Objectives The objectives of the project Design and manufacture a prototype spray head that can be retro fitted to current MEG fogger units. Successful lifetime testing and CE mark certification prior to installation A demonstrated increase in MEG saturation levels as result of the operation of the new fogger head technology. Demonstrated and documented increase in saturation levels as a result of the installation of the ne fogger head units. A reliable prototype unit capable of being produced to be installed on the network.
Abstract The introduction of dry natural gas in the 1970s caused the yarn in these joints to dry out, creating leakage paths. For many years, National Grid has replaced the lost moisture by operating gas conditioning plant, which injects mono-ethylene-glycol (MEG) into the gas stream at selected system source points chosen because of high levels of lead yarn joints downstream. The MEG is adsorbed by the yarn causing it to swell and re-seal the leak path. The spray head design developed in previous phase will be modified to be fitted to existing MEG Fogger units. Prototype units will be manufactured and fitted in four trial sites and monitored for a year. A final report will be produced to document the technologies effectiveness.Note : Project Documents may be available via the ENA Smarter Networks Portal using the Website link above
