Alumina nesefa yemamorekuru dzakashanda, zvakafanana (zvose zvinouya muchimiro chidiki chakaita sedenderedzwa), zvinoita maitiro akafanana (zvinosveta zvinhu padanho remamorekuru), uye zvese zvine hunhu hwekudzoreredza (unogona kushandisazve zvinhu kana desiccant yasvika pakukwana) asi zvinhu zviviri zvakasiyana zvachose. Saka mubvunzo ndewokuti, nekufanana kwakawanda, zvakasiyana sei?
Zvavakagadzirwa nazvo inzvimbo yakanaka yekutanga. Alumina yakakamurwa inogadzirwa nealuminium oxide ine maburi akawanda, nepo molecular sieve inogadzirwa necrystalline metal alumino-silicates. Izvi zvinoreva kuti maburi ari pamolecular sieve anogona kuumbwa kuita saizi dzakatarwa dzinoonekwa se3A, 4A, 5A, uye 13X, uko maburi ealumina akakamurwa asina saizi dzakatarwa dzakatarwa. Izvi zvinoreva kuti molecular sieve inogona kushandiswa kuparadzanisa mamwe mamorekuru ane saizi dzakatarwa kubva kune mumwe nemumwe, semuenzaniso kubvisa ammonia kubva munzizi dzegasi rechisikigo.
Kubva pakushandiswa, heino kusiyana kwazvinoita. Alumina yakabatidzwa ine simba guru rekunyudza mvura, inogona kunyudza mvura yakawanda kupfuura molecular sefa, izvi zvinoita kuti ive chinhu chinobatsira zvikuru mumacompressor emhepo kana kune mamwe mashandisirwo ekugadzirisa gasi rechisikigo. Kugara kwenguva refu kwechinhu ichi kunoita kuti ikwanise kutsungirira kumanikidzwa kwakawanda pamwe chete nehunyoro hwakawanda.
Alumina yakabatidzwa haigone kunyudza zvinhu zvakasiyana-siyana kana kuparadzanisa mamwe mamorekuru kubva kune mumwe nemumwe sezvinoita mamorekuru ekusefa, zvichiita kuti isashande mukuita sekunge ethanol dehydration. Izvi zvinodaro nekuti alumina yakabatidzwa inogona kunyudza ese mamorekuru eethanol neemvura saka hapana kupatsanurwa kwaizoitika.
Sefa yemamorekuru ingasakwanisa kunwisa mvura yakawanda asi kana uchida kuderedza mvura kusvika pahuwandu hushoma, kusvika pa 0.1ppm, sefa yemamorekuru ndiyo yaungasarudza nekuti ichi chimwe chinhu chisina kukwanisa kuitwa nemamwe ma sefa kunze kwesefa yemamorekuru.
Sefa yemamorekuru inogona kushandiswawo kupatsanura mamorekuru chaiwo kubva kune mumwe nemumwe, nekuda kwekugadzirisa saizi yemaburi awo. Semuenzaniso unogona kupatsanura mvura kubva kuethanol, uye carbon dioxide, ammonia, uye mahydrocarbon makuru kubva kumvura dzegasi rechisikigo, izvo zvinhu izvo alumina inoshanda isingakwanise kuita, kana kuti isingakwanise kuita nekushanda kwakafanana.
