Maitiro eF Kupera simba kwemvura muTEG mugasi rechisikigo inzira yakajairika yekubvisa mvura mugasi rechisikigo.
Gasi rechisikigo rakanyorova rinoparadzaniswa kubva kumadonhwe e5 μm zvichikwira kuburikidza nefirita rinopatsanura uye rozopinda mukamuri rekuparadzanisa gasi-liquid riri pasi petriethylene glycol absorption tower yechikamu chemvura inoyerera kuti riparadzanise mvura yakasununguka inogona kuunzwa mufirita inonyudzwa kana firita rinopatsanura riri munjodzi. Rinopinda muchikamu chekunyudzwa kuburikidza neriser yefirita rinonyudzwa. Triethylene glycol yakagadziriswazve inopinzwa pamusoro peabsorber kuti ibatane zvizere negasi rechisikigo riri pasi-kumusoro riri paabsorber kuti ifambiswe uye ichinjwe kuti ibvise mvura. Gasi rechisikigo rinobviswa hunyoro rinobviswa netower top mist catcher kweanopfuura 5 μm glycol drops kubva mushongwe.
Mushure mekubuda mushongwe, inochinjana kupisa nehot lean glycol isati yapinda mushongwe kuburikidza necasing heat exchanger kuderedza tembiricha yetriethylene glycol inopinda mushongwe. Gasi rechisikigo mushure mekuchinjana kupisa rinopinda mufirita rinoparadzanisa glycol inotorwa uye robva rapinda mupombi yekuburitsa kunze. Triethylene glycol yakapfuma inonwisa mvura iri mugasi rechisikigo inobuda mushongwe inonyudza uye inopinda muvharuvhu inotonga huwandu hwemvura. Mushure mekudzikamisa kumanikidzwa, inopinda muplate yekutonhodza ye reflux iri pamusoro pekoramu ine rich liquid distillation, inochinjana kupisa nemhepo inopisa inogadzirwa mu reboiler, inopa kugona kwekutonhodza kwe reflux pamusoro pekoramu, inopiswa kusvika pa50 ℃, uye pombi yekubuda inopinda mu triethylene glycol flash tank. Glycol yakapfuma inoderedzwa kumanikidzwa kusvika pa0.4MPa ~ 0.6MPa muflash tank, uye hydrocarbon gas nemamwe magasi akanyungudutswa mu triethylene glycol anoburitswa, ayo anoshandiswa segasi remafuta pakupisa reboiler.
Triethylene glycol ine simba guru inopinda mufirita yemakanika kuti isefe tsvina yemakanika, uye yobva yapinda mufirita yekabhoni yakakangwa kuti iwedzere kunyungudutsa mahydrocarbon akanyungudutswa mutriethylene glycol nezvinhu zvinoora zvetriethylene glycol. Zvadaro inopinda muplate ine simba guru uye isina simba rekuchinjana kupisa kuti ichinje kupisa netriethylene glycol ine simba guru kubva mutangi rekuchinjana kupisa riri pasi petriethylene glycol reboiler. Kuchinjana kupisa kunokwira kusvika 120 ~ 130 ℃ uye kunopinda mukoramu ine simba re distillation yemvura.
Mu triethylene glycol reboiler iri pasi pe distillation column, triethylene glycol inopiswa kusvika 193 ℃, uye mvura iri mu triethylene glycol inopatsanurwa uye inoburitswa kubva pamusoro pe distillation column kuburikidza ne fractionation ye distillation column. Lean glycol ine concentration inosvika 99% (WT) inozadza kubva mu lean liquid stripping column mu reboiler kuenda ku lower triethylene glycol heat exchange buffer tank. Pasi pesimba remhepo yakaoma mu lean liquid stripping column, concentration ye lean glycol inopinda mu heat exchange buffer tank inogona kusvika 99.5% ~ 99.8%.
Mutangi reglycol buffer, lean glycol ine tembiricha inosvika 193 ℃ inopinda mu glycol heat exchanger yakapfuma uye isina kunaka kuti ichinje kupisa ne glycol yakapfuma. Kana tembiricha yaderera kusvika pa100 ℃, inopinda mupombi. Lean triethylene glycol inopombwa mu gas-liquid heat exchanger iri kunze kwe absorber nepombi, yotonhodzwa ne outlet gas heat exchanger, yozopinda pamusoro pe absorber kubva kumusoro kwe casing kuti ipedzise solvent circulation.
Rukova rwegasi rakaoma runoburitswa kubva muchikamu chepombi yegasi rakaoma panobuda chinhu chinonyudza gasi uye runopinda mupombi yekupisa gasi rakaoma yetangi rekuchinjana kwekupisa riri pasi pe triethylene glycol reboiler. Mushure mekupiswa ne lean triethylene glycol, rinodhonzwa kusvika ku 0.4MPa kuburikidza nevharuvhu rinozvishandira roga uye rinopinda mutangi re fuel gas buffer. Mushure mekubuda mutangi re fuel gas buffer, rinokamurwa kuita nzira mbiri. Imwe nzira inopiswa uye inopinda muchikamu chezasi che lean liquid stripping column se lean liquid stripping gas; Imwe i gasi re fuel rinoshandiswa se reboiler.
