Q2 A biogas plant has been proposed to setup for 25 workers staying in a village near Al-wadi. Each person needs 528 liters of biogas for cooking. If the retention period is 46 days, what capacity of the digester should be designed? How much biogas will be generated per day? How much energy does the plant generates in a year? How many cattle are required to produce the required waste? Take the specific gravity of the slurry as 1.165 gram/cm. Take ratio of animal waste to water as 1:1.2 for making slurry. Mention, which type of digester suits well for efficient gas generation? Justify your answers with valid reasons. what percentage of gas storage volume will be occupied, if you are using (1) fixed dome type digester (i) floating drum type and (ii) and balloon type digester?
