Applications of Low Density Ceramic Filters for Gas Cleaning at High Temperatures
Abstract
Low density ceramic filters are now available for incorporation into gas filtration units. Trials have been undertaken with such units on a variety of duties. These duties have mainly concerned the cleaning of gases from high temperature processes prior to their release to atmosphere. Other duties have used high temperature filtration as an integral unit operation, simplifying operating processes.
The paper presents the experiences of the authors with installations in a number of different applications in a variety of industries. The paper discusses the properties and performance of low density ceramic media in general terms and relates these properties to their performance in each of these applications. It identifies specific strengths and weaknesses of this type of medium and proposes projects in other industries which would benefit from the use of this technique.
The paper presents detailed, quantified case studies of the use of low density ceramic media in several industrial processes which are subject to the Environmental Protection Act.
