    Abstract: A cryogenic liquid expansion turbine has a turbine wheel mounted on a rotary shaft, at least one radial inlet for cryogenic liquid to be expanded in the expansion turbine for the rotary shaft, and a dry gas sealing means at a position along the rotary shaft between the turbine wheel and the bearings. There is a thermal barrier member between the turbine wheel and the dry gas sealing means, a gas chamber on the dry gas sealing means side of the thermal barrier member, and an internal passage for cryogenic gas to the said gas chamber. A method is also provided.

    Abstract: A gaseous hydrocarbon stream (10) is cooled to produce a liquefied hydrocarbon stream (20). The gaseous hydrocarbon stream (10) is cooled in one or more heat exchangers (140a) using a first refrigerant from a first refrigerant circuit (100) in which said first refrigerant is compressed in a first compressor (110) driven by a first gas turbine (120) having a first inlet air stream (125) and liquefied using a second refrigerant circuit (200) wherein a second refrigerant is compressed in a second compressor (210) driven by a second gas turbine (220) and having a second inlet air stream (225). The cooling duty available in a stream of a chilled coolant (320) is divided over at least first (340) and second (350) parts in accordance with a common input parameter, and one or both of said first and second inlet air streams (125, 225) are cooled with the chilled coolant (320), whereby the cooling duty available in the first part (340) is used to cool the first inlet air stream (125), and the cooling duty available in the second part (350) is used to cool the second inlet air stream (225).

    Abstract: Systems and methods for storing and releasing energy comprising directing inlet air into a vertical cold flue assembly, a portion of moisture being removed from the air within the cold flue assembly. The air is directed out of the cold flue assembly and compressed. The remaining moisture is substantially removed and the carbon dioxide is removed from the air by adsorption. The air is cooled in a main heat exchanger such that it is substantially liquefied using refrigerant loop air. The substantially liquefied air is directed to a storage apparatus. The refrigerant loop air is cooled by a mechanical chiller and by a plurality of refrigerant loop air expanders. In energy release mode, working loop fluid warms the released liquid air such that the released liquid air is substantially vaporized, and the released liquid air cools the working loop fluid such that the working loop fluid is substantially liquefied. A portion of the released liquid air is directed to the at least one generator and used as bearing air lor the at least one generator. The substantially vaporized air is directed to a combustion chamber and combusted with a fuel stream. Combustion gas may be directed from the combustion chamber to at least one expander, the expanded combustion gas split into two portions. The first portion may be directed to a first heat exchanger, and the second portion may be directed to a second heat exchanger such that the second portion heats and substantially vaporizes the released liquid air.
