Abstract: Lube oil cooler is a cross flow compact heat exchange which functions to release heat carried by lubricant oil streamed down through shell side to tube side with demineralized water cooler fluid where each liquid was separated inside the lube oil cooler. PT. PLN Generating Sector Belawan is one of the electric power plant unit in North Sumatera region which its performance and reliability has an important role in securing the continuity of electricity supply. Then, this study has been obtained the coefficient ratio of heat exchanger in shell side and tube pipe, also the effectiveness of heat exchanger occurred can be discovered by analyzing the in and out temperature of water cooler flow and lubricant oil can be specified. Moreover, the impact and cause of decreasing performance of lube oil cooler can be discovered. Thus, this study focuses in analyzing data of in and out temperature of water cooler lubricant oil and differential press which reflected from the operational data collected in sheet paper control room at PLTU Belawan.
Description: Abstrak - Lube oil cooler adalah cross flow compact heat exchanger yang berfungsi untuk melepaskan panas yang dibawa oleh minyak pelumas dialirkan melalui sisi shell menuju sisi tube dengan fluida pendingin air demin dimana masing-masing cairan dipisahkan di dalam lube oil cooler. PT. PLN Sektor Pembangkit Belawan merupakan salah satu unit pembangkit tenaga listrik di wilayah Sumatera Utara yang kinerja dan kehandalannya sangat penting untuk menjamin kelangsungan pasokan listrik. Dari penelitian ini, rasio koefisien perpindahan panas disisi shell dan pipa tube serta efektivitas perpindahan panas yang terjadi dapat diketahui dengan menganalisa temperatur masuk dan keluar aliran air pendingin dan minyak pelumas dapat ditentukan. Selain itu dampak dan penyebab penurunan kinerja lube oil cooler dapat diketahui. Penelitian ini berfokus pada analisis data temperatur masuk dan keluar pendingin minyak pelumas dan tekanan diferensial yang tercermin dari data operasional yang dikumpulkan dari ruang kontrol lembar kertas PLTU Belawan.
