Enhanced condensation of organic volatiles

The condensation of volatiles is an important topic on the R&D agenda of Yilkins. Volatiles condensation is not new, as it is part of pyrolysis oil condensation and used to produce chemicals. Yilkins wants to develop a condensation step (VOLCON) with multiple purposes:

  • Fatty molecules represent the majority of the energy content of the volatiles, the torrefied product can be further enriched in NCV instead of applying a volatiles combustion step. This is a crucial technology for a ‘plug-in torrefaction unit’ into existing wood pellet plants;
  • Higher NCV torrefied pellets can be produced without losing pellet durability;
  • Beside torrefied pellets, condensed volatiles can create added-value products (e.g. fine chemicals and flavor & fragrant substances). 

Evidence of the above-mentioned opportunities can be found in literature. Today there is not yet a technology available to condense specifically desired fractions of volatiles. Yilkins is currently developing such options together with its partners. The Yilkins objective is to design and demonstrate the VOLCON unit for the condensation of volatiles as well as their use as a hydrophobicity pelleting agent.

The P4S partner project that just started has been granted an EFRO subsidy of € 2 million wherein an R&D budget is available for the development of volatiles condensation (for smoke water production). The aim of the project is to build a small condensation unit connected to our demonstration unit in 2020 and a commercial one (1,6 tph black pellet production) in the project P4S in Almere, which is planned to start commercial production in 2021.
