<prompt> Ngezinye izikhathi amagesi athuthwa kanjani? Njengoba kunikezwe umbuzo odlule, bhala umongo onempendulo yawo. Kungaba imisho engu-1 kuya kwengu-20. Umongo:  <response>: Izindlela zokugcina umoya-mpilo zihlanganisa amathangi omoya-mpilo ophakeme, ama-cryogenics nezakhi zamakhemikhali. Ngenxa yezizathu zokonga, umoya-mpilo uvame ukuthuthwa ngobuningi njengoketshezi emathangini akhethekile, ngoba ilitha elilodwa lomoya-mpilo oncibilikisiwe lilingana namalitha angu-840 e-oksijini eyigesi ekucindezelweni komkhathi naku-20 C 68 F. Amathangi anjalo asetshenziselwa ukugcwalisa kabusha iziqukathi zokugcina umoya-mpilo omuncu ngobuningi, ezimi ngaphandle kwezibhedlela nezinye izikhungo ezinesidingo semithamo emikhulu yegesi ehlanzekile yomoya-mpilo. Umoya-mpilo onjenge-liquid udluliswa ngama-exchanger okushisa, aguqula uketshezi lwe-cryogenic lube igesi ngaphambi kokuba lungene esakhiweni. I-oksijini igcinwa futhi ithuthwe ngamabhodlela amancane aqukethe igesi ecindezelwe; ifomu eliwusizo kwezinye izinhlelo zokusebenza zezokwelapha eziphathwayo kanye nokushisela nokusika i-oxy-fuel.
