Sei Yakagadziriswa Alumina Yakakosha MuClaus Sulfur Recovery process?
Iyo alumina catalysts inoshandiswa muClaus Sulfur Recovery Units inomiririra yakasarudzika uye yakashandiswa zvakanyanya kirasi yezvigadziriso zvechishandiso ichi. Yakakwira-kuchena yakabatidzwa alumina inokonzeresa kuita kwehydrogen sulfide (H2S) uye sulfur dioxide (SO2) kugadzira elemental sulfur (S), ukuwo panguva imwe chete ichisimudzira hydrolysis yesarufa-ine-zvinogadzirwa zvakaita secarbonyl sulfide (COS) uye carbon disulfide (CS2), nekudaro kusimudzira mwero wekudzoreredza sarufa.
Chii chinonzi Claus Process Sulfur Recovery?
Iyo Claus process ndeimwe yeanonyanya kushandiswa sarufa kudzoreredza tekinoroji muindasitiri yemazuva ano. Inonyanya kushandiswa kushandura acidic gasi rine H2S kupinda elemental S, uku ichideredza kusvibiswa kwezvakatipoteredza kunokonzerwa nekubuda kwakananga kwema sulfides. Iyo Claus process kudzoreredza sulfur inoshanda kune akasiyana siyana maindasitiri anogadzira huwandu hukuru hwesarufa-inotakura magasi esidhi, akadai se:
* Mafuta ekunatsa: kudzoreredza sarufa kubva kune asidhi magasi anogadzirwa panguva yekunatsa maitiro;
* Yakasikwa gasi kugadzirisa: kurapa asidhi magasi anogadzirwa panguva yechisikigo gasi desulfurization;
* Indasitiri yemakemikari emarasha: kurapa sarufa-inotakura asidhi magasi anogadzirwa panguva yemarasha gasi uye kunatsa syngas;
* Indasitiri yekubika: kushandura hydrogen sulfide mucoke oven gasi kuita elemental sulfur;
* Petrochemical indasitiri: kudzoreredza sarufa kubva kuH2S{{0}iine magasi anogadzirwa;
* Maindasitiri ane hukama neSulfide{0}: kubata nesarufa-ine magasi emarara anobva kusulfuric acid, viscose, nemakemikari fibers.
Ndekupi Alumina Catalyst Yakaiswa MuClaus process?
Yakajairika Claus process sulfur recovery unit inosanganisira acid gasi feed system, acid gasi vira, tsvina inopisa boiler, sulfur condensers, Claus catalytic reactors, uye liquid sulfur yekuunganidza gomba kana sulfur seal tank.
Mhedzisiro yekuita kweClaus process ndeyekuita pakati peH2S uye SO2kugadzira elemental sulfur. Mukuita, chikamu cheH2S inotanga kupiswa kugadzira SO2; izvo zvinoguma SO2obva aita neasara H2S over a catalyst{{0}maitirwo eClaus-kuburitsa mhute yesarufa, inoburitsa mvura sarufa pakutonhodza.
Naizvozvo,Claus alumina catalystsanonyanya kushandiswa mune idzi catalytic reactors. Uye yakajairwa indasitiri yeClaus catalyst mibhedha inowanzo shandisa activated alumina.
Mabasa eAlumina Alumina Catalyst MuClaus process
Kukurudzira kuita kukuru kwaClaus. Iri ndiro basa rakakosha! Pasina catalyst, chiyero chekuita pakati peH2S uye SO2iri kunonoka; zvisinei, activated alumina inopa akawanda anoshanda epamusoro masaiti, zvichiita kuti maitiro acho akurumidze kusvika pakuenzanisa patembiricha inogamuchirika mumaindasitiri.
Catalyzing COS hydrolysis. Mukuwedzera kune H2S, gasi reasidhi rinenge rine CO2, mahydrocarbon, uye mashoma eorganic sulfides. Muchoto chekupisa, imwe sarufa{{1}ine macompounds anoumba COS neCS.2. Activated alumina inokonzeresa shanduko yesarufa mukati meCOS kudzoka muH2S, kuibvumira kupinda muClaus reaction system; izvi zvakakosha pakuwedzera huwandu hwese sulfur kudzoreredza mwero.
Catalyzing CS2hydrolysis. CS2ndeyekubuda kwekunetseka kwakanyanya mukuita kwaClaus. Hydrolysis ye CS2inoshandura sarufa iri mukati memorekuru kudzokera kuH2S, kuigonesa kuti igozotora chikamu mukuita kweClaus; iri nderimwe basa rakakosha reyakagadziriswa alumina catalysts.
Sei Yakagadziriswa Alumina Ichidikanwa MuClaus Sulfur Recovery?
Kune alumina{{0}based Claus catalysts, kiyi haisi kungo wedzera Al2O3content. Pane kudaro, inoda kukwenenzverwa kweiyo chaiyo nzvimbo, chimiro chepore, chiitiko chepamusoro, uye kuramba kudzima.
Tichifunga nezvekusiyana kwema molecular saizi yeH2S, SO2, COS, CS2,uye H2O-uye nyaya yekuti kuita kwaClaus kunosanganisira kupararira kwe-zvikamu zvegasi mukati mezvimedu zvinokonzeresa-kutarisira kukura kwepore kwakakosha. Kana ma pores ari madiki, reactant diffusion inodzivirirwa uye mukati mekupararira kuramba kunowedzera, kudzivirira kushandiswa kuzere kwenzvimbo dzinoshanda mukati meiyo catalyst. Sezvineiwo, kana pores yakakura kwazvo, nhamba yenzvimbo dzinoshanda inoderera. Nekuda kweizvozvo, maindasitiri Claus catalysts anoda yakanyatso kugadzirwa pore saizi yekugovera, uye yakashongedzwa alumina inogona kupa inodiwa pamusoro pezvivakwa uye pore zvimiro kuzadzisa izvi zvinodiwa.
