Hydrocarbon Processing - October 2021 - GP-10
INDUSTRY FOCUS: PIPELINES
U.S. President Biden also issued an executive
order in May 2021 directing federal
agencies to incorporate the economic
risks from climate change into decisionmaking.
Although this does not specifically
address fossil fuel investments, the
concern among energy producers is that
financial regulators will ultimately use
their power to steer banks and investors
away from the industry.
This raft of national and international
legislation is setting a very high bar for
the natural gas industry, not just in the
U.S., but around the world. The problem
is that the scale of operations that must
be addressed is immense. The 3 MM mi
of pipelines in the U.S. alone-some of
it in incredibly remote areas-present a
massive undertaking for reactive maintenance,
let alone proactive.
Mobile gas leak detection technologies-both
portable and vehicle-mounted-do
exist, and are ideal for easierto-access
locations. However, when the
hostile and sometimes near impenetrable
or inaccessible nature of some locations
is considered, even the most rugged 4×4
vehicle will have issues.
Aware of this impending legislation
and the ethical, financial, societal and
political turmoil behind it, development
work has been put in motion to enhance
sensor technology and, more importantly,
make it far more portable.
Drone technology is the answer.
Thanks to significant advances in sensor
technology, especially those relating to
cavity enhanced laser absorption spectroscopy
techniques, methane can now be detected
with a sensitivity more than 1,000
times higher and over 10 times faster than
conventional leak-detection tools. More
importantly, this technology is not only
sensitive and fast, but also small enough
to be mounted on commercial drones.
The author's company has released a
new technologya
that can be mounted on
low-cost commercial UAVs capable of carrying
3 kg (6.6 lb) payloads (FIG. 1). Flying
at altitudes of 40 m (130 ft), or higher,
and at speeds up to 88 km/hr (55 mph),
the drone-mounted solutiona
can detect,
quantify and map leaks up to 100 m (328
ft) from natural gas distribution and transmission
pipelines, gathering lines, storage
facilities and other potential methane
emissions sources.
Previous leak-detection efforts relied on
slow, qualitative, analog sensors or expensive
delicate cameras to find leaks, but the
extremely fast response and high precision
of the new analyzer technology (FIG. 2) allows
scientists and researchers to reliably
quantify greenhouse gas fluxes, which provides
important information when studying
the complex environmental processes
affecting climate and pollution.
This new drone-based systema
has become
available at the ideal time for pipeline
operators. Based on the stipulations
in the PIPES Act of 2020, operators can
now update maintenance plans with the
knowledge that the technology is available
to make remote leak detection a far

simpler and cost-effective proposition.
These advances in sensor technology are
not restricted to drones-they can also be
easily deployed in vehicles and handheld
monitoring systems, providing a defensein-depth
approach to detect, map and
quantify large, small and even hidden leaks
with unprecedented speed, reliability and
accuracy throughout the entire natural gas
infrastructure, including upstream, midstream,
downstream and gas utilities. GP
