Title: Innovations of John Haidinger in Flue Gas Desulfurization

Introduction

John Haidinger is an accomplished inventor based in Taipei, Taiwan. He has made significant contributions to the field of environmental engineering, particularly in the area of flue gas desulfurization. His innovative approach utilizes seawater to efficiently remove sulfur dioxide from flue gas streams.

Latest Patents

Haidinger holds a patent for the "Use of seawater in flue gas desulfurization." This patent describes a method for the efficient removal of sulfur dioxide from a flue gas stream using a scrubber. The process involves a recirculating aqueous stream containing magnesium hydroxide and magnesium sulfite, which act as SO.sub.2 absorbents. The magnesium sulfite is derived from magnesium hydroxide, produced through a reaction between soluble magnesium from seawater and calcium hydroxide added to the scrubbing system. The introduction of air oxidizes magnesium sulfite and bisulfite to magnesium sulfate. This magnesium sulfate can be converted back to magnesium hydroxide by reacting with additional calcium hydroxide, with gypsum as a by-product. Notably, gypsum is soluble in large amounts of seawater and can be returned to the ocean without causing adverse environmental impacts.
