Tris (isodecyl) guanidine degradation in the MCU system

The current solvent blend consists of four components; an extractant, the modifier, a suppressor, and the diluent. Of the four components, only the suppressor – tris(isodecyl)guanidine (TiDG) has exhibited an appreciable depletion rate during facility operations.∇ Using data derived from MCU process samples, SRNL derived a method to predict the TiDG depletion based upon time and volume of feed processed. With the current data set, the following formula can estimate the TiDG concentrations after processing: At = [A0×exp(-0.000900×t)] – [5.39E-06×volume] where At is the TiDG concentration (mM) at time t (days), A0 is the TiDG concentration (mM) at time = 0, and volume is the amount of salt solution processed in gallons from time 0 to time t. The ability to use this formula as a predictive tool is limited due to the number of data points obtained for this scope of work. As such, this formula should not be used to precisely predict future TiDG concentrations.
