Specialty Base Oil
The HT Severe Hydrocracking makes the difference
Conventional processing such as solvent refining can result in a base oil that is 70-85% pure and is pale yellow or amber in colour.
The HT purity process used by Petro-Canada produces crystal-clear, 99.9% pure base oils that clearly outperform traditional solvent-refined materials. Petro-Canada offers a range of PURITY™ base oils that:
- Have a high viscosity index (VHVI fluids have a Very High Viscosity Index)
- Deliver synthetic product performance at a lower cost
- Have low volatility, high thermal and oxidative stability, and excellent low temperature capabilities
HT Severe Hydrocracking advantages
The HT Severe Hydrocracking process virtually eliminates the aromatics and impurities in our base oils – often less than 0.5%. By comparison, the aromatics content of Solvent Refined base oils is between 10 and 35%.
Hydroisomerization adds synthetic-type performance
In 1996 Petro-Canada added a new base oil manufacturing facility that added Hydroisomerization wax conversion capabilities. The result was our line of PURITY VHVI synthetic base fluids with improved low temperature fluidity, very high viscosity indexes, and performance characteristics very similar to polyalphaolefins (PAO).
