Isikhwama Sepulasitiki Sokupakisha I-Aluminium Sebhontshisi Yekhofi Esine-Tin Tie

Izikhwama zobhontshisi wekhofi othosiwe (impuphu) zinezindlela ezahlukahlukene zokupakisha. Njengoba ubhontshisi wekhofi uzokhiqiza i-carbon dioxide ngokwemvelo ngemva kokuthosa, ngakho-ke uma iphakethe liqondile lizobangela umonakalo wokupakisha kalula, futhi uma liqhubeka isikhathi eside livezwa emoyeni kuzobangela ukulahlekelwa yiphunga kumafutha obhontshisi wekhofi. Ngoba ukuminyana kwezithako kungabangela ukuwohloka kwekhwalithi. Ngakho-ke, indlela yokupakisha ubhontshisi wekhofi (impuphu) ibaluleke kakhulu.

Ungayixazulula kanjani inkinga? Ngokufaka ivalvu yendlela eyodwa esikhwameni sekhofi, kuvumela i-carbon dioxide ekhiqizwayo ukuba iphume, kodwa ivimbele ukungena komoya wangaphandle. Kuvimbela ubhontshisi bekhofi ekushiseni, futhi kugcina iphunga likabhontshisi ngempumelelo. Ukupakisha okunjalo kungagcinwa izinyanga ezifika kweziyisithupha. Kukhona futhi amanye amakhofi apakishwe ngemigodi yokungenisa umoya, okungukuthi, kwenziwa imigodi yokungenisa umoya kuphela esikhwameni sokupakisha ngaphandle kokufaka ivalvu yendlela eyodwa, ukuze uma i-carbon dioxide ekhiqizwa ubhontshisi wekhofi isiphelile, umoya wangaphandle uzongena esikhwameni, futhi ubangele ukushisisa, ngakho-ke isikhathi sokusebenza sincishiswa kakhulu.

Izinhlobo ezahlukene zezikhwama zekhofi zinezinto ezihlukene. Ngokuvamile, izinto zokupakisha ubhontshisi obuluhlaza zilula kakhulu futhi ziyizinto ezijwayelekile zesaka. Azikho futhi izidingo zezinto ezikhethekile zokupakisha ikhofi okusheshayo, okusebenzisa ngokuyisisekelo izinto zokupakisha ukudla ezijwayelekile. Kodwa ukupakishwa kobhontshisi bekhofi (impuphu) kuvame ukusebenzisa izinto ezihlanganisiwe zepulasitiki ezingacacile noma izinto ezihlanganisiwe zephepha le-kraft ezinobungani nemvelo ngenxa yezidingo zokulwa ne-oxidation.

Ukuze kuphinde kusetshenziswe ukuvala, kuzofakwa ibha yethini emphethweni wokuvala. Njengentambo yensimbi, inokusebenza okuhle kakhulu kokugoba nokuguqula isimo ngesenzo samandla angaphandle, ukulahlekelwa isenzo samandla angaphandle nokungaphindi, ukugcina isimo esikhona singashintshi, futhi ingahlanganiswa kahle nesikhwama sekhofi ukuze kufezwe umphumela wokuvala wekhwalithi ephezulu. Umugqa wokuvala isikhwama sekhofi osebenzayo usetshenziswa kakhulu emlonyeni wesikhwama sekhofi, ongalungisa umlomo wesikhwama, futhi udlale indima yokuvala, ukugcina kusha futhi kungangeni umswakama, nokuvimbela izinambuzane ukuthi zingangeni.
