Air Stripping Units Installation: Determining Air Flow Rate Ratio

What is the ratio of the two air flow rates for the air stripping units being installed at industrial sites?

The ratio of the two air flow rates can be determined by considering the stripping factors and the flow rate of each unit. Given that the stripping factors are the same and the flow rate is 100 L/min, the ratio of the air flow rates is equal to the ratio of the volumes of the contaminants. The density of toluene and trichloroethylene needs to be considered to calculate the ratio.

Understanding Air Stripping Units

Air stripping units are commonly used in industrial settings to remove contaminants from water sources. The efficiency of an air stripping unit is measured by its stripping factor, which is the ratio of the volume of air required to remove a unit volume of contaminant. In this case, both units have a stripping factor of 6.

Calculating Air Flow Rate Ratio

To determine the ratio of the two air flow rates, we need to compare the volumes of toluene and trichloroethylene being stripped. Since both units have the same flow rate of 100 L/min, the ratio of the air flow rates is directly related to the ratio of the volumes of the contaminants.

Determining Contaminant Volumes

Toluene and trichloroethylene have different molar masses, so their densities (ρ) must be taken into account to calculate their volumes. Let's assume the density of toluene is represented by ρ_toluene and the density of trichloroethylene by ρ_tce. Ratio Calculation:
Ratio = (ρ_toluene / ρ_tce) By determining the densities of toluene and trichloroethylene, the ratio of the two air flow rates for the air stripping units can be accurately calculated.
