Requirements for the gas used to operate gas turbine generators

Thread Content

I’m facing a problem at the moment and would like to seek everyone’s advice. I’m working on a project that involves gas turbine generators; once this project is put into operation, fuel gas (natural gas) will be used to power these turbines. The manufacturer states that the gas entering the turbines must be dry gas (dehydrated), whereas in our design we allowed the use of wet gas, provided it had a certain degree of superheat (note: there is a superheating heater in the process flow). In other words, dry gas can be used without the need for superheated gas, but the manufacturer disagrees, saying that this is the requirement specified in their operating manual. Later, I asked mechanical engineers, and they also thought that dry gas should be used, but I still disagree with this view. I hope experienced experts will stop by and offer some advice
