The following section details the specific formulas and logic flows to be implemented in the Excel spreadsheet.
The L/G ratio determines the number of scrubbing droplets.
) using a psychrometric chart or humidity ratios. The scrubber is sized based on this saturated outlet volume, not the hot inlet volume. Target Efficiency : Define the required collection efficiency (e.g., for particulates) based on regulatory standards. 2. Determine Column Diameter The column diameter ( ) is primarily a function of the gas velocity required to avoid flooding while maintaining contact time. Calculation scrubber design calculation excel hot
= (0.000585/vr) * SQRT(sigma/rho_l) + 0.0597 * (mu_l / SQRT(sigma/rho_l))^0.45 * (Ql/Qg)^1.5
For gas absorption, packed bed towers are standard. The cross-sectional area ( ) is determined based on the gas velocity ( Vgcap V sub g The following section details the specific formulas and
where v is the superficial gas velocity ( typically 1-3 m/s).
A=Qsat3600⋅Vgcap A equals the fraction with numerator cap Q sub s a t end-sub and denominator 3600 center dot cap V sub g end-fraction The scrubber is sized based on this saturated
Use Excel formulas to calculate gas density at hot temperatures using the Ideal Gas Law ( 2. Saturation & Cooling Calculations
This comprehensive guide details the design engineering principles for hot gas wet scrubbers and provides a structured blueprint to build your own verification calculation sheet in . 1. Thermodynamic Fundamentals of Hot Gas Scrubbing
