where v is the superficial gas velocity ( typically 1-3 m/s).
To prevent the liquid from being blown out of the top of the scrubber, you must calculate the tower's cross-sectional area based on the gas velocity. Calculate the Flooding Gas Velocity ( Ufcap U sub f ) using the Sherwood-Lobo Correlation . Excel Formula: Set your operating velocity ( Uopcap U sub o p end-sub ) at 60% to 70% of the flooding velocity. scrubber design calculation excel hot
While heavy simulation software (Aspen, HYSYS) is powerful, nothing beats an Excel sheet for rapid iteration, especially for (e.g., exhaust from 150°C to 300°C). Temperature changes density, viscosity, and vapor pressure—if your sheet ignores these, your scrubber will flood or dry out. where v is the superficial gas velocity ( typically 1-3 m/s)
By mastering these calculations, you move from guesswork to precision engineering—ensuring your hot gas scrubber operates safely, efficiently, and without thermal failure. Excel Formula: Set your operating velocity ( Uopcap
