    摘要: A method and apparatus for removing BHP contaminants (alkali hydroxide and H2O2) from a recycled aqueous alkali chloride solution stream before the stream is fed to a chloralkali cell so that the contaminants do not impair the operation of a chloralkali cell. Unwanted alkali hydroxide within the recycled alkali chloride brine solution is reacted with chlorine gas and converted into an alkali chloride, which is useful in the operation of the chloralkali cell, and oxygen gas, which is outgassed from the system. Any H2O2 remaining in the recycled stream after elimination of the alkali hydroxide is reacted with chlorine to form HCl and oxygen gas. The HCl raises the pH of the brine solution, after which the pH may be adjusted by the addition of supplemental alkali hydroxide.

    摘要: Methods and apparatus are provided for the generation of hydrogen peroxide from an electrochemical (EC) cell arrangement. One embodiment of the apparatus comprises an EC cell having anode and cathode electrodes with a cation exchange membrane disposed between them to form anode and cathode compartments. An aqueous salt solution is supplied to the anode compartment and water and oxygen are supplied to the cathode compartment. An electric potential applied across the anode and cathode electrodes initiates an electrochemical process that results in the formation of an acid anolyte solution in the anode compartment and an alkaline catholyte solution in the cathode compartment. The anolyte solution and the catholyte solution are combined in a neutralizing chamber to form a neutral aqueous solution comprising hydrogen peroxide, salt, and water. The hydrogen peroxide is separated from the neutral aqueous solution by conventional means.

    摘要: A method of generating basic hydrogen peroxide (BHP) fuel for a chemical oxygen-iodine laser (COIL) using stored alkali chloride, typically potassium chloride, and water. The alkali chloride and water are mixed to form a saturated or nearly saturated aqueous salt solution for use as an anolyte feed to a chlor-alkali cell. The chlor-alkali cell generates alkali hydroxide, hydrogen, and chlorine. Water and oxygen are reacted to form peroxide which is combined with the alkali hydroxide from the chlor-alkali cell to form a dilute solution of BHP, a mixture of hydrogen peroxide and alkali hydroxide, which dissociates into O2H− and −OH. The BHP is concentrated and the molar ratio of hydrogen peroxide to alkali hydroxide is adjusted to 1:1 before the BHP is supplied to a COIL apparatus as fuel for the lasing process.

    摘要: A method and apparatus are present for increasing an intensity of light. Light is sent into an input of a housing in which a vacuum is substantially provided in the housing. The light sent into the input of the housing is converted into initial electrons. Movement of the initial electrons is caused to diverge from an axis through the housing to form diverged electrons. Additional electrons are generated to form an increased number of electrons in response to receiving at least a portion of the diverged electrons. The increased number of electrons is converted into output light that exits an output of the housing.

    摘要: An electrolytic cell for producing chlorine and basic hydrogen peroxide suitably includes an anode partition and a cathode partition separated by a membrane. The cathode partition is divided into a catholyte compartment and a gas plenum by a gas diffusion cathode. The anode partition electrolyzes alkali chloride received from the laser to produce free chlorine and alkali ions. The catholyte partition reduces oxygen received from the gas plenum through the cathode, and produces alkaline peroxide from the oxidized components combined with alkali ions received through the membrane from the anode partition. The cell is particularly useful in a fuel regeneration system (FRS) for a chemical oxygen iodine laser (COIL).
