Background
• Traditional LDAR
– EPA Method 21
– Expensive and labor intensive
– $250,000 - $1,000,000 per year per facility (depending on component
count)
– Certain components are not covered
– Complicated program and tedious field work
• Smart LDAR
– Optical gas imaging (IR cameras)
– Lower cost
– EPA promulgated Alternative Work Practice (AWP) rule in Dec.
2008
– Adoption of AWP is severely limited because the AWP rule requires
Method 21 once every 3 quarters
Background
• Next generation – LDAR3
– Proposed by Providence in 2006
– Unattended IR cameras with computer vision algorithm
capable of recognizing plume
– Fugitive emissions from leaks are a function of detection
limit and frequency of inspections
– Increased monitoring frequency allows early leak
detection, resulting in equal or better environmental
performance even at a higher leak definition
– Coverage for non-traditional LDAR components
Background
• A technical analysis – Monte Carlo Simulation
Enabling Technology
• Advancements in optical gas imaging have made LDAR3
feasible
– Autonomous leak detection algorithms – The core
enabler
– ExxonMobil/Providence InteliRedTM
– Other enabling/enhancing techniques:
– Industrial enclosures for continuous operation in harsh
environments
– Higher resolution imagers
– Better optics, continuous zoom, longer focal lengths
– Extended lifetime coolers
– Remote camera/gimbal/lens control
Autonomous Leak Detection Algorithm
• IntelliRedTM jointly developed by ExxonMobil and
Providence
• Autonomous remote gas plume detection
• Computer vision algorithm applied to infrared (IR)
video for continuous surveillance
• Industrial alarming interface (Modbus/TCP)
• Real-time streaming video enhancement
• The core enabling technology for LDAR3
Autonomous Leak Detection Algorithm
• Autonomous detection of 2.5 lb/hr Propane leak at 260 feet
Autonomous Detection Algorithm
• Autonomous detection of 1.25 lb/hr Propane leak at 220 feet
Autonomous Detection Algorithm
• Autonomous detection of large Natural Gas plume at 1200 feet

container prop
• Two leak points, each 4 lb/hour
• Camera located 215 feet from leak source
• Winds calm and variable
• Temperature 85F, early afternoon

Comparison with Smart LDAR
Smart LDAR
• Conditions at the time of
inspection may hinder
detection of a leak –
missed detection for 4-6
months on bi-monthly or
quarterly schedule
• Periodical inspection – a
leak may be undetected
for 2-3 months
• Manual inspection, high
operating cost, prone to
errors
LDAR3
• Continuous detection – a
missed detection in one
moment will be detected
in a later moment when
the conditions become
favorable
• Continuous detection –
leak detected in near real
time
• Higher initial capital cost;
much less operating cost

Summary/Conclusions
• Advancements in technology make LDAR3
technically feasible
• The InteliRedTM technology is now commercially
available
• Cost savings vs. Method 21 and Smart LDAR
make LDAR3 economically feasible
• For environmental compliance, changes in
regulations will be required – ideally incorporated
in the Uniform Standard
• For non-regulatory applications (e.g., process
safety, proactive leak reduction for better LDAR
results), the InteliRedTM technology is ready NOW
