3. Assume standard temperature and pressure. Process exhaust gas with a volumetric flow rate of 100,000 cfm that contains 5 gr/ft of cement particulate matter is to be treated with an ESP. Regulatory requirements dictate that the outlet particulate matter concentration must be 0.02 gr/ft. Assume a plate to plate spacing of 10 inches and an applied voltage of 15,000 volts. The smallest particles in the gas stream are 2m in diameter, and all particles have a dielectric constant of 5.5. Estimate a. The particle drift velocity b. The required collection plate area to meet regulations c. Assume that plates with length and height of 30 feet are used. Estimate the number of plates required.
