Existing energy used more efficiently
March 2013 – At the fully booked Planners' Day at Bietigheim, the business unit Clean Technology Systems presented solutions for utilization of the waste heat, and among them an innovation that is unique all over the world. Around 100 engineers from all over South Germany got information about energy efficient technologies that allowed the industry to make a contribution to the energy turnaround. The resonance was so positive that the event will be repeated in May.
"We do not want to generate regenerative energies but make sure that the existing energy is used more efficiently", says Joachim Kaufmann, Managing Director CTS.
The following figures show the potential: The industry uses 30% of the total final energy consumption in Germany, equaling 700 TWh/a. Of these, 400 TWh/a fall to the generation of process heat, and 30 to 40% of this volume is lost as waste heat. At least 30 TWh/a could be saved in an economically viable manner, corresponding to the output of three nuclear power plants.
Dürr offers an extensive portfolio of technologies that complement each other and improve the energy efficiency in widely different fields of industry.
The Dürr affiliate thermea Energiesysteme presents a solution for compressed air dehumidification that is unmatched worldwide: Refrigerant dryers of the series thermeco2 are the first systems to use the environmentally friendly refrigerant CO2 to dry compressed air for applications in the automotive industry. Compared to conventional systems, which work with refrigerants such as the controversial R134a and the soon-to-be banned R22, the climate-neutral CO2 refrigerant dryer from thermea offers important advantages, such as greater security of investments and sustainability in production through a natural refrigerant with low safety requirements.
Jochen Fink, Managing Director of Dürr Cyplan, presents the wide product range of Clean Technology Systems. He emphasizes that companies can increase their competitiveness by using these technologies, and that Dürr offers "solutions with export potential". Christian Matt from TÜV Süd informed about integrated energy analyses of production facilities and buildings (including IT).
In the Dürr Technikum, the participants of the Planners' Day had the chance to inspect a compressed air refrigerant dryer and an ORC system by Dürr Cyplan (for more information on this technology, see the article "Electricity from waste heat: Increasing demand for ORC systems") and a Compact Power System. The Compact Power System is based on gas turbine technology, combining highly efficient power and heat exchanger for decentralized production of electricity and heat.
