Abstract

The corrosion in the steam line pipes at the Geothermal Power Plant is caused by acidic substances present in the steam, especially H2S and CO2, originating from the geothermal reservoir. During operation, this leads to thinning of the pipe walls, affecting the pipe's thickness. The purpose of this research is to calculate the corrosion rate and compare the CO2 and H2S composition in each header using Aspen HYSYS software to determine their influence on the corrosion rate. The research findings indicate that the CO2 and H2S composition in the steam significantly affects the corrosion rate in the steam line pipes. Higher concentrations of CO2 and H2S result in a higher corrosion rate, and the higher the temperature, the corrosion rate will increase.

Abstract

Centrifugal pumps type Overhung 4 size 4x11 often experience sand deposits and erosion problems, especially in the oil and gas industry, resulting in reduced productivity and increased repair costs. This study evaluates the application of the Piping Plan 13 API 682 as a solution to this problem. The 5-Why Analysis method is used to identify the root cause of sand deposits, which were associated with sand contamination from a liquid source and the absence of an effective filtering system. The implementation of Piping Plan 13 aims to prevent sand deposits in critical areas, such as the Pedestal Cover and Pedestals, by leveraging the circulation design of the pipeline. The results showed a 19.75% increase in pump productivity and a 76.12% reduction in repair costs. Productivity increases reached 336,000 barrels (about 53,419,731 liters) over 16 days of operation, while the repair cost fell from Rp6,699,950 to Rp1,600,000. These findings indicate that Piping Plan 13 API 682 is an effective solution to increase the life and performance of the centrifugal pump and reduce maintenance costs in operating conditions with high sand contamination.
