Isimiso

I-Molecular sieve desulphurization (desulfurization) skid, ebizwa nangokuthi i-molecular sieve sweeting skid, iyithuluzi eliyinhloko ekuhlanzeni igesi yemvelo noma ukulungisa igesi yemvelo. Isisefo samangqamuzana i-alkali metal aluminosilicate crystal enesakhiwo sohlaka kanye nesakhiwo esifanayo se-microporous. Lapho igesi yokuphakelayo equkethe amanzi okulandela umkhondo idlula kumbhede wesisefo samangqamuzana ezingeni lokushisa legumbi, amanzi okulandela umkhondo ne-mercaptan ayamuncwa, ngaleyo ndlela kunciphisa amanzi nokuqukethwe kwe-mercaptan kugesi eliphakelayo, kuqaphela inhloso yokuphelelwa amanzi emzimbeni kanye ne-desulfurization. Inqubo yokukhangisa ye-molecular sieve ihlanganisa ukufingqa kwe-capillary kanye nokukhangiswa ngokomzimba okubangelwa amandla e-van der Waals. Kusukela ku-equation ye-Kelvin, kungabonakala ukuthi i-capillary condensation iba buthaka ngokukhuphuka kwezinga lokushisa, kuyilapho ukukhanyiswa ngokomzimba kuyinqubo ye-exothermic, futhi ukukhangisa kwayo kuba buthakathaka ngokunyuka kwezinga lokushisa futhi kukhuphuka ngokunyuka kwengcindezi; ngakho-ke, inqubo ye-adsorption ye-molecular sieve ivame ukuqhutshwa ekushiseni okuphansi nokucindezela okukhulu, kuyilapho ukuvuselelwa kwe-desorption kwenziwa ekushiseni okuphezulu nokucindezela okuphansi. 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 linamandla okumunca amanzi ne-mercaptan kusuka kugesi ophakelayo, ibona inqubo yokuvuselela i-molecular and recycling.

Inqubo yezobuchwepheshe

Ukugeleza kwenqubo yegesi yemvelo ye-molecular sieve desulphurization (desulfurization) skid kuboniswa kumdwebo. Iyunithi yamukela inqubo yemibhoshongo emithathu, i-adsorption yombhoshongo owodwa, ukuvuselelwa kombhoshongo owodwa kanye nokupholisa kombhoshongo owodwa. Ngemva kokukhipha uketshezi lwe-hydrocarbon olufakiwe ngesihlukanisi segesi sokuphakelayo, igesi yokuphakelayo ingena embhoshongweni we-molecular sieve desulfurization. Amanzi kanye ne-mercaptan kugesi ephakelayo kukhangiswa ngesisefo samangqamuzana ukuze kubonwe inqubo yokuphelelwa amanzi emzimbeni kanye ne-mercaptan adsorption. Igesi ehlanziwe kusukela ekuphelelweni amanzi emzimbeni nasekukhishweni kwe-mercaptan ingena kusihlungi sothuli lwegesi yomkhiqizo ukuze isuse uthuli lwesisefo samangqamuzana, bese ithunyelwa ngaphandle njengegesi yomkhiqizo.

Izisefo zamamolekyuli zidinga ukwenziwa kabusha ngemva kokukhangisa inani elithile lamanzi ne-mercaptan. Ngemva kokuhlunga uthuli lwegesi yomkhiqizo, ingxenye yegesi yomkhiqizo ikhishwa njengegesi yokuvuselela. Ngemuva kokuthi igesi ishiselwe ku-300 ℃ ngesithando sokushisa, umbhoshongo uyashisisa kancane kancane ube ngu-272 ℃ ngombhoshongo we-molecular sieve desulfurization oqede inqubo yokukhangisa kusukela phansi kuya phezulu, ukuze amanzi kanye ne-mercaptan adsorbed kusihlungo se-molecular can be ehlukaniswe i-regeneration ecebile futhi iqede inqubo yokuvuselela kabusha.
