  • Publication number: 20140238869
    Abstract: An electrochemical cell for the continuous acidification of alkaline water sources and recovery of carbon dioxide with simultaneous continuous hydrogen gas production having a center compartment, an electrolyte-free anode compartment having a mesh anode in direct contact with an ion permeable membrane, an endblock in direct contact with the anode where the endblock provides a gas escape route behind the anode, an electrolyte-free cathode compartment having a mesh cathode in direct contact with an ion permeable membrane, and an endblock in direct contact with the cathode where the endblock provides a gas escape route behind the cathode. Current applied to the electrochemical cell for generating hydrogen gas also lowers the pH of the alkaline water to produce carbon dioxide with no additional current or power. Also disclosed is the related method for continuously acidifying alkaline water sources and recovering carbon dioxide with continuous hydrogen gas production.

  • Patent number: 8808528
    Abstract: Electrolyte supply tanks and bubbler tanks for oxyhydrogen gas generation systems are provided which eliminate the introduction of electrolyte and water into the induction systems of internal combustion engines. Both types of tanks are equipped with porous polyethylene gas diffusers which break up incoming gas into microscopic bubbles, thereby facilitating the absorption of electrolyte mist and droplets returning to the electrolyte supply tank and minimizing splashing of incoming gas in bubbler tanks. Air diffusers having an average pore diameter of about 70 ?m are installed near the bottom of the electrolyte supply tanks, while air diffusers having an average pore diameter of about 35 ?m are installed near the bottom of the bubbler tanks.

  • Patent number: 8747647
    Abstract: In a process for chlorine-alkali electrolysis, use is made of an oxygen depletion cathode. The process is run with a high excess of oxygen. The oxygen needed for this is provided for a device of the gas separation, for example a VPSA plant or an air fractionation plant. The large quantities of oxygen produced lead to considerable costs of the process. According to the invention, the oxygen-rich atmosphere remaining after passing through the process is fed back into the device for gas separation as input gas. The device the gas separation is therefore operated with an oxygen-rich input gas and therefore produces a larger quantity of oxygen-rich gas, which in turn is fed to the oxygen depletion cathode. As a result of the circulation of the gas, the economy of the overall process is increased considerably.

  • Patent number: 8702915
    Abstract: Small, autonomous, low cost electrochemical gas generators containing an electrochemical cell assembly, a commercially available battery and a current controlling mechanism. Current control, which defines the gas generation rate, is achieved either electronically by means of a resistor or through mass transfer control by means of a gas permeable film of known permeability. In either case, the gas generation rates are generally from 0.1 to 10 cc/day. The gas source must contain an electrochemically active gas such as oxygen or hydrogen. Air is the preferred source for oxygen. These miniature gas generators, generally are less than 1.5 cm in diameter and length, require novel, compact, electrochemical cell assemblies. Various cell assemblies, generally 1 cm in diameter and less than 0.5 mm thick, are described. These miniature gas generators are used for the controlled release of fluids such as pheromones, fragrances, insect repellents, and the like.
