ABSTRACT:
The present invention provides methods for making gases generated in the treatment of hydrogen chloride wastes harmless by neutralization and dissolving, and an apparatus thereof, and a suction-type solution filter container to be used, and providing to shape useful materials or components, such as activated carbon with excellent adsorbability, from the post-treated residues of the wastes. Hydrogen chloride wastes are put in the sealed container 1 and heated at 400.degree. C. or less without oxygen or with air-blocked condition; the gases from the wastes, such as chlorine or hydrogen chloride, are sucked to extract from the container; the extracted gases are introduced into the suction-type solution filter container with liquid filtration agents to pass therethrough; chlorine is removed and reduced in volume from the wastes in the sealed container.
