• Fertilization/ irrigation • Aerobic treatment and unloading • Disposal into depuration plants

• Organic fertilizer

Cogenerator - CHP

• Thermal combustion engine • Synchronous alternator • Heat recovery, compound from a heat exchanger that recover the heat produced by the whole system, both from the 1st intercooler stage, the cooling water circuit, the 200°C exhausted cooling and the lubricating oil circuit.

• Electric station which allows to use the produced energy for its own consumption and/or connect to the national grid

The Biomethane is a gas derived from biogas that has undergone a process of upgrading (refining and purification), bringing the concentration of methane CH4 to exceed 98 %.

Biomethane: the next step

The advantages of bio-methane: programmable renewable energy reducing the dependence on gas

importations development of the local economy environmental sustainability closed circuit contribute to reducing the gas

emissions (greenhouse effect) maximum flexibility

Field of application: biofuel for motor vehicles put into the national gas pipeline transported and stored for

subsequent energy production even in places far away from the production site

System Data

ENERGY YIELD Annual production of electricity: 8.500.000 kWh Annual production of biogas: 4.100.000 mc Average concent. (CH4) in biogas: 52-54 % GROUP OF CO-GENERATION Manufacturer: AB Energy Model: Ecomax 10 Bio ENGINE Manufacturer: GE Jenbacher Model: J 320 GS–C25

Recovery of the thermal output

THERMAL OUTPUT TO BE DISSIPATED: 77 kWt

TEP equivalent – avoided C02 emission

THERMAL ENERGY • 1082 Kw x 8000hours = 8,656,000 kWh/year • 8,656,000 X 8,803 x 10-5 = 762 TEP (The Rate of conversion of the heat energy in primary energy is equal to 8,803 x 10-5 TEP).

ELECTRIC ENERGY • 999 Kwh x 8400 h = 8,400,000 KWH/year • 8,400,000 X 0.187X10-3 = 1571 TEP (The conversion index of the electric energy in primary energy is equal to 0,187 x 10-3 TEP). Considering that an inhabitant consumes an average of 5300 kWh/year of electric energy, we can estimate that the plant can satisfy the energy consumption of almost 3000 inhabitants.

CO2 EMISSIONS In total, we have a production of approx. 17,056,000 kWh/year of electric and thermal energy. The generated energy is equivalent to a saving of approx. 6437 Ton of CO2 / year (considering 1 kWh386,5 g. of CO2 as indicated by the International Energy Agency.
