Q2) A fixed-dome biogas reactor is to be designed to handle 2000kg/ day of biomass (density of biomass is 1050kg/m3 ) for a total retention time of 60 days. The biogas yield is assumed to be 0.025(m3 biogas /kg biomass). If the maximum rate of gas consumption is 45m3/ day for a period of 15 hours and the maximum time of zero gas consumption is 17 hours. Estimate the following design parameters of the reactor: a) Volume of the digester (m3) b) Volume of the gas holder (m3)
