Abstract: A liquid stream is transformed into a vapor and liquid medium, then plasma state is generated in the medium, which generates various high-energy particles causing a number of physical and/or chemical effects, then the vapor and liquid medium is condensed back into an output stream of liquid. Liquid feedstock (e.g. water) is nebulized using pressure drop and/or acoustic waves within a chamber, then an electric field exceeding the breakdown voltage threshold of the nebulized medium is applied to the medium, thus igniting plasma state. At the exit of the chamber, the nebulized medium is transformed back into liquid state. Liquid treatment with plasma state applications are thus enabled with high versatility and control in igniting and maintaining a plasma state at a cost-effective level of energy consumption.

Abstract: The invention provides a method and apparatus for creating plasma particles and applying the plasma particles to a liquid. Liquid feedstock (e.g., water and/or hydrocarbons mixed with biomass) is pumped through a pipeline; the single-phase stream is then transformed into a biphasic liquid-and-gas stream inside a chamber. The transformation is achieved by transitioning the stream from a high pressure zone to a lower-pressure zone. The pressure drop may occur when the stream further passes through a device for atomizing liquid. Inside the chamber, an electric field is generated with an intensity level that exceeds the threshold of breakdown voltage of the biphasic medium leading to a generation of a plasma state. Furthermore, the invention provides an energy-efficient highly adaptable and versatile method and apparatus for sanitizing water using plasma particles to inactivate biological agents contaminating water.
