The diameter is dictated by the gas velocity. If the velocity is too high, the scrubber will flood; too low, and it becomes inefficient and expensive.
Scrubber design can generally be broken down into key calculation modules. Below is a guide for the three most common types, complete with the core equations you can program directly into your spreadsheet. scrubber design calculation excel best
The height is calculated mathematically by multiplying the by the Height of a Transfer Unit (HTU) : Z=HTU×NTUcap Z equals HTU cross NTU Number of Transfer Units (NTU) The diameter is dictated by the gas velocity
Global Design System Toggle: A cell with data validation ( Metric / Imperial ) to dynamically switch calculation constants across formulas using IF statements. Sheet 2: Process Input Data (User Entries) Below is a guide for the three most
for flooding velocity based on your packing type.
Includes lookups that dynamically adjust the pressure drop per foot of packing to prevent excessive fan energy usage.
