METHOD, SYSTEM, CONTROLLER AND COMPUTER PROGRAM PRODUCT FOR CONTROLLING THE FLOW OF A MULTIPHASE FLUID |
摘要 |
<p>A method, system, controller and computer program product, for controlling the flow of a multiphase fluid comprising gas and liquid in a conduit, which conduit is provided at a downstream side with a flow restriction and a valve having a variable aperture, which method comprises the steps of selecting a flow parameter of the multiphase fluid in the conduit as a function of a pressure difference over the flow restriction; selecting a setpoint for the flow parameter; allowing the multiphase fluid to flow at a selected setpoint of the aperture of the variable valve; determining the pressure difference over the flow restriction and determining an actual value of the flow parameter from the pressure difference, without using a measurement of another variable in order to determine an actual gas/liquid ratio pertaining to the pressure difference at the flow restriction; controlling the flow of the multiphase fluid by determining a deviation of the flow parameter from its setpoint, determining an updated setpoint for the aperture of the valve which is dependent on the deviation, and manipulating the aperture of the valve accordingly.</p> |
