Tray column and packed column widespread use in chemical, petrochemical and other industries to separate liquid mixtures. Today, high efficiency of mass transfer is one of key factors influencing the choice of column type. Our company proposes additional increasing mass transfer efficiency by placement structured packing between distillation trays.
Most efficient using of the structured packing is achieved in a flooded her condition, in the mode of emulsification. In this case, increases the mass transfer area and the volumetric mass transfer coefficient is 2-3 times. Cyclic distillation technology is able to raise efficiency of mass transfer due to the location structured packing between the Maleta trays. For cyclic distillation there is no fluid motion at the tray, as result we have effect of partitioning the bubble layer by height.
· Possibility to set structured packing between the trays (including a fluidized layer);
· The increase in the volume mass transfer coefficient is 2-3 times;
· Partition bubbling layer on height.
Cyclic distillation technology gives opportunities to combine all the advantages of tray and packed column.
