INTRODUCTION

FIBRE BED MIST ELIMINATORS are used to provide the highest possible collection efficiency for process conditions requiring stringent performance
levels.
The EVERFIBRE BED MIST ELIMINATOR is manufactured under license from Begg Cousland & Co. Ltd., U.K.(www.beggcousland.com). These mist eliminators are the cumulative result of detailed investigation of mist characteristic, laboratory studies of fibre and surface treatments. Both Begg Cousland and Evergreen have over 25 years experience in the design, manufacturing and installation of Candle Filter Elements.

CONSTRUCTION

The unit consists of fibres packed between a pair of concentric screens. Both screens are made of suitable corrosion resistant materials. Type, orientation, fibre bed depth and acking density are tailored to the needs of specific applications.

PRINCIPLE

Coarse mist particles are removed by impaction and direct interception. Finer particles are whisked away through Brownian diffusion. These particles coalesce into a liquid film which is forced by gas flow downstream of the fibre bed. The liquid then flows by gravity into the drain.

APPLICATIONS

The EVERFIBRE Bed Mist Eliminator is designed to rid air/gases of emissions which could harm human and plant life, affect downstream equipment and cause plume opacity. The world is concerned about an endangered environment and for industries conscious about an endangered
environment and for industries conscious of the perils of pollution, the EVERFIBRE Bed Mist Eliminator is a viable solution to a vexing problem.

The EVERFIBRE Bed Mist Eliminator finds wide application in the field of sulphuric acid, sulphonation plants, chlorine plants, nitric acid and ammonium nitrate plants and compressed gas applications.

Today, hundreds of these mist eliminators are helping to clear the air in process plants through out the world. Plant managers report that these devices are working satisfactorily and our experienced technical cell has successfully carried out a number of field trials at customer locations.

INSTALLATION CONFIGURATIONS

Two possible installation configurations are available.

1. Standard flange forward flow (SFFF) in which the element hangs from a tubesheet. In this option, the mist laden gases flow from outside the element and clean gas exists through the inner center core. This installation features ease of installation and maintenance. The High Efficiency elements are recommended in this configuration.
2. Reverse-flow upside down (RFUSD) in which the mist eliminator is placed vertically on a tubesheet. In this option, the mist laden gases flow from inside the central core of the element and the clean gas exists through the outside. This installation will result in reduction of housing vessel size. Both the HE HFseries mist eliminators are available in this con-figuration. However due to exit velocity reentrainment consideration The High Throughput elements are recommended only in this configuration.
