Analisis Kinerja Genset Berbahan Bakar Biogas Dan Biometan Pada Unit CLPDTR

Abstract

Biogas is the main products from anaerobic processing of cattle dung in Continuous Longitudinal Plate Digester Tank Reactor. With CO2 absorber, biogas is improved to be biomethane using NaOH. Biogas and biomethane proven can be used on engine motor by adding converter and simple regulator. With composition of methane 50%-65%, biogas and biomethane can produce electricity with capacity 1kW/h. Generator set testing with load electricity addition (200, 400, 600, 800, dan 1000) watt and ratio variety of LPG addition ( 0:5, 1:4, 2:3, 3:2, 4:1, and 5:0). Optimum mixing of the ratio is 2:3 on 800 watt. It is proven by looking at the power generated, torque dan Specific Fuel Consumption. For biogas, it is obtained 0.888kW, 2,871 Nm and 1.007 kg/Hp.h, while biomethane is obtained 0.862kW, 2,772 Nm and 0.986 kg/Hp.h.
