Final answer:
The Stripping Factor for an air stripping device is calculated using the ratio of the air flow rate to the water flow rate, adjusted by the Henry's Law constant for Benzene. Without the precise value of the Henry's Law constant, we cannot provide a final value for the Stripping Factor, but the calculation would involve multiplying the air flow rate by the Henry's Law constant and dividing by the water flow rate.
Step-by-step explanation:
To calculate the Stripping Factor for an air stripping device, we first need to understand what the term means. The Stripping Factor (S) is defined as the ratio of the flow rate of the gas to the flow rate of the liquid, both of which are usually adjusted to account for the equilibrium partitioning of the contaminant between the two phases. In this case, the contaminant is Benzene.
The formula to calculate the Stripping Factor is:
S = (Qg/Ql) × (H/1)
Where:
- Qg is the flow rate of the air (gas phase)
- Ql is the flow rate of water (liquid phase)
- H is the Henry's Law constant for Benzene at the given temperature (assuming it to be dimensionless here, not provided)
Given that:
- Qg = 219.3 L/min (gas flow rate)
- Ql = 10 L/min (water flow rate)
- H (Henry's Law constant) is not provided but is needed to calculate the Stripping Factor
Assuming we have the value of H, we substitute the known values into the formula to calculate the Stripping Factor as follows:
S = (219.3 L/min / 10 L/min) × (H/1)
Without the value of H, we cannot provide a final value for S, but we can say that the Stripping Factor is proportional to the flow rate of the air and inversely proportional to the flow rate of the water, multiplied by the Henry's Law constant for Benzene.
