Abstract
A method for reducing the residual amine content of dried solids by adding water to the dried solids to form a wetted solids mixture and drying the wetted solids mixture to yield a dried product with a final amine content less than the residual amine content of the dried solids. An alkaline composition is also disclosed which further reduces the final amine content of the dried product.
