  • Patent number: 9834442
    Abstract: A reactor for reforming a liquid hydrocarbon fuel, and associated processes and systems, are described herein. In one example, a two stage process is disclosed in which a first reactor is coupled to a second stage reactor having a reaction volume greater than the first reactor. In the first reactor, the liquid hydrocarbon fuel is partially reformed and thereafter is inputted into the second stage reactor for complete partial oxidation. The reaction product is at last partially synthesis gas, a mixture of carbon monoxide, hydrogen, as well as other low hydrocarbons such as methane, ethylene, ethane, and acetylene. The low hydrocarbons can be reformed further in a solid oxide fuel cell. A portion of the gaseous, rotating contents of the second stage reactor may be input into the first reactor to help generate and sustain rotation within the first reactor.

    Abstract: Disclosed is a device and method for contacting a biological substrate. A non-thermal plasma device delivers a non-thermal plasma discharge using a dielectric conduit, an igniter electrode and a RF electrode. The dielectric conduit fluidicly communicates a gas therethrough and an igniter electrode ionizes at least a portion of the gas. The RF electrode, disposed circumferentially proximate to the exterior of the dielectric conduit, generates non-thermal plasma from the ionized gas. The non-thermal plasma is discharged from the dielectric conduit and contacts a biological substrate. The non-thermal plasma discharge may be suitable for tissue bonding and sterilization applications.

  • Publication number: 20160152494
    Abstract: A treatment system for treating water, such as produced water that is produced during hydraulic fracturing. The system employs a combination of a plasma spark discharge and an RF oscillating electric field. The plasma spark discharge and the RF oscillating electric field may be employed simultaneously or in an overlapping manner within a chamber to treat the water. The treatment system is able to kill microorganisms as well as reduce or eliminate fouling due to, for example, bicarbonates. In some embodiments, grids are employed to further enhance the heat produced by the RF oscillating electric field.

The pulsed plasma discharge is generated using a suitable electrode configuration to generate the plasma discharge in the fluid. Apparatus useful in the method may include a vessel, at least two electrodes for generating a plasma discharge in water, and a flow inlet and a flow outlet to allow water to be passed through the vessel. Also described is an in-line water treatment, where a pulsed plasma discharge is used in a pipe carrying moving water. Plasma based fluid treatment system may have many advantages in comparison to other treatment methods, such as very minimal maintenance, low operating power, and minimal pressure loss through the device.
