CASE STUDY
Green chemical cleaning of plate heat exchangers at a Oil
Refinery in the Middle East.
The Challenge
A large refining company in the Middle East used
bCLEAN.CIP to chemically clean and dissolve sea
shells and barnacles stuck in the sea water side of
21, 5m3 capacity Plate Heat Exchangers.
Results Achieved
VSM was approached by a large Oil & Gas service provider and chemical
cleaning company that was awarded a PHE cleaning contract for 21 plate
heat exchangers by one of the largest petroleum refining company in the
Middle East.
To perform CIP and remove sea
shells and barnacles stuck inside
the plate heat exchangers without
opening the PHE’s or physical
cleaning.

Sea Shells and barnacles
dissolved in less than 12
hour CIP cycle.

More than $1M savings in

physical cleaning of 21 PHE’s
Reduction in downtime with
considerable operational &
maintenance savings.
Products Used
bCLEAN-CIP
Green, biodegradable low foam CIP
cleaner, descale, degreaser for heat
exchangers, boilers, cooling towers,
amine systems, clogged pipes,
industrial cleaning. Replaces toxic
mineral acids. Non-corrosive,
nontoxic.
Conventional cleaning with mineral acids were used to perform the
cleaning but failed as sea shells and barnacles were found stuck between
the plates.
VSM requested for samples of the scaling, sea shells and barnacles and
customized bCLEAN.CIP to perform the cleaning and dissolving of the sea
shells and barnacles without physically opening the PHE’s. 5000 liters of
bCLEAN.CIP was set in each PHE for 8 hours for saturation and then
circulated on both sides of the PHE’s, cold and sea water for another 8
hours with pH correction checks every 60 minutes. This process
completely descaled, dissolved the sea shells, barnacles and restored the
PHE’s for normal operation after clean water flushing.
.sc
NO HAZARDOUS MINERAL ACIDS WERE USED. The refinery
confirmed that bCLEAN.CIP chemical could dissolve 96.5% of the
shells and barnacles and around 78.4%wt of the small particles in 6
hours of treatment time and the spend liquid was not hazardous for
disposal.
