Ukufunxwa kwamanzi nge-molecular sieve kuxhomekeke kumxholo wamanzi wemveliso, izikhokelo zokususa amanzi ze-molecular sieve.
1. Ukusetyenziswa: I-4A i-molecular sieve inomthamo okhethiweyo we-adsorption kwaye inokususa umswakama kwi-solvents eziphilayo kunye neegesi, kodwa ayifaki i-solvents kunye neegesi (ezifana ne-tetrahydrofuran).Indlela yokuqala ithatha i-caustic soda dehydration, i-caustic soda iyanyibilika emanzini, akukho lula ukuhlukana ne-tetrahydrofuran emva kokuphelelwa ngamanzi emzimbeni, isebenzisa i-caustic soda ukuba ibe nzima ukuphinda isetyenziswe, ngokwenene iye yanda iindleko.
2. Indlela yokusebenza: Ukusebenza kwe-4A ye-molecular sieve kulula.I-molecular sieve inokufakwa ngokuthe ngqo ekususweni kwe-solvent, okanye isisombululo kunye negesi inokugqithiswa ngokuthe ngqo kwi-molecular sieve adsorption tower.
3. Umthamo we-adsorption: Isihluzo se-Molecular 4A sinomthamo omkhulu we-adsorption, ngokubanzi ngama-22%.
4. Ukukhethwa kokusebenza kwe-adsorption: I-4A i-molecular sieve inokuthatha kalula iimolekyuli zamanzi.Ngenxa yokuba i-diameter yeemolekyuli zamanzi incinci kune-zeolite, ibhalansi ye-electrostatic inokufezekiswa emva kwe-adsorption (i-molecular sieves ayifuni ukufunxa amasuntswana ane-diameters amakhulu kunezo ze-molecular sieves).
I-5.Uhlalutyo ngaphandle kokuvelisa amanzi: I-4a i-molecular sieve ayiyi kukhutshwa emva kokufunxa amanzi kwindawo yokushisa.
6. Ukuhlaziywa kwakhona: Ukuhlaziywa kwe-4A ye-molecular sieve kulula.Emva kweyure enye, initrogen engaphezulu kwama-300°C ingaphinda isetyenziswe (izinto ezingatshiyo zinokumpontshelwa ngqo emoyeni).
7. Ubomi benkonzo ende: I-4A i-molecular sieve inokuvuselelwa iminyaka eyi-3-4.
I-molecular sieves ine-hygroscopicity eqinile yokufuma, ngoko kufuneka isetyenziswe ukuhlanjululwa kwegesi kwaye kufuneka igweme ukudibanisa ngqo nomoya.Iisefu zemolekyuli ezifunxa ukufuma kufuneka zihlaziywe emva kokuba zigcinwe ixesha elide.Izisefu zeemolekyuli zithintela ioli kunye namanzi angamanzi.Zama ukuphepha ukudibanisa neoli kunye namanzi angamanzi ngexesha lokusetyenziswa.Iigesi zokomisa unyango kwiimveliso zoshishino ziquka umoya, i-hydrogen, i-argon, njl.Ukuze kuvumeleke ukusebenza ngokuqhubekayo kwezixhobo, ziyatshintshana.Isixhobo esomisayo sisebenza kubushushu obuqhelekileyo, kwaye senza ukuhlamba umoya ngokutsha kubushushu obungaphezu kwama-340°C.
Inkqubo kunye nomgaqo we-molecular sieve dehydration
Ukuphelelwa ngamanzi emzimbeni yinkqubo ye-adsorption yomzimba.Ukongezwa kwerhasi kubangelwa ubukhulu becala ngumxhuzulane weFani okanye amandla okusasaza.I-adsorption yegesi ifana nokuxinana kwegesi.Ngokuqhelekileyo ayikhethi kwaye yinkqubo ebuyiselwa umva.Ubushushu be-adsorption buncinci kwaye amandla okusebenza afunekayo kwi-adsorption amancinci, ngoko ke isantya se-adsorption ngokukhawuleza, kulula ukufezekisa ukulinganisela.
