Ukumuncwa kwamanzi ngesisefo samangqamuzana kuncike emanzini omkhiqizo, 4A imihlahlandlela yokukhipha amanzi ngesisefo samangqamuzana.
1. Ukusetshenziswa: I-4A isisefo se-molecular inamandla okukhangisa futhi ingasusa umswakama kuma-organic solvents namagesi, kodwa ayikhangisi izincibilikisi namagesi (njenge-tetrahydrofuran).Indlela yasekuqaleni ithatha i-caustic soda dehydration, i-caustic soda iyancibilika emanzini, akulula ukuhlukana ne-tetrahydrofuran ngemva kokuphelelwa amandla kwamanzi, isebenzisa i-caustic soda ukuze kube nzima ukugaywa kabusha, empeleni iye yanda izindleko.
2. Indlela yokusebenza: Ukusebenza kokuphelelwa amanzi emzimbeni kwe-4A molecular sieve kulula.Isisefo samangqamuzana singafakwa ngokuqondile ekususeni i-solvent, noma isixazululo negesi kungadluliswa ngokuqondile kumbhoshongo we-adsorption we-molecular sieve.
3. Umthamo we-Adsorption: Isisefo se-Molecular 4A sinamandla amakhulu wokukhangisa, ngokuvamile angama-22%.
4. Ukukhethwa kokusebenza kwe-adsorption: 4A isisefo samangqamuzana singamunca kalula ama-molecule amanzi.Ngenxa yokuthi ububanzi bama-molecule amanzi buncane kune-zeolite, ibhalansi ye-electrostatic ingafinyelelwa ngemva kokukhangisa (izisefo zamangqamuzana azimumbi izinhlayiya ezinobubanzi obukhulu kunalezo zezisefo zamangqamuzana).
I-5.Ukuhlaziya ngaphandle kokukhiqiza amanzi: I-4a yesihlungo se-molecular ngeke ikhululwe ngemva kokumunca amanzi ekamelweni lokushisa.
6. Ukuvuselelwa: Ukuvuselelwa kwe-4A ye-molecular sieve kulula.Ngemva kwehora elilodwa, i-nitrogen engaphezu kuka-300°C ingasetshenziswa futhi (izinto ezingashi zingaphonswa ngokuqondile emoyeni).
7. Impilo ende yesevisi: 4Isihlungi se-molecular singavuselelwa iminyaka engu-3-4.
Izisefo zamangqamuzana zine-hygroscopicity eqinile kumswakama, ngakho kufanele zisetshenziselwe ukuhlanzwa kwegesi futhi kufanele zigweme ukuthintana ngqo nomoya.Izisefo zamangqamuzana ezimunce umswakama kufanele zivuselelwe ngemva kokuba zigcinwe isikhathi eside.Izisefo zamangqamuzana zigwema uwoyela namanzi awuketshezi.Zama ukugwema ukuthintana namafutha namanzi awuketshezi ngesikhathi sokusebenzisa.Amagesi okomisa ukwelashwa emikhiqizweni yezimboni ahlanganisa umoya, i-hydrogen, i-argon, njll. Ama-dryer amabili e-adsorption axhunywe ngokufana, enye isebenza kanti enye ingavuselelwa.Ukuze kuvunyelwe ukusebenza okuqhubekayo kwezinto zokusebenza, ziyashintshana.Isomisi sisebenza ezingeni lokushisa elijwayelekile, futhi senza ukuvuselelwa kabusha kokuwasha umoya ezingeni lokushisa elingaphezu kuka-340°C.
Inqubo kanye nomgomo we-molecular sieve dehydration
Ukuphelelwa amanzi emzimbeni kuyinqubo ye-adsorption ebonakalayo.I-adsorption yegesi ibangelwa kakhulu amandla adonsela phansi Abalandeli noma amandla okusabalalisa.I-adsorption yegesi ifana nokufingqa kwegesi.Ngokuvamile ayikhethi futhi iyinqubo ehlehliswayo.Ukushisa kwe-adsorption kuncane futhi amandla okwenza kusebenze adingekayo ekukhangisweni mancane, ngakho-ke isivinini se-adsorption Ngokushesha, kulula ukufeza ibhalansi.
