Abstract

Pada industri minyak dan gas, sistem perpipaan merupakan komponen penting untuk mendukung proses transfortasi fluida seperti minyak mentah dan gas alam, namun dalam proses transfortasi sering kali membawa kotoran, debu, ataupun partikel padat lainnya. Fluida yang mengandung partikel padat dapat menyebabkan masalah serius dalam sistem perpipaan, oleh karena itu dibutuhkan strainer sebagai penyaring partikel padat tersebut. Meskipun strainer berfungsi sebagai penyaring, adanya strainer di jalur aliran dapat menimbulkan dampak terhadap karakteristik aliran fluida salah satunya adalah penurunan tekanan. Maka studi dinamika fluida menjadi penting dalam memahami fenomena aliran di sekitar strainer guna mengidentifikasi dan mengatasi permasalahan tersebut. Metode yang digunakan pada penelitian ini adalah pendekatan simulasi numerik Computational Fluid Dynamics (CFD) dengan geometri strainer Dp=8 dan 6 inci, diameter lubang d=6 dan 4 mm, tipe lubang staggered dan straight, ketebalan s=2mm dan fluida uji gas metana. Hasil simulasi menunjukkan pada strainer Dp 8 inci (OAR=30,68%), tipe lubang staggered dengan q=81 menghasilkan DP paling kecil yaitu 169,80 Pa. Sedangkan DP terbesar terjadi pada strainer Dp 6 inci (OAR=19,59%, tipe lubang straight dengan q=830  yaitu 1734,06 Pa.

Abstract

Transportation of hydrocarbon gas in industry often carries contaminants such as scale, rust, and weld metal particles that can disrupt the flow and damage components such as compressors. Strainers are used to filter impurities before the fluid enters the main system. At high flow rates, strainers, especially perforated plates, are susceptible to structural damage. Because experimental tests are expensive and risky, Finite Element Analysis (FEA) simulations are used. This study analyzes the effect of variations in methane gas flow rates on the strength of carbon steel strainers with plate thicknesses of 0.8 mm, 1 mm, and 2 mm. The tested velocities were 7.59 m/s, 9.59 m/s, and 11.59 m/s at a pressure of 10 bars and a temperature of 55?. The results showed the highest stress at the base of the strainer: 32,826 N/m2 (0.8 mm), 30,472 N/m2 (1 mm), and 21,975 N/m2 (2 mm). The maximum deformations occurred at the strainer tip: 2.35×10-8 m, 2.91×10-8 m, and 2.82×10-8 m. All values are below the yield strength limit of carbon steel (2.5×108–5×108 N/m2), indicating a safe design against high flow loads.
