Abstract: A process control system for use in an oil and/or gas production and/or transportation system, comprises a controller configured to receive an input signal comprising measurement data relating to a production fluid flow in an oil and/or gas production and/or transportation system. The controller is configured to determine from the received input signal an adjustment in the configuration of a flow control arrangement of the production, and provide an output signal indicative of the adjustment in the configuration of the flow control arrangement. The system is configured to mitigate the formation of gas hydrates and/or the accumulation of paraffin wax, asphaltenes or other solids in an oil and/or gas production and/or transportation system by adjusting the flow control arrangement to vary the injection of a chemical into the production and/or transportation system.
