Detailed Information

Exhaust Gas Condensation: Challenges and Opportunities

Exhaust gas condensation plays a major role in many engine related applications. On the one hand this physical effect gives rise to large potentials like onboard water collection from the exhaust gas stream, on the other hand critical challenges such as corrosion, fouling and blocking of coolers occur. This condensation is attributed to the inherent exhaust gas composition containing water, hydrocarbons and several acidic components. A thorough understanding of the involved processes and the capability of precisely describing these processes is the key to design and optimization of your engine components and processes.

Our Unique Condensation Models and Experimental Equipment

Recently our experts developed models describing the interrelated vapor pressure of the three components water, sulfuric acid and nitric acid. Together with novel condensation models in 1D and 3D contexts we can precisely predict condensate mass flows and condensate composition of your systems.

The basis for this thorough simulation work is our state of the art equipment:

  • Engine test beds for exhaust gas generation
  • Synthetic gas test benches for detailed investigations on gas composition impacts
  • Chemical lab for analyzing condensates and deposits
  • Several successful projects with well-known engine manufacturers and Tier I suppliers show the benefits our approach can offer to your company as well.
