Downstream is a term commonly used to refer to the refining of crude oil and the selling and distribution of natural gas and products derived from crude oil.

As many as 2,300 different products can be processed through a refinery. Typically the refined products are used in: 

  • Fuels for vehicles
  • Fuels for the generation of heat and power 
  • Raw materials for the petrochemical and chemical industries
  • Speciality products such as lubricating oils, paraffin, waxes and bitumen
  • Energy

Variation in product type, the available crude quality and requirements set by authorities mean that no two refineries are the same. To meet your specific needs the modular nature of our inventory means that we can quickly adapt our range to the application requirements of each refinery.
