Scrubber Design Calculation Excel Best Jun 2026
The sheet should highlight conditional formatting warnings if your design features a wetting rate that is too low, or if the superficial gas velocity goes beyond correlation ranges.
Excel struggles with complex, non-ideal chemical interactions. For highly non-isothermal gas absorption or multi-component chemical reactions, secondary verification via simulation software (like Aspen Plus or ProMax) is highly recommended.
The most effective scrubber design calculation tool in Excel should balance detailed with hydraulic limits , such as flooding and pressure drop. A "best-in-class" spreadsheet typically organizes data into clear modules for input, iterative calculation, and results. Core Modules for a Design Spreadsheet scrubber design calculation excel best
Includes detailed calculation methodologies for wet flue gas desulfurization (WFGD) and packed bed scrubbers.
, add a warning note indicating that liquid redistributors are required to prevent wall channeling. The most effective scrubber design calculation tool in
) required for a specific gas absorption efficiency is calculated by multiplying the Height of a Transfer Unit (HTU) by the Number of Transfer Units (NTU). Z=HTU×NTUcap Z equals HTU cross NTU
The purpose of this report is to present the design calculations for a scrubber to remove pollutants from a gas stream. , add a warning note indicating that liquid

Transparency: You can see every formula and understand the physics behind the calculation.
where d L is mean droplet diameter, v r is the relative velocity of gas to liquid, σ is liquid surface tension, ρ L is liquid density, μ L is liquid viscosity, and Q L and Q g are volumetric flow rates of liquid and gas respectively.
