Scrubber Design Calculation Excel Hot 〈LIMITED〉

When dealing with hot gas scrubbers, the liquid temperatures inside the column will rise. Standard, cost-effective plastics like Polypropylene (PP) or Polyvinyl Chloride (PVC) soften rapidly above 140∘F140 raised to the composed with power F 60∘C60 raised to the composed with power C

A more robust Excel formula using the : $$ \Delta P \approx \fracu_t^2 \rho_g A_t^0.1331270 \times \left( L/G \right) $$ (Note: Ensure consistent units: Pa or in. w.c.)

where v is the superficial gas velocity ( typically 1-3 m/s).

This is where most "scrubber design excel" downloads fail. They treat volume as constant.

Excel remains the most accessible platform for developing custom engineering calculation tools. The following table summarizes widely available Excel resources for scrubber design:

High-temperature scrubbers often require materials with good creep resistance and oxidation resistance:

Evaporation adds water vapor to the gas stream while cooling drastically reduces its volume. Excel must calculate the final outlet actual volumetric flow rate ( Qactual,outcap Q sub a c t u a l comma o u t end-sub
