Refining Characteristics

Naphtha
Yield is low but of good quality and highly reformable. Naphtha purchases may be needed to balance gasoline, petrochemical, and hydrogen production when Alba is included in the crude slate to offset Alba’s low naphtha content.

Middle Distillates
Cold properties, such as pour point, are excellent. However, burning qualities such as jet smoke point and diesel cetane index are poorer and specific gravity is higher compared to average traded crude oils. Refiners may need to adjust crude unit cut points, blend Alba’s mid-distillate with paraffinic middle distillate, add cetane improver, or hydrotreat mid-distillate to meet prevailing mid-distillate specifications.

Vacuum Gas Oil
Alba is VGO-rich, with much better/higher yields than most average traded crude oils. Refiners with VGO cracking facilities can upgrade the VGO to high value transportation fuels. Nitrogen levels are lower than most Latin American crude oils. Sulfur levels are medium. While sulfur levels are higher than normally found in North Sea crude oils, they are much lower than in Middle East and Latin American VGOs making Alba an excellent opportunity substitute for these crude oils.

Vacuum Residuum
VR content is high, but its quality is far superior in terms of sulfur and nitrogen content, carbon residue, asphaltenes and viscosity than VR from other heavy crude oils. Alba will produce higher quality fuel oil, and produces better visbreaker and coker feed, than VR from most other heavy quality crude oils.
