Abstract
Erosi partikel pasir merupakan salah satu permasalahan yang serius dalam industri produksi minyak dan gas. Terdapat suatu bukti kuat bahwa kebanyakan sumur sekarang memproduksi pasir yang semakin meningkat seiring penurunan produksi utama minyak dan gas. Hal ini merupakan masalah yang luas mengingat dapat mempengaruhi laju produksi seiring bertambahnya umur asset. Prediksi erosi yang akurat terutama pada elbow dapat digunakan untuk meningkatkan desain kerja pipa, wilayah inspeksi, limit pengoperasian dan lainnya. Dalam penelitian ini digunakan permodelan CFD pada aplikasi ANSYS Student Version 19.0 untuk memprediksi erosi dalam aliran gas turbulen dengan variasi ukuran partikel pasir dan kecepatan fluida. Didapatkan hasil berupa profil erosi dan laju erosi pada elbow pipa yang dibandingkan dengan hasil eksperimen. Hasil simulasi menunjukkan bahwa CFD mampu untuk memprediksi laju erosi secara baik untuk ukuran partikel 300 µm dengan error sebesar 14.75% dibandingkan ukuran partikel 150 µm yang mencapai error 271.5%. Terbentuk profil erosi berbentuk huruf ‘V’ pada elbow pipa vertikal – horizontal. ========================================================================================================== Erosion of sand particles is one of the serious problems in the oil and gas production industry. There is strong evidence that most wells now produce increased sand as the major oil and gas production declines. This is a widespread problem as it can affect the rate of production as we age the asset. Accurate erosion prediction, especially elbow, can be used to improve pipe work design, inspection area, operating limit and others. In this study, we used CFD modeling in ANSYS Student Version 19.0 application to predict erosion in turbulent gas flow with the variation of sand particle size and fluid velocity. The results obtained were erosion profile and erosion rate in pipe elbow compared with the experimental results. Simulation results show that CFD able to predict erosion rates well for 300 μm particle size with error 14.75% compare 150 μm particle size with error 271.5%. Formed erosion profile in the form of 'V' scar on the vertical - horizontal pipe elbow.
