Gas Purge Calculator
Definition
- Gas Purge: The number of purge cycles needed to achieve a desired level of purity in a system.
- Significance: Used in various industrial processes to ensure the removal of unwanted gases or contaminants.
Example
Let's say the atmospheric or vent pressure (Pa) is 101325 Pa and the absolute pressure used for the purge (Ph) is 50000 Pa. Using the formula:
\[
GP = \frac{-4}{\log\left(\frac{101325}{50000}\right)} \approx -5.66
\]
So, the gas purge (GP) is approximately -5.66 purge cycles.

Purge Ventilation Calculation
Formula: \( Q = \frac{V}{t} \)
- \( Q \): Ventilation rate (m³/h)
- \( V \): Volume of the space (m³)
- \( t \): Time (h)
Example: \( Q = \frac{500}{2} \)
- Q: Ventilation rate
- V: 500
- t: 2
Well Purge Volume Calculation
Formula: \( V = \pi r^2 h \)
- \( V \): Volume (m³)
- \( r \): Radius of the well (m)
- \( h \): Height of the water column (m)
Example: \( V = \pi \times 0.5^2 \times 10 \)
Pressure Cycle Purging Calculation
Formula: \( P = \frac{nRT}{V} \)
- \( P \): Pressure (Pa)
- \( n \): Number of moles of gas
- \( R \): Universal gas constant (8.314 J/(mol·K))
- \( T \): Temperature (K)
- \( V \): Volume (m³)
Example: \( P = \frac{2 \times 8.314 \times 300}{1} \)
- P: Pressure
- n: 2
- R: 8.314
- T: 300
- V: 1
Boiler Purge Time Calculation
Formula: \( t = \frac{V}{Q} \)
- \( t \): Time (h)
- \( V \): Volume of the space (m³)
- \( Q \): Ventilation rate (m³/h)
Example: \( t = \frac{1000}{200} \)
