Abstract
A system is used for removing catalyst from a tubular reactor vessel. A power box with a 110 volt to a 12 volt DC transformer is mounted outside the vessel and connected to a 110 volt power supply. An air manifold, also mounted outside the vessel, is connected to a high-pressure air supply and connects to several valves with a separate connection to the power box. Several workstations are placed on the tube sheet within the vessel. The workstation has a frame, a drum and reel assembly mounted on the frame along with a 12 volt DC motor. An air lance hose passes into the drum and reel assembly and, at the other end, connects to an air lance and vacuum assembly. A high pressure air hose connects the drum and reel assembly to one of the valves located outside of the vessel. A controller connects to the 12 volt DC motor to power the drum and reel assembly. The controller is also connected to the power box located outside the vessel and to a foot control. A seat is mounted on the drum and reel assembly.
