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 a good Nelson complexity index?
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. Higher-valued refineries on the NCI tend to be more costly to build and operate, but also produce more profitable outputs.
How do you calculate Nelson complexity?
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 used to measure the complexity of a refinery?
The complexity number for a refinery is calculated by multiplying the complexity factor for each process unit by the ratio of the process unit’s capacity to the refinery’s atmospheric distillation capacity, and then summing across all process units. This results in a number that typically falls between 5 and 15.
What is NRGF in refinery?
BEE Calculation MBN – Million British Thermal Unit per Thousand barrels per Energy Factor. (MMBTU / Barrel / NRGF) = (Fuel + Loss) NRGF – Complexity of the refinery.
What is EDC in refining?
developed equivalent distillation capacity, a method for comparing the operating costs of refineries. EDC provides a statistically tested method to compare cash operating costs of different refinery types and sizes.
Which refinery has the lowest specific energy consumption in India?
Bharat Petroleum Corporation Limited Mumbai Refinery (MR) is a compact lube refinery located in the heart of Mumbai, can process 12 million tons of crude, with lowest SOx emission and lowest specific energy and water consumption in industry.
What is Solomon EDC?
Definitions: EDC®: Solomon’s proprietary metric to normalize configuration, size, and complexity. EDC® is based on operating expense correlations. As a “new normality” unfolds and operators return to more typical staffing levels, we recommend reaffirming or implementing reliability strategies and methods.
Which refinery has the lowest specific energy consumption?
Jawaharlal Nehru Centenary Award for Energy Performance (2014-15) for the Lowest Specific Energy Consumption (MBN), was presented to IndianOil’s Mathura Refinery (Group-1); IndianOil’s Panipat Refinery (Group-2) and for RIL’s SEZ Refinery (Group-3).
What is Solomon study?
Solomon’s refining studies are designed to do just that—provide a competitive perspective and detailed gap analyses that help identify potential opportunities for efficiency improvement across all areas of operation.
What is the Nelson Complexity Index of a refinery?
Under the Nelson Complexity Index, the most simple refinery that only distills crude oil, called a “topping” refinery, is considered to have a complexity factor of 1.0. All other processing units are rated in terms of their cost relative to this unit.
What is measuring the complexity of an oil refinery?
Meaning. Its a measure of the sophistication of an oil refinery, where more complex refineries are able to produce lighter, more heavily refined and valuable products from a barrel of oil. The Nelson Complexity Index was developed in 1960 by Wilbur Nelson.
How to calculate the NCI of an oil refinery?
Some factors for various processing units: 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. ^ “Nelson Complexity Index” (PDF). pakpas.org. Retrieved 3 November 2016.
What is the Nelson index?
This index was developed in the 1960s by W.L. Nelson in a series of articles for the Oil & Gas Journal. The index measures the complexity and cost of each major type of refinery equipment.
