Enhanced Energy Performance in Refinery Units: The Role of Light Naphtha Fuel Substitution

Enhancement of energy efficiency in refining units that deal with
petroleum is one of the major goals in ensuring that the operations are
sustainable and environmentally responsible. The research is intended
to assess the alternatives between heavy and light naphtha as the
furnace feed in refinery units, including the improvements in the
energy performance and reduction of emissions. The methodology
entails a thorough evaluation that incorporates combustion
performance analysis, economic evaluation, and environmental impact
assessment, which is based on operational data of the Najaf Refinery.
The findings show that replacing light naphtha with light combustion
results in enhanced combustion performance, as it contains less carbon
and has better fuel characteristics with a significant decrease in carbon
dioxide emissions. Moreover, the economic analysis demonstrates the
presence of significant cost savings that are related to fuel consumption
and operational efficiency, which proves the economic viability of the
suggested substitution. Implementation-related technical issues are also
determined, and suitable mitigation measures are suggested to facilitate
stable and safe operation. In sum, the results support the conclusion
that the extensive use of light naphtha instead of heavy naphtha is a
viable strategy to increase energy efficiency and decrease the
environmental risks at the same time, thus facilitating sustainable
refinery processes.
