Molecular sieve natural gasi sweetening equipment (desulfurization) skid, inonziwo molecular sieve sulfide kubviswa kubva mugasi chaiwo, chinhu chakakosha pakubvisa H2S kubva mugasi rechisikigo uye kurapwa gasi.
Process flow
Iyo unit inotora matatu shongwe process, imwe shongwe adsorption, imwe shongwe yekuvandudzwa uye imwe shongwe kutonhora. Mushure mekubvisa iyo intrained hydrocarbon fluid kuburikidza neyekudya gasi sefa separator, gasi rekudya rinopinda mune molecular sieve desulfurization tower. Iyo mvura uye mercaptan mune gasi rekudya zvinoshambadzirwa neiyo molecular sieve kuona iyo dehydration uye mercaptan adsorption maitiro. Iyo gasi yakacheneswa kubva pakupererwa nemvura uye kubviswa kwe mercaptan inopinda muchigadzirwa gasi guruva sefa kuti ibvise mamorekuru sieve guruva, yozoendeswa kunze kwenyika sechigadzirwa gasi.
Masefa emolecular anoda kuvandudzwa mushure mekushambadzira imwe huwandu hwemvura uye mercaptan. Mushure mekusefa chigadzirwa chegasi guruva, chikamu chegasi chechigadzirwa chinotorwa seyakagadziridzwa gasi. Mushure mekunge gasi rapiswa kusvika 300 ℃ nechoto chekudziya, shongwe inodziiswa zvishoma nezvishoma kusvika 272 ℃ kuburikidza ne molecular sieve desulfurization tower iyo yapedza iyo adsorption process kubva pasi kusvika kumusoro, kuitira kuti mvura uye mercaptan adsorbed pane molecular sieve inogona. kupatsanurwa kunze uye kuve akapfuma regeneration gasi kupedzisa hurongwa hwekuvandudza.
Mushure meiyo shongwe yekuvandudza, iyo yakapfuma yekuvandudza gasi inopinda mune yekuvandudza gasi condenser uye inotonhorera kusvika pa50 ℃, kuitira kuti yakawanda yemvura inotonhorera, uye yozoparadzaniswa nemuparadzi, uye iyo yakaparadzaniswa yakapfuma yekuvandudza gasi inopiswa.
Iyo molecular sieve tower inoda kutonhodzwa mushure mekuvandudzwa. Kuti udzore zvizere uye ushandise simba rekupisa, gasi rekuvandudza rinotanga kushandiswa semhepo inotonhorera inofuridza, uye shongwe inotonhodzwa kusvika pa50 ℃ kubva kumusoro kusvika pasi kuburikidza nemolecular sieve desulfurization tower iyo yapedza maitiro ekuvandudza. Panguva imwecheteyo, inofarirwa pachayo. Gasi rinofefetera rinotonhora rinotumirwa kunze kweshongwe yekutonhodza robva rapinzwa muchoto chekudziisa gasi rekudziya. Mushure mekupisa, iyo molecular sieve desulfurization tower inogadzirwazve seyakaonda patsva gasi. Chishandiso chinochinja maawa masere ega ega.
