Ka nts'etsopele ea sechaba sa rona, re buella matla a hloekileng, kahoo tlhokahalo ea khase ea tlhaho e le matla a hloekileng le eona e ntse e eketseha. Leha ho le joalo, ha ho ntse ho sebelisoa khase ea tlhaho, liliba tse ngata tsa khase hangata li na le hydrogen sulfide, e tla baka ho bola ha thepa le liphaephe, e silafatse tikoloho le ho beha bophelo ba batho kotsing. Ka tsoelo-pele ea saense le thekenoloji, Tšebeliso e pharaletseng ea theknoloji ea khase ea tlhaho ea desulfurization e rarollotse mathata ana, empa ka nako e ts'oanang, litšenyehelo tsa tlhoekiso ea khase ea tlhaho le phekolo li eketsehile ka tsela e nepahetseng.

Molecular sieve desulphurization (eo hape e bitsoang desulfurization) skid, eo hape e bitsoang molecular sieve sweeting skid, ke sesebelisoa sa bohlokoa sa ho hloekisa khase ea tlhaho kapa morero oa ho lokisa khase ea tlhaho.

Sieve ea molek'hule ke kristale ea alkali ea tšepe ea aluminosilicate e nang le sebopeho sa skeleton le sebopeho sa microporous se tšoanang. Ke adsorbent e nang le ts'ebetso e ntle haholo, bokhoni bo phahameng ba papatso le khetho ea adsorption. Ntlha ea pele, ho na le likanale tse ngata tse nang le boholo bo lekanang ba pore le masoba a hlophisitsoeng ka makhethe mohahong oa sieve oa limolek'hule, o sa faneng feela ka sebaka se seholo haholo, empa hape o fokotsa ho kena ha limolek'hule tse kholo ho feta masoba; Taba ea bobeli, bokaholimo ba sieve ea limolek'hule bo na le polarity e phahameng ka lebaka la litšoaneleho tsa lattice ea ionic, ka hona, e na le matla a holimo a adsorption bakeng sa limolek'hule tse unsaturated, limolek'hule tsa polar le limolek'hule tse polarization. Metsi le hydrogen sulfide ke limolek'hule tsa polar, 'me bophara ba molek'hule bo nyane ho feta bophara ba pore ea sieve ea molek'hule. Ha khase e tala e nang le metsi a marang-rang e feta betheng ea limolek'hule ka mocheso oa kamore, ho kenngoa metsi le hydrogen sulfide, kahoo, litaba tsa metsi le hydrogen sulfide ka khase ea phepelo li fokotsehile, 'me morero oa ho felloa ke metsi le desulfurization oa phethahala. The adsorption process of molecular sieve e kenyelletsa capillary condensation le adsorption ea 'mele e bakoang ke matla a van der Waals.Ho ea ka Kelvin equation, capillary condensation e fokotseha ka ho eketseha ha mocheso, athe adsorption ea' mele ke mokhoa oa exothermic, 'me ho kenngoa ha eona ho fokotseha ka ho eketseha ha mocheso. le ho eketseha ka ho eketseha ha khatello; Ka hona, ts'ebetso ea adsorption ea sieve ea molek'hule e atisa ho etsoa ka mocheso o tlase le khatello e phahameng, ha ho tsosolosoa ha tlhahlobo ho etsoa ka mocheso o phahameng le khatello e fokotsehileng. Tlas'a ketso ea mocheso o phahameng, khase e hloekileng le e tlaase ea ho tsosolosa khatello, molecular sieve adsorbent e lokolla adsorbate ka micropore ho phallo ea khase ea tsosoloso ho fihlela palo ea adsorbate ho adsorbent e fihla boemong bo tlaase haholo. E boetse e na le bokhoni ba ho adsorb metsi le hydrogen sulfide ho tloha khase ea phepelo, ho hlokomela ts'ebetso ea ho nchafatsa le ho e sebelisa hape ea sieve.

Phallo ea ts'ebetso e bontšoa setšoantšong. Sehlopha se amohela mekhoa e meraro ea tora, tora e le 'ngoe bakeng sa adsorption, tora e le' ngoe bakeng sa tsosoloso le tora e le 'ngoe bakeng sa ho pholisa. karohano ea coalescence, ebe e kena ka molek'hule sieve desulfurization tower a-801, a-802 le-803. Metsi le hydrogen sulfide ka khase ea phepelo li adsorbed ke sieve ea molek'hule ho hlokomela dehydration le hydrogen sulfide adsorption process.The khase e hloekisitsoeng bakeng sa dehydration le hydrogen sulfide tloswa e kena sehlahiswang sehlahiswa lerōle sefa ho tlosa molecular sieve lerōle 'me e romeloa linaheng tse ling e le khase ea lihlahisoa.

Sieve ea molek'hule e hloka ho tsosolosoa ka mor'a hore e khabise metsi a mangata le hydrogen sulfide.Karolo e 'ngoe ea khase ea sehlahisoa e ntšoa ka khase ea sehlahisoa ka mor'a ho hloekisa lerōle e le khase ea tsosoloso. Ka mor'a hore khase e futhumatsoe ho 270 ℃ ka sebōping sa ho futhumatsa, tora e futhumatsoa butle-butle ho 270 ℃ ho tloha holimo ho ea tlaase ka tora ea molecular sieve desulfurization e qetileng mokhoa oa ho bapatsa, e le hore metsi le hydrogen sulfide adsorbed holim'a sieve ea molek'hule. e ka rarolloa hore e be khase e nchafatsang le ho phethela tšebetso ea nchafatso.

Khase e ruileng e nchafatsang ka mor'a hore e tlohe toreng e nchafatsang e kena ka har'a condenser ea khase e nchafatsang hore e pholisoe hoo e ka bang 50 ℃, 'me khase ea pholisoa ebe e fanoa hloohong ea mollo.

Tora ea sieve ea molek'hule e hloka ho pholile ka mor'a ho nchafatsoa. Bakeng sa ho hlaphoheloa ka botlalo le ho sebelisa matla a mocheso, khase e nchafatsang e qala ho sebelisoa e le khase e fokang e batang, 'me tora e pholile ho fihla ho 50 ℃ ho tloha holimo ho ea tlase ka tora ea molecular sieve desulfurization e phethileng ts'ebetso ea nchafatso. Ka nako e ts'oanang, e chesa pele ka boeona. Ka mor'a hore khase e fokang e batang e tsoe ka tora e pholileng, e kena ka sebōping sa ho futhumatsa khase e nchafatsang bakeng sa ho futhumatsa, ebe e tsosolosa tora ea molecular sieve desulfurization e le khase e nchafatsang.
