Shaanxi United Chemical: Ukubonelela ngezisombululo zeSodium Cyanide eziluhlaza zeKazakhstan

Kwintsimi yokubonelela ngemveliso yeekhemikhali, uShaanxi United Chemical ibisoloko iphambili kwishishini elinomfanekiso oqeqeshiweyo nonoxanduva. Ngoku, sinelunda kakhulu ukuba sikwazi ukubonelela ngomgangatho ophezulu Isodium cyanide iimveliso zaseKazakhstan.

Sodium i-cyanide, njengesixhobo esibalulekileyo sekhemikhali ekrwada, sisetyenziswa kakhulu kwiindawo ezininzi zoshishino, ngakumbi kwimigodi yegolide kunye neshishini lokuxhamla. Nangona kunjalo, ngenxa yeempawu zayo ezikhethekileyo, ilawulwa ngokungqongqo ngurhulumente waseTshayina. Sikwanolwazi olunzulu ngokwenzakala okunokubakho kwe sodium cyanide kokusingqongileyo. Ukuba i-cyanide - equlathe amanzi amdaka aveliswa kumbiwa wegolide kunye nenkqubo yokuzuza uncedo ayiphathwa kakuhle, iya kuba yingozi enkulu kwindalo esingqongileyo. I-cyanide kumanzi amdaka ezityalo zegolide ze-cyanidation zichongwa ngokubunjwa kwe-ore kunye neemeko zokusebenza. Ukongeza kwi-cyanide, ikwaqulethe izinto zekhemikhali ezifana ne-thiocyanate. Uninzi lwezi thiocyanates zivela kwinkqubo ye-aeration kwimveliso okanye ukusabela phakathi kwe-cyanide kunye ne-athomu yesulfure engazinzanga ngexesha lokuhlamba. Ngaphezu koko, i-cyanide-equlethe amanzi amdaka iqulethe isixa esikhulu se-cyanide yensimbi enetyhefu kakhulu kwaye iicyanides. Ngoko ke, Shaanxi United Chemical ayingomthengisi wemveliso kuphela kodwa ikwayingcali ye Ukukhuselwa kwendalo.

Izinto eziluncedo zokuKhuselwa kokusiNgqongileyo

Ngokubhekiselele kukhuseleko lokusingqongileyo, sineengenelo ezibalulekileyo. Inkampani ityala imali eninzi yezibonelelo kuphando lwetekhnoloji kunye nophuhliso, kwaye ibonelela ngenkxaso yobugcisa ebanzi kwiingxaki ezinokubakho zokusingqongileyo ezinokuvela ngexesha lemveliso, ukuthutha, ukugcinwa kunye nokusetyenziswa Isodium cyanide. Iqela lethu lobuchwephesha linokuncedisa amashishini asekhaya eKazakhstan ukuseka inkqubo epheleleyo yolawulo lokusingqongileyo kunye nokunciphisa isizukulwana esingcolisekileyo esivela kumthombo. Umzekelo, kwinkqubo yokuvelisa, samkela itekhnoloji ephucukileyo ye-green synthesis ukuphucula ukusetyenziswa kwezinto ezikrwada kunye nokunciphisa ukukhutshwa kwenkunkuma.

Iindlela zoNyango lweCyanide - equlathe Amanzi amdaka

Kunyango lwe-cyanide-equlathe amanzi amdaka kwimigodi yegolide kunye neshishini lokuxhamla, sinobuchule obuhlukeneyo beendlela ezivuthiweyo nezisebenzayo:

• Indlela ye-Alkaline yeChlorination: Le yindlela eqhelekileyo yokutshabalalisa IiCyanides kumanzi amdaka ezityalo ze-cyanidation zegolide kwaye isetyenziswa kakhulu kunyango lwamanzi amdaka kwizityalo ze-cyanide electroplating, izityalo zegolide ze-cyanidation, izityalo zegolide ze-cyanidation kunye nezinye iiyunithi. Umthetho-siseko wayo kukusebenzisa i-chlorine elulwelo, igesi yeklorin okanye umgubo oxutyiweyo ukwenza i-cyanide emanzini amdaka ibe zizinto ezingeyotyhefu ezifana nekharbon diokside kunye nenitrogen.

• I-Sulfur Dioxide - iNdlela yokuNxibelela umoya: Eyaziwa nangokuthi indlela ye-InCo, yaphuhliswa yiNkampani ye-American InCo Metals ekuqaleni kwe-1980. Le ndlela isebenzisa i-sulphur dioxide kunye nomoya njenge-oxidants ukukhupha iicyanides emanzini amdaka phantsi kwemeko ye-copper - ion catalyst, evelisa i-bicarbonate kunye ne-ammonium ferrous sulfate. Ayinakususa kuphela i-cyanide ions yamahhala, i-hydrogen ye-molecular kunye ne-cyanides eyinkimbinkimbi, kodwa iphinde isuse i-ferrocyanide complexes enzima ukuyisusa ngendlela ye-chlorination, okwenza ukuba amanzi amdaka aphathwe ahlangabezane nemigangatho yokukhupha.

• Indlela ye-Hydrogen Peroxide: Ilungele ukunyanga i-cyanide ephantsi-equlethe amanzi amdaka. Ngaphantsi kwesenzo sobhedu - i-ion catalyst kwixabiso le-alkaline pH ye-10 - 11. i-hydrogen peroxide i-oxidize i-cyanides ukuvelisa izinto zekhemikhali ezifana nee-oxides kunye ne-ammonium ferrous sulfate. Phakathi kwazo, ii-ion zensimbi ezinzima zenza i-hydroxide precipitates, kwaye i-ion ye-ferrocyanide kunye nezinye ii-ion zetsimbi ezinzima zenza iityuwa eziyinkimbinkimbi ze-ferrocyanide.

• Indlela ye-Ozone oxidation: Ilungele ukunyanga icyanide edilute kakhulu - equlethe ulwelo olulahlwayo. Kwixabiso le-alkaline pH ye-11 - 12. i-ozone i-oxidize i-cyanides ukuvelisa i-bicarbonate kunye ne-nitrogen. Nangona le ndlela ayikwazi ukususa i-ferrocyanide complexes, ineenzuzo zokulula kunye nokulula. Akukho mfuneko yokuthenga kunye nokuthutha iikhemikhali, kwaye kuphela i-ozone generator efunekayo ukunyanga i-cyanide - equkethe amanzi angcolileyo. Nangona kunjalo, ikwanayo nokungalungi kokusetyenziswa kwamandla aphezulu kunye neendleko eziphezulu zonyango. Ukucombulula ingxaki ye-ferrocyanide complexes, i-Tinker Air Force Base e-United States yavelisa inkqubo edibeneyo ye-ultraviolet photolysis kunye nendlela ye-ozone kwaye yavavanya ngempumelelo. Kamva, indlela efanayo ye-O3/photolysis nayo yaphuhliswa.

Ingqinisekiso yezoThutho kunye noGcino

Kwikhonkco lezothutho, sixhotyiswe ngezixhobo zothutho zeekhemikhali ezinobungozi kunye neenkqubo ezingqongqo zolawulo lwezothutho ukuqinisekisa ukuba i-sodium cyanide ifika kwindawo ekuyiwa kuyo ngokukhuselekileyo ngelixa inciphisa impembelelo yokusingqongileyo endleleni. Ngokubhekiselele kugcino, sibonelela ngezisombululo zogcino lwenzululwazi kunye nezibonelelo zokuthintela iingozi ezinjengokuvuza ekungcoliseni umhlaba kunye nemithombo yamanzi. Kwimeko yeemeko ezingalindelekanga, sikwanabo ubuchwepheshe bonyango olungxamisekileyo kunye namaqela anokuthi aphendule ngokukhawuleza kwaye anciphise umonakalo wokusingqongileyo.

Shaanxi United Chemical uzibophelele ekusebenzeni ngesandla kunye namaqabane eKazakhstan ukuphumeza uphuhliso oluluhlaza kunye noluzinzileyo ngelixa ubonelela ngemveliso ephezulu yesodium cyanide. Sikholelwa ukuba ngeenzame zethu, sinokuba negalelo kuphuhliso lweshishini laseKazakhstan kwaye songeze isiqinisekiso sokhuseleko lwendawo yendawo.
