Sekuphele cishe inyanga kusukela i-United States iyeke ukwethulwa kwamabhaluni esimo sezulu avela eDenver's Central Park. IDenver ingenye yezindawo ezingaba yi-100 e-US ezikhipha amabhaluni esimo sezulu kabili ngosuku, eyayeka ukundiza ekuqaleni kukaJulayi ngenxa yesimo sezulu emhlabeni jikelele.i-heliumukushoda. I-United States ibilokhu ikhipha amabhaluni kabili ngosuku kusukela ngo-1956.

Idatha eqoqwe ngamabhaluni esimo sezulu ivela kumaphakheji ezinsimbi abizwa ngokuthi ama-radiosondes. Uma selikhishwe, ibhaluni lindiza liye e-stratosphere engezansi futhi lilinganise ulwazi olufana nokushisa, umswakama, isivinini somoya kanye nesiqondiso. Ngemva kokufinyelela ukuphakama okungamamitha ayi-100,000 noma ngaphezulu, ibhaluni liyavela bese iparachute ibuyisela i-radiosonde phezulu.

Nakuba ukushoda kwe-helium lapha kungakathuthuki, i-United States isesimeni sokuntuleka kwe-carbon dioxide futhi.

Izimpahla eziqinile nomaikhabhoni dayoksayidiUkuntuleka kokunikezwa kuyaqhubeka kuthinta amabhizinisi kulo lonke elase-US, futhi isimo asibonakali siba ngcono esikhathini esifushane, njengoba ingcindezi iqhubeka nokuzwakala e-US ezinyangeni ezimbalwa ezizayo, kanti eningizimu-mpumalanga naseningizimu-ntshonalanga ye-US kukholakala ukuthi yiyona embi kakhulu.

Ngokuphathelene nemboni yezokungenisa izihambi,ikhabhoni dayoksayidiisetshenziswa kabanzi njenge-refrigerant embonini yokudla neziphuzo, kodwa futhi nasekupakishweni kwe-atmosphere modified (MAP) ukuze kwandiswe isikhathi sokuphila kweshelufu kanye neziphuzo ezine-carbonated, kanti iqhwa elomile (i-solid carbon dioxide) lisetshenziswa kakhulu ekulethweni ekhaya. Uma kukhulunywa ngokuqandisa ukudla, lo mkhuba uye wachuma ngesikhathi sobhubhane lwe-coronavirus.

Kungani ukungcola kuthinta izimakethe manje kunanini ngaphambili

Ukungcoliswa kwegesi kubhekwa njengembangela enkulu yokuntuleka kokunikezwa kwempahla. Ukwenyuka kwamanani kawoyela negesi kwenza ukusetshenziswaI-CO2ukuze i-EOR ikhange kakhulu. Kodwa imithombo eyengeziwe inezinto ezingcolisayo, kanti ama-hydrocarbon afaka phakathi i-benzene athinta ubumsulwa be-ikhabhoni dayoksayidi, futhi izimpahla ziyancipha ngoba akubona bonke abahlinzeki abangakwazi ukuhlunga ukungcola.
Kuyaqondakala ukuthi ezinye izitshalo esifundeni manje kumele zibe nokuhlanza okwanele kwangaphambi kokuphela ukuze zibhekane nokungcola, kodwa ezinye izitshalo ezindala ziyazabalaza ukuhlangabezana noma ukuqinisekisa izidingo ze-International Association of Beverage Technology.

Ukuvalwa okwengeziwe kwefektri kuzothinta ukunikezwa kwempahla emasontweni azayo

HopewellI-CO2Isitshalo iLinde plc eVirginia, e-USA, naso sihlelwe ukuvala ngenyanga ezayo (Septhemba 2022). Kubikwa ukuthi umthamo waso wonke ungamathani ayi-1,500 ngosuku. Ukuvalwa kwezitshalo okwengeziwe emasontweni azayo kusho ukuthi izinto zingase zibe zimbi kakhulu ngaphambi kokuba zibe ngcono, okungenani ezinye izitshalo ezincane ezine zivala noma zihlela ukuvala ezinsukwini ezingama-60 ezizayo.
