Lub hauv paus ntawm cryogenic huab cua sib cais yog kom liquefy huab cua ntawm qhov kub thiab txias. Nws lub voj voog zoo tagnrho suav nrog compression, expansion (refrigeration) thiab reheating txheej txheem. Lub voj voog Linde yooj yim hauv daim ntawv thov muaj xws li compression, reheating thiab throttling txheej txheem. Kev sib cais ntawm huab cua yog ua tiav hauv ntauwd distillation, yog li tsim plaub yam tseem ceeb: compression, tub yees, reheating thiab distillation. Raws li qhov tshwm sim, cov txheej txheem kev sib cais ntawm huab cua cryogenic kuj tseem tsim los ntawm plaub lub qauv: cua compression thiab pretreatment, tub yees, hloov pauv kub thiab distillation. Ntawm lawv, lub koom haum daim ntawv ntawm tub yees, kev sib pauv cua sov thiab distillation modules yog hloov tau thiab hloov tau, uas dhau los ua qhov kev txiav txim siab ntawm cov txheej txheem sib txawv ntawm huab cua.
Nyob rau hauv cov nqe lus ntawm cov khoom siab tau, cov khoom siv roj tuaj yeem compressed los ntawm compressor, los yog cov khoom ua kua tuaj yeem raug nias los ntawm lub twj tso kua mis ua kua, thiab tom qab ntawd tso tawm tom qab vaporization thiab rov ua kom sov hauv lub tshav kub exchanger. Tam sim no, cov txheej txheem cryogenic cua sib cais yooj yim suav nrog cov txheej txheem sab nraud compression cua sib cais, sab hauv compression cua sib cais txheej txheem, oxygen tus kheej-pressurization huab cua sib cais txheej txheem, tag nrho cov kua cua sib cais txheej txheem, peb-ntauwd cua sib cais txheej txheem, LNG txias zog siv cua sib cais txheej txheem , siab nitrogen cua sib cais txheej txheem thiab huab cua sib cais txheej txheem nrog tsawg roj.
Cov txheej txheem no txhua tus muaj lawv tus yam ntxwv thiab qhov zoo, thiab tsim nyog rau cov xwm txheej sib txawv thiab kev xav tau. Lawv muab high-purity oxygen, nitrogen thiab lwm yam tseem ceeb gases rau ntau industries xws li steel, chemicals, thiab electronics, thiab tau zoo txhawb lub efficiency thiab refined txoj kev loj hlob ntawm industrial ntau lawm.
