Are there any specific requirements regarding separation/removal efficiency?
Separation or removal efficiency targets may be set by statutory emission requirements or a need to reduce a certain amount of contaminants in order to avoid corrosion and other damage downstream in the process. In some processes, droplet separators are used to reuse valuable substances and product.
Separation efficiency specifies the degree of liquid and particles the droplet separator removes from the gas flow. Separation efficiency is calculated using a number of variables, including type of droplet separator (mist eliminator), gas and liquid density, gas flow velocity and amount of liquid.
An increased gas flow rate leads to increased separation efficiency, but it also means an increase in pressure drop. It is important to consider the trade-off between level of separation efficiency and total operating cost.
