Description
This case study describes different solutions deployed by GRTgaz to reduce venting on its transmission network, to recover or reduce pipeline maintenance vents, compressors vents and even smaller vents on delivery stations. During maintenance works on transmission pipelines, a mix of solutions enabled GRTgaz to save more than 90% of the gas that would otherwise have been vented since 2018. On compression stations, a specifically-designed mobile recompression technology addresses intermediate-sized volumes. In addition, when recovery is not yet possible, a mobile blue flare stack is used to address vents. GRTgaz also implemented a specific multi-year investment plan to eliminate vent leaks and use gas resulting from depressurizations.
