Continuous Processes for Special Polymers Aided by Novel Apparatus Concepts (KoPPonA 2.0)

The chemical industry is one of the most energy-intensive production sectors in Germany, and its production processes still offer considerable potential for energy savings. While the production of petrochemical raw materials and basic chemicals is already carried out in highly energy-efficient continuous processes, the production of pharmaceuticals, fine and specialty chemicals still generally uses batch processes with low energy efficiency in multi-product plants.

As part of the ENPRO Initiative I and II, modular and flexible plant concepts have been and are being developed in order to be able to use the advantages of a continuous production mode for the fabrication of smaller and special chemical products. A major obstacle to the rapid implementation of these new concepts is the occurrence of fouling and deposits, which can severely disrupt continuous operation. 

In the joint project KoPPonA 2.0, the implementation of continuous process concepts for various polymer specialties which are particularly susceptible to the formation of deposits is to be promoted. Therefore, plant operators, apparatus manufacturers, sensor manufacturers, material scientists and process engineers work closely together to elucidate the causes of coating formation and to ensure the operation of continuous plants through innovative approaches in apparatus design, surface modification and reaction control.
