Izizathu zokungasebenzi kwesihluzo se-molecular kwinkqubo yokucoca iyunithi yokwahlula umoya

1, impembelelo yomthamo wamanzi amaninzi kumsebenzi wokuhluza we-molecular
Umsebenzi ophambili wesicoci seyunithi yokwahlukanisa umoya kukususa umswakama kunye nomxholo we-hydrocarbon emoyeni ukuze kubonelelwe ngomoya owomileyo kwiinkqubo ezilandelayo. Ulwakhiwo lwezixhobo lukwimo yebhedi ethe tyaba, ukuphakama kokuzalisa kwe-alumina esebenzayo esezantsi yi-590 mm, ukuphakama kokuzalisa kwe-molecular seeve ye-13X ephezulu yi-962 mm, kwaye izicoci ezimbini zitshintshiselwana. Phakathi kwazo, i-alumina esebenzayo ifunxa amanzi emoyeni, kwaye isihluzo se-molecular sisebenzisa umgaqo wayo wokukhetha i-molecule ukufunxa ii-hydrocarbon. Ngokusekelwe kulwakhiwo lwezinto kunye neempawu zokufunxa ze-molecular seeve, ulungelelwaniso lokufunxa luthi: H2O> H2S> NH3> SO2 > CO2(ulandelelwano lokufunxa iigesi ze-alkaline). H2O> C3H6> C2H2> C2H4, CO2, C3H8> C2H6> CH4(ulandelelwano lokufunxa ii-hydrocarbon). Kuyabonakala ukuba inamandla kakhulu ekufunxeni ii-molecule zamanzi. Nangona kunjalo, umxholo wamanzi kwisihluzo semolekyuli uphezulu kakhulu, kwaye amanzi akhululekileyo aya kwenza i-crystallization yamanzi ngesihluzo semolekyuli. Ubushushu (220 °C) obunikezelwa ngumphunga we-2.5MPa osetyenziselwa ukuhlaziya ubushushu obuphezulu abukwazi ukususa le nxalenye yamanzi ekristale, kwaye ubungakanani be-pore yesihluzo semolekyuli buhlala kwiimolekyuli zamanzi ekristale, ngoko ke abunakuqhubeka nokufunxa ii-hydrocarbons. Ngenxa yoko, isihluzo semolekyuli siyacinywa, ubomi benkonzo bufutshane, kwaye iimolekyuli zamanzi zingena kwi-low-pressure plate heat exchanger yenkqubo yokulungisa, nto leyo ebangela ukuba i-flow channel ye-heat exchanger iqine kwaye ivale, nto leyo echaphazela i-airflow channel kunye ne-heat transfer effect ye-heat exchanger, kwaye kwiimeko ezinzima, isixhobo asikwazi ukusebenza ngokuqhelekileyo.
2. Impembelelo ye-H2S kunye ne-SO2 kumsebenzi wesihluzo se-molecular
Ngenxa yokufunxwa okukhethiweyo kwesihluzo semolekyuli, ukongeza ekufunxweni kwayo okuphezulu kweemolekyuli zamanzi, ukufana kwayo neH2S kunye neSO2 kukwangcono kunokusebenza kwayo kokufunxwa kweCO2. I-H2S kunye neSO2 zihlala kumphezulu osebenzayo wesihluzo semolekyuli, kwaye izinto ezine-asidi zisabela kwisihluzo semolekyuli, nto leyo eya kubangela ukuba isihluzo semolekyuli sityhefwe kwaye singasebenzi, kwaye amandla okufunxwa kwesihluzo semolekyuli aya kuncipha. Ubomi benkonzo yesihluzo semolekyuli bufutshane.
Ngamafutshane, umxholo wokufuma ogqithisileyo, umxholo wegesi we-H2S kunye ne-SO2 emoyeni ophumayo wenqaba yokupholisa umoya yokwahlulwa komoya sesona sizathu siphambili sokungasebenzi kwesihluzo seemolekyuli kunye nokunciphisa ubomi benkonzo. Ngokulawula ngokungqongqo izalathisi zenkqubo, ukongezwa kwesihluzi sokukhupha umswakama, ukukhetha ngokufanelekileyo iintlobo zefungi, umthamo we-fungicide ngexesha elifanelekileyo, inqaba yokupholisa amanzi ukuze yongezwe amanzi aluhlaza, uhlalutyo oluqhelekileyo lwesampulu yokuvuza kwesitshintshi sobushushu kunye nezinye iindlela, ukusebenza ngokukhuselekileyo nangokuzinzileyo kwesihluzi kunokudlala indima yokuchonga ngexesha elifanelekileyo, isilumkiso ngexesha elifanelekileyo, iinjongo zokulungisa ngexesha elifanelekileyo, ubukhulu becala ukuqinisekisa ukusetyenziswa kokusebenza kakuhle kwesihluzo seemolekyuli.
