Abstract:
Diesel Hydrodesulphurization (DHDS) is one of the key operations in a refinery
used in marking sulfur content in diesel fuel to be acceptable in the current
market. This work concentrates on sensibly enhancing multiplex DHDS efficiency
with a specific reference to the catalyst. In addition, it captures detail design
aspects of the design team such as equipment design HAZOP and economic
analysis.
The initial phases focused on the design and integration of the DHDS unit
operations, including the designation of the proper path for process flow and
evaluation of mass and energy balances. Finally, HAZOP study was conducted to
pinpoint hazards and operational risks from other processes for safety and
reliability of DHDS processes.
In this research, the performance evaluation of the catalyst is one of the major
considerations. Catalyst selection criteria and their properties such as activity,
selectivity, stability and cost were taken into consideration and various catalyst
selections were made basing on literature findings. These comparisons were
important since they helped in determining the best catalyst which should be used
for DHDS applications.
This work has intersections with both chemical engineering fundamentals and
recent developments in the use of data analysis; it has helped improve the
functionality of DHDS. Based on the results of this research, it provides actionable
insights to the petroleum refining industry on how to optimize the performance
of the DHDS process to a level that would have low impacts on the environment
while, at the same time, increasing efficiency and productivity
