Ngokuthuthuka komphakathi wethu, sikhuthaza amandla ahlanzekile, ngakho isidingo segesi yemvelo njengamandla ahlanzekile siyakhula. Kodwa-ke, ngesikhathi sokuxhashazwa kwegesi yemvelo, imithombo eminingi yegesi ivame ukuba ne-hydrogen sulfide, ezodala ukugqwala kwemishini namapayipi, ingcolise imvelo futhi ibeke engozini impilo yabantu. Ngokuthuthukiswa kwesayensi nobuchwepheshe, Ukusetshenziswa okubanzi kobuchwepheshe begesi yemvelo desulfurization kuye kwaxazulula lezi zinkinga, kodwa ngesikhathi esifanayo, izindleko zokuhlanzwa kwegesi yemvelo kanye nokwelashwa kuye kwanda ngokufanele.
Isimiso
I-molecular sieve desulphurization (ebuye ibizwe ngokuthi i-desulfurization) i-skid, ebizwa nangokuthi i-molecular sieve sweeting skid, iyithuluzi eliyinhloko ekuhlanzeni igesi yemvelo noma iphrojekthi yokubeka isimo segesi yemvelo.
Isisefo samangqamuzana i-alkali metal aluminosilicate crystal enesakhiwo samathambo kanye nesakhiwo esifanayo se-microporous. I-adsorbent esebenza kahle kakhulu, umthamo ophezulu we-adsorption kanye nokukhetha kwe-adsorption. Okokuqala, kuneziteshi eziningi ezinobukhulu obufanayo be-pore kanye nezimbobo ezihlelwe kahle esakhiweni se-molecular sieve, esingahlinzeki nje indawo enkulu kakhulu, kodwa futhi ikhawulela ukungena kwama-molecule amakhulu kunezimbobo; Okwesibili, ingaphezulu le-molecular sieve ine-polarity ephezulu ngenxa yezimpawu ze-ionic lattice, ngakho-ke inamandla okukhangisa aphezulu kuma-molecule angenayo i-unsaturated, ama-molecule e-polar kanye nama-molecule e-polarizable. Amanzi ne-hydrogen sulfide ama-molecule asezindaweni ezishisayo, futhi ububanzi be-molecule buncane kunobubanzi bembotshana yesisefo samangqamuzana. Lapho igesi eluhlaza equkethe amanzi okulandela umkhondo idlula embhedeni we-sieve yamangqamuzana ekamelweni lokushisa, ukulandelela amanzi kanye ne-hydrogen sulfide kuyamuncwa, Ngakho-ke, okuqukethwe kwamanzi ne-hydrogen sulfide egesini yokudla kuyancishiswa, futhi inhloso yokuphelelwa amanzi emzimbeni kanye ne-desulfurization iyafezeka. Inqubo ye-adsorption ye-molecular sieve ihlanganisa ukufiphala kwe-capillary kanye nokukhanga ngokomzimba okubangelwa amandla e-van der Waals .Ngokwezibalo zika-Kelvin, ukufingqa kwe-capillary kuncipha ngokunyuka kwezinga lokushisa, kuyilapho ukunyuswa komzimba kuyinqubo ye-exothermic, futhi ukuminyana kwakho kwehla ngokunyuka kwezinga lokushisa. futhi iyanda ngokunyuka kwengcindezi; Ngakho-ke, inqubo ye-adsorption ye-sieve yamangqamuzana ivame ukuqhutshwa ekushiseni okuphansi nokucindezela okukhulu, kuyilapho ukuvuselelwa kokuhlaziya kwenziwa ekushiseni okuphezulu nokunciphisa ukucindezela. Ngaphansi kwesenzo sokushisa okuphezulu, igesi ehlanzekile futhi ephansi yokuvuselela igesi, i-adsorbent ye-molecular sieve ikhulula i-adsorbate ku-micropore ekugelezeni kwegesi yokuvuselela kuze kube yilapho inani le-adsorbate ku-adsorbent lifinyelela ezingeni eliphansi kakhulu. Futhi inamandla okukhangisa amanzi kanye ne-hydrogen sulfide kusuka kugesi lokuphakelayo, ibona ukuvuselelwa kanye nenqubo yokuvuselela kabusha yesisefo.
