Abstract
A pickling process for descaling metal includes a two-stage filtering process to remove pickling liquor fog, mist, and/or vapors from a gas collected during the descaling process. The process includes a two-stage filtering arrangement that includes a first stage filter, which is arranged to remove a liquid phase of the pickling liquor from the gas, and a second stage filter, which is arranged to remove a gaseous phase of the pickling liquor the said gas. The recovered pickling liquor can advantageously be recycled for reuse because it is recovered in a relatively higher concentration that has heretofore been possible.
