摘要： Disclosed are methods and systems for removing submicron particles from a gas stream, in particular from urea prilling off-gas, wherein a Venturi ejector is used. A method comprises contacting a gas stream containing submicron particles in a Venturi ejector with an injected high velocity scrubbing liquid to provide a pumping action, wherein the scrubbing liquid has an initial velocity of at least 2 m/s and wherein the ratio of scrubbing liquid and gas flow is between 0.0005 and 0.0015 (m3/h)/(m3/h). The disclosure also pertains to a prilling tower having a gas stream treatment system comprising a Venturi ejector at the top of the prilling tower, and to a method of modifying an existing prilling tower.

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： An air purification system comprises a chamber having an air inlet and an air outlet, a plurality of flexible wires hanging from a ceiling of the chamber, a spray mechanism configured to spray droplets in the chamber, and a sound wave generator configured to generate a standing sound wave in the chamber. During operation of the air purification system, the plurality of flexible wires are elastically deformed by the standing sound wave generated by the sound wave generator such that portions of the plurality of flexible wires converge at nodes of the sound wave, and also the droplets move to the nodes of the standing sound wave, while trapping particles in the air during the movement to the nodes. The droplets collide against and are adsorbed to the plurality of flexible wires at the nodes of the sound wave.

摘要： In the system of the instant invention, volatile organic compounds (VOCs) liberated in the course of solvent-based painting of a workpiece, are recovered. The atmosphere within a closed spray-booth is maintained at a fixed humidity such that vaporized water, supplied in the form of steam or nebulized water vapor, acts as a carrier for VOCs liberated in the course of spray painting or heat curing of a workpiece. The VOCs may be recovered continuously, including during the spray-painting or heat curing of the workpiece. The VOC laden, humidified air is circulated through a condenser such that VOCs dissolved in the water vapor condense and are directed to a recovery means. The water and solvent are separated, recovered and purified for re-use or placed in an appropriate container for disposal, thereby eliminating the usual practice of expelling VOC laden air into the atmosphere. The system is provided with a flame-free heat source to cure the painted workpiece and to guard against the danger of explosion.

摘要： A solids-laden gas is cleaned by introducing a condensing fluid in the gas to saturate the gas and allowing liquid to condense on the solids to form enlarged particles. Liquid separated from the gas with enlarged particles is then atomized in the gas to form agglomerates of liquid and enlarged particles, whereafter the formed agglomerates are separated from the gas. An apparatus for carrying out this process is also described, the apparatus being characterized by a first stage in which means are provided for enlarging solids in a solids-laden gas flow by contact with a condensing fluid, separation of liquid from the gas flow, and a second stage in which means are provided for introducing the separated liquid into the gas flow in a venturi-shaped gas passage member.

摘要： Apparatus and method steps for collecting sub-micron sized particles include a collection chamber and cryogenic cooling. The cooling is accomplished by coil tubing carrying nitrogen in liquid form, with the liquid nitrogen changing to the gas phase before exiting from the collection chamber in the tubing. Standard filters are used to filter out particles of diameter greater than or equal to 0.3 microns; however the present invention is used to trap particles of less than 0.3 micron in diameter. A blower draws air to said collection chamber through a filter which filters particles with diameters greater than or equal to 0.3 micron. The air is then cryogenically cooled so that moisture and sub-micron sized particles in the air condense into ice on the coil. The coil is then heated so that the ice melts, and the liquid is then drawn off and passed through a Buchner funnel where the liquid is passed through a Nuclepore membrane. A vacuum draws the liquid through the Nuclepore membrane, with the Nuclepore membrane trapping sub-micron sized particles therein. The Nuclepore membrane is then covered on its top and bottom surfaces with sheets of Mylar.RTM. and the assembly is then crushed into a pellet. This effectively traps the sub-micron sized particles for later analysis.

摘要： In order to obtain the requisite chimney temperature of cleaned gas discharged from a desulfurizing installation, and in order to avoid problems resulting at temperatures below the dew point of sulfuric acid in heat exchangers made of steel, the invention provides the following measures: the heat exchange between the crude gas stream and the cleaned gas stream is made in a first stage including conventional heat exchangers made of steel. An additional stage of heat exchangers between the crude and cleaned gas streams is constructed of corrosion-resistant and adhesion inhibiting plastic material and operating in a lower temperature range. Transfer conduits of corrosion-resistant material connect the lower temperature heat exchangers to forcibly transfer a heat carrying fluid.

摘要： Solid and liquid, especially high-boiling, impurities are removed from a gas stream containing solvent vapors in such a manner that the gas stream is washed with the condensate of one or more solvent vapors contained in the gas stream, preferably with the fraction which has the greatest affinity for the impurities to be removed. After a distillatory separation of the impurities, as befits the goals of the process, the solvent or solvent mixture used for the washing process is returned again into the process, preferably after it has been removed from the gas stream by condensation and/or adsorption. The gas stream can be returned into a vaporization chamber where it is again charged with solvent vapors.
