ADI Systems Asia Pacific is pleased to announce a second engagement by Wings Corp for the design, construction, and installation of a waste-to-energy plant at its palm oil mill in Jorong, South Kalimantan, Indonesia.
The waste-to-energy plant will be built by PT Gawi Makmur Kalimantan. Biogas will be produced from the fermented Palm Oil Mill Effluent (POME) and utilized as a fuel. The biogas will be utilized in a gas engine to produce electrical power to be used by the mill, replacing diesel generators.
The ADI-CGR® selected for this project is an engineered high yield in-ground anaerobic system used predominantly for bioenergy production (in the form of biogas). The design of the system facilitates efficient mixing between the anaerobic sludge and the feedstock, and separates the hydraulic and solids residence times to maximize biogas production and solids breakdown. The large volume of the ADI-CGR® offers extended biomass contact and good process stability, especially in comparison with smaller, lower capital cost systems which suffer from process instability as they age.
In addition to biogas, the reactor generates a liquid effluent and a higher solids waste sludge. The liquid effluent can be irrigated onto farm land as a nutrient supplement, or further treated with aerobic polishing to achieve higher quality final effluent parameters. The waste sludge, largely made up of biomass and digested solids, is nutrient-rich, stable, and suitable for land application as fertilizer.
Biological commissioning is expected to begin in February 2016 with the plant producing sufficient biogas to supply 2.3 MW of electrical power by May 2016.
Power generated by the biogas internal combustion engine will displace fossil fueled diesel generation. Excess power will be exported to the local distribution network grid and supplied to the surrounding villages that currently have no access to grid electricity. This will facilitate additional secondary regional development.
Approximately 720,000 liters of diesel consumption per annum will be displaced by biogas fuel. Carbon dioxide equivalent emissions will be reduced by utilizing methane from biogas instead of fossil fuel. Approximately 1.3 million cubic meters of methane emissions, which is equivalent to 18 million tonnes of C02, is reduced through biogas consumption. Approximately 1.8 million tonnes C02 equivalent of diesel consumption is foregone. This net result is a reduction of approximately 20 million tonnes of C02 equivalent emissions per annum.
