Analisa Laju Erosi Terhadap Lifetime Elbow Di Jalur Pipa Outlet Separator Perusahaan Gas Bumi

Abstract

This can cause friction to collision between the slug particle with the inner wall of the pipe with other components such as elbows, so that it can cause erosion of the pipe system. one of the effects of erosion is the erosion of the inner walls of pipes and their components which in this case is more dominant due to the erosion phenomenon compared to the corrosion phenomenon.The analysis method in this final project is done by manually calculating the minimum wall thickness of material that refers to ASME B31.3 and calculating the erosion rate, the rate of loss of mass per unit area each year to determine the lifetime of the pipe material, elbows in the path, and for visualization of the path of particles causing erosion in each path using the computational fluid dynamics method in ANSYS R19.2 Fluent software.The results of these calculations will be used as material for analysis to determine the feasibility of each component to continue operating in accordance with the design lifetime. The results of the erosion rate in the elbow is 2.7346 mm per year. Where the magnitude of the erosion rate affects the lifetime 1.6 years for elbows.
