Chikamu chekuchenesa gasi rehydrogen sulfide

Nhanganyaya

Nekukura kwenharaunda yedu, tinotsigira simba rakachena, saka kudiwa kwegasi rechisikigo sesimba rakachena kuri kuwedzerawo. Zvisinei, mukushandiswa kwegasi rechisikigo, matsime mazhinji egasi anowanzova nehydrogen sulfide, iyo inokonzera ngura yemidziyo nemapaipi, inosvibisa nharaunda uye inoisa hutano hwevanhu panjodzi. Nekukura kwesainzi netekinoroji, Kushandiswa kwakakura kwetekinoroji yekubvisa sulfurization yegasi rechisikigo kwakagadzirisa matambudziko aya, asi panguva imwe chete, mutengo wekuchenesa nekurapa gasi rechisikigo wakawedzera zvinoenderana.

Nheyo

Kubvisa sulphurization yemuseve weMolecular (inonziwo desulfurization) skid, inonziwo molecular sieve sweeting skid, chishandiso chakakosha mukuchenesa gasi rechisikigo kana chirongwa chekudzora gasi rechisikigo.

Molecular sieve ikristalo yealkali metal aluminosilicate ine chimiro chemapfupa uye chimiro chakafanana che microporous. I absorbent ine mashandiro akanaka kwazvo, kugona kwakanyanya kunyudza uye kusarudza adsorption. Chekutanga, kune nzira dzakawanda dzine saizi yakafanana ye pore uye maburi akarongwa zvakanaka muchimiro che molecular sieve, izvo zvisingangopi nzvimbo yakakura chete, asiwo zvinoganhurira kupinda kwemamorekuru akakura kupfuura maburi; Chechipiri, pamusoro pe molecular sieve ine polarity yakakura nekuda kwehunhu hwe ionic lattice, saka ine kugona kwakanyanya kunyudza kwemamorekuru asina kuguta, mamorekuru e polar uye mamorekuru anogona kunyudza. Mvura ne hydrogen sulfide mamorekuru e polar, uye dhayamita ye molecular idiki pane dhayamita ye pore ye molecular sieve. Kana gasi risina kubikwa rine trace water richipfuura nepamubhedha we molecular sieve patembiricha yemumba, trace water ne hydrogen sulfide zvinonyudzwa, Saka, huwandu hwemvura ne hydrogen sulfide mu feed gas hunodzikira, uye chinangwa chekushaya mvura uye desulfurization chinoitika. Maitiro ekunyudza musefa yemamorekuru anosanganisira kunyudza mumasero uye kunyudza kwemuviri kunokonzerwa nesimba revan der Waals. Sekureva kweKelvin equation, kunyudza mumasero kunoderera nekuwedzera kwekupisa, nepo kunyudza mumuviri kuri maitiro e exothermic, uye kunyudza kwayo kunoderera nekuwedzera kwekupisa uye kunowedzera nekuwedzera kwekumanikidzwa; Nokudaro, maitiro ekunyudza musefa yemamorekuru anowanzoitwa pakupisa kwakaderera uye kumanikidzwa kwakanyanya, nepo kunyudza kwekuongorora kuchiitwa pakupisa kwakakwirira uye kumanikidzwa kwakaderera. Pasi pechiito chegasi rekuvandudza tembiricha yakakwira, yakachena uye yakaderera, molecular sieve adsorbent inoburitsa adsorbate mu micropore mugasi rekuvandudza kusvika huwandu hwe adsorbate mu adsorbent hwasvika padanho rakaderera. Inewo kugona kunyudza mvura nehydrogen sulfide kubva mugasi rekudya, zvichiita kuti maitiro ekuvandudza nekudzokorodza esefa abudirire.

Maitiro etekinoroji

Kufamba kwemaitiro kunoratidzwa mudhayagiramu. Chigadziko ichi chinoshandisa nzira nhatu dzemashongwe, imwe shongwe yekunyungudutsa, imwe shongwe yekudzoreredza uye imwe shongwe yekutonhodza. Kana gasi rekunyungudutsa richipinda muchikamu, tembiricha yegasi rekunyungudutsa inoderedzwa nechikamu chekutonhodza, mvura inobviswa nechikamu chekuparadzanisa checoalescence, uye yobva yapinda muchikamu chekunyungudutsa chemolecular sieve a-801, a-802 uye a-803. Mvura nehydrogen sulfide mugasi rekunyungudutsa zvinonyungudutswa nechikamu chekunyungudutsa kuti zviite kuti mvura ibude uye hydrogen sulfide adsorption process. Gasi rakacheneswa rekubvisa mvura kubva mumhepo uye hydrogen sulfide removal rinopinda muchikamu chekunyungudutsa guruva regasi remocular kuti ribvise guruva remamolecular sieve uye rinotumirwa kunze kwenyika segasi rezvigadzirwa.

Sefa yemamorekuru inoda kugadziriswa mushure mekunyudza huwandu hwakati hwemvura nehydrogen sulfide. Chikamu chegasi rechigadzirwa chinoburitswa kubva mugasi rechigadzirwa mushure mekusefa guruva segasi rekugadzirisa. Mushure mekunge gasi rapiswa kusvika 270 ℃ muchoto chekupisa, shongwe inodziiswa zvishoma nezvishoma kusvika 270 ℃ kubva kumusoro kusvika pasi kuburikidza neshongwe yekubvisa sulfurization yemolekyulu iyo yapedza maitiro ekunyudza, kuitira kuti mvura nehydrogen sulfide zvakanyudzwa pasefa yemamorekuru zvigone kugadziriswa kuti zvive gasi rekugadzirisa rakawanda uye kupedzisa maitiro ekugadzirisa.

Gasi rekugadzirisa zvinhu rakapfuma mushure mekubuda mushongwe yekuvandudza zvinhu rinopinda mukondensa yekuvandudza zvinhu kuti ritonhore kusvika pa50 ℃, uye gasi racho rinotonhodzwa roendeswa kuflare header.

Nhare yekusefa yemolecular inofanira kutonhodzwa mushure mekudzoreredzwa. Kuti idzorerwe zvizere uye ishandise simba rekupisa, gasi rekugadzirisa rinotanga kushandiswa segasi rinotonhorera rinofefetera, uye nhare inotonhodzwa kusvika pa50 ℃ kubva kumusoro kusvika pasi kuburikidza nenhare yekusefa yemolecular sieve yakapedza maitiro ekugadzirisa. Panguva imwe chete, inopiswa yoga. Mushure mekunge gasi rinotonhorera rinofefetera rabuda munhare yekutonhodza, rinopinda muchoto chekupisa chegasi rekugadzirisa kuti ridziye, uye robva ragadzirisa nhare yekusefa yemolecular sieve desulfurization segasi rekugadzirisa risina simba. Mudziyo unochinja maawa masere ega ega.
