Powdered limestone (CaCO3) containing 22,000 ppm NaOH is to be washed in a two-step continuous countercurrent washing system to remove most of the NaOH. Two cells and 190,000 L of water per 10MT/day of limestone feed are used. The slurry discharged and removed from the underflow contains 0.085 MT of water per MT CaCO3. Assuming complete mixing and washing, calculate the NaOH content of the washed and dried limestone in ppm.
