S2 POLAR Applications

Refineries – From Ultra-Low Sulfur to Crude Oils

Refineries – From Ultra-Low Sulfur to Crude Oils

Sulfur concentrations are strongly regulated in automotive fuels. The current sulfur limit is at 10 ppm in many countries around the world and others are to follow. This specification requires the monitoring of Ultra-Low Sulfur (ULS) limits in diesel and gasoline, not only in refineries but also along the downstream supply chain including transport in pipelines, storage at terminal stations and tank farms, and inspection at petrol stations.

The S2 POLAR complies with the following S international norms:

  • ASTM D7220, D4294
  • ISO 13032, 20847, 8754
  • IP 336, 496, 532
  • JIS K2541-4


It’s not all about sulfur: In refinery processes other elements are required to be monitored as well. Such monitoring include e.g. Ni and V (ASTM D8252) and Fe as they have a negative impact on catalysts in Fluid Catalytic Cracking (FCC) units or Cl as source of corrosion in piping and tubes (ASTM D4929).

With its multi-element capability, the S2 POLAR is well suited for the analytical demands of refineries in one single instrument.
