With the increased levels of heavy and non-conventional crude oils in refinery diets, state-of-the-art catalysts need state-of-the-art Grading and Guard Materials to create the best working environment by mitigating pressure drop and eliminating contaminants.
The 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, an optimum Grading and Guard Materials system is definitely part of the success of a catalyst load allowing its maximum usage.
Based on its extensive experience and expertise, Axens has developed a large portfolio of products that address complex issues from dramatic pressure drop build-up to severe catalysts poisoning. Axens has also developed enhanced diagnostic tools that allow us to propose cost-effective solutions to our clients.
