Abstract
The present invention is directed to vapor suppression of liquids through disposing a layer of surfactant onto the surfaces of liquids for surfactants having a density greater than the liquid and regardless of surface tension spreadability issues, and compositions comprising the surfactants in aerosolized form.
Claims22
1-32. (canceled)
A method for disposing a surfactant onto an evaporating surface within an enclosure to reduce evaporation from the evaporating surface, the method comprising:
- providing an aerosolized liquid surfactant composition having nano-sized droplets;
- depositing the aerosolized liquid surfactant composition onto the evaporating surface to form a layer thereon;
- and
- decreasing the evaporation rate from the evaporating surface.
36-54. (canceled)
A method for disposing a surfactant onto an evaporating surface within an enclosure to reduce evaporation from the evaporating surface, the method comprising:
- aerosolizing a liquid surfactant composition with an atomization nozzle;
- generating nano-sized droplets of a surfactant composition by flowing the aerosolized liquid surfactant composition through a Venturi tube comprising a first inlet in fluid communication with the atomization nozzle, a first outlet, and a first elongated throat portion comprising at least two rings of jets therebetween;
- and
- depositing the nano-sized droplets onto the evaporating surface to form a layer thereon.
