Process of unslaked lime solidification reaction. (A) Reaction is performed in a warehouse with the windows removed. (B) For each reaction, 100–250 drums of liquid wastes and 7–12 tons of unslaked lime are loaded in a constant ratio with liquid wastes. (C) As the wastes and unslaked lime are mixed, thick noxious vapors rise during the heat reaction and escape through the open windows; the full reaction takes > 12 hr with emission of huge amounts of noxious gases and vapors. (D) Final stage of the process after 10 hr of thermochemical reaction.
