Title: Shigeru Nozawa: Innovator in Flue Gas Desulfurization Technology
Introduction
Shigeru Nozawa is a prominent inventor based in Kure, Japan. He has made significant contributions to the field of environmental technology, particularly in flue gas desulfurization. With a total of nine patents to his name, Nozawa's work focuses on improving methods for reducing sulfur oxide emissions from combustion processes.
Latest Patents
One of Nozawa's latest patents is a wet-type flue gas desulfurization plant and method that utilizes a solid desulfurizing agent. This innovative method involves bringing exhaust gas from combustion apparatuses, such as boilers, into contact with an absorbing liquid. The process effectively absorbs sulfur oxide from the exhaust gas, followed by the neutralization of the absorbing liquid that contains the absorbed sulfur oxide. The solid desulfurizing agent is retained in a neutralizing zone, where the upward flow of the absorbing liquid, possibly enhanced by air or water, creates a fluidized bed of limestone particles. This design prevents the coating of limestone by gypsum, thereby maintaining its reactivity. Notably, the coexistence of aluminum and fluorine in the absorbing liquid does not significantly impair the desulfurizing performance. This method also reduces the power and cost associated with grinding limestone while achieving higher desulfurization efficiency.
Career Highlights
Shigeru Nozawa is associated with Babcock-Hitachi Kabushiki Kaisha, a company known for its advancements in energy and environmental technologies. His work has been instrumental in developing more efficient and cost-effective solutions for flue gas treatment.
Collaborations
Nozawa has collaborated with notable colleagues, including Masakatsu Nishimura and Takanori Nakamoto. Their combined expertise has contributed to the success of various projects in the field of environmental technology.
Conclusion
