) is calculated based on the particle size distribution of the dust. Since scrubbers are more efficient at capturing larger particles, designers use the "cut diameter" ( d50d sub 50 ) method. The d50d sub 50 Pressure Drop Equations The pressure drop ( ΔPcap

A Venturi scrubber consists of three main sections: a converging section, a throat, and a diverging section. The process gas accelerates in the converging section, reaches maximum velocity in the throat where it contacts the scrubbing liquid, and سپس decelerates in the diverging section to recover static pressure.

is the Stokes number, a dimensionless parameter representing the ratio of the stopping distance of a particle to the characteristic dimension of the obstacle (the liquid droplet). Structuring the XLS Tool

To build an accurate design spreadsheet, several critical variables must be accounted for:
