ABSTRACT:
A method for spray drying an aqueous slurry in a spray drying tower. Hot effluent gases containing steam are divided into two portions. One portion is heated and recycled to the spray drying tower as part of the heated gas stream which dries the slurry. The other portion is condensed and subjected to a contaminant-removal operation such as scrubbing or electrostatic precipitation, under controlled conditions.
