Description

There has never been a wider variety of alternatives to choose from to solve the mist elimination challenges that exist in the sulfuric acid drying and absorption towers. The specific needs of each plant depend on the type of plant and the priorities of its technical and operations management.
The principal types of mist eliminators employed to date have been the knitted wire mesh pad, the impaction-type candle, and the Brownian Diffusion-type candle. This paper discusses the benefits and limitations of each type to assist managers in making informed decisions about the best technology for their specific needs. It also compares the installation, maintenance, and operating costs that should be anticipated for the various options.
Also introduced are three new product developments that offer significant improvements over current technology:
•
Newly introduced DEMISTER® style **3 knitted wire mesh mist eliminator provides increased efficiency with low pressure drop in drying towers.
•
Newly introduced FLEXIFIBER® BD-LdP Brownian Diffusion candle mist eliminator provides reduced pressure drop with no loss in efficiency in absorber towers.
•
Newly introduced FLEXIFIBER® ICK-LF impaction candle mist eliminator provides increased service life with no loss in efficiency in drying and final absorber towers.
