abstract

The TURBOSORP® -process is a dry flue gas cleaning process to remove certain pollutants like SO2 , HCl, Hg, heavy metals, dioxins and furans. The main principle of this process is to bring flue gas in an intensive contact with Ca(OH)2 , open hearth furnace coke, water and recirculated material in the Turboreactor. The Turboreactor operates as circulating fluidized bed in the manner of fast fluidisation. The gas/solid mixture leaves the Turboreactor at the top and the solids are separated in a fabric filter from the flue gas. More than 99% of the separated solids are recirculated to the Turboreactor and the rest leaves the process as product. Due to the high sorbent recirculation percentage a high sorbent utilization and low stoechiometric rates are reached in the TURBOSORP® -process. Due to the fact to have plants in operation for the spray absorption and for the TURBOSORP® process, a comparison definitely showed advantages for the TURBOSORP® process. Experiences of the plant start up of a TURBOSORP® plant in Poland concerning optimisation in pressure loss and hydrodynamics of the Turboreactor using CFD-Simulation are presented. Results concerning mercury and dioxin separation in our Turbosorp® pilot plant after the refuse incinerator MV Spittelau, Vienna, are discussed.
