Title: Innovations of Leif A Lindau in Gas Purification

Introduction

Leif A Lindau is a notable inventor based in Vaxjo, Sweden. He has made significant contributions to the field of gas purification, particularly in the efficient separation of gaseous mercury from gas mixtures. His innovative methods have the potential to greatly impact environmental safety and industrial processes.

Latest Patents

Lindau holds a patent for a method of purifying gas containing gaseous mercury. This method involves highly efficient separation of low contents of gaseous mercury from a gas mixture. The process requires the gas mixture to contact a solid sorbent made of powdered calcium hydroxide, which is partially converted to calcium chloride in an atmosphere containing hydrogen chloride. The optimal temperature for this process ranges between 350 K and 550 K. The contact between the gas and the sorbent preferably occurs in a fluidized bed, followed by separation in a dust separator. This method is particularly suitable for removing mercury from flue gases, such as those produced by refuse incinerators. In experiments, the mercury content in flue gas was reduced from 200 to 5 µg of gaseous mercury per cubic meter.
