Summary

  • The Biogas Power Plant (BPP) takes in wastes from the nearby farm in the form of pig and chicken manure, as well as other agricultural waste and energy crops transforming them to useful end products – Renewable Energy in the form of electrical power, thermal power, solid fertilizer and liquid fertilizer. The BPP ensures that there will be minimal waste in the plant through fully utilizing all input resources and maximizing the use of all outputs from the BPP.

Summary

  • This work proposes a co-generation system (also known as combined heat and power (CHP)) based on a biomass boiler and an micro-Organic Rankine Cycle (ORC) unit to generate both electrical power, as well as thermal power in the form of hot water.

Process

We can produce electrical power and heat by converting Biomass agriculture waste (such as Corn Cob and Rice Husk) by utilizing the heat from combustion of the biomass into an Organic Rankine Cycle (ORC), in which the organic working fluid has a lower boiling point and higher vapor pressure than water and is therefore capable of producing energy by using low temperature heat sources. Depending on their various thermodynamic properties, the organic fluid is chosen to best fit the heat source, thereby achieving higher efficiencies of both cycle and expander.

Summary

  • The Biogas Power Plant (BPP) takes in wastes from the nearby farm in the form of pig and chicken manure, as well as other agricultural waste and energy crops transforming them to useful end products – Renewable Energy in the form of electrical power, thermal power, solid fertilizer and liquid fertilizer. The BPP ensures that there will be minimal waste in the plant through fully utilizing all input resources and maximizing the use of all outputs from the BPP.

Process

We process the Input Substrate, such as Pig Manure and Chicken Manure, Energy Crop and other waste stream through Anaerobic Digestion. In this AD process, biogas is produced. Methane is the main constituent of biogas. When combusted in the Biogas engines or MicroTurbine, it provides both electrical and thermal energy., A separate by-product of the AD process is digestate, which can be separated into solid and liquid fractions. The solid fraction is soil-like material, which is rich in nitrates and performs well as a fertilizer,while the liquid portion can be used as liquid fertilizer or processed further through the Wastewater Treatment Plant to meet environmental standards prior to discharge.

The Biogas which is produced through Anaerobic Digestion, is used as the fuel for the MicroTurbine and Biogas Engines to produce Electricity. The objective is to reduce greenhouse gas emissions due to the consumption of renewable energy sources and to the adequate waste management.

On the other hand, exhaust gases from the operation of the MicroTurbine is used by Egg Tray Plant to produces recycled environmentally-friendly fiber-moulded egg trays. This solution helps to reduce landfill and conserve the world’s forests.

Summary

  • The purpose of this project was to make beneficial use of the biogas at a chicken egg farm in Singapore to decrease emissions and lower operating costs. Although biogas is considered a carbon neutral fuel, the reduction in emissions comes from the avoidance of emitting methane into the atmosphere by capturing it for use in power generation along with the avoidance of the fossil fuel-based power generation of the utility grid.

Process

The farm has six large climate-controlled layer houses along with two grower houses totaling approximately 600,000 chickens and produces more than 40 tons of chicken waste per day. This waste is used to generate approximately 400 m3/hour of biogas with 57% methane content.

Chicken waste biogas projects historically have been difficult to execute due to the variability of the biogas resulting from the quality of the waste fed into the biodigester. By using microturbine technology we hoped to resolve some of the difficulties related to low methane content, high H2S content, and operational/servicing challenges, while also further reducing the CO2 emissions of the site by making use of the waste heat for drying brewery spent grain for chicken feed.
