Abstract

A process for recovering a hydrogen halide includes the steps of: contacting the industrial byproduct with sulfuric acid to form a slurry including a sulfate and a hydrogen halide; heating the slurry to drive off a gas phase including the hydrogen halide; condensing water and the hydrogen halide in the gas phase to form a hydrohalic acid; drying the slurry to form solids including the sulfate; melting the solids in a furnace to form a molten material; capturing gases including sulfur dioxide from the furnace; passing the gases over a catalyst to convert at least a portion of the sulfur dioxide in the gases to sulfur trioxide; condensing water and the sulfur trioxide in the gases to form sulfuric acid; and quenching the molten material to form a glass.
