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
An apparatus for forming a heated liquid deicer, the apparatus comprising:
- a first vessel configured and arranged for retaining and dispensing an acidic liquid, said first vessel containing an acidic liquid comprising acetic acid;
- a second vessel configured and arranged for holding and dispensing an alkaline liquid, said second vessel containing an alkaline liquid comprising potassium hydroxide;
- a mixing vessel configured and arranged for the mixing and exothermic reacting of the acidic liquid and the alkaline liquid, said mixing vessel having an input for the acidic liquid comprising acetic acid, an input for the alkaline liquid comprising potassium hydroxide, and an output for the heated reaction product of the acidic liquid and alkaline liquid, said reaction product comprising a liquid deicer containing potassium acetate;
- and
- a liquid transfer mechanism in communication with the first and second vessels, said liquid transfer mechanism configured for the controlled transfer of the acidic liquid and the alkaline liquid into the mixing vessel.
An apparatus for forming a heated liquid deicer, the apparatus comprising:
- a first vessel configured and arranged for retaining and dispensing an acidic liquid;
- a second vessel configured and arranged for holding and dispensing an alkaline liquid;
- a means for mixing the acidic liquid and the alkaline liquid, the means having an input for acidic liquid, an input for alkaline liquid, and an output for the heated reaction 5 product of the acidic liquid and alkaline liquid;
- and
- a liquid transfer mechanism in communication with the first and second vessels, said liquid transfer mechanism configured for the controlled transfer of the acidic liquid and the alkaline liquid into the means for mixing.
