: Hot gas often requires exotic alloys or specialized FRP (Fiber Reinforced Plastic). Ensure your Excel includes a "Material Factor" lookup table.
To help tailor a template or specific equations for your project, please share a few more details: What are you looking to remove? What is the estimated inlet temperature of your hot gas?

A scrubber is a type of air pollution control device that uses a liquid to remove contaminants and pollutants from a gas stream. The design of a scrubber involves several key calculations to ensure that it can effectively remove pollutants and meet emissions standards. In this write-up, we will discuss how to perform scrubber design calculations using Excel.
Before finalizing your Excel sheet design, run a baseline verification check:
