Kev xaiv cov txheej txheem dehydration rau kev tshem tawm dej los ntawm cov roj ntuj
Kev Taw Qhia Txog Txheej Txheem
Qhov muaj dej nyob rau hauv cov roj av feem ntau ua rau muaj kev rau txim loj: dej thiab cov roj av tsim cov hydrates nyob rau hauv qee qhov xwm txheej, uas thaiv cov kav dej; ntxiv rau, txhawm rau kom ua tau raws li cov ntsuas zoo ntawm cov dej ntsiab lus (lossis dew point) ntawm cov khoom siv roj av, dehydration yog qhov tsim nyog.
Lub kev qhuav dej roj av feem ntau cov txheej txheem suav nrog:
- Kev qhuav dej khov qis kub
- Cov khoom siv desiccant adsorption
- Kev nqus cov kuab tshuaj
- Kev sib cais ntawm daim nyias nyias
Kev ua kom qhuav dej khov uas kub tsawg feem ntau yog ua ke nrog kev rov qab tau cov roj hydrocarbon me me tej yaam num. Thaum cov roj av raug qhuav los ntawm kev sib cais khov, cov roj av yuav tsum muaj lub siab dua lossis qhov chaw txias sab nraud. Vim tias nws yuav tsum tau muaj lub siab lossis qhov chaw txias sab nraud tau muab, nws tsis pheej yig rau lub cuab yeej no.
Cov txheej txheem dehydration adsorption solid desiccant feem ntau yog silica gel, molecular sieve method lossis kev sib xyaw ua ke ntawm ob txoj kev no. Kev nqis peev thiab cov nqi khiav lag luam ntawm cov cuab yeej adsorption siab dua li cov cuab yeej dehydration glycol.
Kev nqus cov kuab tshuaj yog txoj kev siv ntau tshaj plaws. Txawm hais tias muaj ntau cov kuab tshuaj xaiv los ntawm, feem ntau cov khoom siv siv cov kuab tshuaj glycol. Kev sib piv ntawm cov kuab tshuaj dehydration sib txawv tau qhia nyob rau hauv cov lus sib piv ntawm cov kuab tshuaj dehydration.
Kev sib piv ntawm cov tshuaj yaj dej
| Cov tshuaj yaj kom qhuav | qhov zoo dua | qhov tsis zoo | Lus Cim |
| Cov kua dej calcium chloride | Tus nqi khiav lag luam qis thiab cov khoom siv yooj yim | Cov khoom siv tau xeb heev, qhov poob ntawm cov dej noo me me (kwv yees li 11 ° C), thiab H2S hauv cov roj ntuj yuav tsim cov nag lossis daus. | Nws tsis tshua siv tam sim no, feem ntau yog siv rau hauv cov qhov roj nyob deb thiab thaj chaw txias heev. |
| Cov kua dej lithium chloride | Lub dew point tuaj yeem poob rau 22 ~ 36 ℃, uas tsis muaj corrosive rau cov khoom siv dua li calcium chloride aqueous solution. | Kim heev | Feem ntau yog siv rau kev ua kom qhuav cua |
| Cov tshuaj diethylene glycol | Cov tshuaj concentrated yuav tsis khov, cov kuab tshuaj ruaj khov ntawm qhov kub ua haujlwm, hygroscopicity siab | Qhov dew point txo qis los ntawm 28 ℃, uas qis dua li ntawm triethylene glycol kua. Qhov poob ntawm kev nqa mus ntau dua li ntawm triethylene glycol, thiab kev nqis peev ntawm lub cuab yeej yog siab. | Tsis siv dav hauv kev lag luam roj av |
| Triethylene glycol kua | Cov tshuaj uas muaj concentrated yuav tsis khov, cov kuab tshuaj ruaj khov ntawm qhov kub ua haujlwm, thiab qhov hygroscopicity siab heev. Lub zog vapor qis, qhov poob ntawm kev nqa mus los me me, thiab qhov dew point tuaj yeem poob rau 40 ℃. | Kev nqis peev ntawm cov cuab yeej siv siab heev, thiab cov tshuaj muaj qee yam kev nyiam ua npuas dej | Nws yog txoj kev siv dej qhuav tshaj plaws hauv kev lag luam roj av |
Vim tias triethylene glycol muaj qhov dej noo poob loj, tus nqi qis thiab kev ua haujlwm txhim khu kev qha, nws yog qhov pheej yig tshaj plaws ntawm cov glycol compounds. Yog li ntawd, lub cuab yeej no siv triethylene glycol rau kev ua kom lub cev qhuav dej.
