Abstract
A downcomer having a screened or otherwise liquid permeable wall is provided for use in a mass transfer or distillation column. The liquid permeable wall provides another avenue for liquid to be removed from the downcomer to increase the liquid handling capacity of the downcomer. When wetted, the liquid permeable wall provides a barrier against vapor entry into the downcomer through the wall.
