Qhov Tseem Ceeb Qhov Sib Txawv - Batch vs Continuous Distillation
Batch distillation thiab txuas ntxiv distillation yog hom txheej txheem distillation. Qhov sib txawv tseem ceeb ntawm batch thiab nruam distillation yog tias batch distillation yog ua tiav nyob rau hauv batch-wise whereas nruam distillation yog ua raws li ib tug tas mus li txheej txheem.
Distillation yog cov txheej txheem tshuaj uas siv los cais cov khoom sib xyaw ua ke.
Batch Distillation yog dab tsi?
Batch distillation yog txoj hauv kev ntawm kev sib cais cov khoom hauv kev sib xyaw ua ke. Hauv txoj kev no, kev sib cais ntawm distillation yog ua ntau zaus. Batch distillation yog ib qho yooj yim mus nqa tawm. Cov txheej txheem no muab cov purity siab heev ntawm cov tshuaj sib cais thiab qhov siab tshaj plaws ntawm cov txheej txheem (ib txheej txheej txheej txheem tuaj yeem ua ntau yam tshuaj sib txawv).
Ib pawg distillation tuaj yeem ua tiav hauv ib kem distillation. Nyob ntawd, ntau yam khoom siv tuaj yeem muab cais ua cov khoom siv sib cais. Thaum distillation ntawm ib pawg ua tiav, kem tuaj yeem siv rau qhov sib txawv kiag li sib xyaw kom sai thiab ua tau zoo. Thiab tseem, cov txheej txheem no tuaj yeem ua tiav tag nrho.
Daim duab 01: Daim duab yooj yim Qhia cov Cheebtsam ntawm cov khoom siv Distillation
Txawm li cas los xij, batch distillation yog qhov raug mob ntau heev. Tias yog vim li cas, thaum lub kem yog siv rau ib tug nyias muaj nyias ib batch tom qab ua tiav ntawm ib tug distillation, tus nqi ntawm cov batch yav dhau los yuav nyob twj ywm nyob rau hauv lub system thiab yog li, cov nram qab no batch yuav kis tau (yog hais tias cov nram qab no batch yog zoo tib yam rau lub batch. yav dhau los batch, qhov no tsis yog ib yam dab tsi yuav tsum muaj kev txhawj xeeb).
Ntawm Distillation yog dab tsi?
Nruam distillation yog txoj kev ntawm kev sib cais cov khoom sib xyaw ua ke siv cov txheej txheem txuas ntxiv. Tsis muaj kev cuam tshuam rau cov txheej txheem no kom txog thaum ua tiav cov distillation. Txoj kev no muaj kev ua haujlwm siab rau kev sib cais. Tus nqi ntawm cov sib tov siv rau kev sib cais tsis muaj kev txwv raws li rau batch distillation.
Daim duab 02: Daim duab yooj yim uas qhia cov txheej txheem Nruam Distillation
Qhov kev ua kom tsis tu ncua yog cov txheej txheem kim thaum piv nrog cov batch distillation. Cov txheej txheem no yuav tsum muaj ntau cov kab distillation ntau dua li ntawm batch distillation; Tus naj npawb ntawm cov kab uas yuav tsum tau muaj rau qhov txuas ntxiv distillation yog qhia raws li N-1 whereas N yog tus naj npawb ntawm cov khoom sib cais los ntawm distillation.
Qhov txawv ntawm Batch thiab Nruam Distillation yog dab tsi?
Batch vs Nruam Distillation |
|
| Batch distillation yog txoj hauv kev ntawm kev sib cais cov khoom hauv cov khoom sib xyaw ua ke. | Nruam distillation yog txoj kev ntawm kev sib cais cov khoom sib xyaw ua ke siv cov txheej txheem txuas ntxiv. |
| Tus naj npawb ntawm Distillation Columns | |
| Batch distillation yuav tsum tau ib kem distillation. | Nruam distillation yuav tsum tau N-1 kab uas N yog tus naj npawb ntawm cov khoom yuav tsum tau sib cais. |
| Efficiency | |
| Qhov kev ua tau zoo ntawm cov txheej txheem batch distillation yog qis dua piv rau cov distillation tas li. | Qhov kev ua tau zoo ntawm cov txheej txheem distillation txuas ntxiv yog siab heev. |
| Flexibility | |
| Batch distillation yog qhov hloov pauv tau yooj yim vim tias ntau qhov sib txawv tuaj yeem sib cais siv ib kab distillation. | Nruam distillation tsis hloov pauv vim tias muaj ntau cov kab distillation siv rau txhua qhov sib cais ntawm qhov sib tov. |
| Hloov qhov sib xyaw | |
| Nyob rau hauv cov txheej txheem distillation, tom qab ua tiav ntawm distillation ntawm ib pawg, kem tuaj yeem siv rau cov khoom sib txawv kiag li sib xyaw kom sai thiab ua tau zoo. | Nyob rau hauv cov txheej txheem distillation tas mus li, nws yuav siv sij hawm ntev los hloov cov sib tov uas tau distilled. |
Summary – Batch vs Continuous Distillation
Distillation yog cov txheej txheem ntawm kev sib cais cov khoom sib xyaw ua ke los ntawm kev ua kom sov thiab txias. Muaj ob hom kev distillation loj; batch distillation thiab tsis tu ncua distillation. Qhov txawv ntawm batch thiab nruam distillation yog tias batch distillation yog ua tiav hauv batch-wise whereas nruam distillation yog ua tiav raws li tus txheej txheem tas mus li.
