Entering gas at high temperatures can crack standard fiber-reinforced plastic (FRP) or ceramic scrubber internals. Ensure your spreadsheet flags inlet temperatures above 250∘C250 raised to the composed with power C
Industrial processes often generate hot waste gases containing hazardous pollutants, particulate matter, and acidic vapors. Designing a wet scrubber for these applications requires precise engineering to handle both chemical absorption and extreme thermal shifts.
The math held. The Excel sheet, messy as it was, had saved the day. pressure drop across the packing for your own design? scrubber design calculation excel hot

Rapid cooling saturates the exit gas with water vapor, creating a visible white moisture plume at the stack. The spreadsheet should calculate down-stream reheating requirements if local environmental regulations prohibit visible plumes. If you want to build this tool, let me know: Entering gas at high temperatures can crack standard
L/G_cool = (Q_sensible) / (Cp_water * Delta_T_water * 8.34)
While the carrier gas volume shrinks, the total gas volume gains a massive amount of water vapor evaporated from the scrubbing liquid. The math held
: Determine based on the allowable gas velocity through the shell (typically 1–2 m/s or 500 ft/min).
