0.5 MW Pilot Plant (TUDA)

A big challenge in designing and modelling a gasification process is the high quantity of different, incomplete reactions that are involved. Many different factors influence the reactions, which makes it hard to predict the quality and quantity of the output syngas. Therefore, various experiments with innovative feedstocks are needed to validate the simulations. These will be carried out with the 0.5 MWth pilot plant of the EST institute, at the TU Darmstadt. This unique pilot plant complies with the requirements to carry out such experiments.

This 0.5 MWₜₕ facility, shown in Figure 1, was erected in 2010 within the framework of COORETEC – LISA. It was afterwards used in SCARLET project in 2017 and is currently being adapted and expanded for the upcoming investigations of the COORETEC – FABIENE project. The modular concept that was implemented allows for semi-industrial investigations in the fields of combustion, CO2 capture and gasification, and is unique in its dimension and design. Its main three components, are a 1 MWₜₕ combustion chamber and two circulating fluidized bed reactors, the CFB 400 and the CFB 600. Different processes may be implemented and investigated in this plant, such as Carbonate Looping, Chemical Looping, and High Temperature Winkler Gasification (HTW).

Within the framework of the LIG2LIQ project, a second separated feeding system for the reactor will be installed. With this expansion, it will possible to mix different feedstocks and perform experiments with waste, which will make a contribution to the research of alternative waste recovery.
