Flue Gas Desulfurization System, Open Spray Design, Part 2

Learning objectives

  • Explain what happens to the scrubbing slurry
  • Discuss the practice of reusing the slurry and identify how the pH is maintained for good scrubbing action
  • Identify the function of the blowdown system
  • Describe the pond return system
  • Explain the operation of a lime system
  • Identify how the flyash is used
  • Explain the operation of the scrubber inverters

Course overview

Part one discussed how the flue gas travels through the open spray design scrubber. Flue Gas Desulfurization, Open Spray, Part 2 discusses the process surrounding waste slurry, including cleaning and reuse.

This online training course explains the process for cleaning SO2 out of flue gas. It also provides general knowledge of each system used in the process. This course includes:

  • Maintaining scrubber slurry
  • Blowdown system
  • Pond return system
  • Lime process
  • Flyash process
  • Scrubber inverters

This course is part of the Fundamental Aspects of Emission controls training series.
