Coalescers remove liquids from a gas stream with a single coalescing stage of elements. The flow enters the vessel below the elements and passes through a flow distributor. This acts as a primary separation device removing coarse liquids by gravity. The flow passes through the coalescing cartridges in an inside-to-out flow direction. Liquids are coalesced through the structure of the element. These then settle by gravity and can be drained from the vessel.
