Kev nthuav dav thiab kev kub siab yog txhua qhov txuas uas yuav tsum tau muaj kev paub hauv cov txheej txheem tshuaj thiab tshuaj, yog li cov khoom siv ntxiv thiab cov khoom siv siab tseem yog cov khoom siv tsis tseem ceeb hauv kev ua haujlwm. Ntawm no yog qhov rho tawm thiab cov tshuab concentration, uas muaj ob qho tib si rho tawm thiab cov khoom siv. Txo cov khoom siv nqis peev, tab sis kuj txhim kho cov haujlwm ua haujlwm. Yog lawm, cov yam ntxwv ntawm cov tuab ntawm cov khoom siv methylal extraction tau tshaj rau ntau dua li cov no, dab tsi yuav tsum txhawj xeeb?
Chav tsev rho tawm thiab cov ntim khoom muaj tus hneev me me, thiab hauv kev siv, nws tuaj yeem txuas nrog dej thiab hluav taws xob; cov kab ke nruab nrog reflux condenser, reflux txias, roj-dej separator thiab lwm yam khoom siv, uas tuaj yeem rov qab tau cov khoom xyaw rov qab rau hauv cov khoom siv; lub tshuab txais yuav Nws yog kev ua kom muaj roj kub kom muaj cua kub, txawm tias cua sov, nyab xeeb thiab txhim khu kev qha.
Nyob rau tib lub sijhawm, cov khoom siv methylal muaj nws tus kheej evaporative concentrator, uas tsis tsuas yog muaj ntau dua qhov kev ua haujlwm zoo, tab sis kuj muaj cov tshuaj lom zoo nyob ntawm 1,1 mus rau 1.3, uas tuaj yeem hloov kho rau cov dej tawm, dej cawv lossis cov kuab tshuaj tawm, thiab muaj zoo siv. Vim tias tag nrho cov kev tshem tawm, kev xav thiab rov qab los yog nqa tawm hauv txoj kev kaw qhov dej, ntau yam kev tsis txaus siab zam tau. Hauv ntej, chav ntsuas tau muaj qhov zoo ntawm qhov kev ua haujlwm ntau, kev ua haujlwm siab, kev txuag hluav taws xob, thiab kev ua haujlwm dav, thiab nws yog ib qho khoom siv zoo tshaj plaws.
