The Vane liquid collector is used in towers that process high vapor loads and low liquid loads (vacuum service). The vane blades collect the overhead liquid and direct it into an annular sump, which may then be drawn from the tower or fed to a distributor below using an appropriate feeding system. It offers minimal pressure drop and it can provide open areas from 40-75%. It also minimizes entrainment, even at high vapor rates as is common with traditional gas risers in this type of service.
The vanes rest on an annular sump, and are fastened to clips provided on the sump.The sump is welded to the tower wall and is generally supplied by the column vendor as a tower attachment. For larger towers and high liquid rates, one or more collection troughs are added, spanning across the annular sump to reduce liquid gradients.
Applications
It is widely used in packed extraction tower, absorption tower and cooling tower, and it is an ideal choice for separation, mixture or handling of vapor-liquid load, suspensions, emulsions, fouling or contaminated liquids. It is also used in frequently pressure and pressure vacuum operations of distillation, absorption, extraction and other processes.
