17 Venturi Scrubbers YEN
VEN.l POWER REQUIREMENTS FOR A VENTURI SCRUBBER Calculate the power requirement of a venturi scrubber treating 380,000 acfm of gas and operating at a pressure drop of 60 in. H20. The gas horsepower may be calculated from a A P Alternately, the following equation may be used PG 0.157 A gt ' 0.157 60 9.42 hp 1000 acfm 9.42 hp 1000 acfm 380,000 acfm 3580 hp To determine the brake horsepower, the gas horsepower must be divided by the fan efficiency. Assuming a fan efficiency of 60 , the operating...
Electrostatic Precipitators ESP
An electrostatic precipitator ESP is being used to clean fly ash from a gas. The precipitator contains 30 ducts, with plates 12 ft high and 12 ft long. The spacing between the plates is 8 in. The gas is evenly distributed through all of the ducts. The following information can be used Gas volumetric flowrate 40,000 acfm Particle drift velocity 0.40 ft s Use the Deutsch-Anderson equation to calculate the efficiency of the precipitator. Also, use the modified Deutsch equation with a range of...

20 Absorption ABS
Briefly describe the absorption process. Gas absorption, as applied to the control of air pollution, is concerned with the removal of one or more pollutants from a contaminated gas stream by treatment with a liquid. The necessary condition is the solubility of these pollutants in the absorbing liquid. The rate of transfer of the soluble constituents from the gas to the liquid phase is determined by diffusional processes occurring on each side of the gas-liquid interface. Consider, for example,...
q
Using the data provided in the problem statement, calculate the efficiency for the situation where the flow is equally distributed with the same inlet loading. Since ql 3000acfm for all modules, 2 3000 1 - 0.995 1 3000 1 - 0.99 9 If neither the flow nor concentration are uniformly distributed, the general equation for the efficiency in a compartmentalized baghouse is used. 2 3.8 2500 1 - 0.995 1 4.25 4000 1 - 0.99 36,000 It can be seen that poor flow distribution causes the efficiency to...
