Grading & guard materials

Maximum catalyst protection and optimum pressure drop management. With the increased levels of heavy and non conventional crude oils in the refinery diets, state-of the art catalysts need state of the art Grading and Guard Materials to create the best working environment mitigating pressure drop and eliminating contaminants.

Cycle length of a Hydroprocessing unit is typically controlled either by the catalyst activity (maximum allowable working temperature) or by the reactor pressure drop (maximum allowable pressure drop). Therefore, optimum Grading and Guard Materials system is definitely part of the success of a catalyst load allowing its maximum usage.

Based on its large experience and expertise, Axens has developed a large portfolio of products that address complex issues from dramatic pressure drop build-up to the severe catalysts poisoning. Axens has also developed enhanced diagnosis tools that allow proposing cost-effective solutions to our clients.
