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 in an upper portion of a reactor vessel above a rough liquid distribution tray and a vapor-liquid distribution tray.
Claims22
A reactor comprising an upper portion and a lower portion wherein the upper portion contains a scale collection device above a rough liquid distribution tray, wherein a vapor-liquid distribution tray is located below the rough liquid distribution tray and wherein the scale collection device comprises a cylindrical wall attached to the bottom plate of the rough liquid distribution tray and a layer of spacing material sitting on the rough liquid distribution tray bottom plate having a plurality of perforations and a series of chimneys with caps affixed to the rough liquid distribution tray.
An apparatus comprising an upper portion and a lower portion wherein the upper portion contains a scale collection device located above a rough liquid distribution tray, wherein a vapor-liquid distribution tray is located below the rough liquid distribution tray and wherein the rough liquid distribution tray 22 comprises a plurality of chimneys and caps.
