Mitigating the Risks

In today’s new reality, with many refineries running below the severity that they were designed for, it could be straightforward to use this spare capacity to process renewable feeds.

However, it is important to be aware that adding a renewable feed can affect unit operation in several ways. Hydrogen consumption and heat release will increase, for example, and there are the risks of increased corrosion and fouling. Also, there may be greater difficulty with blending in the diesel pool because of degraded cold flow properties.

Some of these risks are new to hydroprocessing though not to other parts of Shell’s business. For example, the same corrosion mechanisms occur in its upstream assets, so Shell Catalysts & Technologies is able to draw on established tools and techniques to address them.

Consequently, our consultants are working with refiners around the world to help determine these risks and evaluate mitigation measures to minimise or eliminate them. These may include:

  • Corrosion studies to evaluate carbonate cracking risks;
  • Catalyst activity and life cycle assessments;
  • Reactive hazard safeguarding analyses;
  • Product quality impact reviews; and
  • Heat integration and equipment assessments.
