With a total of 2 patents to his name, Dunnery's work is recognized for its innovative approaches to gas treatment processes.

Latest Patents

Dunnery's latest patents focus on processes for removing sulfur dioxide (SO₂) from gas mixtures. The first patent describes an improvement in the selective removal of sulfur dioxide with respect to carbon dioxide. This process involves contacting a gas mixture with an aqueous absorbent solution, such as alkanolamine or alkali metal hydroxide, to create a SO₂-rich solution. The solution is then moved to a stripping zone where sulfur dioxide is driven off, resulting in a SO₂-depleted solution that is recycled. The improvement lies in the removal of heat stable sulfur oxyanions using an anion exchange resin, which enhances the efficiency of the process.

The second patent also addresses the removal of sulfur dioxide from effluent gases. Similar to the first, it involves contacting a gas mixture with an aqueous absorbent solution. The innovation here is the use of a weak base anion exchange resin to remove heat stable sulfur oxyanions, which can be regenerated through specific chemical processes. This method further optimizes the treatment of gas mixtures containing sulfur dioxide.
