Treatment of fly ash for sound material utilisation

Summary


The research project consists of following tasks:
1) Analysis of the current literature (VUB-CTW):
-on volatilisation and condensation of heavy metals;
-on methods to characterize fly ash particles.
Carrying out computer based thermodynamic studies (VUB).
2) Comparison of different thermal separation techniques for heavy metals. Making of kinetic studies:
-chloridising volatilisation of fly ash (MHW-TUC);
-equilibrium experiments, real and synthetic ashes (MHW-TUC); -kinetic investigations (MHW-TUC);
-laboratory experiments using pyrohydrolysis (TNO);
-segregation technique (CTW);
-reductive evaporation (CTW).
3) Carrying out pyrohydrolysis experiments in fluidized bed (TNO, CTRV).
4) Carrying out evaporation/segregation experiments on small pilot scale (CTW).
5) Design of a pilot plant (CTRV).
6) Investigation on heavy metals condensation, especially on fly ash carrying out experiments on
sequential condensation (VUB).
7) Investigation on processing and utilisation of metal condensate (MHW-TUC).
8) Investigation on assessment and utilisation of mineral product: -utilisation as a civil construction material (CTW);
-investigation on ecological properties (TNO).
