Babban Ingantacciyar Jiyya na Gas ɗin Gas na China Masu Fitar da Gas - Molecular sieve desulphurization skid - Rongteng

Ka'ida

Molecular sieve desulphurization (desulfurization) skid, wanda kuma ake kira kwayoyin sieve sweeting skid, 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 halitta ya haɗa da haɓakar capillary condensation da adsorption na jiki wanda van der Waals ƙarfi ya haifar. Daga ma'auni na Kelvin, ana iya ganin cewa ƙwayar capillary yana raunana tare da karuwar yawan zafin jiki, yayin da ƙwayar jiki ta jiki shine tsari na exothermic, kuma ƙaddamar da shi yana raunana tare da karuwar zafin jiki kuma yana ƙaruwa tare da karuwar matsa lamba; sabili da haka, tsarin adsorption na sieve kwayoyin yawanci ana yin su ne a 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.

Tsarin fasaha

Ana nuna tsarin tafiyar da iskar gas na kwayoyin sieve desulphurization (desulfurization) skid a cikin zane. Naúrar tana ɗaukar tsarin hasumiya uku, tallan hasumiya ɗaya, sabunta hasumiya ɗaya da sanyaya hasumiya ɗaya. Bayan cire entrained hydrocarbon ruwa ta hanyar feed gas tace SEPARATOR, da feed gas shiga kwayoyin sieve desulfurization hasumiya. Ruwan da mercaptan a cikin iskar gas ɗin ana haɗa su ta hanyar sieve na kwayoyin don gane rashin ruwa da tsarin tallan mercaptan. Gas ɗin da aka tsarkake daga bushewa da cirewar mercaptan yana shiga cikin samfurin ƙurar ƙurar gas don cire ƙurar sieve na ƙwayoyin cuta, sannan ana fitar dashi azaman iskar gas.

Ana buƙatar sake haifar da sieves na ƙwayoyin cuta bayan an haɗa wani adadin ruwa da mercaptan. Bayan tace ƙurar gas ɗin samfurin, ana fitar da wani ɓangare na iskar gas azaman iskar gas mai sabuntawa. Bayan gas ne mai tsanani zuwa 300 ℃ da dumama makera, da hasumiya ne sannu a hankali mai tsanani zuwa 272 ℃ ta kwayoyin sieve desulfurization hasumiya wanda ya kammala adsorption tsari daga kasa zuwa sama, sabõda haka, da ruwa da mercaptan adsorbed a kan kwayoyin sieve za a iya rabu da kuma zama wadatacce farfadowa da iskar gas don kammala aikin.
