Abstract: This disclosure teaches a composition and process which makes it possible to remove floating particulates or prevent the dissemination or particulates, by the misting of a solution that readily captures any particulate material in the air. More specifically, the present disclosure teaches the composition and use of aromatic compounds that are semi-volatile organic compounds (SVOCs) or slow evaporators in water-based carriers with surfactants as the misting/fogging agent for dust suppression. The particulate material is lowered to surfaces and removed by vacuuming, damp-wiping or using a dry cloth with a cationic charge (static cloth). This method can be achieved with neutral air pressure differentials in the work areas.

Abstract: 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.

Abstract: A scrubber removes matter (e.g., particulate, gaseous, or liquid) from a gas stream in order to recover the matter and/or to clean the gas. In particular aspects, the scrubber contains multiple venturis that may provide additional flexibility and increased efficiency. The invention also pertains to related methods.

Abstract: An apparatus for reducing air pollution includes a piping system, at least one compressor fan, a cooling system, and a tank having at least one first filter and at least one second filter separated by at least one intermediary member. The piping system is coupled to a cooling system adapted to saturate the exhaust with water. The exhaust and contaminated water flow downward into the tank containing at least one first filter and at least one second filter separated by at least one intermediary member where the exhaust and the contaminated water are filtered. The cleaned water is recirculated through the cooling system, and the exhaust is filtered a second time through the at least one second filter, the at least one intermediary member, and the at least one first filter prior to release into the atmosphere. A method for reducing air pollution from exhaust is also provided.
