Martin: "The goal we had set was to run Empyro at full capacity within three years. We are very close to achieving this goal. When we look where we stand now, we are very satisfied. "
Ardy: "We have had a number of major challenges, including major wear in the sand pneumatic transport system. We first tried to solve this wear by optimizing the geometry by CFD studies and help from external expertise. This reduced the wear rate by half which was not yet good enough. In the end we managed to change the design in such a way that the area where the wear was taking place was no longer necessary. Wear in the sand system is now negligible.”
Martin and Ardy form a well-organized team. Martin: "Ardy is the one who analyzes a problem, comes up with solutions and puts it in motion. I provide feedback in this process, organize and plan the modifications and ensure that the plant documentation is up to date."
A crucial milestone was the financial close in December 2013. Ardy: "An absolute highlight was the moment we could actually give Zeton the order for the construction on Christmas Eve. Also, the transport of the modules from Zeton in Enschede to the site in Hengelo in the evening was impressive."
"Would it work? It worked!"
Martin: "Restarting the installation after the modification of the sand transportation system was a very exciting moment. Would it work? It worked!"
Currently we have had a one month maintenance stop to make further improvements to the installation. An important modification was made to the combustor in order to optimize the temperature control and heat balance in the system.
Both Ardy and Martin are very positive about the future. Ardy: "We have a state-of-the-art pyrolysis technology. Progress in the field of pyrolysis oil applications is now important to further develop the market. The government can play an important role to facilitate this development. We should strive for fossil fuel independency. "
Martin: "I'm incredibly proud of what we have achieved with such a small team. I would like to take this opportunity to give the team all the credits for their endless effort, intrinsic motivation and flexibility. Super!"
