Izizathu zokungasebenzi kwe-molecular sieve kwinkqubo yokucoca yeyunithi yokwahlula umoya

I-1, isiphumo somxholo wamanzi ogqithisileyo kumsebenzi we-molecular sieve
Umsebenzi oyintloko weyunithi yokucoca iyunithi yokucoca kukususa umswakama kunye nomxholo we-hydrocarbon ukusuka emoyeni ukubonelela ngomoya owomileyo kwiinkqubo ezilandelayo. Isakhiwo sesixhobo sikwimo yombhede othe tye, i-alumina esezantsi esebenzayo yokuzalisa ukuphakama yi-590 mm, i-13X ephezulu ye-molecular sieve ukuphakama yi-962 mm, kwaye abahlambululi ababini batshintshwa phakathi komnye nomnye. Phakathi kwazo, i-alumina esebenzayo ikakhulu ibhengeza amanzi emoyeni, kwaye i-molecular sieve isebenzisa umgaqo wayo wokukhetha imolekyuli yokuthengisa iihydrocarbons. Ngokusekelwe kubume bezinto eziphathekayo kunye neempawu ze-adsorption ze-molecular sieve, i-adsorption order: H2O> H2S> NH3> SO2> CO2 (umyalelo we-adsorption of alkaline gases). H2O> C3H6> C2H2> C2H4, CO2, C3H8> C2H6> CH4(umyalelo we-adsorption of hydrocarbons). Ingabonwa ukuba inokusebenza okunamandla kakhulu kwe-adsorption yeeathomu zamanzi. Nangona kunjalo, umxholo wamanzi we-molecular sieve uphezulu kakhulu, kwaye amanzi asimahla aya kwenza icrystallization yamanzi nge-molecular sieve. Iqondo lobushushu (220 °C) elinikezelwe yi-2.5MPa umphunga osetyenziselwa ukuhlaziywa kobushushu obuphezulu awukakwazi ukususa le nxalenye yamanzi ekristale, kwaye ubungakanani bepore ye-molecular sieve ihlala iimolekyuli zamanzi ekristale, ngoko ayinakuqhubeka nokubhengeza ii-hydrocarbons. Ngenxa yoko, i-sieve ye-molecular ivaliwe, ubomi benkonzo bufutshane, kwaye iimolekyuli zamanzi zingena kwi-low-pressure plate heat exchanger yenkqubo yokulungiswa, okubangela ukuba umjelo wokuhamba komtshintshi wokushisa umise kwaye uthintele, uchaphazela umzila wokuhamba komoya. kunye nefuthe lokutshintshwa kobushushu bomtshintshi wobushushu, kwaye kwiimeko ezimandundu, isixhobo asikwazi ukusebenza ngokuqhelekileyo.
2. Impembelelo ye-H2S kunye ne-SO2 kumsebenzi we-molecular sieve
Ngenxa ye-adsorption ekhethiweyo ye-molecular sieve, ukongeza kwi-adsorption ephezulu yeemolekyuli zamanzi, ubudlelwane bayo be-H2S kunye ne-SO2 bukwangcono kunokusebenza kwe-adsorption ye-CO2. I-H2S kunye ne-SO2 ithatha indawo esebenzayo ye-molecular sieve, kwaye i-acidic components isabela nge-molecular sieve, eya kubangela ukuba i-molecular sieve ibe netyhefu kwaye ingasebenzi, kwaye umthamo we-adsorption we-molecular sieve uya kuncipha. Ubomi benkonzo ye-molecular sieve bufutshane.
Isishwankathelo, ubuninzi bomswakama obuninzi, i-H2S kunye ne-SO2 ye-gas content kwi-outlet air of the air-cooling tower yokwahlukana komoya sesona sizathu sokungasebenzi kwe-molecular sieve kunye nokunciphisa ubomi benkonzo. Ngolawulo olungqongqo lwezalathisi zenkqubo, ukongezwa kwesihlalutyi sokufuma esiphuma sisicoci, ukhetho olufanelekileyo lweentlobo zefungicide, idosi yexesha elifanelekileyo lokubulala umngundo, inqaba yokupholisa amanzi ukongeza amanzi akrwada, uhlalutyo lwesampulu rhoqo lokuvuza kobushushu kunye namanye amanyathelo, ikhuselekile kwaye izinzile. ukusebenza komcoci kunokudlala ukubonwa kwangexesha, isilumkiso kwangexesha, iinjongo zohlengahlengiso kwangexesha, kumlinganiselo omkhulu wokuqinisekisa ukusetyenziswa kwe-molecular sieve esebenzayo.
