Blending sharpness for fuels and lubrication oils

In oil refining operations, reduction of sulfur ‘giveaway’ can be achieved by improving blending sharpness to comply with Tier 3, Euro VI and other environmental regulations. Excellent repeatability at low sulfur level, visualized in the graph, ensures sharper blending and thus less giveaway.

Monitoring of key minerals in liquid food products

Nutrient and mineral fortification are essential steps during the production of many food products. Accurate fortification, combined with homogeneous mixing, will ensure that the final product always meets the label claim. 

Epsilon Xflow provides on-line monitoring of key minerals controlled in liquid products, including potassium, calcium and iron.

Elemental analysis within your process

X-ray fluorescence (XRF) is a non-destructive elemental analysis technology which enables you to measure your process streams without any sampling loss or chemical/physical changes. Real-time on-line XRF analysis provides fast optimization of many processes parameters and product properties.

Highly repeatable and accurate with low maintenance

The proven and robust Epsilon 3X technology used in the Epsilon Xflow is powered by the latest advances in excitation and detection technology. A well designed optical path, a wide range of excitation capabilities for light and heavier elements, and a fast high-resolution SDD detector system contribute to the power of the Epsilon 3X. The sum of all these innovations results in highly repeatable and accurate results with low maintenance.

Customizable to many production processes

The flexible design of the Epsilon Xflow makes it easily integrated into many different processes and process conditions. The solution is able to handle a broad range of environments, including harsh conditions due to:
  • Temperature
  • Pressure
  • Viscosity
  • pH value
  • Corrosiveness
  • Solvent polarity
Customizable to many production processes

Turn-key solutions

Our specialists and engineers have more than 50 years’ combined experience in the field of industrial XRF – which makes us the experts in delivering turn-key solutions globally. When installing a solution, we do not leave the site before the on-line analysis is up and running smoothly. 

Installations can include:

  • Sample conditioning
  • ATEX design
  • Sample recovery and waste management
  • Appropriate sheltering
  • Process stream selection
Turn-key solutions

Laboratory performance in every climate

Harsh conditions are common in plant environments. Several different features enable the analyzer to cope with harsh and changing climate conditions:

  • Real-time corrections for temperature and air-pressure variations
  • Heated electronics for operation in cold environments
  • Extra cooling capabilities to handle tropical conditions
  • Sheltering

Monitoring of liquids and liquors in mining operations

Real-time analysis of liquors and reagents during ore processing

To extract valuable metals like copper, nickel or uranium from ore, aggressive and often highly acidic liquids are used. The Epsilon Xflow can cope with challenging process conditions while maintaining the required accuracy and stability over longer periods of operation. When impurities are detected, the multi-elemental capability of the analyzer makes fast counteractions easy. The on-line analyzer provides direct and accurate feedback on the leaching process and saves expensive reagents, lowering processing costs per ton of material.

Mine waste water control

Mining operations need constant on-line monitoring for their wastewater to prevent damage to the local environment from harmful elements. Epsilon Xflow can detect traces of toxic metals and other elements on the spot –making immediate counteractions possible before the damage is done. This helps the mining industry minimize environmental impact and avoid penalties.
