Abstract: A gas turbine and method are disclosed by which the gas turbine can be safely operated at nominal speed with reduced margin to a surge limit of a compressor. The gas turbine, via a directly driven generator which generates alternating current with an operating frequency and which is connected in a frequency-coupled manner to an electricity grid, can deliver electric power to this grid. In the case of an underfrequency event the compressor of the gas turbine is unloaded by controlled, fast closing of the variable compressor guide vanes (VGV) and as a result maintains a sufficient margin to the surge limit of the compressor.

Abstract: Disclosed is a smokeless cigarette system comprising a reusable cigarette tube and a nicotine stick which can be discarded after use. The nicotine stick comprises a depot filter charged with a nanobead solution and nicotine and flavor substances attached thereto or incorporated therein, and a mouthpiece filter, which are joined together and produced at the factory stage. The disclosed smokeless cigarette is particularly suited for use in non-smoking areas to prevent stress caused by nicotine withdrawal and as a cigarette substitute, but can also be used in different types of cigarettes with varied dosage strengths to ensure gentle nicotine withdrawal and smoke disintoxication. Neither the environment nor other persons are harmed of put at risk by this system by either passive smoking or the generation of odour. The system can be handled in a simple and unproblematic manner since no heat source or heating systems are required.

Abstract: A method is provided for CO2 separation from a combined-cycle power plant with exhaust-gas recirculation and CO2 separation. The hot-gas flow is split into a recirculation flow and an exhaust-gas flow before the final turbine stage in the turbine. A first partial flow remains in the turbine and carries out expansion work in the conventional form, before its waste heat is dissipated, for example in a waste-heat boiler, and the gases are recirculated into the inlet flow of the gas turbine. A second partial flow is diverted before the final turbine stage, and emits its waste heat in an HRSG/heat exchanger, before CO2 is separated from the exhaust-gas flow at an increased pressure level.

Abstract: CO2 compression is a main step in carbon capture and storage, which is essential to control global warming. CO2 compressors are powered by electric motors, which increase operational flexibility but require much energy leading to additional expenses, power and efficiency losses. A method is provided for optimized operation of a plant including a power generation unit with a CO2 capture system and compressor with minimum losses during normal operation, allowing flexible part load. The method allows steam from the power unit to drive a steam turbine, which drives the CO2 compressor via an engaged overrunning clutch if a sufficient amount of steam is available from the power unit, and to drive it by the generator, which is used as motor when insufficient steam is available from the power unit. When no or insufficient steam is available the clutch is disengaged and the steam turbine may be at standstill or idling.
