Abstract: The conversion of husk to usable energy can be accomplished through gasification. Meanwhile, the integration of a gasifier into the rice milling process is beneficial to use the syngas as the energy source. Using the second law of thermodynamics, the mass, energy, and exergy balance at each stream of the system was evaluated. The results showed that a rice miller with 875 kg/h capacity could produce 250 kg/h of rice husk, which can be converted to 353.16 kg/h of producer gas. This is equivalent to 401.53 kW of exergy, higher than the required exergy of the miller.

Keywords: rice husk; rice milling system; RMS; gasifier; energy; exergy.
