The agitator assembly is positionable within the vessel and comprises a rotatable shaft and a first and second impeller coupled to the shaft. The first axial impeller is locatable within the first mixing zone and is configured to pump the liquid in a downward direction along a vertical axis of rotation. The second impeller is locatable within the second fluxing zone and is configured to pump the liquid in an upward direction along the vertical axis of rotation.

The invention generally relates to systems and methods for increasing reaction yield. In certain embodiments, the invention provides systems for increasing a yield of a chemical reaction that include a pneumatic sprayer configured to generate a liquid spray discharge from a solvent. The solvent includes a plurality of molecules, a portion of which react with each other within the liquid spray discharge to form a reaction product. The system also includes a collector positioned to receive the liquid spray discharge including the unreacted molecules and the reaction product. The system also includes a recirculation loop connected from the collector to the pneumatic sprayer in order to allow the unreacted molecules and the reaction product to be recycled through the pneumatic sprayer, thereby allowing a plurality of the unreacted molecules to react with each other as the unreacted molecules cycle again through the system.

An in-liquid plasma generation device includes a housing which holds a liquid in an internal space, a gas supply tube which includes an opening in the internal space and discharges a gas into the liquid through the opening, a first electrode which has projecting part projecting into the internal space via the opening from inside of the gas supply tube, the projecting part including a conductor covered by a dielectric, a second electrode which surrounds the projecting part of the first electrode and includes a conductor isolated from the liquid by a dielectric, and a voltage applier which applies a voltage to between the first electrode and the second electrode. A space between the projecting part and the second electrode is a flow passage in which the gas discharged from the opening flows.
