In large power plant, wet steam in turbine and water in turbine oil and wethydrogen in hydrogen-cooled generator will decrease safety and economic of turbine generating unit.
The case was presented to describe corrosion failures of the process equipment in wethydrogen sulfide service in domestic refineries and corresponding measures taken. The precautions were discussed.
