Abstract
PURPOSE: To recover a halogen compound adsorbed on active carbon in a simple process with slight decomposition of the compound without corrosion problems of devices, by using low-temperature steam in vacuo rather than high-temperature one under normal pressure.
CONSTITUTION: A halogen compound, e.g. methylene chloride, chloroform, or trichloroethylene, adsorbed on active carbon is desorbed by treating with water at 10W100°C or an aqueous solution containing a stabilizer of a halogen compound, e.g. an ether or nitroparaffin, at 10W100°C in vacuo, and recovered. For example, an active carbon adsorption tank is charged with water or the solution at 10W100°C, and evacuated to distill away the compound as a vapor, which is recovered.
