3D TRASAR Boiler Technology

Excellent control of boiler water chemistry is essential to the energy efficiency and integrity of steam and heat generating systems. Poor management of heat transfer surfaces and water use can have major impacts on systems performance and integrity.

3D TRASAR Boiler Technology is the innovative and unique boiler treatment package designed to deliver superior sustainability performance, operational efficiency and asset protection. This ground breaking technology continuously responds to changes in boiler operation and feed-water quality, reducing system corrosion, ensuring clean waterside surfaces and minimising water and energy resource use.

eROI Case Studies

eROI, environmental Return on Investment, is how Nalco reports sustainability perfomance and operational savings to customers.  Below you will find several examples of how 3D TRASAR Boiler Technology has helped Nalco customers improve their boiler water operations and environmental footprint.


A petrochemical refinery was suffering tube failures on it's steam generating plant resulting in poor asset availability. 

Plant: Refinery
Background: Steam generation
Situation: Tube failures on steam generators are resulting in poor reliability
Application: 3D TRASAR Boiler Technology
Benefits:
  • Reduced boiler blowdown by improvement of
    feedwater quality and boiler concentration cycles
  • Improved energy efficiency
eROI:
  • Reduced make-up water usage of 47,300 m3/yr
  • Reduced CO2 emissions of 3,000 tonnes/yr
Economic Results:
  • Reduced energy usage of Euro 248,000 per year
  • Reduced water usage of Euro 53,000 per year
More Information: Case Study CH-941E

A European food factory was experiencing steam contamination due to boiler water carryover and increased corrosion due to intermittent operation.

Plant: Dairy
Region: Europe
Background: Steam generation
Situation:
  • Steam contamination by boiler water carry-over
  • On-off operation of the boiler caused poor deaeration upon start-up, leading to increased
    corrosivity
Application: 3D TRASAR Boiler Technology
eROI:
  • Improved steam quality and purity
  • Real time detection of upset to prompt changes
    in boiler operation
  • Improved system reliability

Case Study CH-997E

A European power generator wanted to minimise the risk of damage from Flow Accelerated Corrosion (FAC) in their combined cycle plant.

Plant: Power Generator
Region: Europe
Background: Steam generation
Situation: The station wanted to improve their diagnostic and monitoring capabilities to identify and minimise conditions that can lead to Flow Accelerated Corrosion (FAC)
Application: 3D TRASAR Boiler Technology
eROI:
  • Increased energy efficiency
  • Improved system reliability
  • Better cost management
  • Improved worker safety
Economic Results:

Est. Euro 2,000,000 per unit in repairs and potential loss of revenue
More Information: Technical Article R-983E

A European pulp mill was suffering from process contamination of the boiler system.

Plant: Pulp Mill
Region: Europe
Background: Steam generation
Situation:
  • Process contamination periodically influenced feed water corrosivity
  • Adverse effect on boiler cycles, chemistry and steam purity
Application: 3D TRASAR Boiler Technology
eROI:
  • Real time detection of upsets to prompt corrective action
  • Maximised quality of valuable returned condensate
  • Reduced demand for costly make up water
  • Improved energy efficiency
