Cyclonic spray scrubbers are an air pollution control technology. They use the features of both the dry cyclone and the spray chamber to remove pollutants from gas streams. Generally, the inlet gas enters the chamber tangentially, swirls through the chamber in a corkscrew motion, and exits.
Air pollution control systems (5 C, 44 P) B. Bioremediation (2 C, 39 P) O. Oil spill remediation technologies (31 P) V. Vehicle emission controls (12 P) W.
This type of technology can be used for example as a wet scrubber for air pollution control. Countercurrent flow exposes the outlet gas with the lowest pollutant concentration to the freshest scrubbing liquid. Many nozzles are placed across the tower at different heights to spray all of the gas as it moves up through the tower.
In order to reduce costs of P2 techniques, many officials are turning to pollution elimination strategies, thereby eliminating any need for end-of-pipe solutions. A task force was created by the EPA in order to directly target reduction strategies. The P2 program task force has 5 main goals: create feasible P2 objectives and corresponding time ...
However, in dry injection or spray drying operations, the SO 2 is first reacted with the lime, and then the flue gas passes through a particulate control device. Another important design consideration associated with wet FGD systems is that the flue gas exiting the absorber is saturated with water and still contains some SO 2. These gases are ...
Design engineers and decision makers need to take into account technical and economical criteria of each alternative when choosing a suitable technology. [ 3 ] : 215 Often, the main criteria for selection are: desired effluent quality, expected construction and operating costs, availability of land, energy requirements and sustainability aspects.
