The Nelson complexity index (NCI) is a measure to compare the secondary conversion capacity of a petroleum refinery with the primary distillation capacity. The index provides an easy metric for quantifying and ranking the complexity of various refineries and units. To calculate the index, … See more It was developed by Wilbur L. Nelson in a series of articles that appeared in the Oil & Gas Journal 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 … See more $${\displaystyle {\text{NCI}}=\sum _{i=1}^{N}F_{i}\cdot {\frac {C_{i}}{C_{\text{CDU}}}}}$$ Where: • $${\displaystyle F_{i}}$$ is a complexity factor • $${\displaystyle C_{i}}$$ is a unit capacity See more 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 … See more • Oil and Gas Journal, Nelson Complexity index See more WebAug 20, 2024 · HPCL’s was $5.86 per barrel against $6.83.
