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.
Claims23
A reactor comprising an upper portion and a lower portion wherein the upper portion contains a scale collection device wherein a filtering zone is located above a rough liquid distribution tray and wherein a vapor-liquid distribution tray is located below the rough liquid distribution tray, wherein the upper portion comprises a cylindrical side wall which is coupled 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 wherein a filtering zone is located above a rough liquid distribution tray and wherein a vapor-liquid distribution tray is located below the rough liquid distribution tray, wherein the filtering zone contains liquid overflow chimneys, wherein the upper portion comprises a cylindrical side wall which is coupled to the rough liquid distribution tray.
