Abstract
Abstract
The corrosive geothermal fluids combined with high temperature and high-pressure work systems cause intensive corrosion. Corrosion that exceeds the safe limits can cause gas leaks which are hazardous to the environment and personnel. It is important to inspect the location of corrosion in the equipment. The existing methodology for inspection is carried out regardless of the risk level of the equipment. Therefore, it is necessary to apply the appropriate method to conduct inspections based on risk level. This research proposed a Risk-Based Inspection method to determine the scheduling and methods for inspecting scrubber vessel in the gas removal system of the geothermal power plant. Based on the analysis, it is recommended to carry out direct inspection for the shell part of the steam scrubber (VS-81-009) using radiography or ultrasonic scanning.
