Tsarin Tsabtace Gas Na Halitta Kwayoyin Sive Desulphurization

Tare da ci gaban al'ummarmu, muna ba da shawarar makamashi mai tsabta, don haka buƙatar iskar gas a matsayin makamashi mai tsabta yana karuwa. To sai dai kuma, a yayin da ake yin amfani da iskar gas, yawancin rijiyoyin iskar gas kan kunshi sinadarin hydrogen sulfide, wanda zai haifar da gurbatar kayan aiki da bututun mai, da gurbata muhalli da kuma yin barazana ga lafiyar dan Adam. Tare da ci gaban kimiyya da fasaha, yawan amfani da fasaha na lalata iskar gas ya warware waɗannan matsalolin, amma a lokaci guda, farashin tsabtace iskar gas da magani ya karu daidai da haka.

Ƙwaƙwalwar ƙwayar ƙwayar cuta (wanda kuma ake kira desulfurization) skid, wanda kuma ake kira molecular sieve sweeting skid, shine maɓalli na na'ura a cikin tsarkakewar iskar gas ko aikin kwantar da iskar gas.

Molecular sieve ne alkali karfe aluminosilicate crystal tare da kwarangwal tsarin da uniform microporous tsarin. Yana da adsorbent tare da kyakkyawan aiki, babban ƙarfin talla da zaɓin talla. Da fari dai, akwai tashoshi masu yawa tare da girman pore iri ɗaya da ramukan da aka tsara daidai a cikin tsarin sieve na ƙwayoyin cuta, wanda ba wai kawai yana ba da babban yanki mai girma ba, har ma yana iyakance shigarwar ƙwayoyin da suka fi girma fiye da ramuka; Abu na biyu, saman sieve na kwayoyin yana da babban polarity saboda halayen lattice na ionic, don haka yana da babban ƙarfin adsorption don ƙwayoyin da ba su da yawa, ƙwayoyin polar da ƙwayoyin polarizable. Ruwa da hydrogen sulfide molecules ne na igiya, kuma diamita na kwayoyin ya yi ƙasa da diamita na ramukan ramin kwayoyin halitta. Lokacin da danyen gas ɗin da ke ɗauke da alamar ruwa ya ratsa ta cikin gadon siliki na kwayoyin a yanayin zafin jiki, ana shayar da ruwa da hydrogen sulfide, Don haka, abun ciki na ruwa da hydrogen sulfide a cikin iskar gas yana raguwa, kuma manufar bushewa da desulfurization ya cika. Tsarin adsorption na sieve na kwayoyin halitta ya haɗa da ƙaddamarwar capillary da haɓakar jiki ta hanyar van der Waals karfi .A cewar Kelvin equation, capillary condensation yana raguwa tare da karuwar yawan zafin jiki, yayin da adsorption na jiki shine tsarin exothermic, kuma adsorption yana raguwa tare da karuwar yawan zafin jiki. kuma yana ƙaruwa tare da karuwar matsa lamba; Sabili da haka, tsarin adsorption na sieve kwayoyin yawanci ana aiwatar da shi a cikin ƙananan zafin jiki da matsa lamba, yayin da farfadowar nazari ana aiwatar da shi a babban zafin jiki da rage matsa lamba.
