A carbon dioxide compression system is disclosed. The system comprises at as a first compressor stage and a second compressor stage arranged in series, at least one inter-stage heat exchanger arranged to receive a compressed gas containing carbon dioxide flowing from the first compressor stage into the second compressor stage and to remove waste heat from the compressed gas, and an energy conversion unit, wherein at least part of the waste heat is recovered and transformed into mechanical energy.

Heat recovery in carbon dioxide compression and compression and liquefaction systems

A drive system for driving a load, comprising a gas turbine configured and arranged for driving the load, an electric motor/generator electrically connected to an electric power grid, a first load coupling connecting the gas turbine to the load, a second load coupling, connecting the load to the electric motor/generator. The electric motor/generator is adapted to function as a generator for converting excess mechanical power from the gas turbine into electrical power and delivering the electrical power to the electric power grid, and as a motor for supplementing driving power to the load. The drive system comprises furthermore a disconnecting device to reversibly disconnect the load from the gas turbine, so that the load can be driven only by the motor.

Gas turbines in mechanical drive applications and operating methods

Method, retention mechanism and bearing device for retaining at least one pad inside the bearing device. The bearing device includes a ring having at least a retaining head, at least one pad disposed inside the ring and having a bottom recess portion configured to receive the at least a retaining head, the at least one pad being configured to pivot on the at least a retaining head, and a retention mechanism configured to retain the at least one pad within a predetermined volume inside the ring. The retention mechanism is configured to apply a retaining force on the at least one pad, in addition to a force between the retaining head and the at least one pad, where the retaining force acts substantially along a radial direction of the ring, away from a center of the ring.

Bearing device, retention mechanism and method for retaining at least one pad

An integrated high-pressure compression unit for a process fluid that includes at least a first compression device able to compress the process fluid from a essentially gaseous initial thermodynamic state to an intermediate thermodynamic state, a second compression device connected mechanically to the first compression device and able to compress the process fluid from the intermediate thermodynamic state to a final thermodynamic state, a motor device able to drive the first compression device and the second compression device, and a pressure casing or housing in which at least the said first and second compression devices are mechanically coupled to each other.
