The formula to calculate the Glycol Flow Rate (GFR) is:
\[ GFR = \frac{W \times M \times G}{24} \]
Where:
Glycol flow rate refers to the rate at which glycol is circulated in a system to remove water vapor from gas. It is calculated by multiplying the water vapor content by the gas flow rate, then multiplying by the amount of glycol needed to remove one pound of water, and finally dividing by 24. This metric is crucial in processes like natural gas dehydration.
Let's say the water vapor content (W) is 0.1, the gas flow rate (M) is 500, and the amount of glycol needed to remove one pound of water (G) is 3. Using the formula:
\[ GFR = \frac{0.1 \times 500 \times 3}{24} \approx 6.25 \, \text{gallons/hour} \]
So, the glycol flow rate (GFR) is approximately 6.25 gallons/hour.
