Amanzi kunye nokungcola okukhoyo kwi-solvents zizinto ezingalunganga kwiinkqubo zoshishino, kwaye kufuneka zisuswe nge-zeolite molecular sieves, eyaziwa ngokuba yi-solvent drying okanye i-solvent treatment. Ngobukhulu obuchanekileyo bepore kunye nozinzo lwekhemikhali, iisefu zemolekyuli azinakuphinda zifumaneke kwaye zisebenza ngokugqwesileyo kwizixhobo zokunyanga isinyibilikisi, ngakumbi kwimizi-mveliso yeekhemikhali kunye namayeza.
Iingxaki eziqhelekileyo kuNyango lweSolunti
I-solvents ye-industrial isoloko iqulethe ukungcola, njengamanzi amaninzi (awona manzi amaninzi kunye neyona mpembelelo), i-acidic okanye i-alkaline substances, izinto eziphilayo, kunye neegesi ezingcolileyo (i-carbon dioxide, i-nitrogen, kunye ne-hydrocarbons) eyaziswa emva kokubuyiswa kwe-solvent, njl.
Iimpembelelo zala manzi kunye nokungcola kwiinkqubo zemizi-mveliso ziquka (kodwa kungaphelelanga apho): ukuphazamisana neekhemikhali, iipropathi zemathiriyeli ezithoba isidima, ukubeka imingcipheko yokusingqongileyo kunye nempilo. Ngoko ke kufuneka zisuswe ukwanelisa iimfuno zenkqubo, kunye nokuthintela ukuthotyelwa kumgangatho wemveliso kunye nokuphinda kusetyenziswe izinyibilikisi.
Kutheni i-Molecular Sieve ingenakuTshintshwa?
Ukusebenza kakuhle: Izisefu zeemolekyuli zinomthamo we-adsorption ophezulu kakhulu kunye nesantya se-adsorption, ezenza ukuba zikwazi ukususa ngokufanelekileyo amanzi kwizinyibilikisi ngexesha elifutshane, kwaye ngaloo ndlela ziphucula ukusebenza kakuhle ukomisa.
Ukukhetha: Iisefu zemolekyuli zikhetha ngokukhetha iimolekyuli zokungcola ngaphandle kokuchaphazela kakhulu ezinye iinxalenye kwi-solvent. Le propati ye-adsorption ekhethiweyo inika i-molecular sieves iingenelo ezizodwa kwiinkqubo zonyango lwe-solvent.
Ukuzinza: Njengezinto ezigqwesileyo ze-adsorption, i-molecular sieves ibonisa ukuzinza okuphezulu kwe-thermal kunye nokuzinza kweekhemikhali, kwaye inokugcina ukusebenza kwe-adsorption ezinzileyo phantsi kweemeko ezahlukeneyo zokusebenza kunye neemeko ze-kinetic.
Ukuhlaziya: Iisefu ze-molekyuli ziyinto ehambelana nokusingqongileyo, kwaye ukusebenza kwazo kwe-adsorption kunokubuyiselwa ngenkqubo yokuvuselela, ukuvumela ukuphinda kusetyenziswe kwaye ngaloo ndlela kuncitshiswe iindleko zoqoqosho.
I-Sieves ye-Molekyuli yoNyango lwe-Solvent
Uhlobo lwe-3A ye-Zeolite ye-Molecular Sieve: Ifanelekile ukomisa i-molecule encinci ye-solvents ye-polar efana ne-ethanol, i-methanol, i-acetone, i-DMF, i-THF, njl.
Chwetheza i-4A Zeolite Molecular Sieve: Yeyona nto isetyenziswa ngokuqhelekileyo kwaye inexabiso -idesiccant esebenzayo nenamandla okufunxa. Ifanelekile ukomisa izinyibilikisi zepolar eziphakathi ezifana nekloroform, i-dichloromethane, i-ether, i-ethane kunye njl.
Uhlobo lwe-5A ye-Zeolite ye-Molecular Sieve: Iyakwazi ukufunxa amanzi, i-carbon dioxide, i-hydrogen sulfide, kunye neemolekyuli ezincinci ezifana ne-alkanes. Ilungele ukunyanga i-solvents exubeneyo, ukususa ukungcola kwe-polar, kunye nokwahlula ii-hydrocarbons.
Uhlobo lwe-13X ye-Zeolite ye-Molecular Sieve: Inobungakanani obukhulu bepore kunye nomthamo ophezulu we-adsorption, kwaye ifanelekile kunyango lwe-polar kunye-nonyango lwe-solvent. Isetyenziselwa kakhulu ukususa amanzi kunye nokungcola kwi-solvents efana ne-aromatics kunye ne-alkanes.
