High performance flow battery

High performance flow batteries, based on alkaline zinc / ferro-ferricyanide rechargeable (“ZnFe”) and similar flow batteries, may include one or more of the following improvements. First, the battery design has a cell stack comprising a low resistance positive electrode in at least one positive half cell and a low resistance negative electrode in at least one negative half cell, where the positive electrode and negative electrode resistances are selected for uniform high current density across a region of the cell stack. Second, a flow of electrolyte, such as zinc species in the ZnFe battery, with a high level of mixing through at least one negative half cell in a Zn deposition region proximate a deposition surface where the electrolyte close to the deposition surface has sufficiently high zinc concentration for deposition rates on the deposition surface that sustain the uniform high current density. The mixing in the flow may be induced by structures such as: conductive and non-conductive meshes; screens; ribbons; foam structures; arrays of cones, cylinders, or pyramids; and other arrangements of wires or tubes used solely or in combination with a planar electrode surface. Third, the zinc electrolyte has a high concentration and in some embodiments has a concentration greater than the equilibrium saturation concentration—the zinc electrolyte is super-saturated with Zn ions.

Submerged gas evaporators and reactors

A submerged gas processor in the form of an evaporator or a submerged gas reactor includes a vessel, a gas delivery tube partially disposed within the vessel to deliver a gas into the vessel and a process fluid inlet that provides a process fluid to the vessel at a rate sufficient to maintain a controlled constant level of fluid within the vessel. A weir is disposed within the vessel adjacent the gas delivery tube to form a first fluid circulation path between a first weir end and a wall of the vessel and a second fluid circulation path between a second weir end and an upper end of the vessel. During operation, gas introduced through the tube mixes with the process fluid and the combined gas and fluid flow at a high rate with a high degree of turbulence along the first and second circulation paths defined around the weir, thereby promoting vigorous mixing and intimate contact between the gas and the process fluid. This turbulent flow develops a significant amount of interfacial surface area between the gas and the process fluid resulting in a reduction of the required residence time of the gas within the process fluid to; achieve thermal equilibrium and / or to drive chemical reactions to completion, all of which leads to a more efficient and complete evaporation, chemical reaction, or combined evaporation and chemical reaction process.

Method and dispenser for mixing and discharging media

The object of the invention is to provide a method and a dispenser in which, compared with known dispensers, the fluid path design is simplified. The dispenser has a medium reservoir (19) containing a medium to be discharge during one discharge stroke of the dispenser (11). For this purpose a feed fluid flows through the medium reservoir and discharges the medium through a reservoir discharge opening. For producing a discharge stroke, the dispenser has an actuator (25), whose actuation at least indirectly leads to an impact spike (29) penetrating from the outside into the medium reservoir (19), so as to produce a connection between a pump (40) for a feed fluid and the medium reservoir. As a result of the pressure of the feed fluid flowing into the medium reservoir, at a point in the medium reservoir (19) differing from the entry point of the impact spike (29), an opening is formed.
