The horizontal separator vessel is one of the most important parts of the separation train. CFD can be used to develop an improved understanding of the flow within this vessel and the way in which the flow interacts with the internals. The flow detail provided by CFD enables the position and spacing of the baffles to be optimised.

In this example, the flow enters the vessel through four inlet cyclones, and is then calmed and distributed by consecutive baffles. The path lines of the predicted flow are seen to align with the vessel walls, and are similarly coloured, implying that uniform flow conditions have been produced. These are the optimum conditions for the separation of liquid droplets by gravity.

Downstream of the Plate Pack Coalescer, the pathlines (coloured by velocity) show that smooth flow exists in the liquid phase. This is the optimal flow for separating oil from water, water from oil and gas bubbles from these two liquids.
