What is a high Nelson complexity index?
Key Takeaways. The Nelson Complexity Index (NCI) takes account of what types of petroleum products an oil refinery can produce. Measured on a scale from 1 to 20, the higher the value on the NCI, the more sophisticated and complex products the refinery can produce.
How is Nelson complexity index calculated?
Example. If an oil refinery has a crude distillation unit (100 kbd), vacuum distillation unit (60 kbd), and catalytic reforming unit (30 kbd), then the NCI will be 1*(100/100) + 2*(60/100) + 5*(30/100) = 1.0 + 1.2 + 1.5 = 3.7.
What is a complex refinery?
A complex refinery is one with a large number of high-value conversion units. This is done by assigning a complexity factor to each type of process unit, and then weight averaging these values based on each unit’s capacity relative to the size of distillation capacity at the refinery.
What is complexity index of a refinery?
Complexity index (CI) designates the capabilities of a refinery to upgrade the lowest quality crude to the highest quality refinery products, including fuels and petrochemicals.
What is NRGF in refinery?
MBN – Million British Thermal Unit per Thousand barrels per Energy Factor. (MMBTU / Barrel / NRGF) = (Fuel + Loss) NRGF – Complexity of the refinery. Based on Refinery submitted data FY 2014-15.
What is Hydroskimming refinery?
Hydroskimming is a refining configuration that consists only of atmospheric distillation, reforming, and hydrotreating. It gets its name from having a reformer (“hydroskimmer”) as its only real conversion unit.
What is MBN energy?
Following this international guideline, BEE has developed its indigenous Energy Performance Index which links SEC with the complexity/ criticality of any refinery and it is called – MBN (Million British Thermal Unit per Thousand barrels per Energy Factor).
