Description
Summary:The Asset Integrity project is one of the strategic priorities in maintenance to ensure the functional lifetime of an asset is well maintained to support the nickel processing. The coating protection application is one of the asset integrity strategy to maintain the structural lifetime, however the corrosive environment of nickel processing plant influences the lifetime of the coating design differently on each facility due to different process in the processing line. The objective of this study is to predict the coating design lifetime on Dryer, KILN, Furnace, and Converter facilities. The analysis used regression method for coating lifetime on each facility by considering the independent variables, i.e. SO 2 Intensity, stack emission, NOx emission, rainfall intensity, and underfilm condition. By using regression model, coating design lifetime in Dryer area is 4.95 years, KILN is 5.73 years, Furnace is 6.23 years, and Converter is 6.73 years. Process plant area which having the most significant impact of corrosive environment is Dryer area, causing the coating lifetime in this area is the lowest than other area in the Process Plant area. This result can be used to set maintenance strategy for coating design lifetime lifecycle for the next Asset Integrity project.
