Abstract

Pada KM Napoleon diaplikasikan sistem pendingin Refrigerated Sea Water (RSW). Pendinginan dengan RSW ini dioperasikan selama 2 minggu dan membuat ikan hasil tangkapan me~jadi asin (kadar garam ~ 1%). Oleh karena itu diperlukan suatu sistem untuk menurunkan kadar garam sebelum air laut masuk ke dalam RSW. Pada Tugas Akhir ini direncanakan air laut yang masuk ke dalam RSW mempunnyai kadar garam sebesar 1 %. Untuk mendapatkan kadar garam tersebut dilakukan pencampuran air laut dan air tawar. Air tawar ini dihasilkan dengan menggunakan proses distilasi dengan suatu alat perpindahan panas untuk proses pemanasan dan kondensasi. Pada perhitungan penukar panas tipe spiral fin tube dilakukan variasi inputan temperatur gas buang 200°C, 250°C, 300°C, 350°C, 400° C. Variasi ini digunakan untuk untuk mengetahui dimensi dari penukar panas sebagai acuan peletakannya di dalam kapal. Dari hasil perhitungan pada variasi - variasi temperatur gas huang didapatkan dimensi terbesar adalah pada variasi temperature gas huang 400°C dengan panjang 1,27 m. Posisi peletakan dari heat exchanger adalah dengan posisi vertikal. Peletakan heat exchanger untuk kondensor dikamar mesin sedangkan untuk sea water heater pada aliran pipa gas buang

The KM Napoleon uses a Refrigerated Sea Water (RSW) cooling system. Refrigeration with RSW was operated for 2 weeks and made the caught fish salty (salt content ~ 1%). Therefore, a system is needed to reduce salt levels before seawater enters the RSW. In this final project, it is planned that the sea water entering the RSW will have a salt content of 1%. To obtain the salt content, sea water and fresh water are mixed. This fresh water is produced using a distillation process with a heat transfer device for heating and condensation processes. In the calculation of the spiral fin tube type heat exchanger, the exhaust gas temperature input variations are carried out at 200°C, 250°C, 300°C, 350°C, 400°C. This variation is used to determine the dimensions of the heat exchanger as a reference for its placement in the ship. . From the results of calculations on variations in huang gas temperature, it was found that the largest dimensions were at the huang gas temperature variation of 400°C with a length of 1.27 m. The placement position of the heat exchanger is in a vertical position. Place the heat exchanger for the condenser in the engine room, while for the sea water heater it is in the exhaust gas pipe
