Description
Refinery Debottlenecking
As refinery business margins continue
to decrease, it is important to utilize the
most efficient, time-sensitive cleaning
methods available.
Most importantly, these methods
must maintain a high level of safety
considerations. Chemical cleaning fulfills
these goals.

Natural Gas Processing
Mining Decontamination
Waste Treatment
Petrochemicals
Natural gas processing comes with
challenges such as the contaminants in
equipment causing reduced throughput
and compromising product quality.
The processing of natural gas includes
removing contaminants like water vapor,
hydrogen sulfide and carbon dioxide
from incoming gas streams.
Mines that are used to access deposits
of valuable resources are susceptible to
several types of fouling.
In addition to the type of mine,
the product being mined can also
determine the type of foulants that will
appear in equipment.
Waste treatment can refer to either
municipal or industrial facilities. However,
most types of waste treatment encounter
many of the same foulants. The
equipment used to clean wastewater can
vary from sour water treating equipment
in oil refining to water hardness scale in
Dissolved Flotation (DAF) systems.
Petrochemical processing includes
cracking plants for olefin production
to linear low-density polyethylene
(LLDPE) catalytic process to alcohols
and surfactants and a multitude of other
processes. One thing they all have in
common is that process equipment
fouling is a huge problem.

APPLICATIONS
Degassing

Heat Exchanger Cleaning
Application
Description
The demand for system
decontamination which meets
or exceeds regulatory safety and
environmental requirements is growing.
Degassing reduces personnel safety
concerns and reduces the release of gas
into the environment while returning
units to full production in record time.
Eliminate dangerous elements inside
your equipment in a way that minimizes
both cost and safety risk with our
chemical decontamination strategies.
Make your equipment safe to enter
without risking safety or downtime with
chemical decontamination.
Pulling a heat exchanger for cleaning
is frustrating, time-consuming and
expensive, but we can help. We custom
engineer solutions and processes which
clean heat exchangers in place, without
the delay, frustration and expense. No
pulling equipment out of service for a
week. No hydroblasting. No
re-fabricating of bundles.

Tank Cleaning Online Cleaning Odor Control
Rail Car Cleaning
For many facilities, the conventional
tank cleaning practice is expensive
and risky. But FQE Chemicals offers a
chemical tank cleaning methodology
that’s changing the industry standard.
No crew member enters the tank, no
hazardous waste is emitted and up to
98% of your oil is recovered!
Industrial plant operation comes with
a diverse set of challenges that require
solutions tailored towards optimizing
safety and productivity. We have
developed a unique set of chemical
products designed to function in fully
operating environments to continuously
remove static foulants as well as act as
an antifoulant.
Malodors originating from processes
can negatively impact a facility due to
safety concerns, public complaints and
day-to-day operation inefficiencies. Our
odor control products rapidly remove
foul nuisance odors found in storage
vessels, wastewater and sludge. They
are designed to remove a variety of
problem odorants.
FQE Chemicals provides an innovative
rail car cleaning system that is designed
to significantly reduce cleaning
durations and waste effluent volumes
via a vapor phase injection application.
Furthermore, our process does not
require manned entry and therefore
eliminates manpower exposure to
hazardous situations.

CHEMICALS
FQE Degassing and Decontamination
Degassing is a chemical cleaning technique that reduces the hazards of dangerous gaseous
elements inside processing equipment. To improve the degassing process, it is often
recommended that decontamination (solvent circulation) precede degassing to minimize the

LEL’s from vapor spaces and equipment surfaces.
• Reduces degassing time
• Applicable for all light hydrocarbons such as
benzene, gasoline, alkylate, and para-xylene

internal combustion engines
• Can be used when venting/flaring is not
available or feasible
FQE LEL-Surface offers a perfect balance of cleaning
and LEL reduction through a patented formulation of
powerful surfactants and solvents.
• Effective in reducing LEL readings in degassing
operations

CASE HISTORY
US refinery uses FQE® Solvent-H+ to improve safety while reducing
outage time and eliminating mechanical cleaning costs
A refinery located in the Midwestern area of the United States was looking to improve upon the efficiency and
safety of their crude unit exchanger cleaning program.
Results Achieved
Summary of Case History
Over 50% Reduction in
Outage Time
Eliminated Mechanical
Cleaning Costs
Reduced Hydroblasting
Mitigates Personnel Risk
The refinery typically ran a Heavy Canadian Crude and saw consistent issues associated
with heavy organics and asphaltenes. Prior to the vapor phase application, the refinery
had utilized hydroblasting as their sole and preferred method to clean exchangers.
Due to consistent heavy fouling, these exchangers would typically take between 12
– 15 ten-hour shifts to complete. Furthermore, hydroblasting posed numerous safety
challenges associated with handling high-pressure water. These shortfalls led the
refinery to investigate pre-treatment options to reduce the hydroblasting duration
and costs.
As a test comparison, the refinery elected to compare the parallel set of exchangers;
one with no pre-treatment prior to hydroblasting and the other treated with the
patent pending FQE Solvent-H+ product. The Solvent-H+ treated bundle was vapor
phase cleaned over a 4 – 6 hour period.
Following the cleaning process, the refinery compared the two parallel sets and
found that their hydroblasting man-hours were reduced by over 50%, which made
this a significantly safer process. Furthermore, the decreased time led to over 50% in
mechanical cleaning cost savings.

• Process equipment fouling in oil refineries and petrochemical industries is an
on-going, severe and costly problem. Fouling of equipment results in costly
operational problems that include:
• Reduced reliability and processing flexibility;
• Inefficient heat transfer and subsequent increases in energy costs;
• Excessive maintenance requirements;
• Potential safety and environmental concerns
• Equipment damage;
• Reduced throughput.
• Exchanger Cleaning with FQE® Solvent-H
• FQE Solvent-H dissolves fouling deposits in process equipment and restores
system efficiency. This yields two very important results: it lowers disposal costs
and eliminates the need for personnel entry into a confined space, which results
in a much safer cleaning process.

Chemicals Utilized
A large Canadian oil sands operator utilized FQE®
Solvent-H, FQE® LEL-V, and FQE® H 2 S to clean a
large primary separation settler in record time.
The product in the vessel was made up of mostly solvent (C5/C6), and bitumen.
The vessel had a top cylindrical section with an internal diameter of 15.2 meters,
and a conical bottom section with a 60° angle. The settler was enclosed by a
hemispherical roof to contain the vapors released from the froth and solvent
mixture. The previous attempt by a competitor to clean the settler left LEL
present due to the solvent that was trapped in the asphaltene buildup in the
cone of the vessel.
FQE Solvent-H was applied first to dissolve and flush away heavy deposits at
the bottom of the vessel. Afterward, FQE LEL-V and FQE H 2 S were applied to
remove LEL and H 2 S respectively. The whole operation was done in record time
with a minimum deposit residue at the bottom.

• Health Effects of NORM
• Even with low dose exposure, cellular damage is cumulative and the effects of
repeated exposure may not be realized for many years. For this reason, refiners
have understood the importance of radiation accumulation control.
• Standard Cleaning Practice
• Standard industry practices include abandoning equipment or high pressure
water blasting. Both options result in a large expense to the owner.
• NORM Decontamination with FQE® NORM-Clear and FQE NORM-Precip
• FQE NORM-Clear and FQE NORM-Precip have been designed to address these
highly challenging difficulties and to focus on efficient Radium removal through
selective extraction and preferential adsorptive fractional precipitation. These
techniques effectively target Radium for expedient and cost effective control of
NORM scales and contaminated waters.
