Kuki Gukora Alumina Byingenzi Muburyo bwo Kugarura Amazi ya Sufuru?
Alumina catalizator ikoreshwa muri Claus Sulfur Recovery Units ihagarariye icyiciro cya kera kandi gikoreshwa cyane mubyiciro bya catalizike kuriyi porogaramu. Hejuru - isuku ikora alumina itera reaction hagati ya hydrogen sulfide (H.2S) na dioxyde de sulfure (SO2) kubyara sulfure yibanze (S), mugihe icyarimwe iteza imbere hydrolysis ya sulfuru - irimo ibicuruzwa - nka karubone sulfide (COS) na karubone disulfide (CS)2), bityo bikazamura igipimo cyo kugarura sulfure.
Ni ubuhe buryo bwa Claus Gutunganya Amazi?
Inzira ya Claus ni bumwe mu buryo bukoreshwa cyane mu kugarura sulfuru mu nganda zigezweho. Ikoreshwa cyane muguhindura gaze acide irimo H.2S mubice S, mugihe hagabanijwe kwanduza ibidukikije biterwa no gusohora sulfide itaziguye. Inzira ya Claus itunganya sulfure ikoreshwa mubikorwa bitandukanye byinganda zitanga sulfure nyinshi - zifite imyuka ya aside, nka:
* Gutunganya amavuta: kugarura sulfure mu myuka ya aside ikorwa mugihe cyo gutunganya;
* Gutunganya gaze karemano: kuvura imyuka ya aside ikorwa mugihe cya gazi isanzwe;
* Inganda zikora amakara: kuvura sulfuru - zifite imyuka ya aside ikorwa mugihe cyo gusohora amakara no kweza syngas;
* Inganda zo guteka: guhindura hydrogène sulfide muri gaze ya feri ya kokiya mo sulfure yibanze;
* Inganda zikomoka kuri peteroli: kugarura sulfure kuri H.2S - irimo imyuka itunganya;
* Sulfide inganda - inganda zijyanye: guhangana na sulfuru - irimo imyuka iva muri acide sulfurike, viscose, na fibre fibre.
Nihe Cataliste ya Alumina Ihagaze Mubikorwa bya Claus?
Igice gisanzwe cya Claus gikora sulfure igizwe na sisitemu yo kugaburira gaze ya acide, itanura rya gaze ya acide, icyuma gishyushya imyanda, kondereseri ya sulferi, reaction ya Claus catalitike, hamwe n’ikigega cyo gukusanya amazi ya sulferi cyangwa ikigega cya kashe ya sulferi.
Igisubizo cyibanze cyibikorwa bya Claus nigisubizo hagati ya H.2S na SO2kubyara sulfure yibanze. Mu myitozo, igice cya H.2S yabanje gutwikwa kubyara SO2; ibisubizo SO2hanyuma ikora hamwe na H. isigaye2S hejuru ya catalizator - reaction ya Claus - kugirango itange imyuka ya sulfure, itanga sulfure y'amazi imaze gukonja.
Kubwibyo,Claus aluminazikoreshwa cyane cyane muri reaction ya catalitiki. Kandi ibitanda bisanzwe bya Claus catalizator ibitanda mubisanzwe bikoresha alumina ikora.
Imikorere Yumukoresha wa Alumina Cataliste Mubikorwa bya Claus
Gutezimbere ibyingenzi byingenzi. Nibikorwa byingenzi! Hatari umusemburo, igipimo cyibisubizo hagati ya H.2S na SO2ni buhoro; icyakora, alumina ikora itanga ibibanza byinshi byubuso bukora, bigafasha reaction yo kwihuta kuringaniza mubushuhe bwemewe ninganda.
Gutangiza COS hydrolysis. Kuri H.2S, gaze ya aside mubisanzwe irimo CO2, hydrocarbone, hamwe na sulfide nkeya. Mu itanura rya reaction yumuriro, sulfure - irimo ibinyabuzima bigize COS na CS2. Alumina ikora itera guhindura sulfure muri COS igasubira muri H.2S, kubemerera kwinjira muri sisitemu ya reaction ya Claus; ibi nibyingenzi mugukwirakwiza igipimo cya sulfuru yose.
Catalize CS2hydrolysis. CS2ni byproduct yibibazo byihariye mubikorwa bya Claus. Hydrolysis ya CS2ihindura sulfure iri muri molekile isubira muri H.2S, igushoboza kwitabira nyuma ya reaction ya Claus; iyi nibindi bikorwa byingenzi bya alumina ikora.
Ni ukubera iki Gukora Alumina Bikenewe Muri Claus Sulfure?
Kuri alumina - ishingiye kuri catalizike ya Claus, urufunguzo ntabwo ari ukurenza Al gusa2O3ibirimo. Ahubwo, bisaba kunonosora byimazeyo ubuso bwihariye, imiterere ya pore, ibikorwa byubuso, hamwe no kurwanya gukuraho.
Urebye ubunini butandukanye bwa H.2S, SO2, COS, CS2, na H.2O - no kuba reaction ya Claus ikubiyemo gukwirakwiza imyuka myinshi - ibice bigize catalizator - gucunga ingano ya pore ni ngombwa. Niba imyenge ari nto cyane, ikwirakwizwa ryimyitozo irabangamiwe kandi irwanya ikwirakwizwa ryimbere ryiyongera, irinda ikoreshwa ryuzuye ryibikorwa bikora muri catalizator. Ibinyuranye, niba imyenge ari nini cyane, umubare wibikorwa bikora uragabanuka. Kubera iyo mpamvu, inganda za Claus catalizator zisaba gukwirakwiza ingano ya pore yakozwe, kandi alumina ikora irashobora gutanga imitungo ikenewe hamwe nububiko bwa pore kugirango byuzuze ibyo bisabwa.
Sinmatikiitanga umwihariko wo hejuru - ubuziranengeikora ya aluminabyumwihariko kubikorwa bya Claus gutunganya sulfure. Kubindi bisobanuro, nyamuneka reba kurigukora aluminaicyiciro cyibicuruzwa.
