A method of improving the evaporation from surface bodies of water which comprises artificially inducing air flow over a body of water using air jets at an air flow rate of at least 10 m/second while the water partial pressure of air at the surface temperature of the body of water (Pbs) is greater than the water partial pressure of the ambient air at the surface temperature of the body of water (Pas). The rate of evaporation can be materially enhanced by the transfer of geothermal heat from the lower region of the body of water to the surface region by means of a heat exchanger or a heat pipe.

Waste pond volume management

A method for the reduction of corrosion in a treatment unit acid used for separating hydrogen sulfide from and acid gas stream using an alkaline absorption solution. Ions comprising the Sand/or HSions formed by the absorption of the hydrogen sulfide in the absorbent solution are subjected to in situ electrochemical oxidization to form polysulfide ions which form a protective coating on the surfaces of the unit.

Corrosion control in acid gas removal equipment by the situ generation of polysulfide ions

Methods and systems are provided for the in situ generation of polysulfide ions in a process stream including Sand/or HSions. Methods and systems are also provided to ameliorate corrosion in a process stream containing an acid gas or a scrubbing agent solvent, and abate mercury and cyanide in process streams containing a scrubbing agent solvent.
