Title: James R. Donnelly: Innovator in Flue Gas Desulfurization

Introduction

James R. Donnelly is a notable inventor based in Bailerup, Denmark. He has made significant contributions to the field of environmental technology, particularly in the area of flue gas desulfurization. With a total of 2 patents, his work focuses on processes that enhance industrial utility while addressing environmental concerns.

Latest Patents

Donnelly's latest patents include a process for flue gas desulfurization that involves the treatment of spent absorbents. These spent absorbents, resulting from the desulfurization of flue gas in a spray drying-absorption process, contain substantial amounts of sulfite, such as calcium sulfite. His innovative method oxidizes the sulfite into sulfate by heating the spent absorbent in the presence of an oxygen-containing gas at temperatures ranging from 350°C to 600°C. This process converts spent absorbents into materials with industrial utility.

Another significant patent is the Fluid Bed SOX/NOX process, known as 'hydrated calcine absorption.' This process simultaneously removes sulfur oxides (SOx) and nitrogen oxides (NOx) from gaseous mixtures, such as flue gases and industrial waste gases. The gaseous mixture is contacted with a particulate alkaline earth hydroxide in a moving bed reactor, preferably a fluid bed reactor, at temperatures between 85°C and 150°C, in the presence of water vapor and oxygen. A baghouse or other particle removal means is employed to extract solid materials, such as fly ash and reaction products, from the treated gaseous mixture.
