Begg Cousland is a historic reference in gas-liquid separation and mist control, with a track record dating back to the nineteenth century and consolidated specialisation in mist elimination for demanding industrial processes. The company has built an international reputation based on the design and manufacture of mesh pad demisters, coalescers and fibre bed candle filters, with the ability to adapt the filter medium and equipment configuration to the hydraulic regime and nature of the contaminant. This combination of experience, applied design and manufacturing control makes Begg Cousland a very solid specialist when the objective is to protect downstream equipment, reduce emissions and recover product with high reliability.
Within this range, BECOIL demisters and BECONE coalescers cover the separation of entrained droplets and fine mists by impaction and coalescence, while BECOFIL candle filters are designed for the removal of very fine mists, even below 2 microns, combining impaction, coalescence and Brownian diffusion according to particle size and gas velocity.
Begg Cousland also offers different fibre materials — glass, carbon, polypropylene, polyester or PTFE — and high-velocity, low-pressure-drop or high-efficiency configurations, allowing each solution to be adapted to space limitations, admissible pressure drop and real capture objective.
One of the areas where this specialisation is most valuable is sulphuric acid plants. Begg Cousland is distinguished by its specific knowledge of critical points such as the drying tower, inter-pass absorption tower and final absorption tower, and its ability to select demisters, coalescers and candle filters based on plant type, mist generation mechanism and the combination of required efficiency, velocity and pressure drop. This is complemented by experience in complementary gas cleaning technologies, such as Becoflex, a rotary brush scrubber designed to impact and wet particles or contaminants at high speed.
Overall, Begg Cousland understands mist separation as a process discipline with a direct impact on emissions, product recovery, asset protection and operational continuity.
