Scrubber Design Calculation Excel Hot

The Excel sheet should be organized into distinct modules to handle the physics of the scrubber.

For a hot gas stream entering a well-insulated scrubber (adiabatic), the gas will cool to the adiabatic saturation temperature (wet-bulb temperature), assuming sufficient liquid flow and residence time.

The Heat Balance Equation (Imperial Units):

Q_sensible = Q_latent

M_gas * Cp_gas * (T_in - T_out) = M_evap * h_fg

Where:

Excel Challenge: T_out is not known because the humidity ratio changes. You must use Goal Seek or iterative circular logic. scrubber design calculation excel hot

When auditing or fixing a "hot" scrubber calculation in Excel, check for these common pitfalls:

This document outlines the methodology for designing a Venturi Scrubber system intended for hot gas cleaning. The design focuses on removing particulate matter (PM) from high-temperature flue gases using a liquid spray. The accompanying Excel calculation tool utilizes iterative algorithms to determine the throat dimensions, pressure drop, liquid-to-gas ratio (L/G), and overall collection efficiency.

For hot gases, viscosity (μ) increases, which changes collection efficiency. η = 1 – exp[- (ψ * Q_l) / (Q_g * μ)] Where ψ is the inertial impaction parameter. Excel Challenge: T_out is not known because the

Before you trust your spreadsheet for a thermal scrubber specification, confirm these four items:
