What is Glycol Calculator?
Glycol Calculator is a tool used in the oil and gas industry to precisely calculate how much glycol is necessary to remove specific amounts of water vapor from gas streams. It’s especially popular for natural gas processing and dehydration processes.
Glycol Flow Rate (GFR) = (W∗M∗G)/24
where:
- W = Water vapor content of gas in pounds per million standard cubic feet (lb/MMscf)
- M = Gas flow rate in thousand standard cubic feet per hour (Mscf/h)
- G = Amount of glycol needed to remove one pound of water in gallons
To use the Glycol Calculator, follow these steps:
- Determine the water vapor content of the gas stream in pounds per million standard cubic feet (lb/MMscf).
- Determine the gas flow rate in thousand standard cubic feet per hour (Mscf/h).
- Determine the amount of glycol needed to remove one pound of water in gallons.
- Plug the values into the formula: Glycol Flow Rate (GFR) = (W * M * G) / 24.
- Calculate the result using a calculator or by hand.
For example, let’s say we have a gas stream with a water vapor content of 10 lb/MMscf, a gas flow rate of 1000 Mscf/h, and a glycol requirement of 0.1 gallons to remove one pound of water. Using the formula above, we can calculate the glycol flow rate as follows:
GFR = (10 * 1000 * 0.1) / 24 = 41.67 gallons per hour (GPH)
Therefore, a glycol flow rate of 41.67 GPH would be required to remove the specified amount of water vapor from the gas stream.
In conclusion, the Glycol Calculator is an invaluable tool for oil and gas industry professionals to accurately determine how much glycol they need to remove water vapor from gas streams.
The formula involves taking into account water vapor content of gas, flow rate, and amount of glycol needed per pound removed. By following these simple steps outlined above, one can quickly calculate exactly how much glycol flow rate is necessary for any given stream of gas.
