Ukuminyana kweMethanol: Ukuhlaziya Okubanzi kanye Nezimo Zokusebenza
I-Methanol, njengenhlanganisela ebalulekile yezinto eziphilayo, inezinhlobonhlobo zezicelo embonini yamakhemikhali. Ukuqonda izici ezibonakalayo ze-methanol, njengokuminyana kwe-methanol, kubalulekile ekukhiqizeni amakhemikhali, ekugcinweni nasekuthuthweni. Kulesi sihloko, sizoxoxa ngokuningiliziwe ngencazelo ye-methanol density, izici zayo ezithonya kanye nokubaluleka kwayo ekusebenziseni okungokoqobo.
Umqondo oyisisekelo wokuminyana kwe-methanol
Ukuminyana kwe-methanol yisisindo se-methanol ngeyunithi ngayinye, ngokuvamile evezwa ngamagremu ku-cubic sentimitha (g/cm³) noma amakhilogremu ku-cubic meter ngayinye (kg/m³). Ngaphansi kwezimo ezijwayelekile, ukuminyana kwe-methanol ku-20°C cishe ku-0.7918 g/cm³. Lelivelu lokuminyana lenza i-methanol ibelula kunamanzi (enesisindo esingaba ngu-1 g/cm³), okusho ukuthi ezinhlelweni eziningi zisho izidingo zokuphatha nokugcinwa okuhlukile.
Izinto ezithinta ukuminyana kwe-methanol
Ithonya lokushisa
Izinga lokushisa lingenye yezinto eziyinhloko ezithinta ukuminyana kwe-methanol. Njengoba izinga lokushisa likhuphuka, ukunyakaza kwamangqamuzana e-methanol kuyanda, umthamo uyakhula futhi ukuminyana kuyehla. Ngokuphambene, lapho izinga lokushisa lincipha, ukunyakaza kwamangqamuzana kuncipha futhi ukuminyana kwe-methanol kuyanda. Ngakho-ke, ekusebenzeni, izinkampani zamakhemikhali zivame ukulungisa ukuklama nomthamo wemishini yokugcina ngokuvumelana nezinga lokushisa elizungezile.
Umthelela wokuhlanzeka
Ukuhlanzeka kwe-methanol nakho kuthinta ngqo ukuminyana kwayo. Emkhiqizweni wezimboni, i-methanol ingase ixutshwe nezinsalela zamanzi noma okunye ukungcola, okuvame ukuba nzima noma kube lula kune-methanol, ngaleyo ndlela kuguqule ukuminyana okuphelele kwe-methanol. Ngakho-ke, ukulawula ukuhlanzeka kwe-methanol kubalulekile ezimeni zohlelo lokusebenza ezizwelayo ukuminyana.
Izimo zohlelo lokusebenza zokuminyana kwe-methanol
Izicelo ku Chemical Production
Idatha enembile ngokuminyana kwe-methanol ibalulekile ekudoseni nasekulawuleni ukusabela ngesikhathi sokukhiqizwa kwamakhemikhali. Ukusabela kwamakhemikhali okuningi kunezidingo eziqinile zokuhlangana kwama-reactants, okuvame ukunqunywa ukuminyana. Isibonelo, ekuphenduleni kwe-methanol-to-formaldehyde, izilinganiso ezinembile zokuminyana zisiza ukuqinisekisa ukusebenza kahle kokusabela kanye nokuhlanzeka komkhiqizo.
Izicelo endaweni yokugcina nezokuthutha
Ukuminyana kwe-methanol kunomthelela ekwakhiweni kwamathangi okugcina neziqukathi zokuthutha. Ngesikhathi sokuthutha, ukuminyana okuphansi kusho ukuthi i-methanol inesisindo esincane ngevolumu efanayo, okunganciphisa izindleko zokuthutha. Ukuqonda ukuminyana kwe-methanol kusiza futhi ekwandiseni ukwakheka kwezinto zokugcina ukuze kuqinisekiswe ukugcinwa okuphephile nokuvikela ukuvuza.
Ngokufigqiwe
Ukuminyana kwe-methanol akuyona nje impahla eyisisekelo eyisisekelo, kodwa futhi ibalulekile ukuze isetshenziswe ekukhiqizeni amakhemikhali, ekugcinweni nasekuthuthweni. Ukuqonda nokusebenzisa kahle idatha yokuminyana kwe-methanol akuthuthukisi ukusebenza kahle kokukhiqiza kuphela, kodwa futhi kulawula ngempumelelo izindleko futhi kuqinisekise ukuphepha kokusebenza. Kubasebenzi bemboni yamakhemikhali, ulwazi lokuminyana kwe-methanol luyingxenye ebalulekile yamakhono abo ochwepheshe.
