Crude Unit Contaminant Removal

Processing lower quality crude oils such as those containing high levels of oil soluble metals, inorganic metal contaminants and tramp amines provide the potential for higher profit margins. Unfortunately the presence of these contaminants can raise the risk and reduce the benefit of processing opportunity crudes. The RESOLV™ contaminant removal programme addresses these challenges and minimizes their impacts.

Process a Wider Variety of Challenging Crudes

Both a chemical and an operational solution, our RESOLV programme includes our newest and most innovative technology to effectively remove contaminates such as calcium, iron, tramp amines and other metals, allowing the refinery to process a wider variety of challenging crude oils.

Our proprietary chemistries remove these troublesome contaminants and are characterized by:

  • High removal efficiencies
  • High solubility in water
  • Minimum impact on the crude distillation unit and the waste water treatment plant


Tramp Amine and Calcium Removal Through Desalter pH Management​

Effective contaminant removal

helps improve operations​

  • Removing tramp amines helps reduce overhead corrosion risks due to amine salting

  • Removing calcium helps reduce fouling downstream of the desalter and catalyst deactivation 

Crude blend flexibility

supports efficient processing

of opportunistic crudes​

  • Helps improve solids wettability and reduce oil under carry

  • Helps improve resolution of water in crude stabilized emulsions

Excellent product properties

help protect refinery assets

  • Chemistry formulated with corrosion inhibitor

  • Low product toxicity and odour

  • Low to minimal risk to WWTP

  • Minimal acid transfer to desalted crude
