Air Seperation Unit (ASU)

Kufotokozera Kwachidule:

Air kupatukana unit ndi mtundu wa zida zimene zimatenga mpweya monga zopangira, n'kumusandutsa madzi madzi ndi compressed ndi kuziziritsa kwa kutentha cryogenic, ndiyeno pang'onopang'ono analekanitsa mpweya, nayitrogeni, argon kapena zinthu zina zamadzimadzi ku mpweya wamadzimadzi ndi rectification. .Malinga ndi zosowa za ogwiritsa ntchito, zopangidwa ndi mayunitsi olekanitsa mpweya zimatha kukhala zinthu zamtundu umodzi kapena zingapo nthawi imodzi, zomwe zimatha kukhala gasi kapena madzi.

Air kupatukana unit ndi mtundu wa zida zimene zimatenga mpweya monga zopangira, n'kumusandutsa madzi madzi ndi compressed ndi kuziziritsa kwa kutentha cryogenic, ndiyeno pang'onopang'ono analekanitsa mpweya, nayitrogeni, argon kapena zinthu zina zamadzimadzi ku mpweya wamadzimadzi ndi rectification. .Malinga ndi zosowa za ogwiritsa ntchito, zomwe zimapangidwa ndi mayunitsi olekanitsa mpweya zimatha kukhala chimodzi kapena zingapo nthawi imodzi, zomwe zimatha kukhala gasi kapena madzi.

Njira yeniyeni (kuponderezedwa kwakunja) ndi: mpweya woponderezedwa kuchokera ku mpweya wa compressor, mutachotsa zonyansa monga chinyezi, carbon dioxide, hydrocarbons ndi zonyansa zina kupyolera mu sieve ya maselo, zimatumizidwa mwachindunji kumtunda wa distillation, ndipo gawo lina limalowa. expander.Pambuyo pakukula, mpweya wa cryogenic umatumizidwa kumunsi.Mwa kukonza, nayitrogeni imatha kupezeka pamwamba pa chigawo chapamwamba ndi mpweya pansi pa gawo lapamwamba.Mpweya wolekanitsidwa wa oxygen, nayitrogeni ndi mpweya wotulutsa mpweya umatenthedwanso ndi chotenthetsera chachikulu ndikutuluka mubokosi lozizira.Zinthu za oxygen kapena nayitrogeni zomwe zimatuluka m'bokosi lozizira zimapanikizidwa ndi ma compressor kupsinjika komwe kumanenedwa ndikutumizidwa kwa wogwiritsa ntchito.

Ubwino wake

1. Mapulogalamu apamwamba owerengera ntchito omwe amatumizidwa kuchokera kunja amagwiritsidwa ntchito kukhathamiritsa ndi kusanthula ndondomeko ya zipangizozi kuti zitsimikizire kuti zili ndi zizindikiro zabwino kwambiri zaumisiri ndi zachuma komanso chiŵerengero chamtengo wapatali cha ntchito.

2. Chigawo cholekanitsa mpweya (chinthu chachikulu O₂) imatenga mpweya wabwino kwambiri wa condensation evaporator ndi kukakamiza kutuluka kwa madzi olowera m'munsi mwa madzi a mpweya, kulola mpweya wochuluka wa okosijeni kuti ukakamizidwe kuti ukhale nthunzi ndi kutuluka kuchokera pansi kupita pamwamba mu evaporator ya condensation, kupewa hydrocarbon kudzikundikira.

3. Kuonetsetsa chitetezo ndi kudalirika kwa zipangizo, zombo zonse zokakamiza, kupopera kwapaipi ndi kupanikizika kwa zigawo za ASU zimakonzedwa mosamalitsa, zopangidwa ndi kufufuzidwa motsatira malamulo a dziko.Bokosi lozizira la ASU ndi mapaipi mubokosi lozizira adutsa kuwerengera mphamvu.

Ubwino Wina

Ambiri mwa mainjiniya omwe ali pagulu laukadaulo la kampaniyo apanga mapangidwe ambiri a ASU a cryogenic kumakampani apadziko lonse lapansi komanso makampani amafuta apanyumba.

Podziwa zambiri pakupanga kwa ASU ndi kachitidwe ka polojekiti, titha kupereka majenereta a nayitrogeni (300 Nm³/h–60,000 Nm³/ h), ma ASU ang'onoang'ono (1000 Nm³/h–10,000 Nm³/h), ndi ma ASU akulu (20,000 Nm3/h–60,000 Nm³/h).
