Turbulent jets and plumes - a Lagrangian approach

Wisdom of turbulent blending through plumes and jets, reminiscent of these encountered in smokestack emissions, volcanic eruptions, and sewage discharges, is necessary for controlling environmental effect and for assessing threat.

Dyes and Pigments

During this ebook the authors return to fundamentals to explain the structural modifications among dyes and pigments, their mechanisms of motion, homes and functions. They set the scene via explaining the explanations at the back of those modifications and exhibit how dyes are predominately natural compounds that dissolve or react with substrates, while pigments are (predominantly) finely floor inorganic elements which are insoluble and as a result have a special mode of coloring.

Visibility. The Seeing of Near and Distant Landscape Features

Visibility: The Seeing of close to and far-off panorama beneficial properties reports the technological know-how of visibility from tips on how to degree it quantitatively to its affects through one of many most desirable specialists within the box. rigorously designed pedagogy permits a variety of readers, from regulators to researchers to exploit this publication to additional their knowing of the sphere.

Example text

Scrubber waste products One side effect of scrubbing is that the process only moves the unwanted substance from the exhaust gases into a liquid solution, solid paste or powder form. This must be disposed of safely, if it can not be reused. For example, mercury removal results in a waste product that either needs further processing to extract the raw mercury, or must be buried in a special hazardous wastes landfill that prevents the mercury from seeping out into the environment. As an example of reuse, limestone-based scrubbers in coal fired power plants can produce a synthetic gypsum of sufficient quality that can be used to manufacture drywall and other industrial products.

The main problem is the buildup of solids on the baffles. Table 1 summarizes the operating characteristics of baffle spray scrubbers.

They use the features of both the dry cyclone and the spray chamber to remove pollutants from gas streams.

Maintenance problems The main advantage of spray towers over other scrubbers is their completely open design; they have no internal parts except for the spray nozzles. This feature eliminates many of the scale buildup and plugging problems associated with other scrubbers. The primary maintenance problems are spray-nozzle plugging or eroding, especially when using recycled scrubber liquid. To reduce these problems, a settling or filtration system is used to remove abrasive particles from the recycled scrubbing liquid before pumping it back into the nozzles.
