Socrate ERS
Innovative Solution for Reducing Emissions from Chromatographic Systems
Socrate Spa’s patented ERS system reduces continuous methane (CH4) emissions in natural gas quality measurement systems by up to 90%, complying with EU regulations 2021/0423. Thanks to a logic synchronized with the chromatograph, the ERS system optimizes sample use and limits discharges, contributing to environmental sustainability in measurement and compression stations.
The ERS Pat. Pend. System has been designed to reduce the intensity of continuous emission sources deriving from intrinsic leaks in natural gas quality measurement systems, in order to reduce total CH4 emissions in accordance with the proposed EU regulation 2021/0423 (COD) issued by the European Commission. Most natural gas and biomethane measuring stations are equipped with a gas quality monitoring system based on chromatographic technology, which for application reasons requires a continuous fast loop to ensure that a fresh and representative sample is available to the chromatograph at the time of injection.
This volume is vented to the atmosphere as a flaring system is almost never available. Given the environmental impact of methane (CH4), which is much higher than that of CO2, Socrate S.p.A. has developed a dedicated system to reduce continuous emissions from the chromatographic system by up to 90% and more. This system accounts for the majority of fugitive emissions from measuring, compression, and reduction stations throughout the national network.

Operation
Given the cyclical nature of chromatography, using a logic unit synchronized with the chromatograph and a flow interruption unit, the ERS Pat. Pend. interrupts the sample flow towards the vent (both on the chromatograph side and on the fast loop side) for the time during which the sample does not need to flow, activating these flow rates only for a programmable period of time calculated on the basis of the necessary advances imposed by the geometry of the system.
