Abstract: An arrangement for liquefying natural gas is provided. The arrangement includes a gas turbine unit that includes a gas turbine compressor, a steam turbine unit, a first compressor unit, a shiftable clutch, a heated steam generator for supplying steam to the steam turbine unit, and a second compressor unit. The steam turbine unit and the first compressor unit have a common, rigidly connected first shaft assembly, while the gas turbine unit and the second compressor unit have a common, rigidly connected second shaft assembly. In order to increase economic efficiency, the first shaft assembly and the second shaft assembly are operable to be connected to and disconnected from each other using the clutch. A suitable method for starting said arrangement is also provided.

Abstract: A turbo compressor train is provided. The turbo compressor train includes a turbo compressor unit and a drive assembly for driving the turbo compressor unit. The drive unit has a gas turbine and a generator and a steam turbine. The steam turbine may be coupled together with the generator to the turbo compressor unit and the gas turbine by means of a coupling device. The coupling device has an overrun coupling and a coupling exciter with which the overrun coupling may be taken from a disengaged condition to an active condition by engaging of the overrun coupling at synchronous speed of the gas turbine and the steam turbine and if the overrun coupling is engaged, disengages upon a speed increase to the steam turbine and generator so that the generator may be driven by the steam turbine at a higher speed than the turbocompressor unit by the gas turbine.

Abstract: A compressor plant with at least one gas turbine having a gas turbine compressor and with a steam turbine is disclosed, wherein a steam generation plant which is assigned to the gas turbine is operated with exhaust gases of the gas turbine, such that the steam generated in the steam generation plant drives the stream turbine. There is assigned at least one additional compressor for compressing a process medium. The compressor is connected directly to the gas turbine and/or the steam turbine such that the assigned compressor is driven in each case directly by the gas turbine and/or the steam turbine.
