The carry-over of liquid particulate matter by gas or vapour is generally termed as ‘entrainment’, which is commonly encountered in gas-liquid separations. The Demister Pad is an entrainment eliminator manufactured by HAST. It is specially designed and fabricated from knitted wire of metallic or synthetic materials, to suit specific process configuration in existing or new equipment. When properly installed, the Demister Pad achieves 99.9% + separation efficiency with minimal pressure drop.
