A turbine analysis device according to the present application includes a state quantity acquiring unit configured to acquire a state quantity of a turbine, the state quantity including a temperature of the turbine. A load specifying unit specifies a history of a load of the turbine, based on the state quantity. A load and time calculating unit calculates a relationship between the load of the turbine and an operable time when the turbine is operated at the load, based on a designed service life of the turbine and on a history of the load that has been specified by the load specifying unit.

Systems and methods are provided for combined cycle power generation and enhanced hydrocarbon production where emission gases during power generation are separated by adsorption and applied to facilitate extraction of hydrocarbons from a reservoir. A power generation plant passes exhaust gas to a first swing adsorption reactor. The first swing adsorption reactor adsorbs the CO.sub.2 from the exhaust gas. An adsorption cycle of the first swing adsorption reactor is variable. An injection well injects the CO.sub.2 adsorbed by the first swing adsorption reactor in a hydrocarbon reservoir. A production well that is in communication with the injection well produces a mixture of hydrocarbons and CO.sub.2. A second swing adsorption reactor purifies the produced hydrocarbons by adsorbing the produced CO.sub.2 from the production well.

A flow guiding appliance of a turbomachine, in particular of an aircraft engine, for a partial exit flow of an outlet guide vane of a compressor, wherein, a flow guiding element delimits an annular channel about a shaft of the turbomachine. A frictional engagement connecting surface at the circumference of the flow guiding element connects the flow guiding element to another structural component of the turbomachine. The frictional engagement connecting surface with a closed enveloping surface can be inserted in a deformed state into the structural component with a circular cylindrical sealing surface with at least two opposite points. The at least two points of the closed enveloping surface are arranged in at least two opposite frictionally engaged contact areas of the circular cylindrical sealing surface following deformation. The invention also relates to a method for creating a flow guiding element.

The present invention provides a moisture separator separating condensed water mist in compressed air, and an air cycle system provided with the same. The moisture separator includes a coalescer filter and a wire mesh pad demister. The coalescer filter is provided with a filter media formed of a fiber layer through which compressed air is passed, primarily condensing moisture mist in the compressed air, and filtering foreign particles and a housing supporting the filter media. The wire mesh pad demister is provided at a downstream of the coalescer filter to receive the compressed air passed through the coalescer filter and secondarily condenses moisture mist in the compressed air to separate moisture using gravity.
