Abstract
An automated sand separator discharge system includes a sand separator disposed downstream of a wellhead, an inlet conduit for transporting a process stream to the sand separator, a fluid outlet conduit for transporting a liquid and gas stream from the sand separator, a sand discharge conduit for removing sand from the sand separator, first, second, and third valves disposed along the sand discharge conduit, a first transducer connected between the first and second valves and operative to measure pressure in a portion of the sand discharge conduit and to produce a pressure reading, and a control panel operatively connected to the first, second, and third valves and the first transducer, the control panel being programmed to initiate and terminate discharge of sand from the sand separator, and to determine if the first and second valves are sealing completely when closed.
