A METHOD AND A SYSTEM FOR RECOVERY OF ANHYDROUS SODIUM SULFATE FROM REJECT STREAM OF SULFATE REMOVAL SYSTEM

摘要

The present invention comprises teaches an innovative method and a system to recover anhydrous sodium sulphate from the SRS reject stream in the caustic chlorine industry by selective crystallization of sodium sulphate hydrate followed by vaporative/ non-evaporative/ combination dehydration of Sodium Sulphate Hydrate.
