Our hydrotreating technology is based on extensive research and design in catalysts and processes over many decades, combined with lessons learned from our affiliates’ operational experience.
In Shell Catalysts & Technologies’ hydrotreating process, oil fractions are reacted with hydrogen in the presence of a catalyst to produce high-value clean products. The operating conditions will depend on the final application.
The heart of our hydrotreating process is the reactor section, which features a high-pressure reactor vessel and state-of-the-art catalyst and reactor internals technology. The process configuration is tailored and optimized for each application to suit operating requirements and customer-specific project economics, which provides clear and sustained advantages.
Past experience supports the potential for better mechanical availability, on-stream factor, and utilisation. The turnaround duration can be reduced by as much as 8-16 days.
Conventional trickle phase units for distillate hydrodesulphurisation units are based on the two- or four-separator design concept. Shell Catalysts & Technologies’ designs have improved heat integration, which can help to reduce energy costs. Charge heaters in Shell ultra-low-sulphur-diesel units have up to 25°C lower temperature differentials across them, which is a direct measurement of energy efficiency. Moreover, Shell Catalysts & Technologies’ designs have helped to reduce the total equipment count and the capital and operating costs.
