Kev sib piv ntawm cov chaw nitrogen rau cov tshuab tsim nitrogen

Cov kua nitrogen yog cov khoom ntawm kev sib cais cua cryogenic Kev Tsim Khoom NitrogenNyob rau hauv cov xwm txheej txheem, 1m3 ntawm cov kua nitrogen tuaj yeem ua roj rau hauv 643m3 ntawm nitrogen, tab sis qhov siv tiag tiag thaum siv feem ntau yog li ntawm 95%, uas yog, 1m3 ntawm cov kua nitrogen tuaj yeem siv tau txog 610m3 ntawm nitrogen. Tam sim no, tus nqi lag luam nruab nrab ntawm cov kua nitrogen yog li ntawm 1,000 yuan / m3, thiab tus nqi ib chav ntawm nitrogen yog 1.67 yuan / m3. Thaum siv cov kua nitrogen, cov neeg siv yuav tsum tau nruab nrog cov thoob dej cia kua nitrogen, cov roj sib xws rau tus nqi ntws, thiab cov twj tso kua siab sib xws rau lub siab, uas yog cov peev txheej pib tsim nyog.

Kev tsim cov pa nitrogen los ntawm kev sib cais membrane kuj yog ib ceg tshiab ntawm kev tsim cov nitrogen uas tsis yog cryogenic. Nws yog ib txoj kev tsim cov nitrogen tshiab uas tau tsim sai sai hauv txawv teb chaws xyoo 1980. Nws siv cua ua cov khoom siv raw thiab siv cov pa oxygen thiab nitrogen sib txawv hauv cov fiber hollow hauv qab qee qhov siab kom cais cov pa oxygen thiab nitrogen los tsim cov nitrogen. Piv nrog rau ob txoj kev tsim cov nitrogen saum toj no, nws muaj cov yam ntxwv ntawm cov qauv khoom siv yooj yim dua, me dua, tsis muaj qhov hloov pauv, kev ua haujlwm yooj yim dua thiab kev saib xyuas, kev tsim roj sai dua (hauv 3 feeb), thiab kev nthuav dav peev xwm yooj yim dua.
