Abstract: 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.

Abstract: Methods for the prevention or mitigation of fouling in amine-treating systems comprising providing circulating aqueous amine solution and a hydrocarbon stream comprising at least one acid gas; and interacting the circulating aqueous amine solution with the hydrocarbon stream comprising the at least one acid gas to remove the acid gas from the hydrocarbon stream and entrain the acid gas into the aqueous amine solution. The circulating aqueous amine solution comprises entrained acid gas comprises foulant precursors; and polysulfide ions are introduced to react with the foulant precursors to decrease the rate of fouling within the circulating aqueous amine solution.
