Isingeniso
Isisefo samangqamuzana esisetshenziswa segesi yemvelo esimnandi (i-desulfurization) skid, esibuye sibizwe ngokuthi ukususwa kwe-molecular sieve sulfide kusuka kugesi yemvelo , iyithuluzi eliyinhloko ekukhishweni kwe-H2S kugesi yemvelo kanye nokwelashwa kwegesi yemvelo.
Ukugeleza kwenqubo
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 ushiselwa kancane kancane ube ngu-272 ℃ ngokusebenzisa umbhoshongo we-molecular sieve desulfurization oqede inqubo yokukhangisa kusukela phansi kuya phezulu, ukuze amanzi ne-mercaptan adsorbed kusihlungi se-molecular can. zihlukaniswe futhi zibe igesi ecebile yokuvuselela ukuze kuphothulwe inqubo yokuvuselela.
Ngemuva kombhoshongo wokuvuselela, igesi ecebile yokuvuselela ingena ku-condenser yegesi yokuvuselela futhi iphole cishe ku-50 ℃, ukuze amanzi amaningi apholile, bese ehlukaniswa yisihlukanisi, futhi igesi ehlukanisiwe yokuvuselela kabusha ecebile iyashiswa.
I-molecular sieve tower idinga ukupholiswa ngemva kokuvuselelwa. Ukuze ululame ngokugcwele futhi usebenzise amandla okushisa, igesi yokuvuselela iqala ukusetshenziswa njengegesi evunguzayo ebandayo, futhi umbhoshongo upholiswa cishe ku-50 ℃ ukusuka phezulu kuye phansi ngokusebenzisa umbhoshongo we-molecular sieve desulfurization oqede inqubo yokuvuselela. Ngesikhathi esifanayo, ishisa ngokwayo. Igesi ephephethayo ebandayo ithunyelwa ngaphandle kombhoshongo wokupholisa bese ifakwa esithandweni sokushisa igesi sokuvuselela ukuze sishiswe. Ngemva kokufudumeza, umbhoshongo we-molecular sieve desulfurization uvuselelwa njengegesi yokuvuselela ethambile. Idivayisi ishintsha njalo ngamahora angu-8.
