As such, systems with a high dry film thickness, as well as good abrasion resistance, are recommended for this area, often trowel applied to reach the high thicknesses.
thus, several wet fgd systems have been developed and are in commercial use, including a variety of scrubbing processes involving limestone or hydrated lime slurries the aim of the present study is to investigate the sulfation properties of the six different natural limestone and hydrated lime slurries.flue gas desulfurization by limestone and hydrated lime slurrie introduction flue gas desulfurization processes are usually categorized as wet and dry or semi-dry systems.the aim of the present study is to investigate the sulfation properties of the six different natural limestone and hydrated lime slurries.
oct 15, 2000 hydrated lime is normally used as SO sorbent in spray dry scrubbers, whereas limestone is considered unreactive under conditions prevailing in such a system. however, limestone is more easily available and several times cheaper than hydrated lime. We tried to use limestone to remove SO from flue gas in the semidry fgd process with a powder-particle spouted bed.In europe the production of fgd by-products, mainly gypsum, was estimated at more than mt, with their main use in the wallboard industry .researchers have also reported the utilization of fgd by-products to control soil ph, 4,5 where it was proven that soil properties were improved and production increased by adding fgd
