Baffles separators

Baffle separators of the Venetian blind, V, W, and wave types are widely used for spray removal. They have small space requirements and low pressure drops. They operate by diverting the gas stream and ejecting the droplets onto the collector baffles. Efficiencies of single stages may be only 40-60%, but by adding multiple stages, efficiencies approaching 100% may be obtained. 

Vj is calculated based on Figure 1, which uses, as the critical level," a height of one inch above the lower end of the drum baffle separating the risers from the downcomers.

Keeping the liquid level constant is important. Installing a preferential baffle in the column bottom compartment (Sec. 4.5) heis been recommended (178, 357). This baffle separates the bottom and reboiler sumps and ensures a constant head to the reboiler. 

Polymer films and shells are widely applicable in separating baffles of sealing devices. Pol3miers are also preferable as materials for membranes and flexible baffles separating unlike or differently loaded media intended for the conversion of pressure into motion or vice versa. The membranes should meet the requirements of high deformability, chemical resistance and perfect sealing properties.

The oil, emulsion, and water enter the vessel and must follow the long flow path between the baffles. Separation takes place in the straight flow areas between the baffles. Turbulence coupled with high flow velocities prevents separation at the corners, where the flow reverses direction. Tracer studies indicate that approximately two thirds of the plan area of the tank is effective in oil-water separation.
