An interactive web-based Excel-like calculator that provides real-time results for packed bed scrubbers. Features include automatic unit conversion (Nm³/h to actual m³/s), Ergun-style pressure drop calculations, HTU–NTU method for height determination, and flooding checks based on F-factor utilization. The tool is designed to operate at 70–80% of the F-factor limit for stable operation.

Before trusting your spreadsheet for live projects, validate its calculations against known cases. Input data from an existing scrubber and verify that the calculated diameter, pressure drop, and efficiency match actual performance data.

Where m is the equilibrium constant, G and L are gas and liquid flow rates.
This is widely considered the "gold standard" for professional design. It provides the deep theoretical "paper" context while being accompanied by a sophisticated Excel spreadsheet.
