Cov kuab tshuaj rho tawm
Cov txheej txheem ntawm kev siv cov kuab tshuaj organic los rho tawm cov tshuaj uas tsis tau raug hu ua organic solle-kua extraction txoj kev ua kua-kua extraction, abluciated li cov kuab tshuaj rho tawm. Nws yog tus txheej txheem hloov pauv loj uas hloov cov khoom siv los ntawm ib theem ua kua rau lwm tus.
Cov kuab tshuaj extraction tau raug thov ua ntej nyob rau hauv petrochemical kev lag luam, cov organic chemistry, tshuaj chemistry thiab tshuaj analytealical. Txawm li cas los xij, yav dhau los 40 xyoo dhau los, vim yog kev txhim kho atomic zog kev tsim tawm, cov kev xav tau tsim muaj roj ultracted, tsis muaj kev lag luam metallgy thiab lwm yam kev lag luam.
Piv nrog sib cais txoj kev xws li graded los nag, thiab kev sib cais ntau dua li kev sib cais zoo, thiab yooj yim ua kom tiav kev tswj tsis zoo xws li ntawd. Yog li ntawd, nws tau maj mam dhau los ua txoj kev loj rau kev sib cais ntau ntau ntawm cov av hauv ntiaj teb.
Cov khoom sib cais ntawm cov kuab tshuaj rho tawm cov qauv tshuaj ntxiv xws li P204 thiab cov kev qhia tawm suab nrov xws li TBP thiab P350. Cov extractants no muaj siab viscosity thiab qhov ceev, ua rau lawv nyuaj rau cais tawm dej. Nws feem ntau yog diluted thiab rov qab siv nrog cov kuab tshuaj xws li kerosene.
Cov txheej txheem rho tawm feem ntau tuaj yeem muab faib ua peb theem loj: kev ntxhua khaub ncaws, ntxuav, thiab rov qab extraction. Cov ntaub ntawv nyoos raw rau kev rho tawm tsis tshua muaj cov hlau thiab cov khoom tawg.
