Sulfolane Cleaning


Degradation problems with Sulfolane?

Most common are:
  • Degradation by Oxygen- forms various acids of CO2 and SO2
  • Chloride contamination from CCR catalyst and Cooling water leaks
  • Trace olefins and other impurities

Case History

30% Sulfolane solution had high chlorides (1,700 ppm).
It also had 1,920 ppm Na (Sea water leakage).
MPR's HSSX® Process with Cations and Anion units reduced Chlorides to 13 ppm and sodium to less than 4 ppm. Color and solids were also removed.
