Latest Patents

Helfritch's latest patents include a method for nitrogen oxide reduction and flue gas reheating. This invention pertains to a method wherein a catalyst surface is heated to an operating temperature to facilitate a catalytic reduction reaction in the presence of relatively cool flue gas. To avoid conventional complications, the catalytic reduction reaction is performed downstream of both particulate control operations and desulfurization procedures. The catalyst surface itself is strategically placed just before the stack, allowing for the reheating of flue gas prior to its exit into the atmosphere. Another significant patent involves the removal of nitrogen oxides from waste gases. This method contacts the waste gas with the products of the pyrolytic decomposition of methane containing CH and CH₂ radicals, effectively reducing the nitrogen oxides to nitrogen.
