This paper presents an evaluation of available technologies to recover hydrochloric acid from spent wire pickling solutions. Technologies reviewed include prohydrolysis, acid retardation, diffusion dialysis, and evaporative recovery. A case study, based on typical batch pickling waste, examines energy consumption, chemical mass balance, and end products. An economic review of the capital and operating expenses is also presented.
