Creator of Solutions to Address Climate, Energy & Environmental Issues
Solid recovered fuel (SRF) gasification holds the dual promise of eliminating waste and producing energy. However, for it to work, the substances generated during the gasification process must be understood. Industrial equipment manufacturer Leroux et Lotz Technologies and SRF supplier Sibuet Environnement turned to Liten to design and build a complete sample collection and analysis system to test the particles, condensable substances, and gases produced by the reaction.
A sample-collection and testing bay was designed and tested in the lab. It was then installed on the reactor to produce quantitative and qualitative analyses of the substances (permanent gases, organic and inorganic pollutants) produced by the reactor and the thermal tar cracking system. "The gases coming out of the reactor are drawn through removable filters kept at a temperature of 300 °C," said a researcher. "Once the particles are removed, the gas is directed through a heated line to a sparging unit where the tars are trapped. The tars are then dosed in the lab . The permanent gases, which make up the usable product, are then analyzed in line." The system can be used for mass balance analyses and to calculate reactor yields.
Once operation of the system has been validated on Leroux et Lotz's test reactor in Nantes, France, Liten will contribute to the initial test campaigns on actual syngas.
