Izizathu zokungasebenzi kwe-molecular sieve kwinkqubo yokucoca yeyunithi yokwahlula umoya

I-1, isiphumo somthamo wamanzi amaninzi kumsebenzi we-molecular sieve
Umsebenzi oyintloko wokucoca iyunithi yokwahlula umoya 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 bayatshintshwa phakathi komnye nomnye.Phakathi kwazo, i-alumina evunyiweyo 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 akhululekile aya kwenza i-crystallization yamanzi kunye ne-molecular sieve.Iqondo lobushushu (220 °C) elibonelelwa yi-2.5MPa umphunga osetyenziselwa ukuhlaziywa kobushushu obuphezulu awukakwazi ukususa le nxalenye yamanzi ekristale, kwaye ubungakanani bepore ye-molecular sieve ithathwa yi-crystal water molecules, ngoko ayikwazi ukuqhubeka nokubhengeza ii-hydrocarbons.Ngenxa yoko, i-sieve ye-molecular ivaliwe, ubomi benkonzo bufutshane, kwaye iamolekyu zamanzi zingena kwi-low-pressure plate heat exchanger yenkqubo yokulungiswa, okubangela ukuba umjelo wokuhamba komtshisi wokushisa ube ngumkhenkce kwaye uvale, 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 zithatha indawo esebenzayo ye-molecular sieve, kwaye i-acidic components isabela nge-molecular sieve, eya kubangela ukuba i-molecular sieve ibe netyhefu kwaye ingasebenzi, kwaye amandla okunyusa i-molecular sieve iya kuncipha.Ubomi benkonzo ye-molecular sieve bufutshane.
Isishwankathelo, ubuninzi bomswakama obuninzi, i-H2S kunye ne-SO2 yegesi yegesi kwi-outlet air of the air air air cooling tower iyona sizathu esiyintloko 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, ukhuseleko noluzinzileyo. ukusebenza komcoci kunokudlala ukubonwa kwangexesha, isilumkiso kwangexesha, iinjongo zohlengahlengiso kwangexesha, kumlinganiselo omkhulu wokuqinisekisa ukusetyenziswa kwe-molecular sieve esebenzayo.
