I-alumina esebenzayo kunye nesihluzo semolekyuli, zifana (zombini ziza ngesimo esincinci esingqukuva esinamasongo), zenza inkqubo efanayo (zifunxa izinto kwinqanaba lemolekyuli), kwaye zombini zineempawu zokuvuselela (ungayisebenzisa kwakhona le nto xa i-desiccant ifikelele kumthamo wayo) kodwa ziimveliso ezimbini ezahlukeneyo ngokupheleleyo. Ngoko ke umbuzo ngulo, njengoko zifana kangaka, zahluke njani?
Oko zenziwe ngako yindawo elungileyo yokuqala. I-alumina esebenzayo yenziwe nge-aluminium oxide enemingxuma emininzi, ngelixa i-molecular seeve yenziwe nge-crystalline metal alumino-silicates. Oku kuthetha ukuba ii-pores kwi-molecular seeve zinokubunjwa zibe ziisayizi ezithile ezibonwa njenge-3A, 4A, 5A, kunye ne-13X, apho ii-pores ze-alumina ezisebenzayo zingenazo iisayizi ezithile ezilinganisiweyo. Oku kuthetha ukuba i-molecular seeve ingasetyenziselwa ukwahlula ii-molecule ezithile ezinobukhulu obuthile kwenye, umzekelo ukususa i-ammonia kwi-gas streams.
Ngokwembono yokusetyenziswa, nantsi indlela ezahluka ngayo. I-alumina esebenzayo inomthamo oqinileyo wokufunxa amanzi, inokufunxa amanzi amaninzi kunesihluzo semolekyuli, oku kuyenza ibe yinto eluncedo kakhulu kwi-air compressors okanye kwizicelo ezithile zokucubungula igesi yendalo. Ukuqina kwento kuyivumela ukuba imelane noxinzelelo olukhulu kunye namanqanaba aphezulu okufuma.
I-alumina esebenzayo ayinako ukufunxa uluhlu olubanzi lwezinto okanye yahlule iimolekyuli ezithile kwenye njengee-molecular seeves, nto leyo eyenza ukuba ingasebenzi kwinkqubo efana nokuphelelwa ngamanzi yi-ethanol. Oku kungenxa yokuba i-alumina esebenzayo iya kukwazi ukufunxa zombini iimolekyuli ze-ethanol kunye namanzi kwaye ngaloo ndlela akukho kwahlukana kuya kwenzeka.
Isihluzo semolekyuli sisenokungakwazi ukufunxa amanzi amaninzi kodwa ukuba ubufuna ukunciphisa amanzi ukuya kwi-0.1ppm, isihluzo semolekyuli siya kuba sisixhobo sakho sokufunxa kuba le yinto ezinye izihluzo ngaphandle kwesihluzo semolekyuli ezingakhange zikwazi ukuyenza.
Isihluzo seemolekyuli singasetyenziselwa ukwahlula iimolekyuli ezithile kwenye, ngenxa yokwenziwa ngokwezifiso kobukhulu beembobo zazo. Umzekelo, ungahlula amanzi kwi-ethanol, kunye ne-carbon dioxide, i-ammonia, kunye nee-hydrocarbons ezinkulu kwimithombo yegesi yendalo, into leyo i-alumina esebenzayo engenakuyenza, okanye engenakuyenza ngempumelelo efanayo.
