Ikholomu ye-Double Mash inqubo yokuhlukanisa umfutho we-distillation emithathu enemiphumela emithathu
Uhlolojikelele
Ukukhiqizwa kwekholomu ephindwe kabili yenqubo yotshwala bezinga elivamile ikakhulukazi kuhlanganisa umbhoshongo omuhle II, umbhoshongo omahhadlahhadla II, umbhoshongo ocwengiwe I, nombhoshongo omahhadla I. Isistimu eyodwa iqukethe imibhoshongo emibili emahhadla, imibhoshongo emibili emihle, kanye neyodwa. umbhoshongo ungena umusi imibhoshongo emine. Ukucindezela okuhlukile phakathi kombhoshongo nombhoshongo kanye nomehluko wezinga lokushisa usetshenziselwa ukushintshanisa kancane kancane ukushisa nge-reboiler ukuze kufezwe injongo yokonga amandla. Emsebenzini, le mibhoshongo emibili engahluziwe inikezwa ukudla ngesikhathi esisodwa, futhi imibhoshongo emibili emihle iphuza utshwala ngesikhathi esisodwa. Njengamanje, le nqubo iye yakhuthazwa kubakhiqizi abaningi bezinga elivamile lotshwala kanye ne-fuel ethanol.
Okwesithathu, izici zenqubo
1. Ukusetshenziswa kwamandla okuphansi, amathani angu-1.2 ophuzo oludakayo.
2. Isitimu esisodwa sidlula ku-reboiler ukuze kushise umbhoshongo omuhle II, umbhoshongo ocolekileyo II umhwamuko wewayini ushisisa umbhoshongo ongahluziwe II ngomshini wokubilisa kabusha, umbhoshongo ongahluziwe we-II ophezulu wewayini ushisisa ngokuqondile umbhoshongo omuhle I, kanti umbhoshongo omuhle I. Iwayini le-tower top lidlula I-reboiler ishisa ikholomu engahluziwe I. Umbhoshongo owodwa ungena esitimulweni kanye nemibhoshongo emine ukuze uzuze ukuhlangana okushisayo okunemiphumela emithathu zuza ukonga amandla.
3. Ukusebenzisa ingcindezi ehlukile kanye nomehluko wokushisa phakathi kombhoshongo nombhoshongo ukushintsha kancane kancane ukushisa ngokusebenzisa i-reboiler, ukushisa kungasetshenziswa ngezinga eliphezulu, ngaleyo ndlela konga amandla ngokuphumelelayo.
Okwesine, inqubo
Eyesihlanu, indlela yokushisa
Ukhiye wokonga amandla wenqubo imodi yokushisisa. Isitimu esiyinhloko sishiswa ngokungaqondile yi-reboiler ukuhlanza umbhoshongo II. Amanzi ajikijelwe ngesitimu ashisisa kuqala isigaxa sokuvutshelwa esivuthiwe kanye notshwala obungahluziwe abese ebuyela kubhayela wamanzi athambile ukuze aphinde asetshenziswe; umbhoshongo ocwengekile we-II umhwamuko wewayini udlula ku-reboiler. Ikholomu engahluziwe II iyashisisa; ikholomu enhle I-vapor yewayini ishisiswe yi-reboiler kukholamu engahluziwe I.
Kule nqubo, umbhoshongo ongahluziwe I ungumbhoshongo ocindezelayo ongemuhle, umbhoshongo omahhadlahhadla II kanye nombhoshongo omuhle I imibhoshongo yokucindezela komkhathi, kanti umbhoshongo omuhle II uwumbhoshongo wokucindezela okuhle. Umehluko wengcindezi kanye nomehluko wezinga lokushisa kusetshenziselwa ukufudumeza okuhamba kancane. Umbhoshongo owodwa ungena kusitimu nemibhoshongo emithathu ukuze uzuze ukuhlangana okushisayo okunemiphumela emithathu ukuze kufezwe izinjongo zokonga amandla.
Okwesithupha, ukuthambekela kwezinto ezibonakalayo
Umshini wokuvubela onezigaba ezimbili oshisiwe kuqala ungena phezulu kwekholomu I ukuze ukhiphe i-aldehyde, bese uhlukanisa isigaxa sibe izingxenye ezimbili ngomsabalalisi: ingxenye eyodwa ingena kukholomu engamahhadla II, bese enye ingxenye ingena kukholamu emahhadla I. . Ngemva kokuba i-mash evutshiwe ingene embhoshongweni ongahluziwe II, uketshezi olubi luyasuswa phansi kombhoshongo, futhi utshwala obungahluziwe bungena enhlawulo. umbhoshongo I okufanele igxilwe futhi ikhululwe, futhi ingxenye yotshwala obuqediwe ikhishwe emgqeni ongaphezulu ohlangothini.
Ngemva phansi kombhoshongo ocwengekile ngikhanyisa iwayini kanye nombhoshongo ongahluziwe I phezulu kwe-vapor condensate yewayini, ingena embhoshongweni omuhle we-II, igxilise futhi isuse embhoshongweni omuhle we-II, futhi ikhiphe utshwala obuphelile emgqeni ongaphezulu ohlangothini, kanye nokungcola okuphezulu kwamaphuzu abilayo okufana namafutha efuseli Khipha engxenyeni engezansi yombhoshongo omuhle II.
Oyisikhombisa, izinga elijwayelekile lokusetshenziswa kotshwala kanye nethebula lokuqhathanisa ikhwalithi

Inqubo yokukhiqiza i-Ethanol
Okokuqala, izinto zokusetshenziswa Embonini, i-ethanol ngokuvamile ikhiqizwa inqubo yokuvutshelwa kwesitashi noma inqubo ye-ethylene eqondile yokufaka amanzi. I-ethanol yokuvutshelwa yathuthukiswa ngesisekelo sokwenza iwayini futhi kwaba ukuphela kwendlela yezimboni yokukhiqiza i-ethanol isikhathi eside. Izinto ezisetshenziswayo zendlela yokuvubela ikakhulukazi zifaka okusanhlamvu okusanhlamvu (ukolweni, ummbila, amabele, irayisi, amabele, o...
