1, umphumela wokuqukethwe kwamanzi ngokweqile emsebenzini wesihlungo sama-molecule
Umsebenzi oyinhloko wesihlanzi seyunithi yokuhlukanisa umoya ukususa umswakama kanye nokuqukethwe kwe-hydrocarbon emoyeni ukuze kuhlinzekwe umoya owomile ezinhlelweni ezilandelayo. Isakhiwo semishini sisesimweni sombhede ovundlile, ukuphakama kokugcwalisa kwe-alumina okusebenzayo okuphansi kungu-590 mm, ukuphakama kokugcwalisa kwe-molecule yesihlungo esingu-13X kungu-962 mm, kanti izihlanzi ezimbili zishintshaniswa. Phakathi kwazo, i-alumina esebenzayo imunca amanzi emoyeni, kanti isihlungo sama-molecule sisebenzisa isimiso sayo sokukhetha i-adsorption yama-molecule ukuze imunce ama-hydrocarbon. Ngokusekelwe ekwakhiweni kwezinto kanye nezakhiwo ze-adsorption yesihlungo sama-molecule, i-adsorption i-oda le-adsorption yileli: H2O> H2S> NH3> SO2 > CO2(i-oda le-adsorption yamagesi e-alkaline). H2O> C3H6> C2H2> C2H4, CO2, C3H8> C2H6> CH4(i-oda le-adsorption yama-hydrocarbon). Kungabonakala ukuthi inamandla kakhulu e-adsorption yama-molecule amanzi. Kodwa-ke, okuqukethwe kwamanzi esisefweni sama-molecule kuphakeme kakhulu, futhi amanzi akhululekile azokwakha ukwakheka kwamanzi ngesisefo sama-molecule. Izinga lokushisa (220 °C) elinikezwa umusi we-2.5MPa osetshenziselwa ukuvuselelwa kwezinga lokushisa eliphezulu alikwazi ukususa le ngxenye yamanzi ekristalu, futhi usayizi wembobo yesisefo sama-molecule uhlala ama-molecule amanzi ekristalu, ngakho-ke awakwazi ukuqhubeka nokumunca ama-hydrocarbon. Ngenxa yalokho, isisefo sama-molecule siyavalwa, impilo yenkonzo iyafinyezwa, futhi ama-molecule amanzi angena ku-heat exchanger yepuleti ephansi yohlelo lokulungisa, okwenza isiteshi sokugeleza kwesisefo sokushisa siqine futhi sivimbe, kuthinte isiteshi sokugeleza komoya kanye nomphumela wokudlulisa ukushisa kwesisefo sokushisa, futhi ezimweni ezimbi kakhulu, idivayisi ayikwazi ukusebenza ngokujwayelekile.
2. Umphumela we-H2S kanye ne-SO2 emsebenzini wesihlungo sama-molecule
Ngenxa yokumuncwa okukhethiwe kwesihlungi sama-molecule, ngaphezu kokumuncwa okuphezulu kwama-molecule amanzi, ukufana kwayo ne-H2S ne-SO2 nakho kungcono kunokusebenza kwayo kokumuncwa kwe-CO2. I-H2S ne-SO2 zihlala endaweni esebenzayo yesihlungi sama-molecule, futhi izingxenye ze-acidic zisabela ngesihlungi sama-molecule, okuzobangela ukuthi isihlungi sama-molecule sibe nobuthi futhi singasebenzi, futhi amandla okumuncwa kwesihlungi sama-molecule azoncipha. Isikhathi senkonzo yesihlungi sama-molecule siyafinyezwa.
Ngamafuphi, okuqukethwe umswakama okweqile, okuqukethwe yigesi ye-H2S kanye ne-SO2 emoyeni ophumayo wombhoshongo wokupholisa umoya ohlukanisayo yisona sizathu esiyinhloko sokungasebenzi kwesihlungo sama-molecule kanye nokufinyezwa kokuphila kwenkonzo. Ngokulawula okuqinile izinkomba zenqubo, ukungezwa kwesihlaziyi somswakama wokuphuma kwesihlanzi, ukukhetha okunengqondo kwezinhlobo ze-fungicide, umthamo we-fungicide ofanele ngesikhathi esifanele, umbhoshongo wokupholisa amanzi ukuze wengeze amanzi aluhlaza, ukuhlaziywa okuvamile kokusampula kokuvuza kwe-heat exchanger nezinye izinyathelo, ukusebenza okuphephile nokuzinzile kwesihlanzi kungadlala ukutholwa ngesikhathi, isixwayiso ngesikhathi, izinjongo zokulungisa ngesikhathi, ngezinga elikhulu ukuqinisekisa ukusetshenziswa kahle kwesihlungo sama-molecule.
