AIR POLLUTION CONTROL ENGINEERING

Process design is the distinguishing feature which differentiates the chemical engineer from all other engineers. As the field of air-pollution control engineering has evolved over the past several decades, it is obvious that the air-pollution control[r]

Biofilters have also been used to control the emissions of propane and hexane from the filling of aerosol cans. These systems can actually be built into the ground, so the containing vessel becomes the surrounding earth. Buried distribution pipes introduce the contaminated gas beneath the b[r]

15.4 BIOFILTER COMPARED TO OTHER AVAILABLE CONTROL TECHNOLOGY
Other control technology for the control of VOCs and air toxics include incineration, carbon adsorption, condensation, and wet scrubbing. The advantage that biofilters have over all of these technologies is[r]

Reduction of ground-level concentrations from a point source can be accomplished by elevation of the point of emission above the ground level. The chimney has long been used to accomplish the task of getting the smoke from fires out of the house and above the inhabitants’ heads. Unfortunately meteor[r]

Source Testing
5.1 INTRODUCTION
Source testing is measuring the air pollutant concentration and/or quantity at a source or stack. The terminology implies using test methods to measure concentration on a one-time or snapshot basis, as opposed to continuously monitoring the source as disc[r]

Adsorption is used broadly in the chemical process industries. Early on, one of its most significant applications was the drying of wet air over beds of solid desic- cants for pneumatic control instruments. Original process applications range from solvent reclamation in dry cleaning to[r]

Three combustion processes that control vapor emissions by destroying collected vapors to prevent release to the environment are (a) thermal oxidation — flares, (b) thermal oxidation and incineration, and (c) catalytic oxidation. Each of these processes has unique advantages and disadvantages[r]

Fundamentals of Particulate Control
To understand particulate control, one first must understand some fundamental concepts and properties of particulate. Figure 19.1 shows common terms associated with particulate material as a function of particle diameter. Particles of concern t[r]

d = diameter in inches of the largest particle to be conveyed
The above equation has been developed for use with ambient air. While it considers the effect of density of the particle, it ignores the density of the conveying gas. Where the gas density is considerably different from sea level[r]

The first commercial electrostatic precipitator (ESP) was developed by Sir Oliver Lodge and his colleagues, Walker and Hutchings, for a lead smelter in North Wales in 1885. Unfortunately, this application was unsuccessful because of problems with the high-voltage power supply and the high resistivit[r]

Damage costs to material and crops, cleaning costs due to soiling, and so on, although not easy to determine, can be estimated as a function of pollutant levels (Rid- ker, 1967). However, there is the problem of translating into monetary value the effects on health resulting from air pollu[r]

and garbage. We can take care of recreation land by cleaning up, after ourselves and not causing more pollution. Carpooling and public transportation will help reduce air pollution. Recycling is a type of conservation. Recycling is reusing items over again or in a new way[r]
