Probably the most reliable method for designing ESPs is to construct and operate a pilot
plant. However, time limitations and the expense of construction may make this impossible;
a pilot plant can easily cost one million dollars or more. A pilot ESP project can be
constructed on an existing industrial process. In this case, a side stream of flue gas is sent
to the small pilot ESP. Flue gas sampling gives valuable information such as gas temperature,
moisture content, and dust resistivity. Relating these parameters to the measured collection
efficiency of the pilot project will help the design engineers plan for scale-up to a
full-sized ESP.
