摘要： Controlling flow of gas in a gas pipeline network, wherein flow of gas within each of the pipeline segments is associated with a direction (positive or negative). Processors calculate minimum and maximum production rates (bounds) at the gas production plant to satisfy an energy consumption constraint over a period of time. The production rate bounds are used to calculate minimum and maximum signed flow rates (bounds) for each pipeline segment. A nonlinear pressure drop relationship is linearized to create a linear pressure drop model for each pipeline segment. A network flow solution is calculated, using the linear pressure drop model, comprising flow rates for each pipeline segment to satisfy demand constraints and pressures for each of a plurality of network nodes over the period of time to satisfy pressure constraints. The network flow solution is associated with control element setpoints used to control one or more control elements.

摘要： A centrifugal compressor 200 used in a gas pipeline 1 has a centrifugal impeller provided with a hub and a plurality of blades. The blade angle distribution of the blade is configured such that a hub side blade angle is maximum on the side closer to a hub side leading edge than a central point of a hub side camber line, and from this part to the hub side leading edge, a hub side blade angle distribution curve is convex in a blade angle increasing direction. Further, the blade angle distribution is configured such that a counter-hub side blade angle is minimum at a counter-hub side leading edge of the counter-hub side camber line, or on the side closer to the counter-hub side leading edge than a central point of a counter-hub side camber line, and in an arbitrary section of the counter-hub side blade angle distribution curve including a part where the blade angle is minimum, the counter-hub side blade angle distribution curve is convex in a small blade angle direction, and in a section from the downstream side of the section where the counter-hub side blade angle distribution curve is convex to the counter-hub side trailing edge, the counter-hub side blade angle distribution curve is convex in a large blade angle direction. With this arrangement, it is possible to obtain a gas pipeline centrifugal compressor in which the low flow-rate side operating range is expanded and a high flow-rate side operating range is maintained.

摘要： A system and method are provided for short term trading in gas and/or gas derivatives. In a preferred embodiment, the system provides a plurality of shallow depth salt gas storage facilities. Each of the facilities is typically operated at pressures in a range close to the pipeline pressure, typically within a range of 20 to 80 bars. If trading results in a difference to be made up, then computers operating the facilities respond quickly to add or remove gas from the pipelines, as required, with a response time as low as two minutes to change the net direction of flow of gas into or out of the storage facilities.

摘要： A method and system for boosting pipeline gas pressure in a low-pressure gas pipeline in which a supplemental gas supply pipe in fluid communication with a supplemental pipeline gas supply is provided to an interior of a gas pipeline containing a pressurized pipeline gas, where the pressure of the supplemental pipeline gas supply is greater than the pressure of the pressurized pipeline gas. The gas pressure differential between the pressurized pipeline gas and the supplemental pipeline gas supply pressure is measured. When the pressure differential reaches a certain predetermined set value, supplemental pipeline gas is provided from the supplemental pipeline gas supply through the supplemental gas supply pipe into a pipeline space between the gas pipeline and the supplemental gas supply pipe. The flow of supplemental pipeline gas is halted upon achievement of a second predetermined set differential pressure.

摘要： A power engine natural gas compressor system to optimize the extraction of natural gas from a reservoir and related gathering systems. The system is controlled by a distributed control system, which is a computer readable program, and allows for humane machine interface allowing for a more efficient use of the available power supply resulting in increased efficiency. Through the use of an integrated control system the present invention achieves a precise control of the overall operation of the system, which would be impossible to achieve through manual manipulation. The system of the present invention is a system capable of multiple functions with minimal losses with respect to efficiency. Different from the compressors found in the market the system uses a sophisticated process and control system, and is constructed and arranged in such a way that someone with little to no training can operate and maintain it
