Abstract

See full text

A method and a control system are provided for reducing the size and/or the frequency of hydrodynamic slugging in a fluid processing system. The fluid processing system includes a pipeline for conveying produced fluids and a vessel for receiving the produced fluids from the pipeline. A control valve is provided in the pipeline upstream of the vessel. A pressure sensor is provided upstream of the control valve. Pressure information from the pressure sensor is sent to a master control loop in a cascade control scheme in which the master control loop controls a slave control loop which in turn controls the control valve. The master control loop determines a set point of the slave control loop coupled to the control valve to achieve a pressure setpoint. The slave control loop, also referred to as a pseudo-flow controller, determines whether the control valve opening needs be modulated to achieve the setpoint of the slave control loop. A method is also provided for retrofitting an existing fluid processing system.
