One exemplary embodiment can be a vessel. The vessel can include a body, an inlet, and an impermeable impingement plate. The body may include a substantially cylindrical structure orientated substantially horizontally, and first and second heads coupled at opposing ends of the substantially cylindrical structure. Generally, the body forms an interior space, and a lower portion of the body forms a trough having a length and a width. The inlet can communicate with the interior space of the vessel. Typically, the impermeable impingement plate has an impingement surface. The impermeable impingement plate may have a first side and a second side extending substantially the length of the trough. The first and second sides may be substantially parallel and spaced apart across at least a portion of the width of the trough.
