In 2016, programmes for upgrading turbines at the stations were continued. In particular, turbines were put into service at the Poggio Renatico (TC4) and Messina (TC3) plants
The indicator that takes into account the NOx emissions on the energy used fell by 10%
NOx emissions into the atmosphere are determined based on direct measurements or, if these are not available, on emission factors present in the relevant literature (the EMEP/EEA Air Pollutant Emission Inventory Guidebook of the European Environment Agency)
Nitrogen oxide emissions (NOx) derive from the gas turbines in the compressor stations (compression and storage) and the vaporisers at the liquefied natural gas regasification plant. In 2016, total nitrogen oxide emissions were around 434 tonnes (+8.4% compared with 2016), while the indicator that takes into account the emissions for energy used fell by 10% thanks to the ever-increasing use of DLE turbines, which were used for 88% of operational hours in storage and 94% in gas transportation. The use of natural gas as its main energy source allows Snam to minimise emissions of sulphur oxides and particulate matter.
In order to reduce nitrogen oxide emissions deriving from the combustion of natural gas in the gas turbines used in compression stations, in recent years a number of existing turbines were modified and new units installed with dry low emission combustion systems, while at the regasification plant, submerged flame vaporisers were installed.
In 2016, the DLE turbocompressors were put into service at the Poggio Renatico (TC4) and Messina (TC3) plants.
Total NOX Emission (t)
NOX emission / energy consumption
NOX atmospheric emissions are determined based on direct measurements or, where these are not available, on emission factors present in the relevant literature (the EMEP/EEA “Air Pollutant Emission Inventory Guidebook”).
