ECO-DIST II

The overall objective of the ECO-DIST II project (hereafter ECO-DIST) is to continue the
development of the novel horizontal diabatic distillation and evaporation technology to provide a
substantial reduction of the specific energy consumption and capacity cost of fuel ethanol
production.
This will be achieved by:
• Scale-up the new droplet generation and ejection system, developed during the Synferon
project supported by Innovationsfonden.
• Improving the ability of the folded heat transmission wall to resist a pressure up to one bar
higher at the condensation side relative to the evaporation side.
The interaction between the droplet ejected with high speed against the folded heat
transmission wall will provide a very high heat transfer coefficient. Combined with the
great surface area of the folded wall will generate a lot of vapor moving out of the folds,
counter current to the incoming droplets.
The result of the experimental development work of ECO-DIST will be high capacity and low
production cost from the distillation/evaporation modules in 20 feet containers. Furthermore, ECODIST
will investigate the feasibility of sequential distillation with mechanical vapor
recompression, which will provide extremely low energy consumption but also increase the capital
expenditures to the compressors.
