Apparatus and Method for Removing Mercury Vapor from a Gas Stream

A metallic filter effectively removes vapor from gas streams. The filter captures the mercury which then can be released and collected as a product. The metallic filter is a copper mesh sponge plated with a six micrometer thickness of gold. The filter removes up to 90% of mercury vapor from a mercury contaminated gas stream.

Gas Analysis by Absorption

There is practically only one method of gas analysis. This was worked out many years ago by Bunsen, Hempel, and Winkler and consists in the successive absorption with different chemicals of the various constituents of the gas. The only improvement to this method is the oxidation and combustion of different components of a mixture followed by absorption.
