Abstract: A method for operating a pipeline system includes obtaining sensor data of a gas in the pipeline system from sensors of a sensing unit. The method also includes performing a real-time and closed loop control scheme using the sensor data and a material model of the gas to determine one or more control decisions. The method also includes operating one or more controllable pipeline elements to adjust a temperature, a pressure, a flow rate, or a composition of the gas according to the one or more control decisions.

Abstract: A method for optimizing a pipeline includes determining a mode of optimization and operation for the pipeline. The method also includes obtaining an objective function quantifying a performance variable as a function of one or more control decisions of the pipeline over a future time horizon. The method includes optimizing the objective function subject to one or more constraints to determine control decisions for the pipeline that result in an optimal value of the performance variable. The method includes operating equipment of the pipeline according to the control decisions.
