Gas Flow Rate: Define this in both Actual Cubic Feet per Minute (ACFM) and Standard Cubic Feet per Minute (SCFM). Gas Temperature: Inlet and target outlet temperatures.

The primary goal of a scrubber is to maximize the contact time and surface area between the dirty gas and the scrubbing liquid. Whether you are designing a venturi scrubber for particulate matter or a packed tower for acid gas removal, the fundamental calculations remain the same.

This prevents flooding. We use the modified for packed beds.
