The Power and Recovery Subcommittee have proposed two new TIPs:

Sodium Sulfate (Sodium Thiosulfate) and Reduction Efficiency Measurement of Green Liquor in Chemical Recovery Processes -  this TIP will review available methods for measurement of sulfate and thiosulfate ions in green and white liquors for reduction efficiency calculation, addressing the latest measurement techniques and the potential economic returns of a good reduction efficiency in kraft mills

Recommended Practice for Refractory Selection and Installation in Recovery Boilers - this TIP will address practices to optimize refractory life including proper material selection, installation methods, curing time, and repair methods. 

If you are interested in being a part of the Working Group for these new TIPs, please contact standards@tappi.org by July 15, 2016.
