Zeolyst International

Criterion’s link to Shell Global Solutions is important for several reasons. First, it provides us with a deep insight into industry needs and trends: a real feel for the business from the viewpoint of an owner and major refinery operator.

Second, we gain access to a wealth of refinery technology, expertise in computer process modelling and optimisation, and an outstanding science and engineering resource, which is particularly valuable when it comes to more fundamental catalyst research.

From a customer standpoint, our link with Shell Global Solutions, a major refinery process technology licensor, opens the way for genuinely integrated and customised solutions. These encompass process technology, reactor internals and catalysts, all three elements being of the highest standard. Customers have the advantage of a single point of contact and responsibility for projects varying from those designed to improve operations, typically involving drop-in solutions, through scheduled turnarounds and revamps, to major expansions and completely new units demanding significant investment.

Over the past 10 years, Criterion has undertaken more than 150 projects involving the provision of hydroprocessing technology, reactor internals and catalysts. In projects like these, there is less need to compromise and more chance of being able to formulate a genuinely integrated solution. Unit performance is improved as a result. In every project and sale, Criterion and Shell Global Solutions respect the integrity of customers’ proprietary information.

Internals technology

Criterion offers Shell Global Solutions reactor internals technology, including filter trays, high-dispersion distribution internals, ultra-flat quench interbed internals, catalyst support grids and bottom baskets. Hundreds of commercial applications have proved the benefits of such technology in terms of raised reactor volume utilisation, reduced fouling, prolonged catalyst cycle lengths, more uniform product quality and reduced reactor hot-spot formation.
