Embodiments of the present disclosure include methods, systems and program products for controlling a water bath heater for a fuel gas. Methods according to the present disclosure can include: calculating at least one calculable condition of the fuel gas based on a set of conditions of the fuel gas entering the water bath heater and a type of control valve located downstream of the water bath heater; calculating a target temperature differential for the fuel gas based a set of conditions of the fuel gas entering the water bath heater and the at least one calculable condition; and adjusting an operating parameter of the water bath heater to adjust a temperature of the fuel gas leaving the water bath heater by the target temperature differential.
1. A method for controlling a water bath heater for a fuel gas, the method comprising:
calculating at least one calculable condition of the fuel gas based on at least one first condition of the fuel gas entering the water bath heater and identified component types located downstream of the water bath heater;
calculating a target temperature differential for the fuel gas based on at least one second condition of the fuel gas entering the water bath heater and the at least one calculable condition; and
adjusting an operating parameter of the water bath heater thereby adjusting a temperature of the fuel gas leaving the water bath heater by the target temperature differential.
2. The method of claim 1 , wherein the at least one first condition of the fuel gas includes a temperature of the fuel gas entering the water bath heater.
3. The method of claim 1 , wherein the at least one second condition of the fuel gas includes a pressure of the fuel gas entering the water bath heater.
4. The method of claim 1 , wherein the calculating the at least one calculable condition of the fuel gas includes using a model selected based on the identified type of the component.
5. The method of claim 4 , wherein the at least one calculable condition includes a hydrate formation temperature.
6. The method of claim 1 , wherein the adjusting the operating parameter of the water bath heater includes increasing a fuel flow used by the water bath heater to heat the fuel gas.
7. The method of claim 1 , wherein one component of the identified component types is a control valve, and
wherein the method further comprises determining whether to replace the control valve based on at least one third condition of the fuel gas.
8. The method of claim 7 , wherein the at least one third condition includes a pressure change of the fuel gas across the control valve located downstream of the water bath heater.
