ANALISA KELAYAKAN INVESTASI PROYEK PENGGANTIAN WASH WATER PUMP G-3-02B/D DI PT KILANG PERTAMINA INTERNASIONAL RU V - BALIKPAPAN.

This study aims to enhance the operational reliability and production capacity of the Hydrocracking Complex (HCC) at PT Kilang Pertamina International - RU V Balikpapan by replacing the G-3-02B/D pump, which plays a vital role in the wash water injection process. This pump functions to dissolve Ammonia (NH3) and Hydrogen Sulfide (H2S) from the recycle gas, preventing fouling in the internal tubes of the Combine Feed Exchanger (CFE) and Reactor Effluent Air Cooler (REAC), and maintaining H2 purity and hydrocracking reaction activity. Maintenance data indicates that the G-3-02BD pump has a very low Mean Time Between Failure (MTBF) of 6,257 hours compared to the best practice of 26,280 hours and a Reliability Index of 9.07% compared to the best practice of 71.65%. The investment evaluation method used includes Net Present Value (NPV), Internal Rate of Return (IRR), Payback Period (PP), and Profitability Index (PI). The analysis results show that the pump replacement project has an NPV of $992,590, an IRR of 32.81%, a PP of 2.90 years, and a PI of 2.55. In conclusion, the project is economically feasible. Replacing the G 3-02B/D pump is expected to meet the minimum wash water requirement of 5% vol intake HCU, ensure the reliability of the wash water pump, and support the Daily Processing Plan (RPH) targets, thereby improving the refinery's operational efficiency and reliability.
