Device for removing catalyst and other material from refinery and petrochemical reactors and other vessels

摘要

Methods and apparatus are disclosed for removing catalyst, absorbents and other materials from a reactor, guard bed, or other refinery or petrochemical vessel via a robotic or remotely operated device. A vacuum hose is connected to the device for removing the material from the vessel for ex-situ regeneration or disposal. The device moves around on the surface of the catalyst using motorized screws that grip to the catalyst material. The device is powered by hydraulic, pneumatic or electric motors attached to the frame of the device with supply and return hoses extending in and out of the vessel in line with the vacuum hose.
