As air at atmospheric pressure is compressed, it becomes saturated with water vapor. This happens even when the relative humidity is low. Moisture in air lines can cause valves, regulators, and controllers to freeze up. At this moment of time moisture separators are required. Moisture separator is a aluminum coveres cylindrical vessel designed to separate condensate from the compressed air stream.
The Moisture Separator determines the properties of the gaseous mixture at the entrance and the flow rate and properties of flow to and from the Drain Tank. Moisture separator consists of a tank and each of this tank comprises moisture separator drain tank. A saturated tank keeps the track of saturated conditions.
For efficient working moisture separator tracks the following quantities:
- Pressure in tank
- Tank quality
- Tank enthalpy
- Tank water mass and level
- Velocity of liquid falling inside of the moisture separators,
which will affect liquid holdup in the moisture separator
- Admittance of liquid draining to the feedwater heaters or condenser.
