Scrubber Design Calculation Excel Hot !!top!!

To prevent the liquid from being blown out of the top of the scrubber, you must calculate the tower's cross-sectional area based on the gas velocity. Calculate the Flooding Gas Velocity ( Ufcap U sub f ) using the Sherwood-Lobo Correlation . Excel Formula: Set your operating velocity ( Uopcap U sub o p end-sub ) at 60% to 70% of the flooding velocity.

For particulate removal (Venturi scrubbers): Typical L/G ranges from 1.0 to 3.0

This module determines the saturated gas flow rate. It utilizes iterative formulas or Excel’s feature to solve the heat balance equation: To prevent the liquid from being blown out

Standard scrubber design assumes isothermal conditions. But when your inlet gas is at 400°C (752°F) or higher, three critical physics problems emerge: But when your inlet gas is at 400°C

The first step is to establish the properties of the incoming hot gas. Because the gas is "hot," you must account for its actual volume at operating temperature rather than standard conditions. Define in ACFM (Actual Cubic Feet per Minute) or Inlet Temperature ( Tincap T sub i n end-sub ): Note the temperature (e.g., 400∘F400 raised to the composed with power cap F 590∘C590 raised to the composed with power cap C
