ABSTRACT:
A separating system is provided for a fluid stream containing oil, water and gas. The fluid stream has a nominal flow rate, a maximum surge flow rate, and a cycle time or period. The system includes upper and lower elongated horizontal vessels. A weir separates the upper vessel into an inlet surge chamber and a liquid over flow chamber. A gas separator is located in the inlet surge chamber of the upper vessel and separates gas from the incoming fluid stream. A gas outlet is defined in the upper vessel. A downcomer tube communicates the inlet surge chamber of the upper vessel with the lower vessel. Oil and water are separated from each other in the lower vessel, which has oil and water outlets defined therein. A liquid overflow drain line communicates the liquid overflow chamber of the upper vessel with the lower vessel. A fluid flow restriction is provided in the downcomer tube such that the nominal flow rate of the inlet stream can flow through the downcomer tube, and such that as the inlet stream flow rate approaches its maximum surge flow rate, liquid will spill over the weir into the liquid overflow chamber where it will temporarily accumulate and then drain down through the overflow drain line into the lower vessel.
