摘要： 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.

摘要： Methods, devices, and assemblies for controlling pressure in a supply grid are provided. The supply grid is suitable for supplying fluid to loads. The supply grid has first sensors for measuring the flow and/or the pressure of the fluid at first locations in the supply grid and a pump for pumping the fluid or a valve for controlling the flow of the fluid. The method includes: measuring the flow and/or pressure of the fluid at the first locations in the supply grid by the first sensors; predicting the pressure at the second location in the supply grid using a self-learning system based on the measured flows or pressures, wherein the self-learning system is trained to predict the pressure at a specified location in the supply grid; and actuating the pump or the valve at least also based on the pressure predicted by the trained system at the second location.

摘要： A booster-ejector system captures and recycles leakage fluids from a process. When a pressure differential (head) of the process is above a threshold value, an ejector system uses motive fluid from a process high-pressure (HP) region to entrain and compress the leakage fluid, and direct it to a low pressure (LP) region. When the head is below the threshold value, a controller reconfigures a plumbing system and activates a leakage pump to pump the leakage fluid to the LP region. The system can include only one ejector, or a plurality thereof, which can be coupled such that the diffuser output of each ejector is directed to the suction input of the next ejector. At least one of the ejectors can include an exchangeable throat, which can impart a rotational component to the fluid. The HP and LP regions can be the output and input, respectively, of a compressor.
