Ua ke nrog cov lus saum toj no, kev sib piv thiab kev tsom xam ntawm peb txoj kev tsim nitrogen yog raws li hauv qab no:
(1) Cov txheej txheem ntawmPSA siab viav vias adsorption nitrogen tiamthiabmembrane cais nitrogen tiamfeature kev ua haujlwm yooj yim, cov khoom siv tsawg dua, kev ua haujlwm yooj yim, thiab muaj peev xwm kaw tau txhua lub sijhawm (lossis tseem kaw rau lub sijhawm ntev). Piv txwv li,cryogenic sib cais nitrogen tiammuaj kev ua haujlwm nyuaj, ntau cov cuab yeej siv, thiab yuav tsum tau ua haujlwm raws li qhov ntsuas kub qis -kub. Ua ntej cov cuab yeej nkag mus rau hauv ib txwm ua haujlwm, yuav tsum muaj precooling pib- cov txheej txheem nce: lub sijhawm pib- nce (los ntawm kev ua kom lub turboexpander mus rau nitrogen purity lub rooj sib tham) feem ntau tsis pub tsawg tshaj 12 teev. Ua ntej cov khoom siv tau txais kev saib xyuas loj, qhov kub thiab txias - lub sijhawm nce thiab thawing (feem ntau 24 teev) yog qhov tsim nyog. Yog li ntawd, cryogenic sib cais nitrogen tiam tsis haum rau cov xwm txheej uas nquag pib-ups thiab shutdowns. Piv nrog rau PSA siab viav vias adsorption, membrane sib cais nitrogen tiam muaj ib qho yooj yim dua cov qauv (tsis muaj qhov hloov li qub), kev ua haujlwm yooj yim dua thiab kev saib xyuas, thiab lub sij hawm luv dua roj.
(2) Cryogenic sib cais nitrogen tiamtuaj yeem tsim tau ob qho tib si gaseous nitrogen thiab kua nitrogen, ua rau nws tsim nyog rau kev ua haujlwm uas yuav tsum tau ua kua nitrogen. Cov kua nitrogen tseem tuaj yeem khaws cia rau hauv lub tank ua kua nitrogen ua cov thaub qab: thaum cov nitrogen xav tau nce sai sai los yog cov khoom siv nitrogen tsim kho me me, cov kua nitrogen khaws cia tuaj yeem vaporized thiab pub rau hauv cov kav dej nitrogen kom ua tau raws li qhov xav tau nitrogen tas li ntawm cov txheej txheem. Piv txwv li,PSA siab viav vias adsorption nitrogen tiamthiabmembrane cais nitrogen tiamtuaj yeem tsim cov pa nitrogen nkaus xwb (tsis muaj kev ntsuas thaub qab), yog li ib chav tsev ntawm cov khoom siv no tsis tuaj yeem ua kom ntseeg tau ntev - lub sijhawm ua haujlwm tsis tu ncua ntawm cov txheej txheem.
(3) Thaum cov nitrogen purity (ntim feem) tsawg dua los yog sib npaug rau 97%, cov nitrogen rho tawm cov nqi ntawmPSA siab viav vias adsorptionthiabmembrane cais nitrogen tiam processes are roughly equivalent. When the nitrogen purity (volume fraction) >99%, nitrogen rho tawm tus nqi ntawmcryogenic sib cais nitrogen tiamyog qhov zoo, ua raws li PSA siab viav vias adsorption; lub extraction tus nqi ntawm membrane sib cais nitrogen tiam poob sharply. Lub caij no, los tsim cov nitrogen ntawm tib lub siab: lub qhov hluav taws xob cua siab ntawm cov cua compressor rau cryogenic sib cais nitrogen tiam yog piv rau cov PSA siab viav vias adsorption, thaum membrane sib cais nitrogen tiam yuav tsum muaj cua siab dua. Lub zog tseem ceeb ntawm tag nrho peb cov txheej txheem yog nyob rau hauv cov cua compressor; Yog li, thaum tsim high-purity nitrogen, membrane sib cais nitrogen tiam yuav tsum tau ib tug loj huab cua compressor (nrog ntau zog thiab tag nrho cov zog noj), ua raws li los ntawm PSA siab viav vias adsorption, thaum cryogenic sib cais nitrogen tiam muaj kuj qis zog noj.
(4) Cov txheej txheem nitrogen cais ntawmPSA siab viav vias adsorption nitrogen tiam(adsorption-desorption-adsorption) cuam tshuam nrog kev hloov pauv siab, ua rau lub siab tsis ruaj khov nitrogen. Nyob rau hauv sib piv, cov txheej txheem nitrogen cais ntawmcryogenic sib caisthiabmembrane cais nitrogen tiamyog nruam, yog li cov khoom nitrogen siab ruaj khov dua. Yog li ntawd,PSA nitrogen generatorsYuav tsum tau nruab nrog lub tank tsis muaj nitrogen ntawm qhov hluav taws xob nitrogen ntawm PSA adsorption ntauwd kom tsis txhob muaj nitrogen thiab tswj cov roj siab, yog li ua kom cov khoom ruaj khov nitrogen siab.
(5) Cryogenic sib cais nitrogen tiamCov cuab yeej siv ntau dua, kev ua haujlwm ntev dua, thaj chaw loj dua, thiab kev nqis peev ntau dua. Piv nrogPSA siab viav vias adsorption nitrogen tiam, membrane cais nitrogen tiamyuav tsum muaj huab cua ntau dua, siab dua piv, thiab lub compressor loj dua; cov khoom siv cua purification (filters, dryers, oil removers, etc.) kuj loj dua, ua rau muaj kev nqis peev ntau dua.
Tsis tas li ntawd, tus nqi ntawm cov membrane modules (cov ntsiab lus tseem ceeb ntawm cov membrane sib cais nitrogen tiam) yog siab dua li ntawm PSA adsorption yees. Yog li ntawd,PSA siab viav vias adsorption nitrogen tiammuaj nqis peev.
