The overall objective of this project was to determine the cost and impacts of Hg control using sorbent injection into a Compact Hybrid Particulate Collector (COHPAC) at Alabama Power's Gaston Unit 3. This test is part of a program funded by the U.S. Department of Energy's National Energy Technology Laboratory (NETL) to obtain the necessary information to assess the costs of controlling Hg from...

Electrospray was employed upstream of an electrostatic precipitator (ESP) to enhance the collection efficiency of monodisperse nanometer-sized particles. The electrospray of deionized water produced water droplets with a size range from several tens to several hundreds μm. The visible combined effect of the ESP with the electrospray was found for the collection of particles larger than about 20...

the removal of fine particles less than 2.5 μm in diameter generated from industrial plantsrepresents a serious challenge in air pollution abatement. these particles can penetrate deeply into the lungs and are difficult to remove by cyclones, electrostatic precipitators, and other conventional separation devices. in this paper, the influence of acoustic waves on removing aerosol particles from ...

Pulsed energization of electrostatic precipitator (ESP) may represent one of the most promising solutions to comply with strict environmental regulation in case of high resistivity dust. Performs a parametric cost comparison between conventional and pulsed ESP with reference to four main industrial areas: electric power generation, cement manufacturing, iron and steel production, glass industry...

Due to the increase in human activities and application of nanotechnology, people's exposure nano submicron particles is increasing. Conventional particle separation technologies, such as electrostatic precipitators, cyclone, wet washing, filtration method, cannot work well. In addition, fiber diameter pore size traditional filter material too large, bulk density difficult control. Nanofiber me...

Clarke's classification of situational crime prevention techniques is designed to provide a conceptual analysis of situational strategies, and to offer practical guidance on their use in reducing criminal opportunities. It has developed in parallel with a long program of empirical research, conducted by many researchers, on the situational determinants and the prevention of a wide variety of cr...

Telecommunications providers expect products to perform reliably during operation in the field. Achieving the expected hardware reliability is due to an amalgamation of multiple factors. A significant contribution to reliable performance results from the incorporation of specific materials, which are very corrosion resistant and electrostatic discharge (ESD) safe during the design and manufactu...

This study reviews the air pollution control strategy at an advanced semiconductor fab focusing on its continuous improvements and future challenges. A wide range of pollutants is emitted from various sources classified as organic solvents, corrosive, toxic combustible gases. effective employs a two-stage treatment method to comply with national emission regulations. Eight different types local...

this article studied static deflection, natural frequency and nonlinear vibration of a clamped-clamped microbeam under discontinues electrostatic actuation. the electrostatic actuation was induced by applying ac-dc voltage between the microbeam and electrode plate. in contrast to previous works, it was assumed that length of the electrode plate was smaller than that of the microbeam. in additio...
