FALCO 300 Flowrate and Inlet Pressure Calculator (SVE)

rev 5-7-20    This calculator may be applied to any FALCO 300 oxidizer sold after 1/1/2012.  
    This calculator provides an estimate of flow through a FALCO 300 at a catalyst temperature of 330°C with the heat exchanger bypass valve closed*.    
    Alternatively, if the Flow Rate is known, Inlet Pressure can be estimated.  Catalyst Residence Time and Space Velocity may also be calculated.  
Known Inlet Pressure:
Enter Inlet Pressure (in H2O)
Estimated Flow Rate  = (SCFM)
Known Flow Rate:
Enter Flow Rate (SCFM)
Estimated Inlet Pressure = (in H2O)
Space Velocity (GHSV) =
Catalyst Residence Time =
Opening the heat exhanger bypass valve will reduce pressure drop by 
approximately 3-6 in WC.



*FALCO 300 is normally operated with heat exchanger bypass closed at concentrations < 800 ppmv.     
FALCO 300 may be operated with heat exchanger bypass open at high concentrations. Opening the  
bypass lowers heat recovery and reduces pressure drop.

Flow > 360 scfm is beyond the normal operating range. Inlet pressure assumes a clean flame arrestor.

Catalyst volume of the FALCO 300 = 2.5 ft3

Space velocity (GHSV) = Hourly volumetric feed gas flow rate per reaction volume
