A separate collection and containment vessel intended to receive an emergency discharge of liquids, liquid reaction mass, or slurries originating from the bottom of a process vessel or reactor. The dump is usually automatically triggered by a process safety interlock, but may also be initiated manually. An uncontrolled exothermic or other runaway reaction can be controlled by discharging the process vessel contents to the dump tank. This may allow the process vessel to be returned to service in a shorter time.
