Ammonia Recovery and Disposal?

Nice article here on absorption refrigeration, https://en.wikipedia.org/wiki/Absorption_refrigerator




1. Hydrogen enters the pipe with liquid ammonia

2. Ammonia and hydrogen enter the inner compartment of the refrigerator. An increase in volume causes a decrease in the partial pressure of the liquid ammonia. The ammonia evaporates, taking heat from the liquid ammonia (ΔH_Vap) and thus lowering its temperature. Heat flows from the hotter interior of the refrigerator to the colder liquid, promoting further evaporation.

3. Ammonia and hydrogen return from the inner compartment, ammonia returns to absorber and dissolves in water. Hydrogen is free to rise upwards.

4. Ammonia gas condensation (passive cooling).

5. Hot ammonia (gas).

6. Heat insulation and distillation of ammonia gas from water.

7. Heat source (electric).

8. Absorber vessel (water and ammonia solution).
