Abstract: The invention involves a scale collection device that is located within downflow reactor head for removing solids from feed streams to increase reactor operating cycle time without impact on effective reactor space for catalyst loading. More particularly, a filtering zone is located in an upper portion of a reactor vessel above a rough liquid distribution tray and a distribution tray.

Abstract: The invention involves a scale collection device that is located within downflow reactor head for removing solids from feed streams to increase reactor operating cycle time without impact on effective reactor space for catalyst loading and reactor pressure drop. More particularly, a scale collection device is located in an upper portion of a reactor vessel above a rough liquid distribution tray and a vapor-liquid distribution tray.
