Abstract

CWHE (Cooling Water Heat Exchanger) pada PLTU Tanjung Awar-Awar sering terjadi beberapa permasalahan terutama terkait maintenance yang sulit dilakukan, dimana pada kondisi existing menggunakan tipe PHE (Plate Heat Exchanger). Dalam proyek ini bertujuan untuk menentukan desain cooling water heat exchanger tipe shell and tube yang sesuai kebutuhan PLTU Tanjung Awar-Awar Unit 1.
Tahapan dalam proyek ini meliputi tiga bagian, yakni : 1) Menentukan asumsi desain awal terkait bentuk dan ukuran shell and tube berdasarkan standar TEMA (Tubular Exchanger Manufacturers Association) dan kondisi existing., 2) Menghitung desain shell and tube secara analitis., 3) Melakukan pengoreksian desain analitis menggunakan software ASPEN exchanger design and rating.
Hasil dari penelitian ini didapatkan hasil kesetimbangan energi kalor sebesar 5426721,94 watt, log mean temperature difference sebesar 4,076468281℃, dan luas perpindahan panas sebesar 783,0772924 m2. Dimana atas parameter tersebut didapatkan hasil desain meliputi: diameter tube sebesar 1 in (BWG 8), jumlah tube sebanyak 1254 buah, diameter shell sebesar 1,31169098 m, baffle spacing sebesar 0,4118 m, jumlah baffle sebanyak 18 buah. Desain tersebut telah dilakukan faktor koreksi terhadap nilai overall heat transfer coefficient (U) dengan nilai koreksi perhitungan analitis sebesar 3,8426% dan koreksi perhitungan numerik sebesar 3,27%.

The Cooling Water Heat Exchanger (CWHE) at the Tanjung Awar-Awar Power Plant often experiences several issues, especially regarding maintenance, which is difficult to perform, as the existing condition utilizes a Plate Heat Exchanger (PHE). This project aims to determine the design of a shell and tube cooling water heat exchanger that suits the needs of Unit 1 at the Tanjung Awar-Awar Power Plant.
The stages of this project include three parts: 1) Determining initial design assumptions regarding the shape and size of the shell and tube based on the TEMA (Tubular Exchanger Manufacturers Association) standards and the existing conditions. 2) Calculating the shell and tube design analytically. 3) Performing corrective design adjustments using ASPEN exchanger design and rating software.
The results of this study obtained a heat energy balance of 5426721,94 watts, a log mean temperature difference of 4,076468281℃, and a heat transfer area of 783,0772924 m2. Based on these parameters, the design results include: a tube diameter of 1 inch (BWG 8), 1254 tubes, a shell diameter of 1,31169098 meters, a baffle spacing of 0,4118 meters, and 18 baffles. The design has undergone corrective factors for the overall heat transfer coefficient (U), with an analytical calculation correction value of 3,8426% and a numerical calculation correction value of 3,27%.
