CAROL Robotic Catalyst Unloading
The world’s first remote controlled commercial catalyst removal robot
CAROL (Catalyst Removal Amphirol) is a robot that sits on the surface of the catalyst, moving around on the material as it is vacuumed. The hydraulically powered screws (amphirols) provide buoyancy, propulsion and manoeuvrability on the loose granular material. A vacuum hose is connected to the robot via a remotely adjustable nozzle, allowing for maximum catalyst removal rates. The robot is lowered through the vessel manway on a winch and is controlled remotely via joysticks and video monitors.
