Iinkqubo ze-TEG zokuphelelwa ngamanzi emzimbeni kwirhasi yendalo

Iinkqubo zeFUkuphelelwa ngamanzi kwe-TEG kwigesi yendaloyindlela eqhelekileyo yokususa amanzi kwigesi yendalo.
Irhasi yendalo emanzi yendalo ihlulwe kumathontsi angama-5 μm nangaphezulu ngesahluli sokucoca kwaye emva koko ungene kwigumbi lokwahlula lolwelo lwerhasi kwindawo esezantsi yenqaba yokufunxa ye-triethylene glycol yeyunithi yokuphelelwa ngamanzi ukuze yahlule ulwelo lwasimahla olungangeniswa kulo. inqaba yokufunxa xa isahluli sokucoca sikwimeko yengozi.Ingena kwicandelo lokufunxa ngokunyuka kwenqaba yokufunxa.I-triethylene glycol ehlaziyiweyo ifakwe phezulu kwi-absorber ukuze idibanise ngokupheleleyo ne-bottom-up yendalo yegesi kwi-absorber yokudlulisa ubuninzi kunye nokutshintshiselana ukususa amanzi.Ukufuma okususiweyo kwerhasi yendalo kususwa yinqaba yokubambisa inkungu ngaphezulu kwe-5 μm ye-glycol iphuma kwinqaba.
Emva kokushiya inqaba, itshintshisa ubushushu kunye ne-glycol eshushu eshushu ngaphambi kokungena kwinqaba nge-casing exchanger heat exchanger ukunciphisa ubushushu be-triethylene glycol engena kwinqaba.Irhasi yendalo emva kokutshintshiselana kobushushu ingena kwisahluli sokucoca ukwahlula i-glycol eqhutywayo kwaye emva koko ingene kumbhobho wokuthumela ngaphandle.I-triethylene glycol etyebileyo efunxa amanzi kwirhasi yendalo iphuma kwinqaba yokufunxa kwaye ingene kwivalve elawula inqanaba lolwelo.Emva koxinzelelo, ingena kwipleyiti yokupholisa ye-reflux ngaphezulu kwekholamu yolwelo olutyebileyo lwe-distillation, itshintshise ubushushu kunye nomphunga oshushu owenziwe kwi-reboiler, ibonelela ngesikhundla sokupholisa se-reflux ngaphezulu kwekholamu, ifudunyezwe ukuya kuma-50 ℃, kwaye umbhobho wokuphuma ungena kwitanki ye-triethylene glycol flash.I-glycol ecebileyo igxininisekile kwi-0.4MPa ~ 0.6MPa kwi-flash tank, kunye negesi ye-hydrocarbon kunye nezinye iigesi ezichithwe kwi-triethylene glycol zikhanyisa, ezisetyenziswa njengegesi yegesi yokutsha kwe-reboiler.
I-flash rich liquid triethylene glycol ingena kwisihluzo somatshini ukuhluza ukungcola komatshini, kwaye ingena kwisihluzo sekhabhoni esebenzayo ukuqhubela phambili i-adsorb ye-hydrocarbons enyibilikisiweyo kwi-triethylene glycol kunye nezinto zokuthotywa kwe-triethylene glycol.Emva koko ingena kwipleyiti etyebileyo kunye nehlwempuzekileyo yokutshintshiselana kobushushu ukutshintshisa ubushushu kunye nobushushu obuphezulu be-lean triethylene glycol ukusuka kwitanki yebuffer yokutshintsha ubushushu kwindawo esezantsi ye-triethylene glycol reboiler.Ukutshintshana kobushushu kuyenyuka ukuya kwi-120 ~ 130 ℃ kwaye kungena kwikholomu yolwelo olutyebileyo lwe-distillation.
Kwi-triethylene glycol reboiler kwindawo engezantsi yekholomu ye-distillation, i-triethylene glycol ifudumala ukuya kwi-193 ℃, kwaye amanzi kwi-triethylene glycol ahlulwe kwaye akhutshwe ukusuka phezulu kwikholomu ye-distillation ngokusebenzisa i-fractionation yekholomu ye-distillation.I-glycol ebhityileyo kunye noxinaniso malunga ne-99% (WT) iphuphuma ukusuka kwikholamu yokuhlubula ulwelo olubhityileyo kwi-reboiler ukuya kwitanki esezantsi ye-triethylene glycol yokutshintsha ubushushu.Ngaphantsi kwesenzo serhasi eyomileyo kwikholamu yokuhlubula ulwelo olubhityileyo, ukuxinwa kwe-glycol ebhityileyo engena kwitanki yesithinteli sobushushu kunokufikelela kwi-99.5% ~ 99.8%.
Kwitanki ye-glycol buffer, i-glycol ebhityileyo eneqondo lobushushu elimalunga ne-193 ℃ ingena kwisityebi nesihlwempuzekileyo sokutshintsha ubushushu be-glycol ukutshintshiselana ngobushushu kunye ne-glycol etyebileyo.Xa ubushushu behla ukuya malunga ne-100 ℃, ingena kwimpompo.I-triethylene glycol e-Lean impontshelwa kwi-gas-liquid exchanger heat exchanger ngaphandle kwe-absorber ngempompo, ipholile kunye ne-outlet yegesi yokutshintshiselana kobushushu, kwaye ingena kumphezulu we-absorber ukusuka kwindawo ephezulu ye-casing ukugqiba ukujikeleza kwe-solvent.
Umjelo werhasi eyomileyo uphuma kwicandelo lombhobho werhasi owomileyo kwindawo yokuphuma yesibambi kwaye ungene kumbhobho wokufudumeza werhasi owomileyo wetanki yebuffer yokutshintsha ubushushu kwindawo engezantsi ye-triethylene glycol reboiler.Emva kokuba ifudunyezwe yi-lean triethylene glycol, iyathotywa ukuya kwi-0.4MPa ngevalve elawula uxinzelelo olusebenza ngokwayo kwaye ingene kwitanki yesithinteli segesi yamafutha.Emva kokushiya itanki yesithinteli segesi yamafutha, yohlulwe ngeendlela ezimbini.Enye indlela ishushu kwaye ingene kwindawo esezantsi yolwelo olubhityileyo ikholamu njengolwelo olubhityileyo lwerhasi;Enye yirhasi yepetroli esetyenziswa njengebhoyila.
