Explain the importance of 'nitrogen blanketing' in geothermal power plant equipment during shutdown periods.

Nitrogen blanketing, the process of filling the void spaces in geothermal power plant equipment with nitrogen gas during shutdown periods, is crucial for preventing corrosion and preserving equipment integrity. When equipment is shut down, the internal surfaces are exposed to air, which contains oxygen and moisture. These elements can react with the metal surfaces, leading to corrosion. The presence of geothermal fluids, even residual amounts, can exacerbate this c....
