Venturi Scrubber Design Calculation Xls Upd _verified_ May 2026

To design a Venturi scrubber and build an automated calculation spreadsheet, you must focus on three core areas: gas humidification throat sizing (based on required efficiency), and pressure drop estimation 1. Identify Target Efficiency and Throat Velocity

Using this template, designers can quickly and easily perform venturi scrubber design calculations and evaluate the impact of different design parameters on performance. venturi scrubber design calculation xls upd

VenturiEfficiency = Eff * 100 End Function
  • Enter the liquid flow rate and properties (e.g., density, viscosity).

Results: Summary of throat dimensions, power requirements (BHP), and total L/G needed. To design a Venturi scrubber and build an

Dim k As Double ' Empirical constant k = 0.00015 ' Typical value depending on geometry
  • Stk = (rho_p * dp^2 * V_t) / (18 * mu_g * D_t) (check units)
  • Single-droplet capture efficiency via empirical functions: eta_impaction = f(Stk, droplet size ratio); implement simple curve such as eta = 1 - exp(-a * Stk^b) with defaults
  1. Yellow cells = user inputs (gas flow, throat area, liquid loading, particle size distribution).
  2. Green cells = calculated results (ΔP, η, throat velocity).
  3. Always verify with pilot test data – the spreadsheet is for preliminary design & education.
  4. For high-temperature or corrosive gases, adjust the density & viscosity inputs accordingly.
