Nelson
complexity index
From Wikipedia, the free encyclopedia
The Nelson complexity index (NCI) is a measure to compare the secondary
conversion capacity of a petroleum refinery with the primary distillation
capacity.[1]
The index provides an easy metric for quantifying and ranking the complexity of
various refineries and units.[2]
To calculate the index, it is necessary to use complexity factors, which
compare the cost of upgrading units to the cost of crude distillation unit.[3]
History
It
was developed by Wilbur L. Nelson in a series of articles that appeared in the Oil & Gas Journal[4]
from 1960 to 1961 (Mar. 14, p. 189; Sept. 26, p. 216; and June 19, p. 109). In
1976, he elaborated on the concept in another series of articles, again in the Oil & Gas Journal (Sept. 13, p. 81;
Sept. 20, p. 202; and Sept. 27, p. 83).
The NCI assigns a complexity factor to each major piece of refinery equipment
based on its complexity and cost in comparison to crude distillation, which is assigned
a complexity factor of 1.0. The complexity of each piece of refinery equipment
is then calculated by multiplying its complexity factor by its throughput ratio as a percentage of crude
distillation capacity. Adding up the complexity values assigned to each piece
of equipment, including crude distillation, determines a refinery’s complexity
on the NCI.
The NCI indicates not only the investment intensity or cost index of the
refinery but also its potential value
addition. Thus, the higher the index number, the greater the cost of the
refinery and the higher the value of its products.
In the second edition of the book Petroleum
Refinery Process Economics (2000), author Robert Maples notes that U.S.
refineries rank highest in complexity index, averaging 9.5, compared with
Europe's at 6.5. The Jamnagar refinery belonging to India-based Reliance Industries Limited is now one
of the most complex refineries in the world with a Nelson complexity index of
14.[6]
The new refinery began trial production on December 25, 2008. The former BP Texas
City, Texas refinery, newly acquired by Marathon Petroleum as their
Galveston Bay Refinery has a Nelson complexity index of 15.3 in 2013.
The Oil and Gas Journal
annually calculates and publishes a list of refineries with their associated
Nelson complexity index scores.
