Ubuchwepheshe be-Evaporation kanye ne-crystallization
I-Molasses alcohol waste liquid inemiphumela emihlanu yokuhwamuka
Uhlolojikelele
Umthombo, izici kanye nokulimala kwe-molasses amanzi angcolile otshwala
Amanzi angcolile e-Molasses alcohol angamanzi angcolile anombala omningi futhi anombala ophezulu akhishwa endaweni yokusebenzela yotshwala yefekthri kashukela ukuze kukhiqizwe utshwala ngemva kokuvutshelwa kwe-molasses. Icebile ngamaprotheni nezinye izinto eziphilayo, futhi iqukethe nosawoti wezinto ezingaphili njenge-Ca ne-Mg kanye nokugxila okuphezulu. SO2 nokunye. Ngokuvamile, i-pH yamanzi angcolile yotshwala ingu-4.0-4.8, i-COD ingu-100,000-130,000 mg/1, i-BOD ingu-57-67,000 mgSs, 10.8-82.4 mg/1. Ngaphezu kwalokho, iningi lalolu hlobo lwamanzi angcolile lune-acidic, futhi umbala uphakeme kakhulu, onsundu-omnyama, ikakhulukazi ohlanganisa umbala we-caramel, umbala we-phenolic, umbala we-Maillard njalonjalo. Njengoba uketshezi lwemfucuza luqukethe cishe u-10% okuqinile, ukugxila kuphansi futhi akukwazi ukusetshenziswa. Uma ikhishelwa emifuleni nasemapulazini ngaphandle kokwelashwa, izongcolisa kakhulu izinga lamanzi kanye nemvelo, noma ibangele ukugcwala nokucinana komhlabathi, kanye nokukhula kwezifo zezitshalo. Indlela yokubhekana nokusebenzisa i-molasses alcohol waste liquid kuyinkinga enkulu yemvelo ebhekene nemboni kashukela.
I-Molasses alcohol waste liquid igqwala kakhulu futhi ine-chroma ephezulu, okunzima ukuyikhipha ngendlela ye-biochemical. Ukushiswa okugxilile noma umanyolo owuketshezi osebenza kahle kakhulu wuhlelo lokwelapha oluphelele njengamanje.
Idivayisi isebenzisa isistimu yokuhwamuka okuphoqelekile enemiphumela emihlanu yokujikeleza, enesitimu esigcwele njengomthombo wokushisa, ukushisisa okunomphumela owodwa nomsebenzi onemiphumela emihlanu. Uketshezi lwemfucuza yotshwala obunama-molasses okugxiliswe ku-5 kuya ku-6% lugxilile futhi luhwamuke, futhi udaka olugxilile olunokugxiliswa kuka-≥ 60% luthunyelwa kubhayela ukuze lushiswe, futhi ukushisa okukhiqizwa kwanelisa kakhulu isitimu somshini. Thuthukisa amanzi ajiyile uwabuyisele esigabeni sangaphambilini ukuze uthole amanzi ahlanjululwayo.
Okwesibili, ishadi lokugeleza kwenqubo
Okwesithathu, izici zenqubo
1. Setha i-evaporator eyisipele ukuze isule okokusebenza, okungaqaphela ukuhlanzwa okunganqamuki nokuqinisekisa ukukhiqizwa okuqhubekayo.
2. Idivayisi isebenzisa ukulawula uhlelo oluzenzakalelayo ukuze konge izindleko zabasebenzi.
3. Ukusebenza kahle kokucubungula okuphezulu nokusebenza okuzinzile.
4. Ngokusebenzisa i-slurry ewugqinsi ukuze ubuyele kubhayela, ama-molasses angakhiqiza utshwala ngaphandle kokwengeza uphethiloli.
5. I-evaporator eyisipele isethelwe umphumela wokukhipha, ongabona ukuhlanzwa okunganqamuki nokuqinisekisa ukukhiqizwa okuqhubekayo.
6. Utshwala bungakhiqizwa ngama-molasses ngaphandle kokwengeza uphethiloli ngodaka oluwugqinsi kubhayela ukuze lusetshenziswe kabusha kanye nama-molasses.

Ikholomu ye-Double Mash enemiphumela emithathu umehluko...
Uhlolojikelele Ukukhiqizwa kokukhishwa kwe-distillation kwamakholomu amabili wenqubo yotshwala bezinga elivamile ikakhulukazi kuhlanganisa umbhoshongo omuhle II, umbhoshongo omahhadla II, umbhoshongo ocolisisiwe I, kanye nombhoshongo omahhadla I. Olunye uhlelo luqukethe imibhoshongo emibili emaholoholo, imibhoshongo emibili emihle, kanye umbhoshongo owodwa ungena embhoshongweni imibhoshongo emine. Ukucindezela okuhlukile phakathi kombhoshongo nombhoshongo kanye nomehluko wezinga lokushisa usetshenziselwa ukukhipha kancane kancane...

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...

Inqubo ye-Threonine i-crystallization ngokuqhubekayo
Isingeniso se-Threonine i-L-threonine i-amino acid ebalulekile, futhi i-threonine isetshenziswa kakhulu kwezokwelapha, ama-reagents amakhemikhali, iziqinisi zokudla, izithasiselo zokudla, njll. Ikakhulukazi, inani lezithako zokudla likhula ngokushesha. Ivamise ukungezwa ekudleni kwamantshontsho engulube nezinkukhu. Ingeyesibili i-amino acid ekhawulelwe ekudleni kwezingulube kanye neyesithathu i-amino acid ekhawulelwe ekudleni kwezinkukhu. Yengeza u-L-th...
