Ulwelo lwe-Cryogenic olufana ne-nitrogen engamanzi (LN2), i-hydrogen engamanzi (LH2), kunye ne-liquefied natural gas (LNG) zibalulekile kumashishini ahlukeneyo, ukusuka kwizicelo zonyango ukuya kwimveliso yamandla. Ukuthuthwa kwezi zinto zinobushushu obuphantsi kufuna iinkqubo ezikhethekileyo zokugcina ubushushu bazo obubanda kakhulu kwaye zithintele ukuvela komphunga. Enye yezona teknoloji zisebenzayo zokuthutha ulwelo lwe-cryogenic yi umbhobho ogqunywe ngevacuum. Ngezantsi, siza kuphonononga ukuba ezi nkqubo zisebenza njani kwaye kutheni zibalulekile ekuthutheni ngokukhuselekileyo ulwelo lwe-cryogenic.

Umceli mngeni wokuThutha i-Cryogenic liquids

Ulwelo lweCryogenic lugcinwa kwaye luthuthwe kumaqondo obushushu angaphantsi kwe -150°C (-238°F). Kumaqondo obushushu aphantsi ngolo hlobo, athanda ukumka ngokukhawuleza xa evezwe kwiimeko ezingqongileyo. Owona mceli mngeni mkhulu kukunciphisa ukuhanjiswa kobushushu ukugcina ezi zinto zikwimo yazo engamanzi ngexesha lothutho. Nakuphi na ukunyuka kweqondo lokushisa kunokubangela ukuqhuma ngokukhawuleza, okukhokelela ekulahlekeni kwemveliso kunye nobungozi obunokhuseleko.

Umbhobho weVacuum Insulated: Isitshixo soThutho oluLungileyo

Vacuum imibhobho egqunyiweyo(VIPs) sisisombululo esibalulekileyo sokuthutha ulwelo lwe-cryogenic kumgama omde ngelixa unciphisa ukuhanjiswa kobushushu. Le mibhobho inemigangatho emibini: umbhobho ongaphakathi, ophethe ulwelo lwe-cryogenic, kunye nombhobho ongaphandle ovale umbhobho wangaphakathi. Phakathi kwala maleko mabini kukho i-vacuum, esebenza njengesithintelo sokukhusela ukunciphisa ukuqhutyelwa kobushushu kunye nemitha. Iumbhobho ogqunywe ngevacuumitekhnoloji inciphisa kakhulu ilahleko yobushushu, iqinisekisa ukuba ulwelo luhlala kubushushu obufunekayo kulo lonke uhambo lwayo.

Isicelo kwi-LNG Transportation

I-Liquefied natural gas (LNG) ngumthombo wamafutha odumileyo kwaye kufuneka ithuthwe kumaqondo obushushu asezantsi njenge -162°C (-260°F).Vacuum imibhobho egqunyiweyozisetyenziswa kakhulu kumaziko e-LNG kunye neetheminali zokuhambisa i-LNG ukusuka kwiitanki zokugcina ukuya kwiinqanawa okanye ezinye izikhongozeli zothutho. Ukusetyenziswa kwee-VIP kuqinisekisa ukungena kobushushu obuncinci, ukunciphisa ukubunjwa kwe-boil-off gas (BOG) kunye nokugcina i-LNG kwindawo yayo edibeneyo ngexesha lokulayisha nokukhupha imisebenzi.

I-Liquid Hydrogen kunye ne-Liquid Nitrogen Transportation

Ngokufanayo,vacuum imibhobho egqunyiweyozibalulekile kuthutho lwe-hydrogen engamanzi (LH2) kunye nenitrogen engamanzi (LN2). Umzekelo, i-hydrogen engamanzi iqhele ukusetyenziswa kuphononongo lwe-space kunye ne-fuel cell technology. Indawo yayo yokubila ephantsi kakhulu engu -253°C (-423°F) ifuna iinkqubo zothutho ezikhethekileyo. Ii-VIP zibonelela ngesisombululo esifanelekileyo, esivumela ukunyakaza okukhuselekileyo nokusebenzayo kwe-LH2 ngaphandle kokulahlekelwa okukhulu ngenxa yokutshintshwa kobushushu. I-nitrogen yolwelo, esetyenziswa ngokubanzi kwizicelo zonyango nakwimizi-mveliso, nayo izuza kwi-VIPs, iqinisekisa ubushushu bayo obuzinzile kuyo yonke inkqubo.

Isiphelo: Indima yeImibhobho yeVacuum Insulated kwiKamva leCryogenics

Njengoko amashishini eqhubeka nokuxhomekeka kulwelo lwe-cryogenic, vacuum imibhobho egqunyiweyoziya kudlala indima ebalulekileyo ekuqinisekiseni uthutho lwabo olukhuselekileyo nolusebenzayo. Ngokukwazi kwabo ukunciphisa ukuhanjiswa kobushushu, ukuthintela ukulahleka kwemveliso, kunye nokwandisa ukhuseleko, ii-VIPs ziyinxalenye ebalulekileyo kwicandelo elikhulayo le-cryogenic. Ukusuka kwi-LNG ukuya kwi-hydrogen engamanzi, obu buchwephesha buqinisekisa ukuba ulwelo olunobushushu obuphantsi bunokuthuthwa ngempembelelo encinci yokusingqongileyo kunye nokusebenza okuphezulu.
