Inqubekelaphambili ekukhiqizweni kwe-sodium cyanide kusuka ekuqhekekeni kwamafutha alula e-China

Isingeniso

The Inqubo yokuqhekeka kwamafutha alula ngoba I-sodium cyanide ukukhiqiza sekuyisikhathi eside kungenye yezindlela eziyinhloko eShayina, okungaphezu kuka-60% wengqikithi yokukhiqiza I-Sodium Cyanide ezweni. Eminyakeni yamuva nje, ngemizamo kahulumeni waseShayina eqinisiwe ekukhiqizeni amakhemikhali ayingozi kanye nokwengamela imvelo, kube nokuthuthuka okuphawulekayo kukho kokubili izinga lezindawo zokukhiqiza kanye nobungane bemvelo balolu hlelo lokukhiqiza.

Intuthuko Esikalini Sokukhiqiza kanye Nobungani Nemvelo

Okukhudlwana - Izinsiza Zokukhiqiza Isikali

Isilinganiso sokukhiqiza senqubo yokuqhekeka kawoyela okhanyayo besilokhu sanda. Izitshalo ezisezingeni elikhudlwana ziyakhiwa, okungagcini nje ngokukhuphula ukusebenza kahle kokukhiqiza kodwa futhi kuvumela ukuphathwa okungcono kwezinsiza. Lokhu kufakwa kwezikali ezinkulu kuklanywe ngemiqondo yobunjiniyela ethuthukisiwe, okuqinisekisa inqubo yokukhiqiza ezinzile neqhubekayo. Isibonelo, izitshalo zesimanje zinamagumbi okusabela athuthukisiwe akwazi ukuphatha amanani amakhulu kawoyela okhanyayo nama-reactants, okuholela ekuvunweni okuphezulu i-sodium cyanide.

Ubungane Bemvelo Okuthuthukisiwe

Ukunciphisa "Imfucuza Emithathu"

Ngokwamukelwa kobuchwepheshe obuthuthukisiwe kanye nemishini, inani "lemfucumfucu emithathu" (igesi engcolile, amanzi angcolile, kanye nemfucumfucu eqinile) eyenziwa ngesikhathi sokukhiqiza liye lancipha kakhulu. Ama-reactors esizukulwane esisha afakelwe igesi ethuthukisiwe - amasistimu okuhlanza. Lezi zinhlelo zingasusa ngempumelelo amagesi ayingozi njenge-hydrogen i-cyanide nama-nitrogen oxides aphuma exhaust gas, enciphisa ukungcoliswa komoya. Mayelana nokwelashwa kwamanzi angcolile, ukuhlunga okuthuthukisiwe nezindlela zokwelashwa ngamakhemikhali zisetshenziswa. Amanzi angcolile aphuma ohlelweni lokukhiqiza aphathwa ukuze ahlangabezane nezindinganiso eziqinile zemvelo ngaphambi kokuba akhishwe, okunciphisa umthelela emithonjeni yamanzi. Maqondana nemfucuza eqinile, kusungulwe izinqubo ezintsha ukuze zigaywe kabusha noma zilahlwe ngokuphephile imikhiqizo, okuqhubeka nokunciphisa umkhondo wemvelo.

Ukulondolozwa Kwezinsiza

Ukongiwa kwezinsiza sekuyisici esibalulekile senqubo yokuqhekeka kawoyela okhanyayo eyenziwe ngcono. Ukushisa okuthuthukisiwe - amasistimu okubuyisela afakwe ezitshalweni zokukhiqiza zesimanje. Lawa masistimu angathwebula futhi asebenzise kabusha ukushisa okukhiqizwa phakathi nenqubo yokuqhekeka, okunciphisa ukusetshenziswa kwamandla sekukonke. Ukwengeza, kusetshenziswa ama-catalyst asebenza kahle kakhulu, angasheshi nje kuphela izinga lokusabela kodwa futhi athuthukise izinga lokusetshenziswa kwezinto ezingavuthiwe. Njengomphumela, uwoyela omncane okhanyayo nezinye izinto ezisabelayo ziyadingeka ukuze kukhiqizwe inani elifanayo le-sodium cyanide, kuzuzwe ukonga okubalulekile kwensiza.

Umthelela Wemithetho Eqinile

Ukuqiniswa kwemithethonqubo yokuphepha kanye nemvelo kube yiwona mandla aqhuba lezi ntuthuko. Uhulumeni waseShayina ukhiphe uchungechunge lwezinqubomgomo nezindinganiso zokuqinisekisa ukukhiqizwa okuphephile kwamakhemikhali ayingozi kanye nokuvikela imvelo. Amabhizinisi okukhiqiza kudingeka ukuthi atshale imali kubuchwepheshe obuthuthukile namathuluzi ukuze ahlangabezane nalezi zidingo zokulawula. Ukwehluleka ukuthobela imithetho kungaholela ezijezisweni ezinzima, ezihlanganisa izinhlawulo, ukumiswa kokukhiqiza, noma ngisho nokuvalwa kwebhizinisi. Ngakho-ke, ukuze kugcinwe ukuncintisana kanye nentuthuko yesikhathi eside, amabhizinisi akwamukele ngenkuthalo ukuthuthukiswa kwezobuchwepheshe kanye nokwenza ngcono izinqubo.

Isiphetho

Sengiphetha, uwoyela ukukhanya ukuqhekeka inqubo for Ukukhiqizwa kwe-sodium cyanide e-China iye yaba nezinguquko eziphawulekayo eminyakeni yamuva. Ukuthuthukiswa kwesikali sokukhiqiza kanye nobungane bemvelo, kanye nokongiwa kwezinsiza, akuzona nje kuphela izimpendulo ezicindezelweni zokulawula kodwa futhi nokubonakaliswa kokuphishekela kwemboni intuthuko esimeme. Njengoba ubuchwepheshe buqhubeka nokuthuthuka kanye nezimfuneko zokulawula ziba namandla, kulindeleke ukuthi le nqubo yokukhiqiza iqhubeke nokuvela, ifinyelele amazinga aphezulu okuphepha, ukuvikelwa kwemvelo, kanye nokusetshenziswa kwezinsiza.
