Title: The Innovations of Karl-Heinz Dorr

Introduction

Karl-Heinz Dorr is a notable inventor based in Mainz, Germany. He has made significant contributions to the field of environmental technology, particularly in the purification of flue gases. With a total of 14 patents to his name, Dorr's work has had a substantial impact on industrial processes and environmental protection.

Latest Patents

One of Dorr's latest patents involves a process for purifying flue gases. This innovative method addresses the reduction of NO.sub.x content and the oxidation of SO.sub.2 to SO.sub.3 through catalytic processing. The SO.sub.3 is then condensed into sulfuric acid. To enhance the efficiency of this process and prevent catalyst deterioration, the flue gas undergoes fine dedusting using hot dilute sulfuric acid. The concentration of sulfuric acid and its temperature are carefully adjusted based on the water content of the flue gases, ensuring minimal transfer of water between the flue gases and the dilute sulfuric acid.
