Abstract:
A solid oxide fuel cell comprising an electrolyte, an anode and a cathode. In this fuel cell at least one electrode has been modified with a promoter using gas phase infiltration.
Abstract:
The present embodiment describes a method of forming different layers in a solid oxide fuel cell. The method begins by preparing slurries which are then delivered to a spray nozzle. The slurries are then atomized and sprayed subsequently onto a support to produce a layer which is then dried. In this embodiment different layers can comprise an anode, an electrode and a cathode. Also the support can be a metal or a metal oxide which is later removed.
Abstract:
A process of producing degassed liquid sulfur using process gas containing H2S to agitate the liquid sulfur being degassed while in contact with a degassing catalyst. Process gas is less costly and less complicated and quickly accomplishes substantial degassing rendering the liquid sulfur much safer in storage and transportation.
Abstract:
Methods and apparatus relate to treatment of fluids to remove mercury contaminants in the fluid. Contact of the fluid with an amine that has absorbed a sulfur compound causes the mercury contaminants to be absorbed by the amine. Phase separation then removes from the fluid the amine loaded with the mercury contaminants such that a treated product remains.
Abstract:
A support impregnated with selenium and capable of effectively removing a heavy metal from a process stream that is at an ambient temperature or is at an elevated temperature.
Abstract:
The present disclosure relates generally to novel biomass pyrolysis processes and systems that decrease entrainment of char and other contaminants with the produced pyrolysis vapors.
Abstract:
An injection system may include a first hollow pipe through which a first fluid flows and a second hollow pipe through which a second fluid flows, the first fluid for mixing into the second fluid. The second hollow pipe may reside through a wall of the first hollow pipe and have an opening near its end that is near a centerline of the first hollow pipe. A longitudinal baffle may reside within the second hollow pipe and together with the second hollow pipe, define a first and second baffle flow path within the second hollow pipe for the second fluid. A transverse baffle may be attached to the longitudinal baffle to protrude into the opening of the second hollow pipe. The transverse baffle divides the opening into a first baffle flow outlet and a second baffle flow outlet, for the first baffle flow path and the second baffle flow path.
Abstract:
A quenching process for quenching a flowing first fluid with a flowing second fluid may involve a first hollow pipe for containing the flowing first fluid and a second hollow pipe for containing the flowing second fluid; dividing the flowing second fluid into a first baffle flow along a first side of a longitudinal baffle and a second baffle flow along a second side of the longitudinal baffle within the second hollow pipe; providing a transverse baffle protruding from the longitudinal baffle for directing the first baffle flow from a first baffle flow outlet and the second baffle flow from a second baffle flow outlet in the second hollow pipe and into the flowing first fluid in the first hollow pipe; and configuring an area of the first baffle flow outlet area to be greater than or equal to an area of the second baffle flow outlet area.
Abstract:
An oil in water analyzer for measuring the concentration of hydrocarbons in an effluent stream. The oil in water analyzer has a valve system for acquiring a sample from an effluent stream. An extraction device is used for mixing a known volume of a solvent and the sample to produce a hydrocarbon/solvent mixture. A second valve is used for transporting the hydrocarbon/solvent mixture to a spectroscopic cell. It is at the spectroscopic cell where the concentration of hydrocarbons in the hydrocarbon/solvent mixture is evaluated.
