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

) is calculated by multiplying the Height of a Transfer Unit ( HTUcap H cap T cap U ) by the Number of Transfer Units ( NTUcap N cap T cap U

Depends on the packing type and fluid velocities. It can be calculated using empirical correlations like the Onda Method, which computes individual gas-side ( Hgcap H sub g ) and liquid-side ( Hlcap H sub l ) transfer units. 3. Excel Spreadsheet Architecture

For standard counter-current configurations, use the logarithmic mean driving force or the integrated Colburn equation to determine NTUyNTU sub y

is calculated considering the friction factor, divergent loss, and acceleration loss of atomizing drops in the venturi tube. The total pressure drop can be expressed as: scrubber design calculation excel best

Created by Genesis Engineers, this workbook is aligned with Chapter 4 ("Absorbers") of Stephen Hall's "Rules of Thumb for Chemical Engineers." It's an excellent resource for those who want to understand the theoretical foundations behind the calculations.

The most common source of scrubber design errors is unit mismatch (e.g., mixing Standard Cubic Feet per Minute (SCFM) with Actual Cubic Feet per Minute (ACFM)).

The column diameter is determined by calculating the gas velocity at which the liquid flowing down the packing becomes entrained in the upward gas stream—a phenomenon known as . Professional designs typically operate at 60% to 80% of the flooding velocity . Step-by-Step Mathematical Sizing Step 1: Calculate the Flow Parameter ( Data from process simulators (like Aspen HYSYS) can

Add a 15% to 20% safety margin to the calculated bed height to account for non-ideal gas distribution in real-world operations.

To build the "best" Excel design calculator, structure your workbook across four dedicated tabs. This maintains clarity, prevents formula corruption, and allows for seamless auditing.

If you need help building a specific section of this Excel model, I can help you with: lists.

While an Excel calculation spreadsheet is excellent for preliminary sizing, conceptual designs, and rapid quoting, it does have limitations: It can be calculated using empirical correlations like

) 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
