Scrubber Design Calculation Excel Hot <360p | 8K>

Create an X-Y Scatter chart plotting the Operating Line vs. the Equilibrium Line. This visual check ensures the operating line does not cross the equilibrium line (which would cause pinching and make the design impossible).

To make the spreadsheet functional and user-friendly, incorporate these features:

Standard pressure drop correlations (e.g., Calvert or Semrau) were developed for ambient air. Hot gas has lower density and higher viscosity.

Density Correction: ΔP_hot = ΔP_ambient * (ρ_hot / ρ_ambient)

Excel Formula Example:

= IF(T_in > 200, DeltaP_ambient * ( (1.2) / ( (29/359) * (560/(T_in+460)) ) ), DeltaP_ambient)

Standard scrubber design assumes isothermal conditions or negligible temperature drop. For hot streams (typically >150°F / 65°C up to 1800°F), the physics shift dramatically:

A "cold" spreadsheet fails here. You need an iterative Excel model. scrubber design calculation excel hot

If you want, I can also provide the Excel formulas (e.g., for adiabatic saturation, pressure drop, or d50) so you can implement them directly into cells. Just let me know which module you'd like to start with.

Scrubber Design Calculation using Excel: A Step-by-Step Guide

A scrubber is a critical air pollution control device used to remove pollutants and particulate matter from gas streams. Designing a scrubber requires careful consideration of various parameters, including gas flow rate, pollutant concentration, and scrubbing liquid properties. In this write-up, we will demonstrate how to perform scrubber design calculations using Excel.

Scrubber Design Calculations

The following calculations are typically required for scrubber design: Create an X-Y Scatter chart plotting the Operating Line vs

Excel Calculation Template

Create an Excel template with the following columns:

| Parameter | Input | Formula | Result | | --- | --- | --- | --- | | Gas Flow Rate (Q) | | | | | Velocity | | | | | Scrubber Diameter (D) | | =SQRT(4Q/(PI()velocity)) | | | Scrubbing Liquid Flow Rate | | | | | L/G Ratio | | | | | Scrubber Height (H) | | =( scrubber volume /(PI()(D/2)^2)) | | | Pressure Drop (ΔP) | | =(f L* ρ)/(2*g) | |

Step-by-Step Procedure

Example Calculation

Suppose we want to design a scrubber to treat 10,000 ACM/s of gas with a pollutant concentration of 1000 ppm. The desired removal efficiency is 90%. including flooding velocity

| Parameter | Input | Formula | Result | | --- | --- | --- | --- | | Gas Flow Rate (Q) | 10,000 | | 10,000 | | Velocity | 5 | | 5 | | Scrubber Diameter (D) | | =SQRT(410000/(PI()5)) | 2.26 | | Scrubbing Liquid Flow Rate | 5000 | | 5000 | | L/G Ratio | 0.5 | | 0.5 | | Scrubber Height (H) | | =( scrubber volume /(PI()(2.26/2)^2)) | 5.12 | | Pressure Drop (ΔP) | | =(0.5 5* 1.2)/(2*9.81) | 0.153 |

Conclusion

Scrubber design calculations can be easily performed using Excel. By following the step-by-step procedure outlined above, engineers can quickly evaluate different design scenarios and optimize scrubber performance. This write-up provides a basic template and example calculation to get started. However, it is essential to consult relevant literature and industry experts to ensure accurate and reliable results.
