Isikhindi semishini yokwenza ubumnandi ngegesi yemvelo

Isingeniso

Imishini yokwenza i-molecular sieve sweetening gas (desulfurization) skid, ebizwa nangokuthi i-molecular sieve sulfide removal from natural gas, iyithuluzi elibalulekile ekususweni kwe-H2S kusuka kugesi yemvelo kanye nokwelashwa kwegesi yemvelo.

Ukugeleza kwenqubo

Iyunithi isebenzisa inqubo emithathu yemibhoshongo, ukumuncwa kombhoshongo owodwa, ukuvuselelwa kombhoshongo owodwa kanye nokupholisa umbhoshongo owodwa. Ngemva kokususa uketshezi lwe-hydrocarbon olufakwe ngaphakathi ngesihlukanisi sesihlungi segesi yokuphakelayo, igesi yokuphakelayo ingena embhoshongweni wokususa i-sulfurization wesihlungi sama-molecule. Amanzi kanye ne-mercaptan kugesi yokuphakelayo kumoshwa ngesihlungi sama-molecule ukuze kufezwe inqubo yokuphelelwa amanzi kanye nokumuncwa kwe-mercaptan. Igesi ehlanziwe ekuphelelweni amanzi kanye nokususwa kwe-mercaptan ingena kusihlungi sothuli lwegesi yomkhiqizo ukuze kususwe uthuli lwesihlungi sama-molecule, 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.

Ngemva kombhoshongo wokuvuselela, igesi yokuvuselela ecebile ingena ku-condenser yegesi yokuvuselela bese iphola cishe ku-50 ℃, ukuze iningi lamanzi liphole, bese lihlukaniswa yisihlukanisi, bese igesi yokuvuselela ecebile ehlukanisiwe ishiswe.

Umbhoshongo wesihlungo sama-molecule udinga ukupholiswa ngemva kokuvuselelwa. Ukuze ubuyiselwe ngokugcwele futhi usebenzise amandla okushisa, igesi yokuvuselela isetshenziswa kuqala njengegesi ebandayo ephefumulayo, bese umbhoshongo upholiswa cishe ku-50 ℃ kusukela phezulu kuya phansi ngombhoshongo wokususa i-sulfurization wesihlungo sama-molecule osuqede inqubo yokuvuselelwa. Ngesikhathi esifanayo, ushiswa wodwa. Igesi ebandayo ephefumulayo ithunyelwa ngaphandle kombhoshongo wokupholisa bese ifakwa esithandweni sokushisa segesi yokuvuselela ukuze ifudumale. Ngemva kokufudumala, umbhoshongo wokususa i-sulfurization wesihlungo sama-molecule uvuselelwa njengegesi yokuvuselela engenamafutha. Idivayisi ishintsha njalo emahoreni angu-8.
