An apparatus and method for adding an alkali metal promoter into steam and contacting the solution with a dehydrogenation catalyst during a dehydrogenation reaction is disclosed. The apparatus has a first conduit capable of transporting an alkali metal salt solution and a second conduit in fluid communication with the first conduit, the second conduit capable of transporting steam so that the alkali metal salt is dissipated into the steam prior to entry into a dehydrogenation reaction zone.

An apparatus for moving proppant from a container has a frame with a surface for suitable for receiving a container thereon, a hopper affixed to the frame, and a conveyor having a surface positioned below the hopper. The hopper has an opening at or adjacent to a lower end thereof. The hopper is suitable for receiving proppant from the container. The surface of the conveyor is suitable for receiving the proppant a discharged through the opening of the hopper. A receptacle is translatably positioned at the surface of the frame. A metering gate is translatably positioned adjacent to the opening of the hopper.

A system for limiting the flow from a dispensing valve when a dispensing cartridge is replaced with the system including a dispenser cartridge with a cam and a water socket with a flow limiter therein that is activeable in response to the position of the dispenser cartridge in the dispensing valve and operable in response to an upstream fluid pressure in the dispensing valve.

A proppant discharge system includes a container having an outlet formed at a bottom thereof, a gate affixed at the outlet and positioned on the floor of the container so as to be movable between a first position covering the outlet to a second position opening the outlet, a support structure having the container positioned on the top surface thereof. The support structure has at least one actuator affixed thereto. The actuator is positioned so as to move the gate between the first position and the second position. The container has a cage affixed on the floor thereof in a position over the outlet. The gate is positioned within the cage and is movable by the actuator so as to open the gate so as to allow proppant to be discharged therefrom.

A plant chemical and water mixing and dispensing apparatus (PCWMDA) comprising three major elements: a mixing chamber, a support member, and a pipe. All three elements are preferably integrally attached together and can made of various material including plastic, fiberglass or a composite to use the PCWMDA a person will place a second quantity of a plant chemical such as fertilizer, herbicide or bug killer into the mixing chamber. A water source provides water that is directed into a first end inlet on the pipe. The water flows upward through a first conduit into the mixing chamber. The water and chemical mix, and the mixture flows out of the mixing chamber via second conduit and back into the pipe. The water and chemical mixture then exits the pipe through a second end outlet, and is directed onto a desired area of plant-life.

A vessel for conveying a precursor-containing fluid stream from a precursor material contained within the vessel, the vessel comprising: an interior volume defined by a top, one or more sidewalls, and a base; and at least one fluid outlet for vaporized precursor, and at least one particle barrier that defines at least one particle restricted space within the interior volume, wherein said particle barrier comprises at least one 3-dimensional filter. A method for using the apparatus is also disclosed.

An airflow treatment device configured to be installed inline in the ductwork of an air handling system (e.g., HVAC system) in a manner that is substantially free of obstructing the airflow through the ductwork or requiring any supplemental power to treat the airflow passing by the treatment device. The disclosed airflow treatment device can also be maintained substantially free of any interruptions, disassembly or downtime to the air handling system after initial inline installation of the disclosed device. In one arrangement, the airflow treatment device is capable of accepting a threaded odor neutralizer container at its base. Ductwork need only be disassembled once to attach the disclosed device inline in the airflow path of the ductwork. When the odor neutralizing agent needs replenished, the container can be detached from the device, replenished, and reattached to the device free of disruption to the air flow of the air handling system.
