Kodi Sulfur Recovery ndi chiyani?
Kuchira kwa sulufulendi njira yovuta kwambiri pantchito yoyenga mafuta, yomwe cholinga chake ndi kuchotsa mankhwala a sulfure m'mafuta akuda ndi zotuluka zake. Izi ndizofunikira pokwaniritsa malamulo a chilengedwe komanso kupanga mafuta oyeretsera. Mankhwala a sulfure, ngati sanachotsedwe, angapangitse kupanga sulfure dioxide (SO₂) panthawi yoyaka, zomwe zimapangitsa kuti mpweya uwonongeke komanso mvula ya asidi. Njira yobwezeretsanso sulufule nthawi zambiri imaphatikizapo kusintha hydrogen sulfide (H₂S), njira yoyeretsera, kukhala sulfure yoyambira kapena sulfuric acid.
Imodzi mwa njira zomwe zimagwiritsidwa ntchito kwambirikuchira sulfurendi njira ya Claus, yomwe imaphatikizapo zinthu zingapo zomwe zimasintha H₂S kukhala sulfure wamba. Njirayi nthawi zambiri imaphatikizapo magawo otentha komanso othandizira, pomwe H₂S imayamba kukhala ndi okosijeni pang'ono ku sulfure dioxide (SO₂) ndiyeno imakhudzidwa ndi H₂S yochulukirapo kuti ipange sulfure ndi madzi. Kuchita bwino kwa njira ya Claus kumatha kukulitsidwa mwa kuphatikizira ndi matekinoloje ena, monga mayunitsi opangira mpweya wa mchira, kuti akwaniritse kuchuluka kwa sulfure.
PR-100 ndi Udindo Wake mu Kubwezeretsa Sulfur
PR-100 ndi chothandizira chomwe chimagwiritsidwa ntchito pobwezeretsa sulfure. Idapangidwa kuti ipititse patsogolo magwiridwe antchito a Claus pokweza kusintha kwa H₂S kupita ku elemental sulfure. ThePR-100 chothandiziraamadziwika chifukwa cha ntchito zake zapamwamba komanso kukhazikika, zomwe zimapangitsa kuti pakhale ntchito yabwino mumagulu obwezeretsa sulfure. Pogwiritsa ntchito PR-100, zoyenga zimatha kukwaniritsa kuchuluka kwa sulfure, kuchepetsa mpweya, ndikutsatira malamulo okhwima a chilengedwe.
Chothandizira cha PR-100 chimagwira ntchito popereka malo abwino kwambiri okhudzana ndi machitidwe a mankhwala omwe akukhudzidwa ndi ndondomeko ya Claus. Imathandizira kutsekemera kwa H₂S kupita ku SO₂ komanso kachitidwe kotsatira ka SO₂ ndi H₂S kupanga sulfure. Malo okwera kwambiri a chothandizira komanso malo omwe akugwira ntchito amaonetsetsa kuti zochitikazi zimachitika bwino, ngakhale kutentha kochepa. Izi sizimangowonjezera kuchuluka kwa sulfure kuchira komanso kumachepetsa kugwiritsa ntchito mphamvu pakuchitapo kanthu.
CCR Reforming for Gasoline Production
Continuous Catalytic Reforming (CCR) ndi njira yofunika kwambiri popanga mafuta a octane apamwamba. Zimaphatikizapo kutembenuka kwa octane otsika kukhala octane reformate, yomwe ndi gawo lalikulu la mafuta. Njira ya CCR imagwiritsa ntchito chothandizira chochokera ku platinamu kuti chithandizire kutulutsa madzi, isomerization, ndi cyclization ya ma hydrocarbons, zomwe zimapangitsa kuti pakhale mankhwala onunkhira omwe amawonjezera kuchuluka kwa octane wamafuta.
Njira ya CCR ikupitirirabe, kutanthauza kuti chothandizira chimasinthidwanso mu situ, kulola kuti ntchitoyo isasokonezeke. Izi zimatheka pochotsa mosalekeza chothandizira chomwe chagwiritsidwa ntchito, ndikuchikonzanso powotcha ma depositi a coke, ndikuchibwezeretsanso mu riyakitala. Kupitilira kwa njira ya CCR kumapangitsa kuti pakhale kupezeka kwapamwamba kwa octane reformate, komwe ndikofunikira pakukwaniritsa kufunikira kwamafuta apamwamba kwambiri.
Kuphatikiza kwa Sulfur Recovery ndiKusintha kwa CCR
Kuphatikizika kwa sulfure kuchira ndi kukonzanso kwa CCR ndikofunikira kwa zoyenga zamakono. Njira yobwezeretsanso sulfure imatsimikizira kuti H₂S yomwe imapangidwa panthawi yoyenga imasinthidwa bwino kukhala sulfure ya elemental sulfure, kuchepetsa kutulutsa mpweya komanso kuwononga chilengedwe. Kumbali inayi, njira yosinthira CCR imakulitsa mtundu wamafuta powonjezera kuchuluka kwa octane.
Mwa kuphatikiza njirazi, zoyenga zimatha kukwaniritsa zonse kutsata chilengedwe komanso mtundu wazinthu. Kugwiritsa ntchito zida zapamwamba mongaPR-100mu kubwezeretsa sulfure ndi zopangira platinamu mu CCR reforming zimatsimikizira kuti njirazi ndi zogwira mtima komanso zogwira mtima. Kuphatikizika kumeneku sikumangothandiza oyeretsa kuti akwaniritse zofunikira zowongolera komanso kumawathandiza kupanga mafuta apamwamba kwambiri omwe amakwaniritsa zomwe msika ukufunikira.
Pomaliza, kuchira kwa sulfure ndi njira yofunikira kwambiri pantchito yoyenga mafuta, yomwe cholinga chake ndi kuchotsa zinthu za sulfure ndikuchepetsa utsi. Kugwiritsa ntchito zida zapamwamba mongaPR-100kumawonjezera mphamvu ya sulfure kuchira ndondomeko. Kuonjezera apo,Kusintha kwa mtengo wa CCRimagwira ntchito yofunika kwambiri popanga mafuta ochulukirapo a octane. Kuphatikizika kwa njirazi kumatsimikizira kuti zoyenga zimatha kukwaniritsa zonse kutsata chilengedwe komanso mtundu wazinthu, zomwe zimathandizira kuti pakhale malo oyeretsa komanso opatsa mphamvu.
