Recovery of Value-Added Chemicals from Hazardous Waste Pickle Liquor through Application of Full-Scale Fluidized Bed Reactor System

This paper represents the application of full-scale fluidized bed technology with recourse to recovery of value-added chemicals from the spent liquor generated from steel pickling processes in the steel manufacturing industry, achieving Zero Effluent Discharge (ZED). Optimization of the process variables of a full-scale fluidized bed reactor for the recovery of hydrochloric acid (HCl) and iron oxide (Fe2O3) are discussed.
