Title: Innovations of Masao Hino in Combustion Exhaust Gas Treatment

Introduction

Masao Hino, an influential inventor based in Hiroshima, Japan, has made significant contributions to the field of environmental technology with a focus on combustion exhaust gas treatment. With an impressive portfolio of 14 patents, Hino's innovations address the pressing issue of hazardous emissions from combustion processes.

Latest Patents

Hino's latest patents revolve around advanced combustion exhaust gas treatment systems designed to efficiently remove dust and selenium (Se) from emissions. He proposes five distinct systems:

1. The first system involves cooling combustion exhaust gas to 350°C or less, leading to the separation of dust while transforming selenium into an insoluble compound for easy separation.

2. In the second system, after dust separation, a selenium elution preventive agent is added, allowing the dust to be formed into a manageable scale.

3. The third approach details the collection of dust using a dust collector, forming it into a slurry using circulation liquid from a desulfurization apparatus. Here, tetravalent selenium in the dust slurry is converted into an insoluble compound for solid-liquid separation.

4. The fourth system emphasizes the heating of separated dust to gasify selenium, which is then treated within a desulfurization apparatus, eventually forming a slurry and making selenium insoluble.

5. Lastly, the fifth system introduces a treating agent mixed with part of the circulation liquid in a desulfurization apparatus, which is then sprayed into combustion exhaust gas to ensure selenium remains insoluble.
