GroupⅡ Base Oil Process
Premium Series Hydrocracking(HYC) Process
Premium series base oil utilizes Gulf’s hydro treating and
Texaco’s MEK (Methyl-Ethyl-Ketone) dewaxing process.
Super series base oil utilizes ExxonMobil’s MSDW™ catalytic
dewaxing and hydrofinishing process effectively combined with
Gulf’s hydrotreating process.
Group Ultra-S Process
Hydrocracking(HYC) Process Wax Hydroisomerization Process Hydrofinishing
Using VGO(Vacuum Gas Oil) as the main
feedstock, severe hydrocracking process
removes majority of impurities and
saturates most of aromatics to turn out
high quality waxy oils.
ExxonMobil’s MSDW™ (Mobile Selective
Dewaxing) catalyst isomerizes wax mole-
cules and n-paraffins in the waxy oils into
branched molecules, having lower pour
point, which are very desirable as superior
lubricating base oils, rather than cracking
them away as was the practice with the
conventional catalytic dewaxing.
The dewaxed oil is fine-tuned by removing
residual aromaics and impurities like
sulfur and nitrogen, containing compounds,
turning it into water-white and highly pure
final product.
