Isivimbo se-molecular desulphurization skid

Isimiso

I-molecular sieve desulphurization (desulfurization) skid, ebizwa nangokuthi i-molecular sieve sweeting skid, iyithuluzi elibalulekile ekuhlanzeni igesi yemvelo noma ekulungiseni igesi yemvelo. I-molecular sieve iyikristalu ye-alkali metal aluminosilicate enesakhiwo sohlaka kanye nesakhiwo esifanayo se-microporous. Lapho igesi lokuphakelayo eliqukethe amanzi angaphansi lidlula embhedeni wesivingo se-molecular ekushiseni kwegumbi, amanzi angaphansi kanye ne-mercaptan kuyamuncwa, ngaleyo ndlela kunciphisa amanzi kanye nokuqukethwe kwe-mercaptan kugesi lokuphakelayo, kufezeke injongo yokuphelelwa amanzi emzimbeni kanye nokukhishwa kwe-sulfurization. Inqubo yokumuncwa kwesivingo se-molecular ifaka phakathi ukuminyana kwe-capillary kanye nokumuncwa ngokomzimba okubangelwa amandla e-van der Waals. Kusukela ku-Kelvin equation, kungabonakala ukuthi ukuminyana kwe-capillary kuyabuthaka ngokwanda kwezinga lokushisa, kuyilapho ukumuncwa ngokomzimba kuyinqubo engaphandle, futhi ukumuncwa kwayo kuyabuthaka ngokwanda kwezinga lokushisa futhi kwanda ngokwanda kwengcindezi; ngakho-ke, inqubo yokumuncwa kwesivingo se-molecular sieve ivame ukwenziwa ekushiseni okuphansi kanye nokucindezela okuphezulu, kuyilapho ukuvuselelwa kokumuncwa kwenziwa ekushiseni okuphezulu kanye nokucindezela okuphansi. Ngaphansi kwesenzo segesi yokuvuselela esezingeni lokushisa eliphezulu, ehlanzekile nephansi, i-molecule sieve adsorbent ikhipha i-adsorbate ku-micropore iye ekugelezeni kwegesi yokuvuselela kuze kube yilapho inani le-adsorbate ku-adsorbent lifinyelela ezingeni eliphansi kakhulu, futhi linamandla okumunca amanzi ne-mercaptan kusuka kugesi yokuphakelayo, liqaphela inqubo yokuvuselela nokuvuselela yesisefo sama-molecule.

Inqubo yobuchwepheshe

Ukugeleza kwenqubo yegesi yemvelo i-molecular sieve desulphurization (desulfurization) skid kuboniswe kumdwebo. Iyunithi isebenzisa inqubo emithathu yemibhoshongo, eyodwa yokumuncwa kombhoshongo, eyodwa yokuvuselelwa kombhoshongo kanye nokupholisa umbhoshongo. Ngemva kokususa uketshezi lwe-hydrocarbon olufakwe ngaphakathi ngesihlukanisi sesihlungi segesi yokuphakelayo, igesi yokuphakelayo ingena embhoshongweni wokumuncwa kombhoshongo we-molecular sieve. Amanzi kanye ne-mercaptan kugesi yokuphakelayo kudonswa yi-molecular sieve ukuze kufezwe inqubo yokumuncwa kombhoshongo kanye ne-mercaptan. Igesi ehlanziwe ekudonsweni kombhoshongo kanye nokususwa kwe-mercaptan ingena kusihlungi sothuli lwegesi yomkhiqizo ukuze kususwe uthuli lwesihlungi se-molecular, bese ithunyelwa ngaphandle njengegesi yomkhiqizo.

Izisefo zama-molecule zidinga ukuvuselelwa ngemva kokumunca inani elithile lamanzi kanye ne-mercaptan. Ngemva kokuhlunga uthuli lwegesi lomkhiqizo, ingxenye yegesi yomkhiqizo ikhishwa njengegesi yokuvuselela. Ngemva kokuba igesi ishiswe ku-300 ℃ ngesithando sokushisa, umbhoshongo ushiswa kancane kancane ku-272 ℃ ngokusebenzisa umbhoshongo wokususa i-sulfurization wesisefo sama-molecule osuqede inqubo yokumunca kusukela phansi kuya phezulu, ukuze amanzi kanye ne-mercaptan efakwe kusisefo sama-molecule kungahlukaniswa futhi kube yigesi yokuvuselela ecebile ukuze kuqedwe inqubo yokuvuselela.
