The plant Murcia This is going to become a more plant-friendly environment throughout the Region.
It will be like starting next September, when you start self-sufficient in energy through biogas generated in the process of debugging.
The Councillor for Environment, Adela Martinez-Cachá, the Minister of Agriculture and Water, Antonio Cerda and CEO of Aguas de Murcia, José Albaladejo, today visited the construction of a biogas cogeneration plant, which involves an significant environmental improvement by reducing the energy consumption of the plant and reduce the emission of greenhouse gases into the atmosphere.
The facility has capacity to produce a volume of biogas with an energy value equivalent to about 15 Gigawatios-hora/año.
This biogas, once subjected to different conditioning processes, will be used as fuel for engines driving electrical generators.
The electrical and thermal energy obtained will be applied to the energy consumption of the own treatment or exported to the electricity distribution network, contributing to national energy efficiency.
The use of biogas generated in the WWTP may be a lowering of about more than 3,600 tons of CO2 per year, otherwise, be emitted into the atmosphere if it obtains energy from fossil fuels.
Aguas de Murcia was in charge of the works and their execution is part of the collaboration agreement signed with the Bank of Sanitation, ESAMUR, which provides a subsidy of 2.8 million euros to finance investment.
The objective of this investment is to improve the energy efficiency of the filter by utilizing the biogas produced in their own vetting.
ESAMUR estimated payback now performed within about 5 years to have to endure a lower energy cost in the operation of the sewage from the date of commencement of the use of biogas.
Currently the municipal sewage Gallego Corner is about 40 Hm3/year water and produces about 3 NHm3/año biogas, which can mean in terms of 15 GWh energy per year, of which 70% can be recovered for the production of electrical energy and heat in similar proportions.
This hypothesis could be achieved by producing the engines reduced the power consumption of the plant up to 40%.
Biogas in the Waste Treatment Centre
The facility to be built at the WWTP is the only system of its kind launched in the municipality.
Since 1999, a biogas plant at the Center for Urban Solid Waste Treatment which produces electrical energy from the extraction of methane gas generated at the landfill, specifically, from rejection and without addition of other gases.
The 3 engines allowed a production of 14,460 MW-H in 2007 and 17,335 MW-H one year later, which can achieve a saving of 15,509 tons CO2 per year.
The energy generated annually is about 40% of street lighting in the municipality, besides supplying all the needs of Treatment Center Solid Waste, helping to reduce greenhouse gases and promote sustainable development.
