3D TRASAR® Technology for Boilers Improves Reliability at - Nalco

The key business drivers for the customer included:
• Improve the reliability and availability of the boiler
plant
• Maintain clean water-side surfaces in the boiler
• Reduce the volume of chemicals required for
treatment due to upset conditions
New Programme
Under traditional water treatment regimes, where
wet chemistry analyses are only conducted intermittently,
upset conditions can go undetected for
long periods, during which significant problems can
arise. This is a challenge which can be immediately
addressed with 3D TRASAR Boiler Technology,
with the patented Nalco Corrosion Stress Monitor
(NCSM). This can be extremely valuable in protecting
steam generation assets, providing real-time
on-line monitoring of system conditions, and an
immediate alarm and corrective action as soon as
upset conditions start to occur.
At the mill, Nalco and the customer worked together
to implement a joint strategy to deliver improved
boiler reliability. 3D TRASAR Boiler Technology
was installed, and from start to finish was in full
operation after just three hours of installation and
commissioning.
In keeping with standard practice, the following Key
Performance Indicators (KPIs) were established for
the use of 3D TRASAR Boiler Technology on the
boiler system:
• Ability to determine variations in corrosivity of the
feedwater and make a link to specific operational
and chemical parameters.
• Ability to control the system variability and provide
maximum asset protection and maximum
availability to generate steam for the production
process.
• Improvement in the service level by Nalco, by
providing real-time alarms and communication of
upset conditions that require immediate attention,
allowing plant operators to focus on the main
production process.
Since the unit was commissioned, it has operated
without major problems, and has required minimal
service and maintenance attention, with just one
regular service and calibration after nine months.
3D TRASAR Boiler Technology
3D TRASAR Boiler Technology is the innovative
and unique boiler treatment package, designed to
deliver superior sustainability performance, operational
efficiency, and asset protection. This groundbreaking
modular technology continuously responds
to changes in boiler operation and feedwater quality,
reducing system corrosion, ensuring clean waterside
surfaces, and minimising water and energy resource
use. The result is continuity of production, conservation
of resources, minimisation of emissions including
Greenhouse Gases (GHG), and improved cost
management.
