Nheyo
Kubvisa sulphurization (desulfurization) skid, iyo inonziwo molecular sieve sweeting skid, chinhu chakakosha mukuchenesa gasi rechisikigo kana kugadzirisa gasi rechisikigo. Molecular sieve ikristalo yealkali metal aluminosilicate ine chimiro cheframework uye chimiro chakafanana che microporous. Kana gasi rekudyisa rine mvura shoma richipfuura nepamubhedha we molecular sieve patembiricha yemumba, mvura shoma nemercaptan zvinonyudzwa, nokudaro zvichideredza mvura ne mercaptan mugasi rekudyisa, zvichiita kuti chinangwa chekushaya mvura mumuviri uye kubvisa sulfurization chive. Maitiro ekudyisa molecular sieve anosanganisira capillary condensation uye physical adsorption inokonzerwa ne van der Waals force. Kubva muKelvin equation, zvinogona kuonekwa kuti capillary condensation inoderera nekuwedzera kwetembiricha, nepo physical adsorption iri exothermic process, uye adsorption yayo inoderera nekuwedzera kwetembiricha uye inowedzera nekuwedzera kwedzvinyiriro; saka, adsorption process ye molecular sieve inowanzoitwa patembiricha yakaderera uye high pressure, nepo desorption regeneration ichiitwa patembiricha yepamusoro uye low pressure. Pasi pesimba remhepo inopisa, yakachena uye ine simba shoma, molecular see adsorbent inoburitsa adsorbate iri mu micropore ichipinda mu regeneration gas flow kusvika huwandu hwe adsorbate iri mu adsorbent hwasvika padanho rakaderera, uye hune simba rekupinza mvura ne mercaptan kubva mu feed gas, zvichiita kuti mamorekuru ese agadziriswe uye adzokororwe.
Maitiro etekinoroji
Kufamba kwemaitiro egasi rechisikigo remamorekuru ekubvisa sulphurization (desulfurization) skid kunoratidzwa mudhayagiramu. Chigadziko ichi chinoshandisa matanho matatu eshongwe, imwe chete yekudzvinyirirwa kweshongwe, imwe chete yekudzoreredza shongwe uye imwe chete yekutonhodza shongwe. Mushure mekubvisa mvura yehydrocarbon yakavharirwa kuburikidza neseparator yefiriji yegesi yekudyisa, gasi rekudyisa rinopinda mushongwe yefiriji yemasero. Mvura nemercaptan mugasi rekudyisa zvinonamirwa nesefa yemasero kuti zvionekwe kuti mvura inonaya uye maitiro ekudzvinyirirwa kwemercaptan. Gasi rakacheneswa kubva mukushaya mvura uye kubviswa kwemercaptan rinopinda mufiriji yeguruva regasi rechigadzirwa kuti ribvise guruva remamorekuru, uye robva ratumirwa 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.
