High Quality China Dehydration Equipment Exporters - Molecular sieve desulphurization skid - Rongteng

Principle

Molecular sieve desulphurization (desulfurization) skid, inonziwo molecular sieve sweeting skid, chinhu chakakosha mukuchenesa gasi chaiwo kana kugadzirisa gasi. Molecular sieve ndeye alkali simbi aluminosilicate crystal ine furemu chimiro uye yunifomu microporous chimiro. Kana gasi rekudya rine mvura yekutsvagisa richipfuura nepamubhedha wekusefa pane tembiricha yekamuri, iyo inoteedzera mvura uye mercaptan inonyudzwa, nekudaro ichidzikisa mvura uye mercaptan zvirimo mugasi rekudyisa, nekuona chinangwa chekubvisa mvura uye desulfurization. Iyo adsorption process ye molecular sieve inosanganisira capillary condensation uye yemuviri adsorption inokonzerwa nevan der Waals simba. Kubva kuKelvin equation, zvinogona kuonekwa kuti capillary condensation inopera nekuwedzera kwekushisa, nepo kushambadza kwemuviri kunonzi exothermic process, uye kushambadza kwayo kunopera nekuwedzera kwekushisa uye kunowedzera nekuwedzera kwekumanikidza; saka, iyo adsorption process ye molecular sieve inowanzoitwa pakadzika tembiricha uye yakanyanya kudzvanywa, nepo desorption regeneration inoitwa pakupisa kwakanyanya uye kuderera kudzvinyirira. Pasi pechiito chekushisa kwepamusoro, yakachena uye yakaderera kudzvanywa patsva gasi, iyo molecular sieve adsorbent inoburitsa adsorbate mumicropore mukuyerera kwegasi kuyerera kudzamara huwandu hweadsorbate mu adsorbent hwasvika padanho rakaderera, uye inokwanisa kutora mvura uye mercaptan kubva gasi rekudyisa, ichiziva kuvandudzwa kwema molecular uye recycling process.

Tekinoroji maitiro

Kuyerera kwegasi rechisikigo molecular sieve desulphurization (desulfurization) skid inoratidzwa mumufananidzo. 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 kupfumisa kugadzirwazve kunze uye kuve kwakapfuma kugadzirwazve.
