VOLATILE LIQUID CATALYST HANDLING SYSTEM INCLUDING DISTRIBUTION CABINET Abstract of the Disclosure A system for delivering liquid catalyst to a core-making machine includes a single fireproof cabinet in which is located a catalyst storage tank. The storage tank receives catalyst from catalyst supply drums that are positioned one at a time in a pumping station located in the cabinet beside the tank and emptied into the tank by a barrel pump. A flash-off station is located in the cabinet beside the pumping station for receiving emptied drums and an exhaust hose, that is coupled to a scrubber system exhaust duct, is positionable within the drum to carry away vapors produced in the drum as residual catalyst flashes off. A catalyst supply pump is coupled for pumping liquid catalyst from the storage tank to a gassing unit of a core- making machine. Excess catalyst is returned from the gassing unit to the storage tank by way of a water-cooled heat exchanger which cools the returning catalyst and hence that remaining in the tank so as to keep the catalyst at a temperature low enough to prevent its vaporization and thus the vapor locking of the supply pump.
