Abstract
An apparatus and method for preparing and dispensing a liquid deicer. The apparatus and method allow deicer ingredients or precursors to be combined in an exothermic reaction to produce a heated deicer at the location where it will be used. In one implementation, potassium hydroxide and acetic acid are combined using the apparatus and method to make hot potassium acetate for use in numerous deicer applications, including deicing of airport runways.
Claims4
A method for forming a heated liquid deicer, the method comprising:
- providing a first vessel containing an acidic liquid;
- providing a second vessel containing an alkaline liquid;
- controllably transferring a portion of the acidic liquid and alkaline liquid into a mixing vessel configured for the exothermic reaction of the acidic liquid and the alkaline liquid, said mixing vessel having an input for acidic liquid, an input for alkaline liquid, and an output for the heated reaction product of the acidic liquid and alkaline liquid;
- and
- discharging the heated reaction product from the mixing vessel to an iced surface.
