Abstract:
A method for controlling the level of water in a fuel gas saturator comprising the steps of:determining a proportion of the water in the moisturized fuel gas supplied by the gas saturator; determining a flow rate of dry fuel gas entering the gas saturator; determining a flow rate of the portion of water in the moisturized fuel gas supplied by the gas saturator without direct flow measurement of the moisturized fuel gas; and adjusting a flow of make-up water entering the fuel gas saturator in accordance with the determined flow rate of the water portion in the moisturized gas exiting the gas saturator to control the level of water in the fuel gas saturator thereby to maintain a stable level of water in the fuel gas saturator throughout all steady state and transient operating conditions.
