Common applications

  • Chemicals (e.g. Plastics, Aromatics, Olefins and Parafines)
  • Refinery Products (e.g. Crude Oil, Naphta, Lubricants, Gasoline, Diesel Fuel, Fuel Oil)
  • LPG and Gases (e.g. Pentane, Butane, Propane, Propylene)


Regulating bodies all over the world have set challenging low levels of allowed Sulfur and Nitrogen concentrations in organic fuels for the present and near future in order to protect the environment.

Oil refineries produce a wide range of air and water emissions that can be harmful to the environment. Some of the contaminants are present in the original crude oil, while others are a result of refinery processes and operations. Air emissions include Sulfur dioxide (SO2) and Nitrogen dioxide (NO2), which have to be monitored.

During the production process of oil products, Nitrogen oxides (NOx) are formed in the gases of the furnaces, which are corrosive to steel. In addition, during catalyst reforming, naphtha is pretreated to remove contaminants like Chlorine, Sulfur and Nitrogen which could poison the catalyst. Right before the end-product is sent to blending and storage, the oil product is treated once more to remove the last amounts of Nitrogen and Sulfur completely.

Refineries need to monitor and control the Total Nitrogen and Total Sulfur content in the feedstock. This is the only way to tune their processes at the highest level of efficiency and also important in order to protect the quality of fuels which leads to a cleaner environment.
