Black Liquor - Evaporation Process Control


Black Liquor Samples- Samples are evaporator feed liquor as well as liquor after first two evaporators.
  • Samples were run as received. Sample bottles were shaken and pipetted into a 5 mm id NMR tubes.
  • NMR sample tubes were placed into a 60 MHz process NMR system and spectra collected.
  • Spectra resolve lignin/cellulosic functionality of the black liquor from the water.
  • Spectra show functionality changes as a function of concentration in the samples.
