Abstract
An alcohol-based solvent chiller includes an insulated vessel; a spiral-shaped heat exchanger designed specifically to chill alcohol-based solvents that become viscous at low temperatures within the insulated vessel; a cryogenic tank with pressure building capability that will force coolant through the heat exchanger at a specific pressure; and a cryogenic pump to circulate viscous cryogenic temperature liquids within the insulated vessel.
