Abstract

Pembangkit Listrik Tenaga Uap (PLTU) Banten 2 Labuan dengan total kapasitas 2 × 300 MW merupakan salah satu pembangkit listrik yang memanfaatkan energi panas uap bertekanan tinggi. Closed Circuit Cooling Water (C3W) Heat exchanger memiliki peranan penting untuk jalannya sebuah plant, sebagai media pendinginan dan menjaga kestabilan temperatur ditiap peralatan unit pembangkit. Heat Exchanger yang digunakan merupakan jenis Shell and Tube.
Pada tugas akhir ini, proses perhitungan dilakukan dengan menggunakan analisa perpindahan panas dengan Metode Log Mean Temperature Different (LMTD) dan NTU-Effectiveness. Analisa perpindahan panas dan effectiveness digunakan untuk mengetahui performa heat exchanger, dengan membandingkan data spesifikasi dan data aktualnya. Beberapa parameter yang dibutuhkan yaitu inlet dan outlet sea water temperature, inlet dan outlet demineralizer water temperature, dan mass flow rate.
Hasil yang didapat dari tugas akhir ini adalah nilai laju perpindahan panas (q) dan effectiveness (ɛ) CCCW heat exchanger pada data spesifikasi dan data aktual yang diambil di tanggal 21 April 2020. Pada perhitungan data spesifikasi dihasilkan laju perpindahan panas sebesar 11,59538 MW dan efektivitasnya sebesar 0,667297. Kemudian pada perhitungan data aktualnya nilai laju perpindahan panasnya 3,246974 MW dan efektivitasnya 0,633565. Hal ini menunjukkan bahwa performa heat exchanger masih baik dikarenakan perbedaan nilai effectiveness yang kecil.

Steam Power Plant (PLTU) of Banten 2 Labuan with a total capacity 2 x 300 MW is one of the power plants that utilitiez high pressure steam heat energy. Closed Circuit Cooling Water Heat Exchanger (C3W) heat exchanger have an important role for the running of a plant, as a cooling medium and keep temperature stability in each power plant unit equipment. The type of heat exchanger that used is Shell and Tube type.
In this final project, the calculation process is carried out using heat exchanger analysis with the Log Mean Temperature Different (LMTD) and NTU-Effectiveness Methods in the heat exchanger of PLTU Labuan. Analysis of heat transfer and effectiveness is used to determine the performance of the heat exchanger, by comparing the specification data and the actual data. Some of the parameters needed are inlet and outlet sea water temperature, inlet and demineralizer water temperature, and mass flow rate.
The results obtained from this final project are the value of heat transfer rate (q) and effectiveness (ɛ) of CCCW heat exchanger on the specification data and the actual data was taken on April 21,2020. In the calculation of the specification data, the heat transfer rate is 11,59538 MW and the effectiveness is 0 ,667297. Then in calculation of the actual data, the value of heat transfer rate 3,274249 MW and the effectiveness is 0,633565.This shows that the performance of heat exchanger is still good due to the small difference in effectiveness values.
