Devcon® Epoxy Coat™ 7000 AR Protects Petrochemical
Containment Area from Chemical Corrosion
Petrochemical manufacturing involves the refinement of crude oil to
yield ethane, butane, and propane. However, before this crucial step,
crude oil must be washed of its naturally occurring contaminants, to
ensure a high-quality output.
One of the most common ways these contaminants are removed is
through addition of sulphuric acid to crude oil. Sulphuric acid is a
highly corrosive chemical, which (if not handled properly) can cause
safety hazards and put an abrupt stop to plant operations. To
prevent a safety emergency, secondary containment areas are
installed around the equipment to avoid acid leaks and spills.
Problem:
At a petrochemical plant, the structural integrity of a concrete
secondary containment area was threatened by sulphuric acid
equipment leaks. This secondary containment area was previously
coated with an epoxy that was unable to withstand frequent exposure
to corrosive chemicals.
Due to frequent damage to the secondary containment area, the old
coating had to be reapplied repeatedly which was expensive, time
consuming, and unsafe for employees. This client was in need of an
industrial strength epoxy coating that would withstand consistent
chemical exposure, limiting time spent on maintenance repairs.
Solution:
Devcon Epoxy Concrete Sealer and Devcon Epoxy Coat
7000 AR was selected due to its ability to withstand severe
acid and chemical attack.
• The secondary containment area was primed and the surface area
sandblasted to ensure optimal adhesion of Devcon coatings.
• The flooring was then chemically cleaned to remove all traces of
contaminants and neutralize the acidic environment.
• Devcon Epoxy Concrete Sealer was first applied to create a seal to
prevent chemicals from degrading the concrete.
• Devcon Epoxy Coat 7000 AR was then applied to provide the
required adhesion and resistance to highly concentrated sulphuric
acid.

Project Outcome:
Highly Durable Coating
Devcon Epoxy Coat 7000 AR is resistant to sulphuric acid in concentrations
up to 98% proving its ability to withstand the corrosive nature of the
petrochemical manufacturing process. In conjunction with Devcon Epoxy
Concrete Sealer, Devcon Epoxy Coat 7000 AR prolongs the life of the
secondary containment unit providing a safe, durable solution for this
petrochemical plant.
Easy Application in Difficult Environments
Many times, secondary containment systems can cover an extensive amount
of area to surround large industrial equipment. Devcon Epoxy Coat 7000 AR
can be seamlessly applied via squeegee and brush roller, to large horizontal
and vertical surfaces.
Lowers Repair Costs
A low-grade coating that requires frequent replacement is a short-term
solution driving up maintenance repair costs at this petrochemical plant. With
Devcon Epoxy Coat 7000 AR this industrial strength epoxy coating is a highly
durable solution lowering maintenance costs in the long run by limiting the
amount of time spent on repairs.
