Abstract

Abstract – In the separation process for natural gas processing at SKK Migas, there is a sand content that must be separated so that it does not cause erosion in the pipe. To find out the impact of the mass flow rate of sand on the erosion rate in the pipe, it is necessary to do research. In this study, two methods were used, that is measurement and calculation. Det Norske Veritas (DNV) Recommended Practice 0501 was used by using two sample pipe, Blinded tee 3”×2”, and Reducer 3”×2”. Based on the measurement results, the Reducer pipe 3”×2” has better linearity than the Blinded tee 3”×2”. However, the calculation method used Newton's Interpolation. This method can be used to predict the rate of erosion of pipes in very large numbers even with little data. When compared between the measurement results and the calculation results, the Blinded Tee Pipe 3”×2” has an error of 0.368% and the Reducer Pipe 3”×2” has no error at all.
