FUEL GAS MOISTURIZATION SYSTEM LEVEL CONTROL

The composition of moisturized fuel gas exiting a fuel gas saturator is controlled using feed forward control. The level of the water is manipulated by adjusting the valve that controls the make-up water. The level controller uses the moisture content of moisturized fuel gas, the flow rate of the dr...

Zusammenfassung:	The composition of moisturized fuel gas exiting a fuel gas saturator is controlled using feed forward control. The level of the water is manipulated by adjusting the valve that controls the make-up water. The level controller uses the moisture content of moisturized fuel gas, the flow rate of the dry fuel gas entering the fuel gas saturator, the level of the water at the bottom of the fuel gas saturator and the flow rate of the make-up water to control the valve. Moisture content of the moisturized fuel gas and the flow rate of the dry gas entering the fuel gas saturator are used to calculate the flow rate of water leaving with the moisturized fuel gas. Error is minimized in determination of the flow rate of water leaving with the moisturized fuel gas, thereby allowing tighter control over the process unit.
