Introduction: The scope of this project includes:

• MEG saturation monitoring capability required to accurately gauge fogging performance

• Enabling indirect as well as direct fogging including designing, building and installing an indirect system and then testing performance and flow through the indirect route.

The scope of this project does not include the MEG Fogger development and certification, which will be carried out under a separate phase.

Objectives:

The overall aim of the MEG Improvement initiative is to design, develop, manufacture, install and commission a TouchSpray MEG Fogging system for use on the National Grid Gas Distribution network, in order to achieve a major improvement in MEG saturation levels across the network.

The objective of this project, under Phase 2C, is to enhance the TTP air based facility built as part of Phase 2B ahead of droplet size testing occurring.

Expected Benefits: The success of this project will be learning regarding the analysis and development of deployment methods to optimize MEG saturation to take forward into the TouchSpray MEG Fogger trial. This information will inform the overall  initiative of improving MEG  saturation levels across the gas distribution network.
