Abstract

Energi gas buang mesin kapal nelayan yang terbuang keudara bebas belum dimaanfaatkan, sehingga didesain alat destilasi air laut menjadi air tawar yang dapat digunakan nelayan. Tujuan penelitian ini adalah menghasilkan prototipe destilator memanfaatkan energi gas buang mesin Diesel, menghasilkan air tawar untuk kebutuhan nelayan, meningkatkan produktivitas nelayan saat berlayar dapat mengolah air laut menjadi air tawar dan mengetahui produk uap dan air tawar pada ruang evaporasi destilator tipe dua atap miring. Penelitian ini menggunakan metode eksperimen. Destilator didesain sebagai alat destilasi air laut dengan memanfaatkan energi gas buang mesin Diesel. Menganalisa produksi uap air dan produk air tawar pada ruang evaporasi. Hasil penelitian selama 3 jam dengan volume air laut 25 liter diperoleh : Pada putaran mesin 2200 rpm, produk air tawar 4,07 kg, produk uap 4,24 kg, temperatur gas buang 228 oC, temperatur air laut 89 oC, kalor sensibel maksimum 1,609 kJ/s, kalor laten maksimum 1,276 kJ/s dan kalor kondensasi maksimum 1,356 kJ/s. Pada putaran 2000 rpm, produk air tawar 3,34 kg, produk uap 4,075 kg, temperatur gas buang 209 oC, temperatur air laut 87 oC, kalor sensibel maksimum 1,727 kJ/s, kalor laten maksimum 1,14 kJ/s dan kalor kondensasi maksimum 1,12 kJ/s. Pada putaran 1800 rpm, produk air tawar 2,62 kg, produk uap 3,001 kg, temperatur gas buang 185 oC, temperatur air laut 83 oC, kalor sensibel maksimum 1,551 kJ/s, kalor laten maksimum 0,903 kJ/s dan kalor kondensasi maksimum 0,911 kJ/s

Abstract

Heat transfer plays an important role in the metal smelting process, so it is important for analysis to be carried out. This study aims to analyze heat transfer in a charcoal-fueled crucible furnace equipped with a blower in the mechanical engineering laboratory, Dayanu Ikhsanuddin University. The experimental method in this study was carried out at a furnace crucible burned with mangrove charcoal and equipped with a blower as a channel to circulate air through a 2-inch tube. Based on the results of the study, the heat from mangrove charcoal fuel is 37985.364kJ, the heat of smelting of aluminum is 1635.24kJ, and the heat absorbed by the walls and cover of the furnace is 29152.76kJ. The heat escaping through the cover, chimney, and other losses is 7197.37 kJ. The efficiency of the charcoal-fueled crucible furnace is 81.05%.

Abstract

This study aims to determine the characteristics and quantity of oil produced from first and second level pyrolysis. The method in this research is an experiment with a pyrolysis tool designed in two levels. The advantage of this pyrolysis tool compared to other pyrolysis tools is that it is expected to produce two fuels with different physical and chemical properties. The results of the study showed that for the first level of pyrolysis PP plastic, 855.7 grams of oil was produced with the following characteristics: density @15°C = 754 kg/m³, final boiling point = 264.9°C, distillation @200°C = 71.8% v/v. while in the second level pyrolysis for the PP plastic type, it produces 138.5 grams of oil with the following characteristics: density @15°C = 718.5 kg/m³, distillation at 10% evaporation volume = 74.4°C, distillation at 50% evaporation volume = 123°C, and distillation at 90% evaporation volume = 142.1°C, final boiling point = 189.7°C. The first level pyrolysis process on HDPE plastic initially only produced 418 grams of oil with the following characteristics: density @15°C = 751.5 kg/m³, final boiling point = 279.4°C, distillation @200°C = 70.9%v/v. The fuel produced from the first level pyrolysis process has characteristics comparable to kerosene, while the fuel produced in the second level pyrolysis process has characteristics equivalent to 88 octane fuel.
