Wet scrubbers are the workhorses of industrial air pollution control. Whether you are removing particulate matter (PM), acid gases (HCl, SO₂, HF), or odors from a chemical plant, a properly designed scrubber ensures regulatory compliance and operational safety. However, commercial simulation software (like Aspen or ANSYS) is expensive and often opaque. For many engineering tasks—preliminary sizing, troubleshooting, or educational purposes—
