Short presentation

Christian Dowidat began studies of Chemical Engineering in 2005 at the TU Dortmund. He finished in June 2010 with  a Diplom thesis "Comparison of conventional plant design to a modular approach". Since august 2010, he is working at the Laboratory of Plant and Process Design.



Due to rising energy prices the share of energy costs on the operating costs of process plants has increased. Using energy efficiently, not only the operation costs of a process plant but also carbon dioxide emissions can be reduced. This work is part of the BMBF-promoted project “Energy Efficiency Management”. As part of this work methods to increase the energy efficiency of process plants shall be developed. Deploying heuristics the operating parameters of the process shall be adjusted or more efficient alternatives for energy-intensive unit operations will be proposed. In addition possibilities shall be demonstrated how continuous operation of plants under partial load and batch processes can be made more efficient.
