Glycol txheej txheem

Triethylene glycol los yog diethylene glycol yog siv los nqus thiab tshem tawm cov dej los ntawm cov pa roj carbon monoxide, uas yog feem ntau siv txoj hauv kev rau lub cev qhuav dej.
Glycol compounds muaj cov dej nqus dej zoo, suav nrog ethylene glycol (xws li), diethylene glycol (DEG), triethylene glycol (TEG) thiab tetraethylene glycol (Treg). Vim tias TEG lub cev qhuav dej muaj qhov poob qis dua thiab qis dua peev thiab cov nqi ua haujlwm, nws tau siv dav.
Ethylene glycol feem ntau yog siv los txhaj cov roj nkev los tiv thaiv kev tsim cov dej;
Diethylene glycol thiab triethylene glycol muaj feem xyuam rau lub cev qhuav dej ntawm cov pa roj carbon monoxide nrog cov dej ntws loj thiab cov dej lwg loj loj hauv qhov chaw kho mob hauv nruab nrab.

Nta:

TEG Lub cev qhuav dej yog hais txog tias lub cev qhuav dej ntawm lub cev tawm los ntawm sab saum toj ntawm lub tshuab nqus tsev thiab tawm mus ntawm chav tsev tom qab kev sib hloov cua sov thiab kev tswj xyuas lub siab los ntawm cov kua roj qhuav cua kub exchanger.

TEG yog tso tawm los ntawm lub hauv qab ntawm lub absorber. Tom qab nkag mus rau hauv lub siab tswj cov cuab yeej, lub tshav kub exchanger nkag mus rau hauv lub tshav kub exchanger ntawm TEG nplua nuj thiab pluag kua kub exchanger. Tom qab hloov tshav kub, nws nkag mus rau TEG rov tsim ntauwd. Nyob rau hauv lub regeneration system, TEG yog thickening. Tom qab rov tsim dua tshiab, TEG cawv cov kua dej tsis zoo yog txias los ntawm peb cov cawv glycol nplua nuj thiab cov kua dej tsis zoo sib pauv thiab txias rau hauv lub twj tso kua mis los kho lub siab. Ntawm no peb tsim TEG, thiab TEG tom qab kev tswj hwm siab nkag mus rau cov roj qhuav ntshiv cov kua kub hloov pauv thiab rov nkag mus rau sab saum toj ntawm lub cev nqus dej ntauwd. Nyob rau hauv txoj kev no, cov txheej txheem ua tiav qhov nqus, rov tsim dua tshiab thiab ncig ntawm TEG. Ntawm lawv, cov roj av vapor thiab ib qho me me ntawm cov pa roj carbon dioxide tawm los ntawm sab saum toj ntawm TEG regeneration pej thuam.

Peb tshwj xeeb hauv kev tsim, R & D, kev tsim khoom, kev teeb tsa ntawm ntau hom roj thiab roj av hauv av kho qhov chaw zoo, kev ua kom huv si, kev kho cov roj crude, lub teeb hydrocarbon rov qab, LNG cog thiab lub tshuab hluav taws xob ntuj.
