Title: Koichi Igarashi: Innovator in Sulfur Dioxide Removal Technology

Introduction

Koichi Igarashi is a notable inventor based in Iwaki, Japan. He has made significant contributions to environmental technology, particularly in the field of sulfur dioxide removal. His innovative methods aim to enhance the efficiency of gas treatment processes while minimizing waste.

Latest Patents

Igarashi holds a patent for a method that effectively removes sulfur dioxide in the form of calcium sulfite. This method involves absorbing sulfur dioxide from combustion exhaust gas using an aqueous alkali sulfite solution. The process produces alkali bisulfite, which is then treated with calcium carbonate to form calcium sulfite. A key aspect of this method is the wet-powdering of calcium carbonate into a specific particle size, allowing for the re-use of filtrate in the absorption process. This innovative approach ensures that nearly no wastewater is discharged, and sulfur dioxide is recovered as highly pure calcium sulfite. He has 1 patent to his name.
