Tsarin bushewar iskar gas ta TEG

Tsarin aiki na Rashin ruwa a cikin iskar gas ta TEG hanya ce ta al'ada ta cire ruwa a cikin iskar gas.
Ana raba iskar gas mai cike da ruwa daga digo 5 μm zuwa sama ta hanyar raba matattarar sannan a shiga ɗakin raba iskar gas da ruwa a ƙasan hasumiyar sharar triethylene glycol na na'urar bushewa don raba ruwan da ba shi da ruwa wanda za a iya kawowa cikin hasumiyar sharar lokacin da mai raba matattarar ke cikin haɗari. Yana shiga sashin sharar ta hanyar tayar da hasumiyar sharar. Ana allurar triethylene glycol da aka sake sabuntawa a saman mai sharar don ya taɓa gaba ɗaya da iskar gas ta ƙasa zuwa sama akan mai sharar don canja wurin taro da musanya don cire ruwa. Ana cire iskar gas da aka cire daga danshi ta hanyar mai kama hazo na saman hasumiya don digo glycol sama da 5 μm daga hasumiyar.
Bayan ya bar hasumiyar, yana musayar zafi da glycol mai zafi kafin ya shiga hasumiyar ta hanyar musayar zafi don rage zafin triethylene glycol da ke shiga hasumiyar. Iskar gas bayan musayar zafi tana shiga mai raba matattarar don raba glycol da aka ɗauka sannan ta shiga bututun fitarwa. Mai arzikin triethylene glycol wanda ke sha ruwan da ke cikin iskar gas ɗin yana fitowa daga hasumiyar sha kuma yana shiga bawul mai daidaita matakin ruwa. Bayan rage matsin lamba, yana shiga farantin sanyaya reflux a saman ginshiƙin distillation na ruwa mai arziki, yana musayar zafi da tururin zafi da aka samar a cikin rebooter, yana samar da ƙarfin sanyaya reflux a saman ginshiƙin, ana dumama shi zuwa kusan 50 ℃, kuma bututun fitarwa yana shiga tankin flash na triethylene glycol. Ana rage matsin lamba zuwa 0.4MPa ~ 0.6MPa a cikin tankin flash, kuma ana fitar da iskar hydrocarbon da sauran iskar gas da aka narkar a cikin triethylene glycol, wanda ake amfani da shi azaman iskar mai don ƙone rebooter.
Ruwan triethylene glycol mai cike da haske yana shiga matatar injin don tace dattin injin, sannan ya shiga matatar carbon da aka kunna don ƙara shaye hydrocarbons da aka narkar a cikin triethylene glycol da abubuwan da ke lalata triethylene glycol. Sannan yana shiga farantin mai cike da zafi da mara kyau don musanya zafi tare da triethylene glycol mai laushi mai zafi daga tankin musayar zafi a ƙasan tukunyar triethylene glycol. Musayar zafi tana tashi zuwa 120 ~ 130 ℃ kuma tana shiga ginshiƙin distillation na ruwa mai cike da ruwa.
A cikin injin sake tafasa triethylene glycol da ke ƙasan ginshiƙin distillation, ana dumama triethylene glycol zuwa 193 ℃, kuma ruwan da ke cikin triethylene glycol zai rabu ya kuma fita daga saman ginshiƙin distillation ta hanyar raba ginshiƙin distillation. Lean glycol mai yawan kusan 99% (WT) yana kwarara daga ginshiƙin distilling ruwa mai laushi a cikin injin sake tafasa zuwa ƙaramin tankin distillation na musayar zafi na triethylene glycol. A ƙarƙashin aikin busasshen iskar gas a cikin ginshiƙin distilling ruwa mai laushi, yawan glycol mai laushi wanda ke shiga cikin tankin distillation na musayar zafi zai iya kaiwa 99.5% ~ 99.8%.
A cikin tankin glycol buffer, glycol mai laushi mai zafin jiki na kimanin 193 ℃ yana shiga mai musayar zafi na glycol mai arziki da mara kyau don musanya zafi tare da mai arziki glycol. Lokacin da zafin ya faɗi zuwa kusan 100 ℃, yana shiga famfo. Ana tura lean triethylene glycol cikin mai musayar zafi na gas-liquid a wajen mai sha ta famfo, sannan a sanyaya shi da mai musayar zafi na gas, sannan a shiga saman mai sha daga saman murfin don kammala zagayawa na narkewa.
Ana fitar da kwararar iskar gas daga sashin busasshen bututun iskar gas a wurin fitar da mai sha kuma yana shiga bututun dumama iskar gas mai busasshe na tankin musayar zafi a ƙasan tukunyar triethylene glycol. Bayan an dumama shi da siririn triethylene glycol, ana tura shi zuwa 0.4MPa ta cikin bawul ɗin da ke daidaita matsin lamba da kansa sannan ya shiga tankin mai. Bayan ya bar tankin mai, ana raba shi zuwa hanyoyi biyu. Hanya ɗaya ana dumama ta shiga ƙasan bututun mai mai laushi a matsayin iskar gas mai cire ruwa mai laushi; ɗayan kuma shine iskar mai da ake amfani da ita azaman tukunya mai sake tafasa.
