Factors Influencing the Work Efficiency of Mesh Type Demister Pads

Wire diameter is an important factor in manufacturing materials because it will directly affects flow, dirt holding capacity, pressure drop and cost. Knitted wire mesh demister pad is used to separate in the most efficient manner the very fine enstrained drops carried away by a gas or steam, either at a boiling stage, vacuum evaporation or bubbling of a liquid. In fact there are two phenomena, one mechanical and one physical, but no filtration at all since the size of the held drops has no realtion with the infinitely greater size of the pore or open space. The head loss or gas passage resistance is practically imperceptible, however demisting can reach up to 99% efficiency. Speed of the gas or steam is another factor that conduct influence to the efficiency of the demisters: A demister reaches the highest efficiency when the speed of a gas or steam ranges between certain limits.
