Iyini igesi ye-oxygen yezokwelapha? Yiziphi izinyathelo zokuphepha zokugcinwa nokusetshenziswa

Igesi ye-oxygen yezokwelapha igesi esetshenziselwa izimo eziphuthumayo zezokwelapha kanye nokwelapha okuyisizayo kwezinye izifo, ngobumsulwa obungu-≥ 99.5% futhi ihlangabezana nezindinganiso ezithile ze-acidity, i-carbon monoxide, i-carbon dioxide, namanye ama-gaseous oxides. Igesi ye-oksijini yezokwelapha ihlukaniswa kakhulu nomkhathi ngokuhlukana kwe-cryogenic, futhi ibhekana nezinqubo zokucindezelwa okuningi, ukupholisa, kanye ne-distillation ukuze kukhishwe uthuli, ukungcola, i-carbon monoxide, i-carbon dioxide, nomhwamuko wamanzi.

Lapho ugcina futhi usebenzisa igesi ye-oksijeni yezokwelapha, kuyadingeka ukulandela izinyathelo zokuphepha ezibalulekile. Okokuqala, ngenxa yokuvutha okunamandla kwegesi ye-oxygen yezokwelapha, kuyadingeka ukugcina ibanga kusuka ezintweni ezivuthayo ezifana namafutha nezimpushana eziphilayo ukuze kugwenywe ukuvutha noma ukuqhuma. Okwesibili, ngesikhathi sokugcinwa, ukuphatha, kanye nokusetshenziswa kwamasilinda egesi ye-oxygen, kuyadingeka ukulandela ngokuqinile izinqubo zokusebenza zokuphepha. Isibonelo, amasilinda egesi yomoya-mpilo kufanele abekwe aqonde futhi kuthathwe izinyathelo zokunqanda ukusikisela, futhi izindawo zokugcina kufanele zigcinwe kude namalangabi avulekile kanye neminye imithombo yokushisa. Ngesikhathi sokuthutha, kufanele ilayishwe futhi yehliswe ngokucophelela ukuze kugwenywe ukushelela, ukugingqika nokushayisana, futhi izimoto zokuhamba ezingcoliswe uwoyela namafutha akufanele zisetshenziswe. Lapho kusetshenziswa, izinyathelo zokulwa nokunikeza iseluleko kufanele zithathwe, izinsiza zokuphepha kufanele zinikezwe, ukungqongqoza noma ukushayisana kuvinjelwe ngokuqinile, futhi ukuba seduze kwemithombo yokushisa, amabhokisi kagesi, nezintambo kufanele kugwenywe.

Ngaphezu kwalokho, kunomehluko ocacile phakathi kwegesi ye-oksijeni yezokwelapha kanye negesi ye-oxygen yezimboni. Igesi ye-oxygen yezimboni idinga kuphela ukuhlanzeka kwegesi yomoya-mpilo futhi ingase ibe namagesi ayingozi njenge-carbon monoxide ne-methane eyeqa izinga, kanye namazinga aphezulu omswakama, amagciwane, nothuli. Ngakho-ke, akuvunyelwe ngokuphelele ukusebenzisa igesi ye-oxygen yezimboni ngezinjongo zokwelapha.
