Controlling PM and Acid Gas Mist in Industrial Plants with Wet ESPs

image-asset (3).jpeg

Topics presented in the webinar will include:

  • The role of wet ESPs as both key process components and emissions control devices

  • Wet ESP vs Dry ESP

  • Typical flue gas trains with wet ESPs

  • Types of Wet ESP technology (horizontal/vertical, plate designs, cleaning mechanisms)

  • Selecting from a wide range of Wet ESP materials of construction

  • Wet ESP water and effluent disposal options

Below are some of the questions discussed during the webinar:

  • Would you ever select a wet ESP for a dry flue gas?

  • Won't most metals condense under the conditions of the wet ESP and be captured by the wet ESP?

  • How does the footprint compare between the circular and plate type wet ESP designs?

  • What is AmecFW doing to advance wet ESP technology?Does ash resistivity matter in a wet ESP like it does in a dry ESP?

  • What is the major design parameter to consider other than ash content in an oil-fired boiler PM control, such as asphaltenes?

  • Any experience of retrofitting FGD scrubber flue gas condenser by installing wet ESP on top of the scrubber?

  • What is a typical plate spacing?

  • Are electrical TR sets single phase 60 Hz, mid-frequency, or high-frequency on two types discussed?

  • If the wet ESP doesn't capture HCl, where do the chlorides come from to use in the alloy design basis?

  • What would be AFW's recommendations for an oil-fired boiler with 4% sulfur with seawater FGD before stack in terms of PM control?

  • How does the wet ESP capture efficiency vary with small particle sizes? Is it similar at 0.01 micron, 0.1 micron, and 1 micron? We are dealing with a very fine acid mist (aerosol) - does the wet ESP struggle with this?
