Water Monitoring
and Removal is Critical for All Storage and
lubricating systems . Poor operations and
maintenance procedures for water monitoring
and removal from storage systems can lead
to a number of problems, from degradation
of fuel or oil quality and subsequent decrease
in performance or breakdown of major equipment,
microbial contamination and capital losses.
This pertains to all storage systems, both
underground and aboveground and all lubricating
and hydraulic systems constructed of any material
and storing/moving nearly any oil based product
- gasoline, diesel, lube oil, heating oils,
aviation jet fuel and others.
Entire systems
are potentially impacted by water and its
possible consequences. It is impossible to
live without a water problem and even worse
not to continually monitor the extent of water
contamination. It is imperative that all owners
and operators of oil storage systems immediately
implement routine and regular operations and
maintenance procedures for water monitoring
and removal of water and even better to install
online water monitoring devices. |
The EASZ-1 is an online sensor easily retrofitted
to any oil purification or filtration system
to ascertain the moisture contamination level
and the effectiveness of the purifier or water
removal system. Normally the EASZ-1 is a same
day ship item, it has a analog output corresponding
to water content which can be plugged into
a control system. PLC or remote display.alarm.
Recent Industry
Changes Elevate the Importance of Water Monitoring
and Removal Although operations and maintenance
procedures for water monitoring and removal
have been a recommended practice for over
thirty years, recent changes within the industry
have increased the risk for water entry and
accumulation in the storage system, and subsequent
microbial growth if water is not removed.
The distribution infrastructure has seen a
lot of changes. More fuel is moving faster
through the distribution/delivery infrastructure,
leaving less time for water to settle out
before the product moves from step to step
in the distribution process. |

A shift from proprietary to shared delivery infrastructures
(bulk terminals, pipelines, transports) has removed
much of the control that individual companies had
over the process and product. From the removal of
lead and MTBE, to additives such as ethanol and
biodiesel, product chemistry has undergone fairly
recent change. These new fuels are more susceptible
to moisture accumulation, separation and potential
biodegradation accelerated by water. For example,
lead was a natural poison to the microbes that could
grow in a moist environment - in today's lead-free
fuels, microbial growth can more readily occur.
Installation procedures.
Common procedures - including
open vents, low fill areas and sloped tank installations
- contribute to water accumulation. Microbial activity
is better understood and more common. As a result
of the above changes within the industry, microbial
activity has been found to be a much more common
phenomenon than previously realized. If you are
in the fuel business -In order to safeguard your
business, maintain good customer relations, ensure
high-quality fuel, and leak-free operation of your
storage systems, you must monitor for water in those
systems and remove water whenever it is detected.
This must be a routine part of your operations and
maintenance procedures. |
Water can enter a system in many ways
via damaged fill boxes or fill cap gaskets, loose
fittings or plugs, poor practices relating to spill
buckets, rainwater accumulated within tank sumps
and which enter via any tank orifices that are not
water/vapor tight, and condensation caused by oil
temperature swings or air entering via vents, leaks
in seals and so on.
Certain oils and fuels are also
more prone to moisture attraction and subsequent
separation when subject to temperature swings. Preventing
Potential Problems Associated with Water Major industry
groups have developed recommended operations and
maintenance procedures, but best practices should
include monitoring and checking for water with online
water monitors. |

Inspecting fill and vapor caps for
damages and for missing gaskets, replacing if necessary.
Inspecting product and spill containment buckets
and proper disposal of water if found (not draining
back into the tank).Auditing the fuel delivery process
and water content. Using water-sensitive fuel filters
and watching for slowed-down fueling.
Treating storage
tanks with antimicrobial pesticide (biocide) on
a regular basis ,employing a qualified professional
to examine the inside of the tank and system and
taking samples from process systems and many other
practices can be employed but in the end we need
to know the effectiveness of these practices. An
online water sensor takes away the guessing in this
all.
Hazy or waxy fuel samples indicate water and
readily available field detection kits can check
for microbes and whether the fuel meets specifications.
|
If water is detected at any time, it must be removed
by qualified service contractors. Signs of Microbial
Growth Plugged fuel filters are a common result
of microbial growth, caused by the slime created
by a thriving microorganism colony clogging the
small filter openings. Filter life shorter than
six months is a warning signal .Other signs are
plugged lines, erratic gauge readings, frequent
replacement of other components such as valves,
rubber seals and hoses. Problems may also surface
in machinery fueled or lubricated by contaminated
product,. Field detection kits can verify water
on a spot sample basis, microbial growth, particles
and other parameters but poor operations and maintenance
procedures for water monitoring and removal from
systems can lead to a number of problems. Without
realtime knowledge of the water contamination
the oil quality can be degraded and result in
poor performance or even damage.
Filters can become prematurely plugged and lead
to excessive maintenance and replacement costs.
Users become dissatisfied and money can be lost.Microscopic
bacteria can grow in a moist environment and attack
the entire system, including steel process lines
and tanks, tank linings, elastomeric seals and
hoses, low points in the piping, leak detectors,
turbine pump components, filters and valves, including
overfill prevention devices. •In the worst
case, product leaks can cause environmental damage,
leading to costly cleanup and facility downtime/lost
business. Online water monitoring and good maintenance
procedures for water monitoring and removal should
be implemented for oil systems. Nearly all stored
products can be adversely affected by the presence
of water. An extreme example is aviation jet fuel,
where water in the product has obvious harmful
consequences. But even heating oil systems are
subject to problems caused by water. The presence
of water in fuel oil can cause oxidation, a natural
chemical process that breaks down the fuel oil
and forms insoluble particulates, commonly called
"sludge". This sediment can clog fuel
lines, nozzles, filters and screens - and ultimately
lead to wear in pumps and system malfunction.
