Isicelo/Ukupakisha
Lo mkhiqizo usetshenziselwa ukomisa ngokujulile igesi noma isigaba soketshezi samakhemikhali e-petrochemicals kanye nokomisa amathuluzi.
Isikhwama esilukiwe esingu-25kg/isigubhu sebhodi lephepha esingu-25kg/isigubhu sensimbi esingu-200L noma ngokwesicelo sekhasimende.
Izakhiwo Zesakhiwo Se-I-Alumina esebenzayo
I-alumina esebenzayo inezici zomthamo omkhulu wokumunca, indawo enkulu ethile, amandla aphezulu, kanye nokuzinza okuhle kokushisa. Inamandla amakhulu, iyi-desiccant engenabo ubuthi, engaboli, futhi umthamo wayo ozinzile uphakeme. Isetshenziswa njenge-adsorbent, i-desiccant, i-catalyst kanye nomthwali ezinqubweni eziningi zokusabela njenge-petroleum, umanyolo wamakhemikhali kanye nemboni yamakhemikhali.
I-alumina esebenzayo ingenye yemikhiqizo yamakhemikhali angaphili esetshenziswa kakhulu emhlabeni. Izakhiwo ze-alumina esebenzayo zichazwe ngezansi: I-alumina esebenzayo inokuqina okuhle futhi ifaneleka njenge-desiccant, i-catalyst carrier, i-fluorine removal agent, i-pressure swing adsorbent, i-agent ekhethekile yokuvuselela i-hydrogen peroxide, njll. I-alumina esebenzayo isetshenziswa kabanzi njenge-catalyst kanye ne-catalyst carrier.
I-alumina esebenzayo isetshenziswa njenge-desiccant, esetshenziswa kakhulu emishinini yokomisa umfutho womoya yezimboni, imishini yokomisa umfutho womoya inomfutho osebenzayo, ngokuvamile ingaphansi kuka-0.8Mpa, okudinga isilinganiso se-alumina esebenzayo ukuze ibe namandla amahle omshini, uma amandla omshini ephansi kakhulu, kulula ukuyiphusha, inhlanganisela yempuphu namanzi izovimba ngqo ipayipi lemishini, ngakho-ke, isibonakaliso esibalulekile se-alumina esebenzayo esetshenziswa njenge-desiccant amandla, imishini yokomisa umfutho womoya, ngokuvamile amathangi amabili, amathangi amabili asebenza ngokushintshana, empeleni iyi-adsorption saturation → inqubo yomjikelezo wokuhlaziya, i-desiccant ikakhulukazi amanzi okufutha, kodwa ngaphansi kwezimo zokusebenza ezingokoqobo, umthombo womshini wokufutha umfutho womoya uzoba namafutha, ukugqwala nokunye ukungcola. Lezi zici zizothinta ngqo impilo yesevisi ye-activated alumina adsorbent, ngoba i-activated alumina iyizinto zokufaka amanzi ezimbobo, i-natural adsorption polarity yamanzi, i-oil adsorption nayo inhle kakhulu, kodwa uwoyela uzoxhuma ngqo i-activated alumina adsorption pore, ukuze ukulahlekelwa yizimpawu zokufaka amanzi, kukhona Ukugqwala, ukugqwala emanzini, okunamathiselwe ebusweni be-alumina esebenzayo, Kuzokwenza i-alumina esebenzayo ilahlekelwe umsebenzi ngqo, ngakho-ke ekusetshenzisweni kwe-alumina esebenzayo njenge-desiccant, zama ukugwema ukuthintana namafutha, ukugqwala, impilo yokusetshenziswa ejwayelekile ye-alumina esebenzayo yeminyaka eyi-1 ~ 3, ukusetshenziswa kwangempela kuzoba yindawo yokomisa igesi ukuze kunqunywe ukuthi ithathe indawo ye-alumina esebenzayo. Izinga lokushisa lokuvuselelwa kwe-alumina esebenzayo liphakathi kuka-180 ~ 350℃. Ngokuvamile, izinga lokushisa lombhoshongo we-alumina esebenzayo likhuphukela ku-280℃ amahora ama-4. I-alumina esebenzayo isetshenziswa njenge-ejenti yokwelapha amanzi, kanti isisombululo se-aluminium sulfate sisetshenziswa njenge-regenerator. Ukuhlushwa kwesisombululo se-alumina sulfate regenerator kungu-2 ~ 3%, ukugcwala kwe-alumina esebenzayo ngemuva kokumuncwa kufakwa kusisombululo se-aluminium sulfate, lahla isisombululo, geza ngamanzi ahlanzekile izikhathi ezi-3 ~ 5. Ngemuva kokusetshenziswa isikhathi eside, ubuso be-alumina obusebenzayo buphuzi nsundu futhi umphumela wokususa uketshezi uyancishiswa, okubangelwa ukumuncwa kokungcola. Ingelashwa nge-3% ye-hydrochloric acid isikhathi esisodwa bese ivuselelwa ngendlela engenhla.
