Maitiro ekuunzwa kwefekitari yeTEG yekubvisa mvura mumuviri muchikamu chekurapa gasi rechisikigo
Nzira yekunyungudutsa mvura ndiyo imwe yenzira dzinonyanya kushandiswa maitiro ekubvisa mvura mumuviri muindasitiri yekugadzira gasi rechisikigo, Kupera mvura mumuviri (TEG) (triethylene glycol dehydration) inowanzo shandiswa semhando yeSolvent. Inoshandisa musimboti wekunyudzwa kwemvura uye inoshandisa zvinhu zveglycol (zvakaita setriethylene glycol) sezvinhu zvinonyudzwa kuti zvibatane zvizere negasi rechisikigo, zvichiendesa mvura kune chinhu chinonyungudutsa mvura kuti ipere.
Mushure mekubuda mushongwe, inopinda mu casing heat exchanger uye inochinjana kupisa ne hot lean glycol isati yapinda mushongwe kuderedza tembiricha ye TEG. Gasi rechisikigo mushure mekuchinjana kupisa rinopinda mu filter separator kuti riparadzanise glycol inotorwa uye robva rapinda mu outer pipeline. TEG yakapfuma yakatora hunyoro mugasi rechisikigo inobuda kubva mu absorption tower yopinda mu liquid level regulating valve, uye mushure mekudzikamisa, inopinda mu reflux cooling coil iri pamusoro pe rich liquid rectification column uye inochinjana kupisa ne hot steam inogadzirwa mu reboiler kuti ipe column top reflux. Mushure mekupa column top reflux cooling capacity, inopiswa kusvika pa50 ℃, uye yobva yabuda mu coil ichienda ku TEG flash tank. Glycol yakapfuma inoderedzwa kusvika pa 0.4mpa~0.6mpa mu flash tank, uye hydrocarbon gas nemamwe magasi akanyungudutswa mu TEG anoburitswa, uye chikamu ichi chegasi chinoshandiswa se fuel gas yekupisa reboiler.
Mvura yakapfuta TEG inopinda mufirita yemakanika kuti isefe tsvina yemakanika, uye yobva yapinda mufirita yekabhoni yakakangwa kuti iwedzere kunyungudutsa zvinhu zvehydrocarbon zvakanyungudutswa muTEG nezvinhu zvakaora zveTEG. Zvadaro inopinda muplate-type lean-rich liquid heat exchanger, yochinjana kupisa ne lean TEG yekupisa kwakanyanya kubva mutangi re heat exchange buffer riri pasi peTEG reboiler, uye yopisa kusvika ~150 °C kuti ipinde mu rich liquid rectification column.
MuTEG reboiler iri pasi pekoramu yekugadzirisa, TEG inodziiswa kusvika 193 ℃, uye mvura iri muTEG inopatsanurwa uye inoburitswa kubva pamusoro pekoramu yekugadzirisa kuburikidza nechikamu chekupatsanurwa kwekoramu yekugadzirisa. Iyo lean glycol ine huwandu hunosvika 99% (wt) inozadza kubva pakoramu yekupatsanurwa kwemvura yakatsetseka iri mureboiler kuenda kutangi repasi reTEG heat exchange buffer. Pasi pekushanda kwegasi rakaoma riri mukoramu yekupatsanurwa kwemvura yakatsetseka, huwandu hwelean glycol hunopinda mutangi reheat exchange buffer hunogona kusvika 99.5% ~ 99.8%.
Mutangi reglycol buffer, lean glycol ine tembiricha inosvika 193 °C inopinda mu lean-rich glycol heat exchanger kuti ichinje kupisa ne rich glycol, uye tembiricha inodzikira kusvika 100 °C yopinda mupombi. Lean liquid TEG inopombwa mu gas-liquid heat exchanger iri kunze kwe absorption tower, uye mushure mekutonhodza ne gas heat exchanger iri kunze kwe tower, inopinda pamusoro pe absorption tower kubva kumusoro kwe casing kuti ipedzise solvent circulation.
