Abstract
(Muhammad Noble Hidayatullah, 58 Halaman, 24 Tabel, 28 Gambar, 4 Lampiran) Salah satu dari sekian banyak sumber daya alam yang dapat didorong penggunaannya menjadi energi alternatif diantaranya adalah energi alternatif yang berasal dari biomassa. Cara termudah mengubah limbah biomassa cangkang kelapa sawit menjadi energi yaitu dengan membakarnya langsung. Tetapi nilai kalor yang terkandung relatif masih rendah sehingga untuk meningkatkan nilai kalornya dapat dilakukan proses pirolisis. Dari proses pirolisis dapat dihasilkan asap cair atau bio-oil serta arang karbon yang dapat digunakan dan bernilai ekonomis. Selama ini untuk memproduksi asap cair dilakukan pirolisis tanpa menggunakan sistem kondensor yang bersirkulasi, sehingga pengkondensasian dari asap cair yang didapatkan kurang maksimal, ditandai dengan masih adanya asap yang belum terkondensasi. Oleh sebab itulah penulis mencoba untuk mengembangkan rancang bangun prototipe pirolisis biomassa dengan mensirklulasikan air pendingin pada kondenser agar asap cair terkondensasi dengan baik. Hasil perhitungan pengaruh laju alir bahan bakar terhadap kehancuran exergi berbanding lurus, semakin besar laju alir bahan bakar, makan semakin besar pula kehancuran exergi. Proses kondensasi pada kondensor dengan laju alir bahan bakar sebesar 5 liter/menit, kehancuran exergi sebesar -7,709 kJ/menit, pada laju alir bahan bakar 6 liter/menit kehancuran exergi sebesar -12,782 kJ/menit dan pada laju alir bahan bakar 7 liter/menit kehancuran exergi sebesar -21,523 kJ/menit. English : (Muhammad Noble Hidayatullah, 58 Pages, 24 Tables, 28 Figures, 4 Appendix) One of many natural resources that the use can be pushed into alternative energy include the alternative energy derived from biomass. The easiest way to change the oil palm shell waste biomass into energy is by burning it directly. But the heating value contained relatively low so as to increase the calorific value of the pyrolysis process can be carried out. From the pyrolysis process can be produced liquid smoke or bio-oil and charcoal carbon that can be used and have economic value. Previously to produce liquid smoke made without the use of condenser circulating system, so that condensation of liquid smoke obtained less than the maximum, characterized by the presence of smoke that has not condensed. That’s why the author tries to develop engineering prototypes pyrolysis of biomass with circularized cooling water in the condenser so that the liquid smoke condensed well. The results of the calculation of the effect of the fuel flow rate is directly proportional to the exergy destruction, the greater the fuel flow rate, the greater the exergy destruction. The process of condensation on the condenser with a fuel flow rate of 5 liters/min, the destruction of exergy -7.709 kJ/min, the fuel flow rate of 6 liters/min destruction of exergy -12.782 kJ/min and at a flow rate of materials fuel 7 liters/min destruction of exergy -21.523 kJ/min.
