Mist Eliminators

The separation action of a classifier is mainly that of impingement. The vapour passes easily through large free volume of knitted mesh elements but entrained liquid droplets with greater inertia contact the extensive wire surface of elements and are briefly held. These droplets flow downwards collecting on adjacent wires, flowing downwards again when these collecting points are overloaded. The drops grow in size until they are large enough for the force of gravity to exceed the combined forces of velocity and surface tension when they fall down. The resultant stream is pure vapour containing no liquid.

The highly efficient method of entrainment separation by employing classifiers is widely used in  liquid gas process operations in petroleum refining, chemical distillation and evaporation, distillation plants and nuclear power plants. The important vessels where classifiers are fitted are distillation columns, vacuum towers, fractionating towers, lube oil towers, flash drums, knock-out drums, steam drums, scrubbers, strippers, absorbers, evaporators, cooling towers.

• It is a highly efficient entrainment separator at velocities which can vary 8-10 times.
• It has no moving parts and does not require operating attention.
• It is automatic in its operation. No auxiliaries are needed - no instrumentation; once instilled it work.
• It is inexpensive to purchase and easy to install.
• It combines very high efficiency with very low pressure drop.
• Is has no operating costs other than periodic replacement after an extended period of operation.
• It can be made from a wide variety of materials to suit any unusual process or corrosive condition.
• It reduces solvent and product losses.
• It is self cleaning because of the scrubbing action of the coalesced droplets.
• It can be designed for operation at high efficiency even during violent surging conditions.
• It pays for itself in a very short time because of its high efficiency and low cost
