Standard scrubber design assumes isothermal conditions or negligible temperature drop. For streams (typically >150°F / 65°C up to 1800°F), the physics shift dramatically: scrubber design calculation excel hot
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%. $$D (m) = \sqrt\fracQ_gas / 36000
$$D (m) = \sqrt\fracQ_gas / 36000.785 \times V_gas$$ 150°F / 65°C up to 1800°F)
, you must calculate the volumetric flow rate of the gas at this lower temperature to size the vessel correctly:
This is the unique differentiator for high-temperature applications (e.g., kilns, incinerators, smelters).
