Regarding gas turbines, when is the corrosion rate worse?

Q: In our platform we have three gas turbines to generate electrical power. The fuel for these turbines is supplied from well gas. The gas is sour and wet with the temperature near the dew point. The question is when is the corrosion rate worse, when the gas is heated a little with an electrical heater above its dew point to avoid hydration and a corrosive environment, or when wet gas is not heated even though we know that hydrate is forming in the lines.

A: I am sorry but I am not familiar enough with the operation of gas turbines to render an opinion in this case. I suggest you consult the body of literature on gas turbine operation for further information. One possibility is a book written by Claire Soares entitled "Gas Turbines: A Handbook of Air, Land, and Sea Applications" and published by Butterworth-Heinemann.

Is 304 stainless steel pipe suitable for handling nitric acid?
Is 304 stainless steel pipe suitable for handling nitric acid (10% to 30% concentration) for a continuous duty application?

Which is a better MOC for carbon black plants?
Which is a better MOC for carbon black plants? We crack heavy oils (with sulfur content) at 800 degrees C to produce carbon black. Is 304 better or 316 better to avoid acid corrosion in our pipelines?

Is it better to use a Hastelloy C alloy or 316L stainless steel?
We need to install a level switch probe in 98% sulfuric acid. Based on corrosion resistance, would it be better to use a Hastelloy C alloy or should we use 316L stainless steel? The storage tank temperature is 70 to 90 degrees F and there is no contamination of the acid.

Do austenitic stainless steels have good resistance to carbonic acid attack?
We have a fin-tube style heat exchanger in which we mix natural gas and liquid water, and use an exhaust gas stream to vaporize the water and preheat the fuel mixture. We have a new water recovery process in which we condense the water out of a carbon dioxide rich exhaust stream and feed this into the heat exchanger. It has been observed that the recovered water is slightly acidic at a pH 4.5, and it has been attribute to the presence of dissolved carbonic acid in the water. The tubes of the heat exchanger are 304H Stainless Steel. Is corrosion something we should be concerned about for the long term operation of this unit?
