Haydale says that one of its composite transmission piece (CTPs) has been installed at one of the UK’s National Grid’s 24 compression sites, as part of a project to meet tighter emissions control limits. Other CTPs are in the process of being fitted at additional compression sites, the company said.
Because the National Grid’s gas compression facilities have to comply with the Integrated Pollution Prevention and Control (IPPC) directive, the compression sites have been identified as requiring upgrade to meet tighter emission control limits, Haydale says.
’National Grid has a number of compressors around the country that work as ‘pumps’ to move gas around the national gas transmission network,’ said Paul Ogden, senior civil engineer at National Grid. ‘Some of the older compressors are driven by gas powered turbines, which need changing to modern low emission electric drive units. To keep the compressor sites constantly operational, new pipeline arrangements were needed, involving construction of 900mm diameter pipelines passing through new reinforced concrete walls, and the introduction of new glass fiber reinforced plastic (GRP) transition wall units.’
