Begg Cousland - Mist Elimination, Droplet Separation and Gas Scrubbing

Begg Cousland are internationally renowned for their knitted wire mesh demisters and other filters. Begg Cousland specialises in the design and manufacture of mist eliminators; a broad range of wire and fibre form products used for industrial air pollution control and in-process filtration. These cover the spectrum of liquid and fume collection.

Begg Cousland also specialises in the development of gas cleaning technologies and equipment including rotary scrubbers, absorbtion columns and turnkey filtration systems.

KNITTED MESH PADS

Becoil demisting units are impingement type separators consisting of multiple layers of mesh knitted from metal or plastic monofilaments. They have uniform voidage with an extremely high ratio of filament surface area per unit volume of pad.

Becoil demisting units have been specially designed to achieve highly efficiency removal - up to 100% on entrained droplets above 5 microns in size, while generating low pressure losses and are virtually maintenance free.

COALESCER MESHES

To further the collection efficiency below 5 microns, the Becone coalescer was developed. The combined Becone and Becoil installation as a single or double stage arrangement increases collection efficiency to 98% or more in the 2-5 micron range.

LIQUID-LIQUID SEPARATORS

For liquid/liquid separations we offer Becophase plate and knitted mesh coalescers in a wide range of materials. Depending upon the requirement they can be used solely or in combination to separate a wide range of mechanically induced emulsions.

Mono-filament knitted mesh coalescers are best suited for finer separations and lower velocity flow regimes. In water/hydrocarbon separations they are capable of reducing oil concentrations from 500ppm to as low as 15ppm.

Multi-filament knitted mesh coalescers offer an even finer separating ability with certain emulsions. A multi-filament knitted mesh coalescer can separate the same 500ppm of hydrocarbons in water down to as low as 5ppm.

Corrugated plate coalescers are best suited for higher velocity flow regimes, liquids with entrained solids and larger droplet sizes 40 microns and above. Their rugged construction is plug and foul resistant.

CANDLE FILTER MIST ELIMINATORS

Becofil Mist Eliminators, commonly referred to as Candle Filters, are intended primarily for the removal of very fine mist particles of less than 3 microns. Begg Cousland offer a range of filters to conform to the varying requirements of industry in terms of capacity, pressure loss and mist removal efficiency. They help to eliminate visible stack plumes, meet stringent air pollution regulations and recover more lost products from processes.

BECOFLEX ROTARY SCRUBBER / WET DUST REMOVAL

Begg Cousland's specialization in the field of wet gas filtration has found many applications with a need for efficient solid/gas removal. We offer the efficient but simple 'Rotary Scrubbing System' under license. It can be used on its own or in conjunction with a packed bed, atomised spray or with our high efficiency coalescers and mist eliminators.

Odour control and gas scrubbing are ideal uses for Becoflex, whether or not there is a need for simultaneous removal of solids (Becoflex avoids the risk of scrubber packing blocking with solids).

HOT GAS FILTRATION AND CERAMIC FILTERS

Begg Cousland has recently licensed the Caldo technology for hot gas filtration systems and ceramic filters for chemical and other applications such as acid waste incineration, avoiding the cost of cooling the gas first.

Caldo ceramic filter installations are ideal for the abatement of pollution from incineration processes giving:

• Flexibility in the temperature at which gases are treated
• Avoidance of dioxin reformation and pluming of stacks
• Acid gas removal by dry scrubbing with lime or sodium bicarbonate

PACKAGE AND TURNKEY FILTRATION SYSTEMS FOR PLASTICISERS, OLEUM TANKS, ASPHALT AND OTHER VENT GASES

Begg Cousland now have over 70 highly successful turnkey installations of Becofil candle filter mist eliminator systems removing plasticizer oil fumes from exhaust gas from ovens typically curing vinyl coated flooring and wallpaper, synthetic leather and laminated sheets (special films, belts, tarpaulins).

Our method for the removal of these fumes is highly efficient, meeting the lowest emission level requirement in Europe.

Specialised package systems are offered with beneficial designs for filtering contaminants from storage tank vents (Oleum, SO3) or processing materials such as Asphalt.
