Advanced Cleaning Devices for Production of Green Syngas

In this note the objectives of a project financed from European Community in the FP7 to realize a cleaning system for a syngas obtained from the gasification of biomass will be reported. In order to us the obtained sysngas can be transformed with further catalytic processes previously eliminating sulphur chlorine, COS, HCN NH3 and tars.

Wood Chip Refiner Control

The authors treat the control of a chip refiner to produce wood pulp, where the incremental gain between the motor load and the plate gap is subject to sudden changes due to pad collapse. Passive adaptive control with fault detection, active suboptimal dual control, and dual-control solutions are discussed. For dual control, the choice of the control criterion is crucial, as it must reflect the pe
