mercaptan, don haka rage ruwa da abun ciki na mercaptan a cikin iskar gas ɗin, fahimtar manufar bushewa da desulfurization. tsarin adsorption na sieve kwayoyin yawanci ana aiwatar da shi a cikin ƙananan zafin jiki da matsa lamba, yayin da farfadowa na desorption ana aiwatar da shi a babban zafin jiki da ƙananan matsa lamba. A karkashin aikin babban zazzabi, mai tsabta da kuma rage matsin iska mai tsafta, kuma yana da ikon sake fasalin ruwa, yana ganin cigrovoration da aiwatar da tsari na kwayar cutar kwayar cuta.
Hanyar sieve na kwayoyin halitta wani nau'i ne na hanyar bushewa mai zurfi, wanda aka yi amfani dashi sau da yawa a cikin tsarin rabuwa da ƙananan zafin jiki, irin su farfadowa na gas condensate (NGL) da tsarin bushewa a cikin samar da iskar gas mai laushi (LNG). Bugu da kari, ana kuma amfani da dehydration na molecular sieve wajen samar da matsewar iskar gas na man mota.

Ana amfani da bushewar ƙwayar ƙwayar ƙwayar cuta gabaɗaya ga lokuta masu zuwa:
a. Inda ake buƙatar raɓa na iskar gas ya zama ƙasa da -40 ℃.
b. Ya dace da ma'aunin raɓa na hydrocarbon sarrafa iskar gas mai ƙarfi mai ƙarfi.
c. Gas na halitta yana bushewa kuma yana tsarkakewa a lokaci guda.
d. Lokacin da iskar gas mai ɗauke da H2S ya bushe kuma ya narkar da shi a cikin glycol, zai haifar da fitar da iskar gas mai sabuntawa.
e. Lokacin da LPG da NGL bushewa suna buƙatar cire sulfide alama (H2S, CO
COS, CS2, mercaptan) a lokaci guda.

Ana amfani da kafaifan tallan gado don rashin ruwa na kwayoyin halitta, don haka naúrar yakamata ya kasance yana da aƙalla adsorbers guda biyu, ɗaya a cikin matakin bushewar bushewa, ɗayan a cikin farfadowa da yanayin sanyaya. Lokacin da ƙarfin naúrar ya yi girma sosai, ana iya tsara tsarin hasumiya da yawa.
