Project Description

The one from Shell Catalysts in Leuna for the production of clay tablets was built production complex consists essentially ofof a over 30 m high extension with 5 levels. For the view from above downward-slopingproduction process raw materials and intermediate products are transported on chemical pallets and in containers from the receiving area on the ground floor to the top level (+24 m) of the new building, where they are stowed or directed to the side removal with individual access to each pallet. The top level of the adjacent, lower existing building is also served by a conveyor line arranged at a 90° offset on the 2. level (+6 m) . Here, the pallets are also stored, but with their ends facing forward according to the FIFOprinciple.
