Kubera iki Alumina ikoreshwa ihambaye mu nzira yo gusubiza ikibiriti ca Claus?
Ivyo bikoresho vy’ivyuma bikoreshwa mu bikoresho vy’ugusubizaho ikibiriti vya Claus bigereranya umugwi w’ibikoresho vya kera kandi bikoreshwa cane muri iki gikorwa. Alumina ikoreshwa n'ubusuku bwinshi-ituma habaho ugukorana hagati y'ivyuma vy'iyidrojeni (H2S) n’ikibiriti (SO2) kugira ngo haboneke ikibiriti c’ibintu (S), mu gihe icarimwe gitera imbere uguhinduka kw’amazi kw’ikibiriti-kirimwo ibintu biva mu - nk’ikibiriti c’umubiri (COS) n’ikibiriti c’umubiri (CS2), gutyo bikaba bituma igipimo co gusubirana c’ikibiriti kirushirizaho.
Igikorwa kijanye n’ugusubirana kw’ikibiriti ni iki?
Uburyo bwa Claus ni bumwe mu buhinga bukoreshwa cane bwo gusubiza ikibiriti mu nganda zo muri iki gihe. Ikoreshwa cane cane mu guhindura gaze y’aside irimwo H .2S mu bihimba S, mu gihe bigabanya ubuhumane bw’ibidukikije buterwa n’ugusohoka kw’ibintu bita sulfides. Uburyo bwa Claus bwo gusubiza ikibiriti bukoreshwa mu bikorwa bitandukanye vy’inganda bitanga ikibiriti kinini-gifise imyuka y’aside, nka:
* Amahinguriro yo gutunganya amavuta: gukura ikibiriti mu myuka y’aside iva mu gihe c’ibikorwa vyo gutunganya;
* Gutunganya gazi kavukire: gusukura gazi kavukire iva mu gihe c’ugukuraho ikibiriti muri gazi kavukire;
* Inganda y’imiti y’amakara: gusukura imyuka y’aside irimwo ikibiriti-ivuye mu gihe c’uguhindura amakara gazi n’ugusukura imyuka y’aside;
* Inganda zikora coke: guhindura hydrogène sulfure iri mu gazi y’ifuru ya coke ngo ibe ikibiriti c’ibintu;
* Inganda zikora amavuta ya peteroli: kugira ngo zironke ikibiriti kiva muri H2S-irimwo imyuka y'ibikorwa;
* Inganda zijanye n’ivyuma vy’ikibiriti-: gukorana n’ikibiriti-kirimwo imyuka y’umwanda iva kuri aside sulfurique, viscose, n’ivyuma vy’imiti.
Ni hehe Alumina Catalyst Ishirwa Mu Nzira ya Claus?
Igikoresho gisanzwe co gusubiza ikibiriti mu buryo bwa Claus gifise uburyo bwo gutanga gazi y’aside, ifuru y’agazi y’aside, igikoresho co gukoresha ubushuhe buva mu myanda, ibikoresho bitera ikibiriti, ibikoresho bitera ikibiriti, n’ikinogo co gukusanya ikibiriti c’amazi canke itangi ry’ikibiriti.
Inyishu nyamukuru y’urugendo rwa Claus ni inyishu hagati ya H .2S na SO2kugira ngo haboneke ikibiriti c’ibintu. Mu bikorwa, igice c’ivyo H .2S ni yo ibanza guturirwa kugira ngo ivyare SO .2; igisubizo SO2hanyuma agakorana n’ivyo H bisigaye .2S hejuru y’ikintu gitera umuriro-inyishu ya Claus-kugira ngo haboneke umwotsi w’ikibiriti, utanga ikibiriti c’amazi iyo gikonjeshejwe.
Rero,Ivyuma vy'alumina vya Clausni vyo bikoreshwa canecane muri ivyo bikoresho bitera umuriro. Kandi ibitanda vy’ivyuma vy’inganda vy’i Claus bikoresha alumina ikoreshwa.
Imikorere ya Alumina Catalyst ikoreshwa mu nzira ya Claus
Gutuma Claus agira inyishu nyamukuru. Ico ni co gikorwa gihambaye kuruta ibindi vyose! Ata kintu gitera, igipimo c’ugusubirana hagati ya H .2S na SO2ni ukugenda buhoro cane; ariko rero, alumina ikoreshwa itanga ibibanza vyinshi bikora, bikaba bituma iyo nzira ishobora kwegera uburinganire ningoga ku bushuhe bwemewe n’inganda.
Gutuma COS ihinduka amazi. Ivyongeyeko kuri H .2S, gazi y'aside mu bisanzwe irimwo CO2, ivyuma bita hydrocarbures be n’ibintu bikeyi bita sulfures organiques. Mu ntambara y’ubushuhe, hariho ikibiriti-kirimwo ibintu bifise ubuzima bikora COS na CS .2. Alumina ikoreshwa ituma ikibiriti kiri muri COS gisubira kuba H .2S, bikayireka ngo yinjire mu nzira y’ugusubiza kwa Claus; ivyo ni ngirakamaro kugira ngo umuntu ashobore kuronka igipimo cose c’ugusubirana kw’ikibiriti.
Gutera imbere CS2n’amazi. CS2ni ikintu gitera ubwoba cane mu nzira ya Claus. Ihinduka ry'amazi rya CS2ihindura ikibiriti kiri muri iyo molecule kigasubira kuba H .2S, bikayishoboza mu nyuma kugira uruhara mu nyishu ya Claus; iki ni ikindi gikorwa nyamukuru c’ibikoresho vy’ivyuma vy’alumina bikora.
Ni kuki Alumina Ikoreshwa Ikenewe Mu Gusubizaho Ikibiriti ca Claus?
Ku bikoresho vy’ubuhinga bwa Claus bishingiye kuri alumina-, urufunguruzo si ugutuma Al .2O3ibirimwo. Ahubwo, bisaba gutuma habaho ugutunganya neza ahantu h’imbere, imiterere y’ibihengeri, igikorwa co ku ruhande, n’ukuntu bishobora guhangana n’uguhagarara.
Hakurikijwe ubunini butandukanye bw’ibihimba vya H .2S, SO2, COS, CS2, na H2O-kandi kuba inyishu ya Claus ijana n’ugukwiragira kw’imiyaga myinshi-mu bice vy’ibinyabuzima-ugucungera ubunini bw’ibihengeri ni ikintu gihambaye cane. Iyo amaporo ari mato cane, ugukwiragira kw’ibintu bikora birabangamirwa kandi ubushobozi bwo gukwiragira imbere buragwira, bikaba bibuza gukoresha neza ibibanza bikora biri mu gikoresho gitera umuriro. Ku rundi ruhande, iyo amaporo ari manini cane, igitigiri c’ibibanza bikora kiragabanuka. Ku bw’ivyo, ibikoresho vy’inganda vyitwa Claus bisaba ko habaho ugusangira ubunini bw’ibihengeri, kandi alumina ikoreshwa irashobora gutanga imiterere y’imbere n’imiterere y’ibihengeri bikenewe kugira ngo ivyo bisabwa bishobore gushikwako.
Sinmat imitiitanga ubusuku burengeye -igikoresho gikora aluminacane cane ku bijanye n’ugusubirana kw’ikibiriti. Ushaka kumenya vyinshi, raba kurialumina yakoreshejweurutonde rw'ibicuruzwa.
