Air Pollution Control: Wet Scrubbers

COURSE NO: C05-021
PDH CREDIT: 5
Air Pollution Control: Wet Scrubbers
Course Highlights

This online engineering PDH course provides an introduction to the various types of wet scrubbers, as well as their design and cost considerations.

 

A wet scrubber is an air pollution control device that removes particulate matter (PM) and acid gases from waste gas streams of stationary point sources. The pollutants are removed primarily through the impaction, diffusion, interception and/or absorption of the pollutant onto droplets of liquid. The liquid containing the pollutant is then collected for disposal. There are numerous types of wet scrubbers that remove both acid gas and particulate matter.

 

This 5 PDH online course is intended for use by chemical or environmental engineers, design professionals, construction personnel and others involved in the planning, design and construction of air pollution control systems using wet scrubbers.

Learning Objectives

This PE continuing education course is intended to provide you with the following specific knowledge and skills:

  • Understanding the general function of a wet scrubber system
  • Knowing the meaning of PM10 and PM2.5 as measures of particulate matter size
  • Learning about the capture mechanisms for PM removal with wet scrubbers
  • Understanding the general characteristics of spray towers, cyclonic spray towers and tray towers
  • Understanding the general characteristics of dynamic scrubbers, venturi scrubbers, and orifice scrubbers
  • Understanding the general characteristics of other designs for wet scrubbers
  • Learning about the configuration and operation of venturi scrubbers
  • Understanding the general characteristics of liquid storage and delivery systems and liquid injection systems
  • Understanding the general characteristics of a venturi throat section
  • Understanding the general characteristics of a collection chamber and mist eliminator
  • Understanding the general characteristics of a waste liquid collection and disposal system
  • Learning about the type of auxiliary equipment used with wet scrubbers
  • Learning about the parameters affecting the overall performance of a wet scrubber
  • Learning about the general components of wet scrubber system design
  • Knowing the equations, graphs and tables available to assist in the system design process
  • Performing design calculations for estimating pressure drop, scrubber velocity and cross-sectional area
  • Performing calculations for the consumables, water usage and electrical power usage
  • Familiarizing with the general approaches to cost analysis for wet scrubber systems
