Shaanxi United Chemical: Ukuhlinzeka Ngezixazululo Zesodium Cyanide Eluhlaza EKazakhstan

Emkhakheni wokuhlinzekwa kwemikhiqizo yamakhemikhali, uShaanxi United Chemical ubelokhu ehamba phambili embonini ngesithombe sobuchwepheshe nesinomthwalo wemfanelo. Manje, sihlonipheke kakhulu ukukwazi ukuhlinzeka ngekhwalithi ephezulu I-Sodium Cyanide imikhiqizo yaseKazakhstan.

Sodium i-cyanide, njengento ebalulekile yamakhemikhali eluhlaza, isetshenziswa kakhulu emikhakheni eminingi yezimboni, ikakhulukazi embonini yezimayini zegolide kanye nenzuzo. Kodwa-ke, ngenxa yezakhiwo zayo ezikhethekile, ilawulwa ngokuqinile nguhulumeni waseChina. Siphinde sazi ngokujulile ngomonakalo ongase ube khona we i-sodium cyanide endaweni ezungezile. Uma i-cyanide - equkethe amanzi angcolile akhiqizwa ezimayini zegolide kanye nenqubo yokuhlomula ingaphathwa kahle, izoba yingozi enkulu emvelweni. I-cyanide emanzini angcolile ezitshalo zegolide ze-cyanidation inqunywa ukwakheka kwe-ore kanye nezimo zokusebenza. Ngaphezu kwe-cyanide, iqukethe nezinto zamakhemikhali ezifana ne-thiocyanate. Iningi lalawa ma-thiocyanate avela enqubweni yokungenisa umoya ekukhiqizeni noma ukusabela phakathi kwama-athomu e-cyanide nama-athomu esulfure angazinzile ngesikhathi sokukhishwa. Ngaphezu kwalokho, i-cyanide - equkethe amanzi angcolile iqukethe inani elikhulu le-cyanide yensimbi enobuthi kakhulu futhi ama-cyanides. Ngakho-ke, Shaanxi United Chemical akayena kuphela umphakeli womkhiqizo kodwa futhi ungumsebenzi we Ukuvikelwa kwemvelo.

Izinzuzo Zokuvikela Imvelo

Mayelana nokuvikelwa kwemvelo, sinezinzuzo ezibalulekile. Inkampani itshala isamba esikhulu sezinsiza ocwaningweni nasekuthuthukisweni kwezobuchwepheshe, futhi ihlinzeka ngosekelo oluphelele lwezobuchwepheshe ezinkingeni ezingaba khona zezemvelo ezingase ziphakame ngesikhathi sokukhiqiza, ukuthuthwa, ukugcinwa kanye nokusetshenziswa I-sodium cyanide. Ithimba lethu lochwepheshe lingasiza amabhizinisi endawo e-Kazakhstan ukuthi asungule uhlelo oluphelele lokuphatha imvelo futhi anciphise isizukulwane esingcolisayo esivela emthonjeni. Isibonelo, enqubweni yokukhiqiza, sisebenzisa ubuchwepheshe obuthuthukisiwe bokuhlanganisa okuluhlaza ukuze sithuthukise ukusetshenziswa kwempahla eluhlaza kanye nokunciphisa ukukhishwa kwemfucuza.

Izindlela Zokwelapha I-Cyanide - equkethe Amanzi Angcolile

Ekwelapheni i-cyanide - equkethe amanzi angcolile embonini yezimayini zegolide kanye nenzuzo, siyakwazi ukuhlukahluka kwezindlela ezivuthiwe nezisebenzayo:

• Indlela ye-Alkaline Chlorination: Lena indlela evamile yokucekela phansi Ama-cyanides emanzini angcolile ezitshalo zegolide ze-cyanidation futhi asetshenziswa kakhulu ekwelashweni kwamanzi angcolile ezitshalo ze-cyanide electroplating, izitshalo zegolide zegolide ze-cyanidation, izitshalo zegolide ze-cyanidation namanye amayunithi. Umgomo wawo ukusebenzisa i-chlorine ewuketshezi, igesi ye-chlorine noma impushana emhlophe ukuze kufakwe i-cyanide emanzini angcolile ibe yizinto ezingenabo ubuthi njenge-carbon dioxide ne-nitrogen.

• Sulfur Dioxide - Air Oxidation Indlela: Eyaziwa nangokuthi indlela ye-InCo, yasungulwa yi-American InCo Metals Company ekuqaleni kwawo-1980. Le ndlela isebenzisa i-sulphur dioxide nomoya njengama-oxidants ukuze kufakwe i-cyanides emanzini angcolile ngaphansi kwesimo se-copper - ion catalyst, ekhiqiza i-bicarbonate ne-ammonium ferrous sulfate. Ayikwazi ukususa kuphela i-cyanide ions yamahhala, i-hydrogen yamangqamuzana kanye ne-cyanides eyinkimbinkimbi, kodwa futhi isuse i-ferrocyanide complexes okunzima ukuyisusa ngendlela ye-chlorination, okwenza amanzi angcolile aphathwe ahlangabezane nezindinganiso zokukhishwa.

• I-Hydrogen Peroxide Oxidation Indlela: Ilungele ukwelapha i-low-concentration cyanide - equkethe amanzi angcolile. Ngaphansi kokusebenza kwe-copper - ion catalyst enenani le-pH ye-alkali engu-10 - 11. I-hydrogen peroxide ixoxisa ama-cyanides ukuze akhiqize izinto zamakhemikhali ezinjenge-oxides ne-ammonium ferrous sulfate. Phakathi kwazo, ama-ion ensimbi esindayo enza i-hydroxide precipitates, futhi ama-ion e-ferrocyanide namanye ama-ion esindayo enza usawoti oyinkimbinkimbi we-ferrocyanide.

• Indlela Ye-Ozone Oxidation: Ilungele ukwelapha i-cyanide encibilikisiwe - equkethe uketshezi olulahlwayo. Ngenani le-alkaline pH lika-11 - 12. i-ozone i-oxidize ama-cyanides ukuze akhiqize i-bicarbonate ne-nitrogen. Nakuba le ndlela ingakwazi ukususa ama-ferrocyanide complexes, inezinzuzo zokulula nokulula. Asikho isidingo sokuthenga nokuthutha amakhemikhali, futhi ijeneretha ye-ozone kuphela edingekayo ukwelapha i-cyanide - equkethe amanzi angcolile. Kodwa-ke, futhi inobubi bokusetshenziswa kwamandla aphezulu kanye nezindleko zokwelashwa eziphezulu. Ukuze kuxazululwe inkinga yezakhiwo ze-ferrocyanide, i-Tinker Air Force Base e-United States yathuthukisa inqubo ehlanganisiwe ye-ultraviolet photolysis kanye nendlela ye-ozone futhi yayihlola ngempumelelo. Kamuva, indlela efanayo ye-O3/photolysis nayo yasungulwa.

Ukuqinisekiswa Kwezokuthutha Nesitoreji

Kusixhumanisi sezokuthutha, sihlonyiswe ngezinto zokuthutha zamakhemikhali ayingozi kanye nezinqubo eziqinile zokulawula ezokuthutha ukuze siqinisekise ukuthi i-sodium cyanide ifika endaweni ngokuphephile kuyilapho sinciphisa umthelela endaweni ezungezile endleleni. Mayelana nokugcinwa, sinikeza izixazululo zesayensi yokugcina izinto kanye nezinsiza zokuvimbela izingozi ezifana nokuvuza ekungcoliseni inhlabathi nemithombo yamanzi. Esimeni sezimo ezingalindelekile, siphinde sibe nobuchwepheshe bokwelashwa kwezimo eziphuthumayo kanye namathimba angaphendula ngokushesha futhi anciphise ukulimala kwemvelo.

Shaanxi United Chemical uzibophezele ekusebenzisaneni ngokubambisana nozakwethu e-Kazakhstan ukuze bathole intuthuko eluhlaza nesimeme kuyilapho behlinzeka ngemikhiqizo yekhwalithi ephezulu ye-sodium cyanide. Sikholelwa ukuthi ngemizamo yethu, singakwazi ukufaka isandla ekuthuthukisweni kwezimboni zaseKazakhstan futhi sengeze isiqinisekiso sokuvikelwa kwemvelo kwendawo.
