Latest Patents

His latest patent, titled "System for handling high sulfur materials," addresses the challenges posed by sulfur oxides, which have a strong affinity for free lime, readily forming gypsum anhydrite. This innovative system utilizes on-gas heated to 2200°F or higher with reduced sulfur quantities, directing it to the preheat zone of a material treating apparatus. This method effectively removes large quantities of sulfur from gases evolved in rotary kilns. By applying lower sulfur content on-gas for preheating, the system significantly enhances its capacity to lower both sulfur and alkali levels in clinker production. The process incorporates substantially free lime in fine forms, introduced into the kiln off-gas stream to generate gypsum anhydrite, which can be removed and utilized as a by-product. Essentially, most of the remaining gaseous sulfur, not absorbed by the lime-bearing dust, is captured by the free lime in pellets situated in the preheat zone of the material treating apparatus.
