Midziyo yekusefa yeMolecular seeve natural gas (desulfurization) skid, inonziwo molecular seeve sulfide removal kubva mugasi rechisikigo, chinhu chakakosha mukubvisa H2S kubva mugasi rechisikigo uye kurapwa kwegasi rechisikigo.
Kuyerera kwemaitiro
Chigadziko ichi chinoshandisa nzira nhatu dzemashongwe, imwe chete yekunyungudutsa shongwe, imwe chete yekumutsiridza shongwe uye imwe chete yekutonhodza shongwe. Mushure mekubvisa mvura yehydrocarbon yakaputirwa kuburikidza neseparator yefiriji yegesi, gasi rekudya rinopinda mudura redesulfurization remolecular sieve. Mvura nemercaptan mugasi rekudya zvinonyungudutswa nemolecular sieve kuti zviite kuti mvura ipere uye mercaptan adsorption ipere. Gasi rakacheneswa kubva mukushaya mvura uye kubviswa kwemercaptan rinopinda mufiriji yeguruva regesi rechigadzirwa kuti ribvise guruva resiriji remolecular, uye rinozotumirwa kunze kwenyika segasi rechigadzirwa.
Masefa emamorekuru anofanira kugadzikiswa mushure mekunyudza huwandu hwakati hwemvura nemercaptan. Mushure mekusefa guruva regasi rechigadzirwa, chikamu chegasi rechigadzirwa chinoburitswa segasi rekugadzirisa. Mushure mekunge gasi rapiswa kusvika 300 ℃ nechoto chinodziya, shongwe inodziiswa zvishoma nezvishoma kusvika 272 ℃ kuburikidza neshongwe yedesulfurization yemolecular sieve iyo yapedza maitiro ekunyudza kubva pasi kusvika kumusoro, kuitira kuti mvura nemercaptan zvakanyudzwa pasefa yemamorekuru zvigone kuparadzaniswa uye zvive gasi rekugadzirisa rakapfuma kuti kupedzisa maitiro ekugadzirisa.
Mushure mekugadzirisazve, gasi rekugadzirisazve rakapfuma rinopinda mu regeneration gas condenser rotonhorera kusvika pa50 ℃, zvekuti mvura zhinji inotonhorera, yobva yaparadzaniswa nemuchina wekuparadzanisa, uye gasi rekugadzirisazve rakapfuma rinopiswa.
Nhare yekusefa yemolecular inofanira kutonhodzwa mushure mekudzoreredzwa. Kuti idzorerwe zvizere uye ishandise simba rekupisa, gasi rekugadzirisa rinotanga rashandiswa segasi rinotonhorera rinofefetera, uye nhare inotonhodzwa kusvika pa50 ℃ kubva kumusoro kusvika pasi kuburikidza nenhare yekusefa yemolecular iyo yapedza maitiro ekugadzirisa. Panguva imwe chete, inopiswa yoga. Gasi rinotonhorera rinotumirwa kubva munhare yekutonhorera robva raiswa muchoto chekupisa chegasi rekugadzirisa kuti ridziyirwe. Mushure mekudziya, nhare yekusefa yemolecular sieve inozodzokororwa segasi rekugadzirisa risina simba. Mudziyo unochinja maawa masere ega ega.
