Transfer Processes

The main purpose of this project was to simulate heat transfer processes inside a biogas plant. The unique design of the suggested biogas plant incorporates a heat exchanger mixer as one combined part. This allowed more even biomass warming and keeping the required temperature level all over the tank to optimize the overall biogas processing in the plant. The research results show how major biogas plant parameters affect the plant performance.

Economic Balance

A centralized biogas plant was built in Shikaoi town, Hokkaido, Japan to treat manure from 1320 cattle heads. The biogas plant was designed to operate at a feeding amount of 85.8 t/day, a hydraulic retention time (HRT) of 37 days and at a digester temperature of 38 ?C. In this study, the operational performance of biogas plant, utilization of digested slurry and economic balance were investigated. Since the working conditions of the plant became stable, the biogas production was 2,687 m3/day, 92% of produced biogas was consumed in power generation. Average methane concentration in produced biogas was 57.7%. The hydrogen sulfide (H2S) concentration was decreased to below 140 ppm as a result of bio-desulfurization and dry-desulfurization. The average power generation was 3,737 kwh/day and from that 54% of produced biogas was consumed in the facility operation, while 46% was sold to Power Company. About 20,260 t of digested slurry were applied onto 602 ha grassland and agricultural fields. From the results of the operational performance of the plant and the economic balance evidence, it is evident that the centralized biogas plant has a positive effect on the local economy.

Valve Control

Biogas plants are slowly becoming popular as these are non- polluting, renewable energy source, reduces landfill and inexpensive. However, users from rural populations are still facing problems due to the absence of automation in biogas plants. Hence, the demand for automation and control is increasing so as to enhance the plant performance. This paper proposes a hardware implementation of automatic gas valve control mechanism for biogas plant. The automatic gas valve control system consists of LC5926H ON - OFF controller by which an automatic opening and closing of the gas valve has been carried out via solenoid valve. Based on the pressure inside the dome, the controller allows solenoid valve to perform the switching operation if the pressure inside the dome exceeds or fall below the preset value. This advanced mechanism provides more efficient and reliable solution to the existing biowaste systems by reducing human intervention and by avoiding the gas leakage.
