Objectives
Determine the feasibility of adapting existing air conditioning duct sealant techniques to repair leaking natural gas distribution mains and network riser infrastructures with deposits only occurring at leaks requiring sealing, while producing seals that can withstand normal operating pressures for natural gas distribution systems, and with minimal service disruption. Recommendations for and progression to next stage of technology development.
Abstract
This project aims to build on the work carried out under the project entitled Seeker Particles (NIA_SGN0012).
As part of the Seeker Particles project, a number of ambitious and highly innovative technology opportunities were identified. This proposal outlines the requirements in order to take one of those innovative technologies, namely aerosol based particulate sealants, and demonstrate Proof of Concept for its use in gas pipelines and risers. It will use both experimental and numerical modelling approaches to address the key technical challenges required to bring this technology to market.

- Design and fabrication of a bench-top aerosol remote sealing test system
- Adapt the aerosol numerical model to the conditions prevalent in natural gas distribution systems and vertical risers, and validate this model.
- Assess aerosol penetration length as a function of process parameters (flow rates, particle size distribution, drying time)
- Characterise the deposition of sealant particles on interior surfaces and leak sites as a function of the distance from the injection point
- Characterize the geometry and flow conditions in low pressure sections of Scotia Gas networks
- Conduct witness testing for SGN staff and/or contractors.
