There are gas turbines running is NG fuel. gas booster compressor is there before gas turbine which compress the NG upto 18kg/cm2 with a surge vessel at the gas booster compressor outlet. The size of the Ng surge vessel is around 100m3.
Today I was standing nearby surge vessel (it is a standard vessel with a tubular shape, 4m dia, 8m long approx.) at the middle portion on ground. the vessel is installed at ground level with concrete base vacant at middle part. I observed a humming sound from the vessel is coming which did not last for more than 10sec. later on I tried to check whether it is coming again but I did not found it.
Can any one have any idea about this type of phenomenon?
