Abstract
Disclosed are coalescing media for coalescing a mixture of two phases, namely a continuous phase and a dispersed phase. The disclosed coalescing media has multiple layers with distinct porosities, where an interior layer of the coalescing media has a higher porosity than the layers immediately adjacent to the interior layer. The disclosed media may be utilized in coalescers, coalescing systems, or coalescing methods for removing the dispersed phase from the mixture.
