You must calculate the cross-sectional area of the tower based on the gas flow rate and the flooding velocity. Operating velocities typically range from 50% to 80% of the packing's flooding point. 2. Number of Transfer Units (NTU)

Data from process simulators (like Aspen HYSYS) can be directly imported for optimization. 2. Key Components of a Scrubber Design Excel Model

The is a widely accepted model for Venturi pressure drop:

❌ (e.g., ft³ and m³). ✅ Solution: Convert all inputs to a consistent base unit system (SI or US) at the input stage using helper columns.

Here is a practical workflow for creating a scrubber design calculation sheet in Excel:
