Management of detached plumes in cement plants

The paper examines the phenomenon of detached plumes in cement plants. A discussion of reasons why such a plume forms is followed by a presentation of the various types of detached plumes (steam plumes, organic plumes, sulfuric acid mist, ammonium salts, etc.). A discussion of the chemistry occurring to cause these plumes is then offered, followed by a number of remediative measures that may be effective in ameliorating these plumes, offered on a site-specific basis. Emphasis is placed on the fact that to eliminate such plumes, one or more of the contributing chemical species must be controlled.
