AIR POLLUTION CONTROL DEVICES
ABSTRACT
The project covers various types of air pollution control devices. The application of existing and new technology resulted in the development of many air pollution control devices. Some important pollution control devices are covered in the project. They are as follows
• Cyclones
• Incinerators
• Catalytic reactors
• Baghouses
• Electrostatic Precipitators
• Adsorption
• Absorption equipment & wet scrubbers
The performance characteristics, limitations, advantages are also covered in this project, along with their digramatic presentation. Various graphs are also provided for reference.
INTRODUCTION
With the passage of the 1971 Clean Air Act, industries experienced a significantly increased need to reduce air pollution. The application of existing and new technology resulted in the development of many air pollution control devices. They included:
• Cyclones
• Incinerators
• Catalytic reactors
• Baghouses
• Electrostatic Precipitators
• Adsorption
• Absorption equipment & wet scrubbers
In the last two dozen intervening years, much of this equipment has reached the end of its useful life, the original process parameters have changed rendering this equipment less effective, and historical failure modes and equipment limitations have been identified.
The major controlling performance parameters are:
• Particle size, weight, shape
• Particle velocity
• Gas temperature / density
• Solubility and pH
• System pressure drop and mass transfer conditions
• Particle size distribution
• Gas viscosity
• Humidity level
• Chemical stoichiometry
• Residence time
The following is a short primer on these devices, some of the effects of their controlling parameters, and their limitations, advantages, and operating problems.
