  • Publication number: 20180237312
    Abstract: An object of the disclosure is to provide a method of efficiently producing a highly-pure vanadium electrolytic solution from a combustion residue that is discharged from facilities such as refineries and power plants and contains uncombusted carbon. The method of producing a vanadium electrolytic solution for redox flow cell (RFB) includes a vanadium eluate generation step of obtaining a vanadium eluate in which vanadium is dissolved. The vanadium is contained in a combustion residue obtained after combustion of a fossil fuel. The method further includes a precipitation step of mixing a sulfide precipitant into the vanadium eluate to precipitate a solid substance of precipitate in a reduction state and a wet oxidation step including a process of adding dilute sulfuric acid to the solid substance separated from the solution to generate a vanadium sulfate solution.

  • Publication number: 20180063470
    Abstract: There is provided a monitoring camera system including at least one monitoring camera and a recorder connected to the monitoring camera. The monitoring camera captures an image of an area of a monitoring target, detects a motion in a captured video of the area, associates information relating to the motion with the captured video, and transmits the associated result to the recorder. The recorder associates the captured video of the area captured by the monitoring camera and the information relating to the motion with the monitoring camera, and records the associated result. The recorder reproduces the captured video of the area on a monitor recorded in the way that a reproduction speed of the captured video in a section in which the motion is not detected on the monitor is faster than a reproduction speed of the captured video in a section in which the motion is detected, based on the information relating to the motion.

  • Patent number: 5368762
    Abstract: Tri- and tetravalent vanadium solutions suitable for a redox battery are produced as follows. Vanadium pentaoxide or ammonium vanadium is reduced in the presence of a concentrated sulfuric acid and a reducer, thus producing a solution containing tetravalent vanadium. At least a portion of the trivalent vanadium solution is heated to 180.degree.-250.degree. C., thus producing a trivalent vanadium compound. If the trivalent compound produced is a solid, it is collected and solubilized in water and/or sulfuric acid. Then, unreacted sulfur is filtered out, thus obtaining a trivalent vanadium solution.
