Gas Leak Detection for Downstream Oil & Gas

Help refineries and petrochemical plants avoid unplanned downtime and accelerate turnarounds — with acoustic cameras that find any gas leak, any time.

Downstream operations: maximizing uptime, minimizing unplanned shutdowns

Refineries and petrochemical plants run complex, continuous processes where an undetected gas leak can trigger an unplanned shutdown, compromise worker safety, or result in a regulatory violation. Scheduled turnarounds — driven by legal, technical, and economic requirements — demand comprehensive tightness testing that must be completed on tight timelines.

Distran acoustic cameras support downstream teams across the full operational lifecycle: from commissioning new units to LDAR surveys during normal operations, and tightness testing during turnarounds. A single device detects leaks of air, nitrogen, methane, hydrogen, acetylene, and any other pressurized gas — giving teams one reliable tool for every phase.

Inspect thousands of flanges in hours rather than days. Acoustic cameras cover large areas from the ground — no scaffolding, no lifts — and locate leaks remotely at up to 100 m.

Operators remain at a safe distance from pressurized systems and hazardous gases throughout the inspection. ATEX/IECEx certified for use in explosive atmospheres.

Methane, hydrogen, nitrogen, acetylene, compressed air, and vacuum leaks — all detectable with one device. Unlike OGI cameras, acoustic cameras work on inert gases used during tightness testing.

Systematic leak surveys with quantified leak rates enable compliance with LDAR requirements and help meet fugitive emission reduction targets under EU and national regulations.

Audalytics captures leak rate data, images, and video for every leak found — enabling structured reports, asset tracking, and repair prioritization over time.

No specialist training required. Teams are operational after a short introduction — any maintenance or HSE technician can run a survey.

TotalEnergies Feyzin — Zero Tolerance for Leaks

The TotalEnergies Feyzin refinery, one of France's most critical industrial sites, processes 5 million tons of crude oil annually. During scheduled shutdowns — involving up to 100 people over 5 weeks — every flange, valve, and pipe joint must be verified leak-free before restart, including the ~1,300 flanges in the Alkylation unit alone.

The team replaced soap spray with the Distran Ultra Pro X. Operators now locate leaks from 30–40 m away without scaffolding, inspect complex units from the ground, and consistently meet the site's strict "zero leaks" requirement before every restart. 300 operators are trained and cameras are available 24/7 in control rooms across the platform.

"Inspections are carried out remotely, easily, quickly, and, above all, safely. The Ultra Pro X has become an indispensable tool — it is constantly in use in the various units." — Vincent Leleux, Deputy Head of Operations, TotalEnergies Feyzin

Arkema — Inspection Time Cut from Days to Hours

At Arkema's specialty chemicals facility, gas leak inspection during maintenance campaigns traditionally required days of manual work. Complex piping networks and thousands of potential leak points made full coverage slow and resource-intensive — with a real risk of missing leaks in hard-to-reach locations.

After deploying the Distran Ultra Pro, the team completed the same inspections in a fraction of the time. A single operator covered large areas rapidly, detecting leaks that conventional methods had missed — and generating the documentation needed to prioritize and track repairs.
