Mfundo yofunika

Molecular sieve desulphurization (desulfurization) skid, yomwe imatchedwanso molecular sieve sweeting skid, ndi chipangizo chofunikira kwambiri pakuyeretsa gasi kapena kukonza mpweya wachilengedwe. Sieve ya maselo ndi alkali chitsulo aluminosilicate krustalo ndi chimango dongosolo ndi yunifolomu microporous kapangidwe. Pamene mpweya wodyetsa womwe uli ndi madzi otsatizana umadutsa pa bedi la sieve ya maselo kutentha kwa firiji, madzi otsatiridwa ndi mercaptan amatengedwa, motero kuchepetsa madzi ndi mercaptan zomwe zili mu gasi wodyetsa, kuzindikira cholinga cha kutaya madzi m'thupi ndi desulfurization. Njira yotsatsira ma molekyulu sieve imaphatikizapo kukomoka kwa capillary ndi kutsatsa kwakuthupi komwe kumayambitsidwa ndi mphamvu ya van der Waals. Kuchokera ku Kelvin equation, zikhoza kuwoneka kuti capillary condensation imafooketsa ndi kuwonjezeka kwa kutentha, pamene kutengeka kwa thupi ndi njira yowonongeka, ndipo kutsekemera kwake kumafooketsa ndi kuwonjezeka kwa kutentha ndikuwonjezeka ndi kuwonjezeka kwa kuthamanga; Chifukwa chake, njira ya adsorption ya sieve ya molekyulu nthawi zambiri imachitika pa kutentha kochepa komanso kuthamanga kwambiri, pomwe kusinthika kwa desorption kumachitika pa kutentha kwakukulu komanso kutsika. Pansi pa kutentha kwakukulu, mpweya woyeretsa komanso wochepetsetsa wotsitsimutsa, molecular sieve adsorbent imatulutsa adsorbate mu micropore mu mpweya wotsitsimutsa mpaka kuchuluka kwa adsorbate mu adsorbent kufika pamlingo wochepa kwambiri, ndipo amatha kuyamwa madzi ndi mercaptan kuchokera ku gasi wodyetsa, pozindikira kusinthika kwa maselo ndi kubwezeretsanso ndondomeko ya sieve.

Njira zamakono

Mayendedwe a gasi achilengedwe sieve desulphurization (desulfurization) skid akuwonetsedwa pachithunzichi. Chigawochi chimagwiritsa ntchito njira zitatu za nsanja, kutsatsa kwa nsanja imodzi, kukonzanso nsanja imodzi ndi kuzizira kwa nsanja imodzi. Pambuyo kuchotsa intrained hydrocarbon madzi kudzera chakudya mpweya fyuluta olekanitsa, chakudya mpweya amalowa mu molecular sieve desulfurization nsanja. Madzi ndi mercaptan mu gasi wa chakudya amatsatiridwa ndi sieve ya molekyulu kuti azindikire kuchepa kwa madzi m'thupi ndi njira ya mercaptan adsorption. Mpweya woyeretsedwa kuchokera ku kutaya madzi m'thupi ndi kuchotsedwa kwa mercaptan umalowa muzosefera za fumbi lamafuta kuti achotse fumbi la sieve ya maselo, kenako amatumizidwa kunja ngati mpweya wamafuta.

Masieve a mamolekyu amafunika kupangidwanso pambuyo potsatsa madzi ena ndi mercaptan. Pambuyo posefa fumbi lamafuta amafuta, gawo lina lamafuta limachotsedwa ngati mpweya wosinthika. Gasi atatenthedwa mpaka 300 ℃ ndi ng'anjo yotenthetsera, nsanjayo imatenthedwa pang'onopang'ono mpaka 272 ℃ kudzera mu nsanja ya molecular sieve desulfurization yomwe yamaliza ntchito yotsatsa kuchokera pansi kupita pamwamba, kuti madzi ndi mercaptan adsorbed pa sieve ya maselo amatha kupatulidwanso kuti athetseretu njira yowonjezeretsa.
