Abstract: Disclosed in the present invention are methods and apparatuses for the electrochemical conversion of halide ion containing brines into halogen based disinfection solutions while the impact of scale formation on electrochemical system operations. This is accomplished by controllably modifying the brine with one or more of halide ions, a halogen stabilization compound, an acid component, or a buffering component. These chemical modifications of the brine allow for the production of stabilized 10 halogen solutions, which can then be used as disinfectants. The present invention is especially useful in the production of halogen-based biocides from flowback or produced waters resulting from oil and gas production, but can be applied to any halide ion containing water stream, including reject water from reverse osmosis filtration processes or ocean water, that contains ammonia.

Abstract: Methods and apparatuses for electrolysis that does not require the use of a transformer to operate. The apparatus comprises one or more electrolytic cells which comprise the number of intermediate electrodes sufficient to enable the cell or cells to operate at the rectified line voltage without any need for voltage regulation, or near the rectified line voltage with only some voltage regulation, such as less than 20% of the rectified line voltage. Such regulation is achieved by using a buck or boost converter rather than a transformer, and can be varied to accommodate fluctuations in the line voltage and/or conductivity of the electrolyte, or varied to produce different chemistries in the same apparatus.
