    Abstract: The present invention relates to control of engine variable of a gas turbine engine to regulate the surge margins of at least two compressors. A controller (20) receives data measured from engine sensors (22, 23) and uses said data to determine an indication of surge margin for each of at least two compressors (6, 7) of the gas turbine engine. The controller (20) uses the indications of surge margin for each of the compressors to determine a control strategy that balances the requirements of each compressor. In one embodiment a surge margin operating map divided into different control domains (40, 43, 43) is used. The indication of surge margin determined for each compressor is plotted to determine which control domains the current operating point on the surge margin operating map falls within. The invention is particularly suited to control binary bleed valves associated with the compressors and the position of the current operating point in a control domain and/or the time spent in the operating domain can be used to determine how many of the binary valves should be opened or closed.

    Abstract: An industrial system for compressing a waste gas product, such as CO2, including a compressor train having an upstream rotor portion and a downstream rotor portion arranged in flow series with said upstream portion. Each rotor portion includes one or more compressor stages and said downstream portion is arranged to rotate at a variable relative speed to that of the upstream rotor portion. Sensing equipment for the compressor train is arranged to determine one or more flow conditions and a controller is arranged to receive data indicative of said one or more sensed flow conditions. The controller is arranged to set the rotational speed of the upstream rotor portion based upon the pressure or flow rate of gas upstream of said compressor train and to set operational parameters for said downstream portion so as to maintain a desired surge margin for said upstream rotor portion.

    Abstract: Method and apparatus for controlling one or more first compressors (12), through which a compressor feed stream (10) is passed. At least one throttling valve (32) is provided downstream of a compressor recycle line (22), which is provided around the or each first compressor (12) and includes an in-line first recycle valve (24). Sometimes, at least a fraction of the compressor feed stream (10) is selectively allowed to bypass the or each first compressor (12) and the at least one throttling valve, via a bypass line (60). At least one of the throttling valves (32) is automatically controlled using the measurement values of at least one pressure and at least one flow of the group consisting of: the pressure (P1) of the compressor feed stream (10), the flow (F1) of the compressor feed stream (10), the pressure (P2) of the first compressed stream (20) and the flow (F2) of the first compressed stream (20). A first compressor controlled this way may be used in a method of cooling an initial hydrocarbon stream (100).
