Screening & Segregation Services

Clean Harbors’ screening units segregate spent catalyst and classify material size. Dust and fines from attrition created during the shipping and handling of catalyst are also removed. Our units can easily segregate and class four particle sizes in a single pass prior to loading. By screening the catalyst, broken pieces (chips and fines), which can increase pressure drop during reactor run operations, are removed. This is particularly important in situations where spent catalyst will be reused or in reactors with a history of severe operating runs. Our spent catalyst screening process also removes support material for reuse.
