Nitrogen yog ib qho roj uas muaj nyob hauv huab cua.Nws muaj ntau yam kev siv xws li kev ua zaub mov, kev kho cua sov, hlau txiav, glassmaking, tshuaj lom neeg kev lag luam, thiab ntau lwm yam txheej txheem cia siab rau nitrogen nyob rau hauv tej daim ntawv los yog muaj peev xwm.
Nitrogen, raws li cov roj inert, muaj ntau yam kev muaj peev xwm rau cov lag luam roj, roj thiab petrochemical.Siv lub hauv paus tseem ceeb hauv kev saib xyuas cov nroj tsuag, pib-up thiab kaw kev npaj, nitrogen purging thiab tom ntej nitrogen spill test tsim txoj hauv kev tseem ceeb rau qhov txiaj ntsig zoo ntawm txhua qhov haujlwm.Yog li ntawd, nitrogen tau dhau los ua qhov tseem ceeb heev rau kev siv onshore thiab offshore.
Nitrogen tuav qhov tseem ceeb tshaj plaws thaum peb tham txog kev nyab xeeb hauv kev lag luam Roj thiab roj.Cov roj no ua kom muaj kev nyab xeeb thaum lawv raug ntxuav thiab hauv lwm qhov xwm txheej uas yuav tsum tau muaj qhov cua tsis zoo.Nrog lub hauv paus chiv keeb ntawm cov nqi qis thiab txhim khu kev qha nitrogen ntau lawm, ntau cov roj thiab roj kev lag luam tau xaiv cov tshuab hluav taws xob nitrogen.Nws muaj ob peb lwm daim ntawv thov ib yam nkaus, nyeem hauv qab no lwm daim ntawv thov ntawm nitrogen hauv kev lag luam roj thiab roj.
1. Nitrogen Blanketing
Nitrogen pam vov, tseem hu ua tank padding thiab tank padding, yog ib tug txheej txheem uas yuav tsum tau siv cov nitrogen rau ib lub thawv ntim khoom uas muaj cov tshuaj thiab hydrocarbons uas volatile thiab reactive nrog oxygen.Thaum lub tank yog purged nrog nitrogen, cov khoom (uas feem ntau yog kua) nyob rau hauv lub tank tsis tuaj nrog oxygen.Planketing cia lub neej ntev ntawm cov khoom thiab qhov muaj peev xwm tawg tau raug txo qis.
2. Kev tshem tawm Nitrogen
Txhawm rau hloov cov huab cua tsis zoo lossis muaj kev phom sij nrog cov cua tsis zoo, Nitrogen purging yog siv los txwv cov ntsiab lus oxygen kom nws tsis hnov mob nrog lwm cov khoom tawg thiab cov hydrocarbons.Displacement thiab dilution yog ob txoj kev purging ntau tshaj plaws.Cov txheej txheem twg yog siv rau qhov system nyob ntawm nws qhov geometry.Kev tshem tawm tau zoo dua rau cov tshuab yooj yim thiab dilution yog siv rau cov txheej txheem nyuaj.
