Measuring the Flow Rate of a Gas System Perhaps the most fundamental parameter to be measured in gas handling systems is the flow rate. Determining the best method for measuring flow rate can be difficult. For low-pressure, non-toxic gas streams the pilot-tube...

Wet Scrubbers vs Dry Scrubbers – Which is Better? Frequently, wet scrubbers fail to achieve expected performance because the incoming hot gas stream evaporates the scrubbing fluid thus producing a “spray-dried” aerosol. In general, the potential for this problem is...

wet ESP and the Corona Quenching effect Operators of wet electrostatic precipitators (wet ESPs) often notice that the secondary current and voltage readings tend to rise and fall with the particulate loading. This phenomenon is known as space charge corona...

wet ESP and the Limits of the Deutsch Equation Those involved in the design of electrostatic precipitators (wet or dry) are familiar with the Deutsch Equation and its variations: The Deutsch Equation Efficiency = 1 – EXP(-AW/Q) Where, A = collecting area W = migration...
