  • Patent number: 10047300
    Abstract: A novel process for metal content reduction of hydrocarbon oil is disclosed, which is primarily aimed at reduction of vanadium and nickel. The process uses electricity to accelerate the demetallation process, but only the flow of electrons of the electric current is used to expedite the reaction, instead of the electrolysis effect of the electric current. The process is carried out by adding inter-phase surface active reagent and phase transfer catalyst at a relatively low temperature range of 80 to 200° C. and achieves metal content reduction for vanadium and nickel. Aqueous phase alcoholic derivatives of amine solution is treated with hydrogen sulfide, carbon dioxide, etc. by additive reaction to render it more suitable for carrying more electric current and make them more active for metal reduction.

  • Publication number: 20140106007
    Abstract: The methods, systems, and apparatus disclosed herein employ natural, common salts, that are electrochemically activated (ECA) in an aqueous solution to result in an ECA product solution that is safe and non-toxic. Various implementations include a portable table top design having a portable receptacle that includes electrodes. The receptacle fits on a base which provides power for the electrochemical activation. Continuous flow designs receive input water, mix the water with reactants then pass the solution between electrodes to electrochemically activate the solution. Using a metal halide salt, such as NaCl with citric acid may produce a sanitizer or disinfectant. Using a metal carbonate salt, such as K2CO3, as the reactant may result in a cleaning or degreasing solution. Another implementation is that of an immersion wand that can be placed in a reservoir to produce the ECA product solution.

  • Patent number: 8636878
    Abstract: This is a device and process to generate alternating current without an external source for cell-houses in electro-winning or electro-refining of copper or other products in which the electric source consists of a conventional rectifier-transformer group that supplies continuous electrical current to the cell-house, which is connected in parallel to a device characterized by having the capacity to extract an electrical current from the cell-house for a period of time and then return it in another period of time, whether periodically or semi-periodically and without changing the average value of the electrical current, supplied to the cell-house by the rectifier-transformer. This results in an electrical current in the cell-house that is the superimposition of a continuous and alternating current. This process is designed to overcome the barrier of electric potential produced by the presence of the pure continuous electric field in cell-houses through the electric agitation of an ion-rich electrolyte.

  • Patent number: 8580414
    Abstract: Contemplated electrochemical devices and methods include an electrolyte flow path in which substantially all of the electrolyte has laminar flow. A segmented electrode contacts the electrolyte, and each of the segments in the segmented electrode is preferably coupled to a control device to provide control over the flow of current to and/or from the electrolyte. Thus, it should be appreciated that the redox state of the electrolyte can be changed in a single-pass through the flow path, which effectively eliminates problems associated with mass transport phenomena and reduced current efficiency.
