Title: Innovations by Soon-Jai Khang in Flue Gas Treatment

Introduction

Soon-Jai Khang is an accomplished inventor based in Cincinnati, OH (US). He has made significant contributions to the field of environmental engineering, particularly in the treatment of flue gases. With a total of 4 patents, Khang's work focuses on innovative methods to reduce harmful emissions from industrial processes.

Latest Patents

Khang's latest patents include a method for treating flue gas through a multiple-field precipitator. This flue-gas treating device consists of a first section that functions as a dual-purpose sensible-cooling heat exchanger and electrostatic precipitator. The second section features a wet electrostatic precipitator, while a middle section connects the two. In the first section, the exchanger/precipitator cools the flue gas and captures most of the dust. The dust-reduced flue gas is then combined with an alkaline material in the middle section, leading to the formation of reaction products. These products, along with other pollutants, are captured by the wet electrostatic precipitator as a pollutant-laden liquid. This liquid is subsequently processed through heat exchangers and settling tanks to remove various pollutants such as sulfur oxides, metals, nitrogen oxides, and chlorides. Additionally, ammonia is liberated from the liquid and cycled back to the middle section for further reaction product formation.

Another notable patent involves a two-stage method for the removal of nitric oxides and sulfur oxides from flue gases. The first stage employs sodium sulfite sorbent injection to eliminate all nitric oxides, while the second stage utilizes sodium bicarbonate injection to remove sulfur oxides. The sodium sulfite product generated in the second stage is then transferred back to the first stage for injection.
