Abstract

Liquefied Petroleum Gas (LPG) merupakan salah satu bahan bakar alternatif yang saat ini semakin banyak digunakan. Distribusi LPG memiliki model rantai pasok yang kompleks, mulai dari offshore platform, tanker LPG, terminal LPG, SPBBE hingga end user, yang masing–masing memiliki peran krusial. Pada terminal LPG, pompa LPG yang menyalurkan LPG dari storage tank ke truk tangki memegang peran yang sangat penting guna menjamin kelancaran pasokan LPG. Sehingga pompa harus dioperasikan pada titik paling optimum. Tugas akhir ini menyajikan analisis terhadap performa pompa LPG di Terminal LPG Semarang, khususnya sistem penyaluran LPG, untuk mendapatkan konfigurasi dan kecepatan operasional pompa yang dapat menghasilkan performa paling optimum. Analisis dilakukan dengan menggunakan software MATLAB dengan cara mem-plot-kan persamaan kurva pompa dan kurva sistem. Oleh karena itu terlebih dahulu harus mendapatkan persamaan kurva - kurva pompa pada seluruh tingkat kecepatan dan semua jumlah pompa, yaitu paralel 2, 3, dan 4 pompa. Sedangkan kurva sistem diperoleh berdasarkan pemodelan pada software Pipe Flow Expert. Berdasarkan hasil plotting kurva – kurva tersebut, diperoleh titik kerja setiap paralel pompa, yaitu diperoleh nilai debit total, head, serta debit, efisiensi dan power input masing – masing pompa. Selain itu, debit dari setiap konfigurasi harus memenuhi beberapa batasan, yaitu debit maksimum Truck Loading Arm, batas debit sesuai operating manual, dan rekomendasi API 610. Hasil akhir analisis menunjukkan bahwa konfigurasi 3 pompa pada kecepatan putaran 100 % menghasilkan debit paling tinggi pada semua level tangki dan memenuhi batasan yang disyaratkan, yaitu total 344,2 m3/h pada level tangki 19 m, 337,3 m3/h pada level 12 m, dan 330,8 m3/h pada level 5 m ====================================================================================================== Liquefied Petroleum Gas (LPG) is one of the alternative fuel are now more widely used. LPG distribution has a complex supply chain models, ranging from the offshore platform, LPG tanker, LPG terminal, LPG Station to the end user, each has a crucial role. At LPG terminal, LPGpumps that transfer LPG from the storage tanks to tanker holds / skid tanks a very important point to ensure the smoothness of LPG supply. So that the pump should be operated at the optimum point. This thesis presents performance analysis of the LPG pump at Semarang LPG Terminal, especially LPG transfer system, to get the best configuration and operational speed pumps that can produce the most optimum performance. Analyses were performed using MATLAB software by plotting both of the equation of the pump curve and system curve. Therefore, it must first obtain equations of the pump curves at all of speed levels and the number of pumps, namely parallel 2, 3, and 4 pumps. While the system curve is obtained by modeling on the Pipe Flow Expert software. Based on the results of curves plotting, obtained the working point of each parallel konfiguration, the values obtained total discharge, head, as well as debit, efficiency and power input of each pump. In addition, the discharge of any configuration must meet several limitations, namely the maximum discharge of Truck Loading Arm, appropriate discharge limits operating manual and the recommendations of API 610. The final results of analysis showed that the configuration of the 3 pumps at rotational speed of 100 % will produce the highest discharge at all levels of the tank and meet the limitation are required, that’s a total of 344.2 m3/h at the level of the tank is 19 m, 337.3 m3/h at the level of 12 m, and 330.8 m3/h at the level of 5 m.
