Abstract

Liquefied petroleum gas (LPG) merupakan salah satu bahan bakar yang memiliki peranan penting dalam kehidupan manusia. Di Indonesia, sebagian besar pemanfaatan LPG ditemukan sebagai sumber energi pada rumah tangga dan industri. Kebutuhan LPG yang meningkat mendorong pembangunan fasilitas penanganan muatan LPG, Terminal LPG Semarang salah satunya. Truck loading arm (TLA) venting system merupakan salah satu sistem perpipaan yang terdapat di Terminal LPG Semarang. Sistem ini berfungsi untuk menyalurkan vapor LPG pada prosedur operasional rilis LPG sisa yang berada pada TLA melalui sebuah kompresor menuju storage tank. Akan tetapi, kompresor yang telah terpasang seringkali mengalami kegagalan dalam memindahkan vapor LPG, sehingga aliran mengalami kegagalan yang berujung pada tindakan rilis manual LPG ke lingkungan. Pada penelitian ini, dipelajari mengenai karakteristik aliran berbasis computational fluid dynamic (CFD), analisis tekanan uap LPG pada variasi temperatur, penurunan tekanan, kapasitas aliran, dan daya kompresor yang dibutuhkan pada skenario jumlah TLA yang beroperasi. Hasil analisis menunjukkan bahwa pada kondisi operasi optimal, kapasitas aliran minimum yang dibutuhkan sebesar 0,0511 m3/s dengan daya kompresor minimum sebesar 34,81 kW pada efisiensi politropik 75%

Liquefied petroleum gas (LPG) is a fuel that has an important role in human life. In Indonesia, most of the use of LPG is found as a source of energy in households and industry. The increasing demand for LPG has encouraged the development of LPG cargo handling facilities, Terminal LPG Semarang is one of them. The truck loading arm (TLA) venting system is one of piping systems in Terminal LPG Semarang. This system functions to distribute LPG vapor in the operational procedure of releasing the remaining LPG in TLA through a compressor to the storage tank. However, the compressor that has been installed often fails to transfer LPG vapor, so that the flow fails which leads to manual release of LPG to the environment. In this research, it is studied about the flow characteristics based on computational fluid dynamics (CFD), analysis of LPG vapor pressure on variations in temperature, pressure drop, flow capacity, and compressor power required in the scenario of the number of operating TLAs. The results of the analysis show that under optimal operating conditions, the minimum flow capacity required is 0.0511 m3/s with minimum compressor power of 34.81 kW at 75% polytropic efficiency.
