Dry gas seals usually are labyrinth
seals where the gap between static and
rotating components is around five microns.
In every failure, contaminated gas
allowed liquids to get between the faces
of the seal. The gap should be controlled
by gas pressure, but when liquids or
solids are present, they create a bridge
across it that conducts heat and allows
the two parts to touch. This contact accelerates
wear, shortening the life of the
seal significantly and, in some cases,
causing a loss of containment.
We may never be able to eliminate
the risk of liquids contamination, but we
can do far better. By installing process
cameras on pipelines and using machine
learning to turn the feed into digestible
metrics, engineers can quickly identify
when mist or stratified flows make it past
separators, then take steps to remediate
the situation. This practice will:
· Reduce gas processing plants'
downtime;
· Enable greater NGL recoveries;
· Improve fiscal measurements' accuracy;
and
· Shrink compressor service costs.
These benefits frequently justify process
cameras' costs even before considering
how much they improve safety.
❒
Editor's Note: This article is based
on " See What's Happening in Your
Pipeline: The Future of Gas Plant Management, "
a white paper presented at the
GPA Midstream Technical Conference,
which was held April 3-6 in Plano Tx.
The paper includes more examples of
camera data and discusses liquid carryover's
implications for transmission
pipeline operators.
PAUL
STOCKWELL
Paul Stockwell is the founder and managing director of Process Vision Ltd., which provides
cameras that act as permanent monitors for gas/liquid separator efficiency. He has 35 years of
experience working in oil and gas systems and a long history of focusing on moisture
measurement. In addition to founding International Moisture Analysers in 1991, he served on
working parties for the United Kingdom's National Physical Laboratory to improve liquids
measurement in dry gas. Stockwell also helped develop the first tunable diode laser system,
which has become the industry-standard method for measuring moisture in natural gas. He is
named inventor on 16 granted patents and has 22 pending patents.
