Abstract: A method and apparatus for applying a foamed mixture of paints on a structural surface. A continuous stream of high velocity gas moves through a nozzle and is directed toward the structural surface, and two or more paints may be intermittently moved into the gas stream of the nozzle and aerated and mixed with each other and moved with the gas stream to form a foam that is applied to the structural surface. The components of the foamed mixture may include single component or plural component materials such as polyurethane foam, adhesive, and polyurea formulations, and may be moved through a volumetric metering device consisting of material heaters, a heated hose, and an applicator gun. The nitrogen gas stream fluidizes the mixture as it passes through and out of the nozzle and forms the mixture into a foam that is applied to the structural surface.

Abstract: Processes for recovering electrical power from a process unit waste heat steam generation system are described. A power-recovery turbine reduces the pressure of a stream of superheated steam to a pressure lower than that needed by the steam reboiler for use in other process units or equipment in the plant.

Abstract: A spray quantity adjustable foam/liquid dual-purpose distribution device includes a gas compressor, an isolation electromagnetic valve, a liquid accumulator, an electromagnetic valve, and a foam generation device that are connected to each other. The gas compressor supplies pressurized gas into the isolation electromagnetic valve and/or the liquid accumulator or the foam generation device. When the pressurized gas is supplied into the liquid accumulator, an internal pressure of the liquid accumulator is increased to force liquid contained in the liquid accumulator toward the electromagnetic valve, which, once activated, conduct the liquid to the foam generation device, so that the pressurized gas and the liquid are mixed in the foam generation device to generate a foamed liquid that is discharged out through an egress opening.

Abstract: A process mechanically breaks colloidal suspension bonds with the surrounding fluids through high energy impact with a stationary plate or a colliding fluid stream. The fluid with a colloidal suspension is pumped through one or more ?? to 3? nozzles to collide with either a stationary plate in an impact chamber at high velocity, or another similar or different fluid stream. The process breaks the bonds maintaining the colloidal suspension, disassociates these materials, and allows for gravity or chemical separation of the previously colloidal particles from the fluid. The process can separate colloidal particles from a liquid medium through pressurization followed by high energy impact and rapid release.

Abstract: A multiple action forced fluid evacuation system includes a reservoir for receiving a working fluid therein, and a shutoff valve provided in the reservoir. An outer rigid conduit and an inner flexible conduit are connected between the shutoff valve and a receiver. A processing module is provided for at least controlling pressurized gas between the outer conduit and the inner conduit, and is operatively connected to the outer conduit and the inner conduit. A nozzle has one end in fluid communication with a source of the working fluid, and an opposite end removably coupled to the receiver. The nozzle normally enables flow of the working fluid through the inner conduit to the reservoir when the nozzle is connected to the receiver until the working fluid in the reservoir activates the shutoff valve causing the nozzle to cease flow of the working fluid leaving a portion of the working fluid trapped in the receiver and the inner conduit.

Abstract: Various apparatus provide for spraying high velocity droplets of liquid into a low velocity gas stream. Finely atomized droplets may quickly transfer their momentum to the gas, resulting in deceleration of the spray and acceleration of the gas. A high velocity spray of atomized liquid may transfer a substantial fraction of its kinetic energy to the gas before contacting a surface, in some aspects, suspended particles in the gas phase may be removed by high velocity liquid droplets passing through the gas. Certain aspects provide for controlling a gas flow by controlling the relative amounts of upstream and downstream momenta transferred to the gas by one or more liquid sprays.

Abstract: A phase enhanced gas-liquid absorption method is disclosed. By adding an organic mixture or compound into a conventional gas-liquid system, the organic mixture forms a layer between the gas mixture and the liquid carrier. In this modified system, the absorption rate of the gas is significantly increased by the organic mixture, which plays a role of transporting the gas from the gas mixture to the liquid carrier.

Abstract: Foam for suppressing fires is formed by mixing together a constant stream of compressed air and water from a pump at a controlled rate with a quantity of a foaming agent from a foaming agent supply proportional to the rate of flow of water so as to be incorporated therein. An agitator mixes the water and the foaming agent into the stream of compressed air to generate the foam. The rate of flow of the water is controlled by a continuously variable valve member driven between five set positions by an electronically controlled motor including a fully open position, in which a maximum flow rate of the water is supplied to the mixer with the proportional quantity of a foaming agent, a fully closed position, in which the flow of water and the flow of a foaming agent from the foaming agent supply are halted, and at least three intermediate positions of different foam characteristics.

Abstract: Spherical particles having a size on the order of 0.1 to 100 microns in size are created by systems and devices of several types. The device includes a source of a stream of gas which is forced through a liquid held under pressure in a pressure chamber with an exit opening therein. The stream of gas surrounded by the liquid in the pressure chamber flows out of an exit orifice of the chamber into a liquid thereby creating a monodispersion of bubbles with substantially uniform diameter. The bubbles are small in size and produced with a relatively small amount of energy relative to comparable systems. Small particles of liquid may also be produced. Applications of the technology range from oxygenating sewage with monodispersions of bubbles to inhalation therapy with monodisperse aerosol dispersions of pharmaceutically active drugs.
