Chii chinonzi Sulfur Recovery?
Sulfur kuporainzira yakakosha muindasitiri yekunatsa petroleum, ine chinangwa chekubvisa sulfur makomisheni kubva mumafuta asina kuchena uye zvinobva pairi. Iyi nzira yakakosha pakusangana nemirairo yezvakatipoteredza uye kugadzira mafuta akachena. Mishonga yeSulfur, kana isina kubviswa, inogona kutungamirira pakuumbwa kwesarufa dioxide (SO₂) panguva yekupisa, zvichiita kuti kusvibiswa kwemhepo uye mvura inonaya asidi. Iyo sarufa yekudzoreredza maitiro inowanzo sanganisira kushandura hydrogen sulfide (H₂S), byproduct yekunatsa, kuita elemental sulfur kana sulfuric acid.
Imwe yedzakanyanya kushandiswa nzira dzekupora sarufandiyo nzira yeClaus, iyo inosanganisira nhevedzano yemakemikari maitiro anoshandura H₂S kuita elemental sulfur. Maitiro acho anowanzo sanganisira zvinopisa uye zvinokonzeresa nhanho, apo H₂S inotanga muchidimbu oxidized kuita sulfur dioxide (SO₂) uye yozoita neH₂S yakawanda kugadzira sarufa nemvura. Kubudirira kweClaus process kunogona kukwidziridzwa nekuibatanidza nemamwe matekinoroji, senge miswe gasi kurapwa zvikamu, kuti uwane yakakwirira sarufa kudzoreredza mazinga.
PR-100 uye Basa Rayo muKudzoreredza Sulfur
PR-100 ndeye proprietary catalyst inoshandiswa mune sulfur recovery process. Yakagadzirirwa kusimudzira kushanda kweClaus process nekuvandudza mazinga ekushandurwa kweH₂S kune elemental sulfur. ThePR-100 catalystinozivikanwa nokuda kwebasa rayo repamusoro uye kugadzikana, izvo zvinobvumira kuita zviri nani muzvikamu zvekugadzirisa sulfur. Nekushandisa PR-100, marefineries anogona kuwana yakakwira sulfuri kudzoreredza mazinga, kuderedza kuburitswa, uye kutevedzera inoomesera mitemo yezvakatipoteredza.
Iyo PR-100 catalyst inoshanda nekupa yakakwana nzvimbo yemakemikari maitiro anobatanidzwa muClaus process. Inofambisa oxidation yeH₂S kuenda kuSO₂ uye kunotevera kuita kweSO₂ neH₂S kugadzira sarufa. Iyo catalyst nzvimbo yepamusoro uye nzvimbo dzinoshanda dzinovimbisa kuti izvi zvinokonzeresa zvinoitika nemazvo, kunyangwe pakudzika kwakadzika. Izvi hazvingonatsiridza huwandu hwese sulfur yekudzoreredza asi zvakare inoderedza kushandiswa kwesimba kwemaitiro.
CCR Reforming yeGasoline Production
Kuenderera mberi Catalytic Reforming (CCR) inzira yakakosha mukugadzirwa kwepeturu yepamusoro-octane. Inosanganisira kushandurwa kwe low-octane naphtha kuita yakakwira-octane reformate, inova chikamu chakakosha chepeturu. Maitiro eCCR anoshandisa platinamu-based catalyst kufambisa dehydrogenation, isomerization, uye cyclization yemahydrocarbons, zvichikonzera kuumbwa kweanonhuhwirira makomisheni anowedzera chiyero cheoctane yepeturu.
Nzira yeCCR inoenderera mberi, zvinoreva kuti iyo catalyst inovandudzwa zvakare mu situ, ichibvumira kushanda kusina kukanganiswa. Izvi zvinowanikwa nekuramba uchibvisa iyo yakashandiswa catalyst, ichiigadzira patsva nekupisa kubva kune coke deposits, uye wozoidzosera mureactor. Kuenderera mberi kwemaitiro eCCR kunovimbisa kuwanikwa kwakasimba kwepamusoro-octane reformate, iyo yakakosha pakuzadzisa kudiwa kwepeturu yemhando yepamusoro.
Kubatanidzwa kweSulfur Recovery uyeKuchinja kweCCR
Iko kubatanidzwa kwesarufa kudzoreredza uye CCR kugadzirisa maitiro kwakakosha kune yemazuva ano yekunatsa. Iyo sarufa yekudzoreredza maitiro inova nechokwadi chekuti H₂S inogadzirwa panguva yekunatswa inoshandurwa zvine mutsindo kuita elemental sarufa, kuderedza kuburitsa uye kukanganisa kwezvakatipoteredza. Kune rimwe divi, iyo CCR yekuvandudza maitiro inowedzera kunaka kwepeturu nekuwedzera iyo octane chiyero.
Nekubatanidza maitiro aya, marefineries anogona kuwana zvese kutevedzera kwezvakatipoteredza uye mhando yechigadzirwa. Kushandiswa kwepamusoro catalysts sePR-100mu sulfur recovery uye platinum-based catalysts muCCR reforming inovimbisa kuti maitiro aya anoshanda uye anoshanda. Kubatanidzwa uku hakungobatsiri chete zvinochenesa kuita zvinodiwa nemutemo asi zvakare zvinoita kuti vakwanise kugadzira mafuta emhando yepamusoro anoenderana nezvido zvemusika.
Mukupedzisa, kudzoreredza sarufa inzira yakakosha muindasitiri yekunatsa peturu, ine chinangwa chekubvisa sulfur makomisheni uye kuderedza kuburitswa. Kushandiswa kwepamusoro catalysts sePR-100inowedzera kushanda kweiyo sulfur recovery process. Uyezve,CCR kuchinjainoita basa rakakosha mukugadzira peturu yepamusoro-octane. Kubatanidzwa kwemaitiro aya kunovimbisa kuti zvinonatsa zvinogona kuzadzisa zvese zviri zviviri kutevedza kwezvakatipoteredza uye mhando yechigadzirwa, zvichibatsira kune yakachena uye inoshanda zvakanyanya simba nzvimbo.
