Kev xaiv ntawm marine urea raw cov ntaub ntawv thiab tswj cov tshuaj tiv thaiv tej yam kev mob

Lub ntsiab raw khoom ntawm marine urea kua yog urea thiab dej. Urea yog cov organic compound nrog cov tshuaj formula CO (NH2) 2. Nws yog xim tsis muaj xim, pob tshab lossis xim daj me ntsis uas yooj yim soluble hauv dej thiab muaj cov nyhuv buffering. Dej yog cov kuab tshuaj ntawm urea kua, uas tuaj yeem sib cais ntawm urea thiab ua nws lub luag haujlwm hauv kev txo NOx.
Cov txheej txheem tsim khoom ntawm marine urea kua suav nrog peb cov tshuaj tiv thaiv, suav nrog hydrolysis ntawm urea, oxidation ntawm ammonia tsim los ntawm urea hydrolysis, thiab txo NOx los ntawm ammonia. Ntawm lawv, kev tswj cov tshuaj tiv thaiv kab mob yog ib kauj ruam tseem ceeb hauv kev tsim khoom. Cov tshuaj tiv thaiv kub, siab, concentration ntawm cov tshuaj tiv thaiv kua thiab pH tus nqi yuav tsum tau tswj nruj me ntsis kom ntseeg tau cov kev ua tau zoo ntawm cov tshuaj tiv thaiv thiab cov khoom zoo. Raws li ib txwm muaj, qhov ntsuas kub ntawm cov tshuaj tiv thaiv yog 130-160 degree, lub siab yog 4-6Mpa, thiab cov concentration ntawm cov tshuaj tiv thaiv kua yog 32.5%.
