摘要： In the manufacture of particulated metal oxides by the vapor phase oxidation of volatile metal halides, hot gaseous effluent streams are produced which, after separation of the desired particulated metal oxide therefrom, contain residual amounts of the particulated metal oxide as well as unreacted, volatile metal halide and halogen gas. The method of this invention provides for the recovery of these materials, individually, through a succession of contacting and separating steps utilizing a recycle stream of previously recovered, unreacted, liquid metal halide. Utilization of the recycle stream of metal halide provides for both evaporative cooling of the hot gaseous effluent stream to permit recovery of the residual particulated metal oxide therein and scrubbing of the resulting off-gas to recover the unreacted volatile metal halide therein as a liquid and provide a gas phase containing the by-product halogen gas. The recovered unreacted volatile metal halide liquid constitutes the recycle stream of liquid metal halide used in the process. The gas phase is subjected to a further scrubbing to separate and recover therefrom any remaining unreacted, volatile metal halide.

摘要： A system and process is disclosed for eliminating paint solvents released during paint spraying operations into the circulated air including a liquid spray solvent stripper over which the exhaust air is passed, and a heating and cooling arrangement for regenerating the solvent absorber liquid. A heat exchanger recovering heat from an incinerator vaporizes the solvent and the absorber is recovered by being passed over cooling coils in a condensing chamber. The exhaust air is treated with a water circulation system to remove paint solids, a proportion of the solvent vapors passing into solution with the treatment water. A solvent stripper is provided consisting of an arrangement for applying a vacuum to the water circulated from a paint solid removal unit, causing the solvent to be vaporized out of solution, with the vapors condensed by being passed over cooling coils in a condensing chamber. The air and water stripper condensing chambers are purged by a vacuum pump directing the uncondensed solvent vapors into the incinerator.

摘要： A droplet generator includes a chamber including an enclosed space filled with gas having vapor, a tube extending through the chamber, a gas flow channel inside the tube, and a heater in the chamber. The tube includes a sidewall having an outer surface exposed to the enclosed space of the chamber, and an inner surface. The tube contains liquid. The heater is operable to change a phase of the liquid contained in the tube to vapor such that the vapor is provided into the enclosed space. A pressure in the enclosed space is higher than a pressure in the gas flow channel such that the vapor in the enclosed space flows to the gas flow channel by passing through the tube.

摘要： Disclosed is a method for the removal of soluble particulate matter from a gas stream, such as urea dust from the off-gas of a finishing section of a urea production plant. The method comprises subjecting the off-gas to at least two quenching stages an aqueous quenching liquid. The quenching liquid used in a first, upstream quench stage, is allowed to have a higher concentration of dissolved particulate matter than the quenching liquid in the second, downstream quench stage. The quenched gas is led through a particle capture zone, typically comprising one or more of a wet scrubber, a Venturi scrubber, and a wet electrostatic precipitator.

摘要： Disclosed are methods, apparatuses, assemblies, devices and systems for removing pollutants from air within a space or an environment. Humidifiers introduce a pollutant trapping material into the air of the space or environment by evaporating the pollutant trapping material, wherein the pollutant trapping material adheres to pollutants in the air being purified. Dehumidifiers remove the pollutant trapping material, along with pollutants adhered thereto, from the air by dehumidifying it. The cooperation of the humidifier(s) and the dehumidifier(s) may be collaborated based on a combination of pollutant concentration level value(s) and relative humidity level value(s) measured in the air.
