Begg Cousland Envirotec have been using worldwide & exclusively distributing in certain countries Benvitec Environment’s BlueFil® meshes, mesh pads & demisters, along with our traditional knitted wire mesh types. BlueFil® is a reliable material and technology in liquid separation processes, air pollution control or to remove particulates from a gas flow.
We use these ‘pyramid-structured’ meshes, with their 3D interlocked monofilament wires in duties where there is a need for a thermoplastic material with a meshpad strength sufficient to resist the operational duty of gasflow, liquid load and, often, soluble or insoluble particulates. The mesh has a very open structure which allows it to handle particulates for a long time before blockage would occur, and which is then quite easy to wash without damage, and re-use.
When used not as a demister mesh, but as a gas scrubber media, the open structure and mesh geometry facilitate the scrubbing process with irrigation sprays co-current or counter-current. Vertically or horizontally installed, the liquid and captured solids will easily flow off the monofilament wires and maintain the benefits of the low pressure loss that BlueFil® offers in all cases.
Examples of our use of BlueFil® are :
Demisting duty at the exit of a chemical process tail gas scrubber
Demisting duty at the end of a cross-flow or vertical gas scrubber in Phosphate and Nitrogen Fertiliser production
Particulate & gas scrubbing stage duties within a cross-flow or vertical gas scrubber in Phosphate and Nitrogen Fertiliser production (e.g. DAP, NPK, CAN & Urea)
