National Grid improves detection of contamination in gas supplies


LineVu installed at the entry point

National Grid has released the report on a 32-month project evaluating Process Vision’s LineVu system.

Safety is our primary consideration.

UNITED KINGDOM, August 5, 2021 / – Contamination of gas networks is a global problem, causing corrosion and damage to installations and equipment with high cleaning costs. The project validated improvements in the detection of contamination entering gas networks and demonstrated that LineVu is ready to move from research to normal operating equipment with plans to install systems at gas entry points. UK transport network.

LineVu brings a new approach to surveillance. It is a permanently installed camera-based system, using image processing to provide an alarm when contamination is detected, and provides access to a live video feed of pipeline activity. . The implementation of this technology will allow operators to make proactive and evidence-based decisions.

More efficient maintenance will be possible and the threats posed by contamination will be considerably reduced.

It is known that liquid events can greatly increase the uncertainty of tax measures, such as debit and
Calorific value. Limiting these events and the knowledge gained from monitoring can reduce these errors.

Capable of detecting all types of solid and liquid contamination, LineVu provides pipeline operators with certainty about pipeline contamination levels. During the National Grid project, LineVu technology provided good levels of validation using a variety of flow regimes.

The Gas Safety (Management) Regulations (GS (M) R) require that gas transported in the national transmission system does not contain liquids or solids. The project raises awareness of the contamination of gas streams received in the network and the industry’s dependence on the efficiency of separators.

LineVu technology draws attention to separators and compressors that require maintenance.

A live video feed directly to the control rooms allows operators to react to alarms immediately in the same way they would if the gas did not meet specifications for water vapor or H2S.

• lead to better compliance with GS (M) R;
• improve flow assurance;
• reduce operational risk;
• lead to better maintenance of asset integrity;
• act as an early warning to avoid damaging the plant
and instrumentation.
