Ama-crygenic uketshezi njenge-nitrogen ye-liquid (LN2), i-hydrogen ye-liquid (LH2), kanye ne-Liquefied gesi yemvelo (LNG) ebalulekile ezimbonini ezahlukahlukene, kusuka kuzicelo zezokwelapha ukukhiqizwa kwamandla. Ukuhamba kwalezi zinto zokushisa okuphansi kudinga amasistimu akhethekile okugcina amazinga okushisa awo abanda kakhulu futhi avikele ukuhwamuka. Enye yobuchwepheshe obusebenzayo kakhulu bokuhambisa uketshezi lwe-cryogenic Ipayipi elifakwe i-vacuum. Ngezansi, sizohlola ukuthi lezi zinhlelo zisebenza kanjani nokuthi kungani zibalulekile ekuthutha ngokuphepha uketshezi lwe-crygenic.

Inselelo yokuhambisa uketshezi lwe-cryogenic

Uketshezi lwe-Cryogenic lugcinwa futhi luhanjiswa emazingeni okushisa aphansi -150 ° C (-238 ° F). Emazingeni okushisa aphansi anjalo, ajwayele ukuhwamuka ngokushesha uma kuvezwa izimo ezikhona. Inselelo enkulu inciphisa ukudluliselwa kokushisa ukuze ugcine lezi zinto ezisesimweni sazo se-liquid ngesikhathi sokuhamba. Noma yikuphi ukwanda kwezinga lokushisa kungaholela ekuhlelweni okusheshayo, okuholela ekulahlekelweni komkhiqizo kanye nezingozi zokuphepha ezingaba khona.

I-Vacuum Insurated Pipeline: Isihluthulelo Sokuhamba Okusebenzayo

I-Vacuum Insurated Pipelines. Lawa mapayipi aqukethe izingqimba ezimbili: ipayipi elingaphakathi, eliphethe uketshezi lwe-cryogenic, nepayipi elingaphandle elifaka ipayipi elingaphakathi. Phakathi kwalezi zingqimba ezimbili kungukukhala, okusebenza njengesivila esifaka ukunciphisa ukushiswa kanye nemisebe. Le khasiIpayipi elifakwe i-vacuumUbuchwepheshe bunciphisa kakhulu ukulahleka okushisayo, ukuqinisekisa ukuthi uketshezi luhlala endaweni yokushisa edingekayo kulo lonke uhambo lwayo.

Isicelo ekuhambeni kwe-LNG

I-liquefied ger (LNG) ingumthombo odumile kaphethiloli futhi kufanele ihanjiswe emazingeni okushisa aphansi njengoba -162 ° C (-260 ° F).I-Vacuum Insurated PipelinesIsetshenziswa kabanzi kwizikhungo ze-LNG nasezikhawulweni zokuhambisa i-LNG kusuka emathangini okugcina kuya ezimisele noma kwezinye iziqukathi zokuhamba. Ukusetshenziswa kwama-VIP kuqinisekisa ukushiswa kokushisa okuncane, kunciphisa ukwakheka kwegesi ye-Bil-off (BOG) kanye nokugcina i-LNG esimweni sayo sokonga ngesikhathi sokulayisha nokulayisha.

I-Sydrogen ye-Liquid Hydrogen kanye ne-Liquid Nitrogen Trainstation

Ngokufanayo,I-Vacuum Insurated Pipelineszibalulekile ekuthuthweni kwe-liquid hydrogen (LH2) kanye ne-liquid nitrogen (LN2). Isibonelo, i-hydrogen ewuketshezi isetshenziswa kakhulu ekuhlolweni kwesikhala kanye nobuchwepheshe be-petrol cell. Iphuzu layo elisezingeni eliphansi kakhulu lika-253 ° C (-423 ° F) lidinga izinhlelo ezikhethekile zokuhamba. Ama-VIP ahlinzeka ngesisombululo esifanele, avumela ukuhamba okuphephile nokusebenzayo kwe-LH2 ngaphandle kokulahleka okukhulu ngenxa yokudluliswa kokushisa. I-Nitrogen ewuketshezi, esetshenziswa kabanzi kwizicelo zezokwelapha nezezimboni, futhi izinzuzo ezivela kuma-VIP, ziqinisekisa izinga lokushisa layo kulo lonke inqubo.

Isiphetho: Indima yeI-Vacuum Insurated Pipelines Ngokuzayo kwama-cryogenics

Njengoba izimboni ziyaqhubeka nokuthembela ku-crygenic ketshezi, I-Vacuum Insurated Pipelinesuzodlala indima ebaluleke kakhulu ekuqinisekiseni ukuthutha kwabo okuphephile nokusebenzayo. Ngamandla abo okunciphisa ukudluliswa kokushisa, ukuvimbela ukulahleka komkhiqizo, futhi athuthukise ukuphepha, ama-VIP ayingxenye ebalulekile emkhakheni okhulayo we-crygenic. Ukusuka ku-LNG kuya ku-hydrogen ye-liquid, lobu buchwepheshe buqinisekisa ukuthi uketshezi lokushisa oluphansi lungahanjiswa ngomthelela omncane emvelo kanye nokusebenza kahle okukhulu.
