Molao-motheo

Molecular sieve desulphurization (desulfurization) skid, eo hape e bitsoang molecular sieve sweeting skid, ke sesebelisoa se ka sehloohong sa tlhoekiso ea khase ea tlhaho kapa ho lokisa khase ea tlhaho. Sieve ea molek'hule ke kristale ea alkali ea tšepe ea aluminosilicate e nang le sebopeho sa moralo le sebopeho sa microporous se ts'oanang. Ha khase ea phepelo e nang le metsi a marang-rang e feta ka har'a bethe ea sieve ea molek'hule ka mocheso oa kamore, metsi a trace le mercaptan a kenngoa, kahoo a fokotsa metsi le mercaptan ka har'a khase ea phepelo, ho lemoha morero oa ho felloa ke metsi le ho senya metsi. Ts'ebetso ea adsorption ea sieve ea limolek'hule e kenyelletsa ho phophoma ha capillary le adsorption ea 'mele e bakoang ke matla a van der Waals. Ho tloha ho Kelvin equation, ho ka bonoa hore condensation ea capillary e fokotsehile ka ho eketseha ha mocheso, ha ho khabisoa ha 'mele ke mokhoa o sa tloaelehang,' me ho khabisoa ha eona ho fokolisa ka ho eketseha ha mocheso le ho eketseha ka ho eketseha ha khatello; ka hona, mokhoa oa adsorption oa sieve ea molek'hule o atisa ho etsoa ka mocheso o tlaase le khatello e phahameng, ha ho tsosolosoa ha desorption ho etsoa ka mocheso o phahameng le khatello e tlaase. Tlas'a ketso ea mocheso o phahameng, khase e hloekileng le e tlase ea khatello ea khatello, molek'hule sieve adsorbent e lokolla adsorbate ka har'a micropore ho phallo ea khase e nchafatsang ho fihlela palo ea adsorbent e fihla boemong bo tlase haholo, 'me e na le bokhoni ba ho monya metsi le mercaptan ho tsoa khase ea phepelo, ho hlokomela ts'ebetso ea ho nchafatsa limolek'hule.

Mokhoa oa theknoloji

Ts'ebetso ea phallo ea khase ea tlhaho ea molek'hule ea sieve desulphurization (desulfurization) skid e bontšoa setšoantšong. Yuniti e amohela lits'ebetso tse tharo tsa tora, adsorption e le 'ngoe ea tora, nchafatso e le' ngoe ea tora le pholiso e le 'ngoe ea tora. Ka mor'a ho tlosa mokelikeli oa hydrocarbon o kentsoeng ka mochine o arolang sefahla sa khase, khase ea phepelo e kena tora ea molecular sieve desulfurization. Metsi le mercaptan tse ka har'a khase ea phepelo li hasoa ke sieve ea molek'hule ho hlokomela ts'ebetso ea dehydration le mercaptan adsorption. Khase e hloekisitsoeng ho tsoa ho dehydration le ho tlosoa ha mercaptan e kena ka har'a sefahla sa lerole la sehlahisoa ho tlosa lerōle la sieve ea limolek'hule, ebe e romelloa kantle ho naha e le khase ea sehlahisoa.

Li-sieve tsa limolek'hule li hloka ho tsosolosoa ka mor'a ho ba le metsi a mangata le mercaptan. Ka mor'a ho hloekisa lerōle la khase ea sehlahisoa, karolo ea khase ea sehlahisoa e ntšoa e le khase ea tsosoloso. Kamora hore khase e futhumatsoe ho 300 ℃ ke sebōpi se futhumatsang, tora e futhumatsoa hanyane ka hanyane ho 272 ℃ ka tora ea molecular sieve desulfurization e qetileng ts'ebetso ea adsorption ho tloha tlase ho ea holimo, e le hore metsi le mercaptan adsorbed holim'a sieve ea limolek'hule e ka aroloa ka mokhoa o ruileng oa ho nchafatsa.
