SAND TRAP
The SAND TRAP (SEPARATOR) is used to remove produced solids from the well effluents. In a production test equipment configuration, the sand separator is usually located downstream the choke manifold. The well effluent exits the choke manifold after a pressure drop across the choke and enters the sand separator. Following the inlet to the sand trap, the flow diverter causes the well effluent to flow tangent to the wall of the trap. The fluid spins about the wall of the sand trap, creating a centrifugal force. The centrifugal force causes the solids to separate from the well effluents because of the difference in their densities. Gravitational force causes solids to drop to the bottom of the sand trap. Accumulated solids are removed from the bottom outlet at desired intervals.
Strainers eliminate residual solids still contained in the well effluents on it’s path to the top outlet.
