Abstract

Based on previous work, ROSEN Engineers believe the quantity of natural gas vented during commissioning operations can safely be reduced, by up to 80%, through targeted changes to direct purging procedures.

For Gas Distribution Networks’ (GDNs), gas venting remains a necessary part of normal operations for maintenance or safety purposes. Previous research work undertaken by ROSEN(UK) Limited for the EIC, with project partners Northern Gas Networks (NGN) and Wales and West Utilities (WWU), identified activities where venting of natural gas to atmosphere occurs (Gas Venting Research Project, NIA reference number NIA_NGN_282)

The project will deliver new learnings around the duration required to purge newly commissioned gas mains and services across the full range of expected pipe diameters and pressures. This has the potential to make GDN’s commissioning operations quicker as well as reducing emissions associated with the commissioning process.
