ABOUT THE PROJECT

Pietro FiorentiniTerranova and Reti Più are partners in the Life+ 2013 Project called “Life Green Gas Network” (Project n. LIFE13 ENV/IT/000536), EU financial instrument that supports environmental action projects aimed to preserve the nature and the climate throughout the European Union.

The project aims to demonstrate the possibility of implementing a new management and control system for the adjustment of pressure levels of the natural gas distribution network.

The main core of the project is the implementation a new remote communications management software between network and control center, together with a real time data processing, in order to optimize the pressure in each sector of the network. This system aims to reduce at least by 3% the greenhouse gas emissions caused by the gas leakages.

WHAT IS THE PURPOSE OF LIFE GREEN GAS NETWORK PROJECT?

The natural gas distribution networks may experience gas leakages near old junction points between tubes and valves that are parts of the distribution system, or as a consequence of damages such as excavations or vehicle collisions: these losses are directly proportional to the pressure at which the gas is kept in order to ensure the proper quality of service standards.
How can we balance the two apparently opposed needs, minimizing the leakages caused by damages and maximizing the quality standards offered to the users?
The answer to this question lies in the development of new technologies that allowto reach the right balance between these needs, when  successfully implemented.
The "Life Green Gas Network" project aims to demonstrate the feasibility of a new management and control system for the pressure levels regulation in the natural gas distribution network. In order to reach this purpose, the project involves the development, the test and the actual implementation of a new software for the management of remote communications between network and control center. Furthermore, real time data processing allows the real time pressure optimization in each network’s sector.

Thanks to this system, our team forecasts that the greenhouse gas emissions caused by the abovementioned gas leakages should decrease by at least 3%.

WHAT ARE THE EXPECTED RESULTS?

With reference to the purposes that the project aims to reach once the system will be active and operating, these will be expected results of the project:

1.    Significantly lower pressure values during off-peak hours on the network test areas (Albiate and Cesate Municipalities), once the new automatic pressure regulation system will be online for low (BP) and medium pressure (MP) and for all types of pipes, steel or polyethylene (PE ), as shown below:

  • Albiate, MP, steel: 1 bar instead of 2 bar
  • Albiate, MP, PE: 0,5 bar instead of 0,9 bar
  • Albiate, MP, steel and PE: 20 mbar instead of 24 mbar
  • Cesate, MP, steel and PE: 1.5 bar instead of 2.5 bar
  • Cesate, LP, steel and PE: 25 mbar instead of 40 mbar

With these values a reduction of at least 3% of the gas leakages will be obtained, and, consequently, a reduction of the GHG emissions. The total amount of gas saved in the network’s section involved in the test phase will consist of 467 CO2 TEQ;

2.    In relation to the service levels, the goal is to maintain a pressure level for all the delivery points of the network section involved in the test of 18 mbar or higher. With reference to the network’s balancing, the goal is not recording significant variations of speed and/or flow inversions in any of the pipes belonging to the network’s test area;

3.    The new system must ensure the safety standards requested by the ATEX legislation, it has to be self-powered with no connections to the electric grid in case the latest is not already available and, from a performance point of view, it must be able to allow at least a pressure modulation procedure per minute on all the pressure regulators;

Dissemination activities have to reach the following purposes: publication of articles on at least 2 different publications about gas and participation in 4 events (exhibitions and seminars) in Europe and in Italy, involving at least 2.000 people.
