Usoro nke akpịrị ịkpọ nkụ TEG na gas

Usoro nke Fakpịrị ịkpọ nkụ TEG na gas ekebụ ụzọ nkịtị isi wepụ mmiri na gas.
A na-ekewa ikuku ikuku mmiri juru eju site na ụmụ irighiri mmiri 5 μm na n'elu site na nkesa nzacha wee banye n'ime ụlọ nkewa nke mmiri gas na akụkụ ala nke triethylene glycol absorption ụlọ elu nke akpịrị ịkpọ nkụ iji kewaa mmiri mmiri n'efu nke enwere ike ibubata. ụlọ elu absorption mgbe ihe nkesa nzacha nọ na ọnọdụ mberede.Ọ na-abanye na ngalaba nnabata site na riser nke ụlọ elu nke absorption.A na-agbanye triethylene glycol a na-emezigharị n'ime elu nke ihe na-ekpuchi ya ka ọ na-ejikọta ya na gas na-emepụta ihe na-emepụta ihe na-ekpo ọkụ maka oke nnyefe na mgbanwe iji wepụ mmiri.A na-ewepụ mmiri mmiri ewepụrụ gas sitere n'okike site na ụlọ elu elu alụlụ ọgụ maka ihe karịrị 5 μm glycol na-adapụ n'ụlọ elu ahụ.
Mgbe ọ hapụsịrị ụlọ elu ahụ, ọ na-agbanwe okpomọkụ na glycol na-ekpo ọkụ na-ekpo ọkụ tupu ya abanye n'ụlọ elu ahụ site na mkpuchi mkpuchi mkpuchi mkpuchi iji belata okpomọkụ nke triethylene glycol na-abanye n'ụlọ elu ahụ.The eke gas mgbe okpomọkụ mgbanwe abanye nzacha separator kewapụ ebu glycol na mgbe na-abanye na mbupụ pipeline.Triethylene glycol bara ụba nke na-amịkọrọ mmiri dị na gas sitere n'okike na-esi na ụlọ elu absorption pụta wee banye na ọkwa mmiri na-achịkwa valvụ.Mgbe ịda mbà n'obi gasịrị, ọ na-abanye na efere reflux jụrụ oyi n'elu kọlụm distillation mmiri bara ụba, na-agbanwe okpomọkụ na uzuoku na-ekpo ọkụ na-emepụta na reboiler, na-enye ike reflux jụrụ oyi n'elu kọlụm, na-ekpo ọkụ ruo ihe dịka 50 ℃, na ọkpọkọ ọpụpụ na-abanye na triethylene glycol flash tank.Ọgaranya glycol na-ada mbà n'obi ruo 0.4MPa ~ 0.6MPa na flash tank, na hydrocarbon gas na ndị ọzọ gas etisasịwo na triethylene glycol na-flashshed, nke a na-eji dị ka mmanụ ụgbọala gas maka combustion nke reboiler.
Mmiri mmiri triethylene glycol na-egbuke egbuke na-abanye n'ime ihe nzacha iji wepụ ihe adịghị arụ ọrụ, wee banye n'ime ihe nzacha carbon na-arụ ọrụ iji mee ka hydrocarbons gbazere na triethylene glycol na ihe ndị na-emebi emebi nke triethylene glycol.Mgbe ahụ, ọ na-abanye na efere nke ọgaranya na nke na-adịghị mma na-ekpo ọkụ na-ekpo ọkụ iji gbanwee okpomọkụ na triethylene glycol na-ekpo ọkụ na-ekpo ọkụ site na tankị mgbanwe okpomọkụ na akụkụ ala nke triethylene glycol reboiler.Mgbanwe okpomọkụ na-ebili na 120 ~ 130 ℃ wee banye na kọlụm distillation mmiri bara ụba.
Na triethylene glycol reboiler na akụkụ ala nke kọlụm distillation, triethylene glycol na-ekpo ọkụ ruo 193 ℃, na mmiri dị na triethylene glycol na-ekewa ma wepụ ya n'elu kọlụm distillation site na mpempe akwụkwọ nke kọlụm distillation.Lean glycol nke nwere ihe dị ka 99% (WT) na-ejupụta site na kọlụm na-ewepụ mmiri na-adịghị ahụkebe na reboiler na ala triethylene glycol okpomọkụ ihe nchekwa tank.N'okpuru ọrụ nke gas akọrọ na kọlụm na-ewepụ mmiri mmiri, ịta glycol na-abanye na tankị mgbanwe okpomọkụ nwere ike iru 99.5% ~ 99.8%.
N'ime tank nke glycol, glycol na-adabere na okpomọkụ nke ihe dịka 193 ℃ na-abanye na ọgaranya na ogbenye glycol okpomọkụ mgbanwe mgbanwe okpomọkụ na glycol bara ọgaranya.Mgbe okpomọkụ na-adaba na ihe dịka 100 ℃, ọ na-abanye na mgbapụta.Lean triethylene glycol na-agbaba n'ime gas-mmiri okpomọkụ Exchanger n'èzí absorber site mgbapụta, mma na outlet gas okpomọkụ Exchanger, wee banye n'elu nke absorber si n'elu nke casing iji mezue ihe mgbaze mgbasa.
A na-ebute mmiri nke gas kpọrọ nkụ site na mpaghara ọkpọkọ gas akọrọ na ntinye nke onye na-ekpo ọkụ ma na-abanye na ọkpọkọ ọkụ ọkụ gas na-ekpo ọkụ nke tankị mgbanwe okpomọkụ na akụkụ ala nke triethylene glycol reboiler.Mgbe emechara ya ọkụ site na triethylene glycol, a na-atụgharị ya na 0.4MPa site na valvụ na-arụ ọrụ nke onwe ya wee banye na tankị nchekwa mmanụ.Mgbe ọ hapụsịrị tankị nchekwa mmanụ ọkụ, a na-ekewa ya n'ụzọ abụọ.Otu ụzọ na-ekpo ọkụ ma na-abanye n'ime akụkụ ala nke kọlụm na-ekpochapụ mmiri mmiri dị ka mmiri na-ekpochapụ gas;Nke ọzọ bụ mmanụ ụgbọala gas eji dị ka reboiler.
