Gas turbines run on a range of fuels from downhole gas on an offshore platform to ones that run on clean pipeline grade gas.  If the gas is dirty and wet the need for gas conditioning is obvious.   As it often the case even pipeline grade gas is not consistently clean enough for most of the newer generation DLN turbines.   A Triton particulate and aerosol removing filter upstream of a modern day gas turbine will protect the hot gas path of the turbine.
