Title: Innovations of James David Colley
Introduction
James David Colley is an accomplished inventor based in Austin, Texas. He holds three patents that showcase his expertise in flue gas desulfurization systems. His innovative approaches have contributed significantly to environmental technology.
Latest Patents
One of his latest patents is a method for converting lime-based wet flue gas desulfurization systems to limestone-based systems. This invention allows a flue gas desulfurization unit to operate using limestone under inhibited oxidation conditions. A ball mill grinding unit may be installed to crush the limestone, producing a suspended slurry of fine limestone particles that is pumped to the reaction vessel. The process maintains a pH range of 3.0 to 6.5, optimally around 5.0, to enhance the dissolution rate of the limestone reagent. Additionally, the post-conversion process may require the addition of organic acids and oxidation inhibitors to improve sulfur dioxide removal from the flue gas.
Another significant patent is an apparatus for desulfurization. This invention utilizes limestone as an absorbent in a double loop system. The flue gas is introduced into a quenching zone for contact with a first slurry of limestone, followed by further contact with a second limestone slurry in an absorbing zone. The two slurries are supplied from a mixing zone where water and limestone are charged, and air is introduced to convert calcium sulfite to gypsum.
