Analysis of the Effects of CO2, H2S Composition, and Temperature on Steam Towards Corrosion Rate in Geothermal Power Plants
Firdaus, muhammad Rafsya , Hidayati, Noor, Ekayuliana, Arifia
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 ...
