Several papers and calculation tools focus on the design of venturi scrubbers, often providing the fundamental equations for pressure drop and particle collection efficiency that are typical of Excel-based design templates.

To facilitate the design calculation process, XLS (Excel) can be used to create a spreadsheet that automates the calculations. The following steps outline the general procedure for performing venturi scrubber design calculations using XLS:
: Calculates the psychrometric changes as hot raw gas is saturated before entering the throat. ratio may offer a more energy-efficient optimization pathway
: Uses Hesketh or Young equations to calculate the energy requirement, which is critical since venturi scrubbers often operate at high pressure drops (10–25 inches of water). Critical Design Parameters Included
