| Objectives | This project aims to develop and trial a device, based on a review of available technology, that is suitable for the detection and quantitative measurement of liquid contamination at the entry points to the NTS gas transmission system. The approach being taken is to consider using more than one detection method to give a greater chance of detecting liquid contamination. For example, vertical ultrasonics will be assessed for detecting a level of liquid, horizontal ultrasonics will be assessed for detecting aerosol liquids, multi-FID will be used to detect liquid slugs, laser technology will be assessed for detecting particular molecules, irrespective of their phase, nitrogen purging of standard analysers will be assessed to see whether this improves their performance with liquid contamination. This approach enables a range of composite detection systems to be configured for specific sites. This offers a wide range of installation options ensuring a wide range of gas quality detection capability. | |
| Abstract | Gas Safety (Management) Regulations GS(M)R regulations state that the gas " shall not contain solid or liquid material that may interfere with the integrity or operation of pipes or any gas appliance within the meaning of regulation 2(1) of the Gas Safety (Installation and Use) Regulations 1998 that a consumer could reasonably be expected to operate. "National Grid network entry conditions go slightly further and state that the gas " shall not contain solid, liquid or gaseous material that may interfere ". One of the reasons for this is that materials may be in vapour phase at the entry point, but may subsequently condense out as liquid material at some point within the downstream gas network. This project aims to provide guidance on the selection of detection & measurement equipment that could be installed at the entry points to the NTS. Gas composition is currently monitored at the entry points with "All-in- One" gas quality monitoring devices, but this is mainly provided to monitor energy content and combustion stability. In their current form, the devices have limitation in the detection of contaminants. For example, because of the high volumes of gas being transported in the NTS, it is conceivable that even small concentrations of contaminants can collect as significant volumes at points within the NTS. The devices are also simply not designed to detect some of the expected potential contaminants. The programme will be progressive development and review of the current status of suitable detection technologies culminating in the development of a prototype system. The programme will cover: Establish historic and current position with respect to liquid delivery from entry points. Identify and review techniques or currently available instrumentation suitable for detecting and/or identifying liquid contaminants within the NTS. Liaison with suppliers and specification of candidate instrumentation. Conduct laboratory trials of individual instrument components. Develop scope of further work - sourcing costs, advance discussions with external supplies, project management & presentation of findings, purchase of equipment. Develop scope for conceptual design of measurement device and analyser system. Review pipeline interface, ATEX, PED issues. Instrument build and initial instrument testing. Build of laboratory test rig and prototype testing - followed by field trials. Technical issues associated with external environmental factors interfering with the laser performance have resulted in the need for extended field trials.Note : Project Documents may be available via the ENA Smarter Networks Portal using the Website link above | |
