RESIDUAL FUELS - Carbon Black, Clarified and Slurry Oil Testing

Residuum from vacuum distillation and cracking processes are typically called residual fuels. Residual fuels are primarily used in marine diesel applications and in industrial boilers. If necessary, gas oil or kerosene streams are blended to achieve the desired properties (i.e. viscosity etc.) for various industrial applications.

Testing is provided to oil refineries, oil suppliers, traders, and other clients, through a global hydrocarbons laboratory network staffed with experienced petroleum chemists and equipped with modern instrumentation. The crude oil and petroleum labs test to ASTM, ISO, IP, and other petroleum industry protocols.

In addition to providing the regular residual fuel testing, finished product quality checks, we also offer troubleshooting and contamination identification services. Our experienced team provides the expertise and resources you need to ensure a quality deliverable.
