Cov txheej txheem tshwj xeeb Flow ntawm Cua Separation Units

Cua Compression thiab Purification: Ua ntej, huab cua yog compressed rau ib tug tshwj xeeb siab los ntawm ib tug cua compressor thiab ces nkag mus rau hauv cov huab cua purification system. Nyob rau hauv cov txheej txheem no, impurities xws li plua plav, ya raws, thiab carbon dioxide raug tshem tawm los ntawm huab cua kom ntseeg tau tias kev ua haujlwm ruaj khov ntawm cov txheej txheem tom ntej thiab purity ntawm cov khoom kawg.

Cua Txias thiab Liquefaction: Cov huab cua ntshiab nkag mus rau hauv lub tshav kub exchanger, qhov twg nws undergoes tshav kub pauv nrog txias rov qab gases thiab txias mus rau ib tug kub mus txog nws liquefaction point. Tom qab ntawd, cov huab cua nkag mus rau hauv lub expander mus rau lub expansion tub yees, ntxiv txo nws cov kub thiab thaum kawg ua tiav liquefaction.

Rectification thiab Sib cais: Cov huab cua ua kua nkag mus rau hauv ib qho rectification kem, qhov twg nws dhau mus ntau lub voj voog ntawm ib nrab evaporation thiab ib nrab condensation. Vim muaj cov ntsiab lus sib txawv ntawm cov pa roj xws li oxygen, nitrogen, thiab argon, lawv qhov kev faib tawm hauv kab sib txawv. Oxygen concentrates nyob rau hauv qab ntawm kem, nitrogen concentrates nyob rau sab saum toj, thaum argon feem ntau concentrates nyob rau hauv nruab nrab seem. Los ntawm kev kho cov kev khiav hauj lwm tsis ntawm lub rectification kem, oxygen, nitrogen, thiab argon cov khoom ntawm txawv purity theem yuav tau.

Cov khoom tso tawm thiab rov qab: Cov khoom siv oxygen, nitrogen, thiab argon sib cais los ntawm cov kab kev kho kom zoo yog rov ua kom sov mus rau qhov kub thiab txias los ntawm cov khoom siv hluav taws xob thiab tom qab ntawd thauj mus rau qhov kawg - cov neeg siv los ntawm cov kav dej. Nyob rau tib lub sijhawm, ib feem ntawm cov pa roj sib cais tsis tiav (xws li oxygen- huab cua zoo lossis nitrogen-enriched cua) rov qab mus rau hauv lub kaw lus kom sib cais ntxiv, yog li txhim kho kev siv cov khoom siv raw.
