| 20090026084 | Filter Wash for Chloralkali Process - Filter wash methods and apparatuses for chloralkali processes are provided. The filter wash uses in-process fluids from the chloralkali process to wash filters. The in-process fluids may be drawn from a point in the chloralkali process where the in-process fluids contain active chlorine values such as bleach. A filter may then be isolated from the chloralkali process and contacted with the in-process fluids containing active chlorine values to wash the filter. The in-process fluids containing active chlorine values may be operable to oxidize organic material clinging to the filter, thereby cleaning the filter. After washing, the in-process fluids containing active chlorine values may be returned to the chloralkali process to a point at or near where they were drawn from. The filters may be membrane filters. The filters may comprise expanded polytetrafluoroethylene. | 01-29-2009 |
| 20100051469 | Electrolysis Cell for the Conversion of Cuprous Chloride in Hydrochloric Acid to Cupric Chloride and Hydrogen Gas - The present invention provides an electrochemical cell for producing hydrogen gas and cupric chloride, comprising an anode compartment including an anode disposed in an anolyte, wherein the anolyte is cuprous chloride in hydrochloric acid, a cathode compartment including a cathode, wherein the cathode comprises an electrocatalyst, and a cation exchange membrane disposed between the anode compartment and the cathode compartment. | 03-04-2010 |
| 20100116680 | OXYGEN SEPARATION ASSEMBLY AND METHOD - An electrically driven oxygen separation assembly and method for applying an electrical potential in which the assembly has one or more tubular membrane elements. The potential is applied at two central spaced locations of a tubular membrane element and at least at opposite end locations thereof. As a result the electric current flow through the tubular membrane element is divided into two parts flowing between the two central spaced locations and the opposite end locations. Additionally, the present invention also provides an end seal to be used in connection with tubular membrane elements. | 05-13-2010 |
| 20110042228 | PEM WATER ELECTROLYSER MODULE - A PEM water electrolyser module comprising a plurality of structural plates each having a sidewall extending between opposite end faces with a half cell chamber opening, at least one oxygen degassing chamber opening, and at least one hydrogen gas collection manifold opening, extending through the structural plate between opposite end faces. The structural plates are arranged in face to face juxtaposition between opposite end plates. | 02-24-2011 |
| 20110315560 | PROCESS FOR THE PRODUCTION OF CHEMICALS - A process for producing one or more chemical compounds comprising the steps of providing a bioelectrochemical system having an anode and a cathode separated by a membrane, the anode and the cathode being electrically connected to each other, causing oxidation to occur at the anode and causing reduction to occur at the cathode to thereby produce reducing equivalents at the cathode, providing the reducing equivalents to a culture of microorganisms, and providing carbon dioxide to the culture of microorganisms, whereby the microorganisms produce the one or more chemical compounds, and recovering the one or chemical compounds. | 12-29-2011 |
| 20120132536 | AN ELECTROCHEMICAL PROCESS TO PREPARE CHEMICALS USING A CYANIDE SALT - The present invention relates to a process comprising the reaction of a cyanide with a hydrogen cyanide-reactive compound, characterized in that the cyanide is a cyanide salt and the process is an electrochemical process involving the transporting of a reaction mixture to which cyanide salt has been added through an electrochemical cell, in which process the cyanide salt reacts with the hydrogen cyanide-reactive compound while at least partly under the influence of an electric current the cyanide salt is acidified and the salt cation content is reduced. | 05-31-2012 |
| 20140251819 | METHODS FOR HYDROGEN GAS PRODUCTION - According to aspects described herein, methods and systems provided by the present invention for hydrogen gas production include a RED stack including one or more RED subunits, and use of a saline material including a heat regenerable salt. The salinity driven energy, provided by the one or more RED subunits, completely eliminates the need for an external power source to produce hydrogen gas. | 09-11-2014 |
