Abstract: A method of waste treatment includes treating partially-dewatered matrix with a first electron-beam radiation dose. The treated partially-dewatered matrix is transferred to a digester where the treated partially-dewatered matrix is subjected to anaerobic digestion. Biogas is recovered from the treated partially-dewatered matrix during the anaerobic digestion. The treated partially-dewatered matrix is dried and subjected to a second electron-beam radiation dose.

Abstract: Disclosed are example efficient circuits that produce spark discharges for hydrocarbon conversion (or treatment of other mixtures) using a high-voltage rectified DC supply to discharge a capacitor (either internal or external) across a two-electrode gap, optimized to minimize waste energy by operating in a constant current, approximately-constant current, or constant power mode. The circuits may operate off of a standard electrical supply line (e.g. 120 VAC or 240 VAC, 60 Hz, single-phase or multi-phase). The disclosed approach is scalable to any number of discharge gaps while maintaining similar pulse characteristics and electrical efficiency.

Abstract: A high voltage discharge generating a plasma wave front is disposed within a headspace over an oil-containing liquid in order to create various chemical changes within the headspace, and ultimately within the liquid in order to inactivate various microbes, synthesize new chemicals, speed separation of a mixture, and aid in oil extraction. Such a discharge may be repeated at an optimum duration and duty-cycle to maximize the chemical effects of the non-equilibrium plasma at a substantially lower temperature than for an equilibrium plasma.

Abstract: Provided are systems and methods involving a plasma electro-coalescence reactor. The reactor includes a set of ports configured to receive an emulsified mixture into the reactor, receive a non-oxidative gas into the reactor, expel oil from the reactor, and expel water from the reactor. The reactor includes a set of electrodes including a first electrode in a headspace of the reactor, and a second electrode, the set of electrodes configured to receive a voltage at or in excess of a breakdown voltage of the non-oxidative gas.

Abstract: Hydrocarbon conversion and transportation methods and apparatuses are provided. An apparatus may apply electron beam irradiation to hydrocarbons (i.e., natural gas) to convert the hydrocarbons to liquid fuel. Lower-weight hydrocarbons may be converted into medium-weight organics through a gas to liquid process (GTL). The electrons may generate radicals that facilitate desired reactions. The hydrocarbons may be temperature and pressure controlled. For example, the hydrocarbons may be at lower temperatures (e.g., cryogenic or otherwise below ambient) and/or at higher pressures (e.g., greater than standard atmospheric pressures). Temperature suppression may reduce decomposition reactions. A high energy electron beam (e.g., 500 keV or higher, such as 10 MeV) could be used for the conversion process. The hydrocarbon may be liquefied. The liquid-like, higher density lower-weight hydrocarbons may lead to radical-neutral interactions. The high-energy electrons may penetrate the liquid hydrocarbon, treating more than just the surface of the liquid hydrocarbon.

Abstract: A breath capture and analysis system includes a breath inlet for capturing a user's breath. The breath is drawn into the system and retained for analysis. The system includes a membrane that allows volatile organic compounds contained in the breath to pass therethrough. The volatile organic compounds pass into a vacuum chamber that includes a residual gas analyzer that is configured to analyze the volatile organic compounds. The analyzed breath is then vacated from the system.
