Storage tanks for every application

KEIL Anlagenbau has implemented a project which includes the installation of four storage tanks (100 m3 each) including piping and complete assembly for Heidelberg Cement AG, an internationally operating group producing construction materials for the building and construction sector. The storage tanks are filled with solvents and waste oils, which serve as fuel for a cement kiln. This is done in an environment and resource friendly manner compared to cost-intensive fossil fuels. The system complies with high requirements for explosion protection.

The biggest challenge for KEIL was the required use of various storage media with different chemical composition. Therefore, special focus was given to finding the right technical solution to increase corrosion resistance. Additionally, high precision monitoring cycles were developed in cooperation with the German Institute of Civil Engineering (DIBt).

The tank trucks deliver the materials which are pumped into storage tanks using the gas displacement technique. The gases, which are displaced from the tanks during the filling process, are then safely returned to the tank trucks. Pumps and pipelines are used to transfer the stored media to the cement kiln. Parts of the storage tanks and pipelines are heated (up to the range from -15°C to 90°C).
