摘要： A LNG liquefaction plant system includes concurrent power production, wherein the refrigeration content of the refrigerant or SMR is used to liquefy and sub-cool a natural gas stream in a cold box or cryogenic exchanger. For concurrent power production, the system uses waste heat from refrigerant compression to vaporize and superheat a waste heat working fluid that in turn drives a compressor for refrigerant compression. The refrigerant may be an external SMR or an internal LNG refrigerant working fluid expanded and compressed by a twin compander arrangement.

摘要： Methods and systems for treating a compressed gas stream. The compressed gas stream is cooled and liquids are removed therefrom to form a dry gas stream, which is chilled in a first heat exchanger. Liquids are separated therefrom, thereby producing a cold vapor stream and a liquids stream. A first part of the cold vapor stream is expanded to produce a cold two-phase fluid stream, and a second part of the cold vapor stream is cooled to form a cooled reflux stream. Various streams are fed into a separation column to produce a cold fuel gas stream and a low temperature liquids stream. The second part of the cold vapor stream is cooled by the cold fuel gas stream, which becomes a warmed fuel gas stream that is compressed and used with the low-temperature liquids stream to chill the dry gas stream and to cool the compressed gas stream.

摘要： The invention relates to a method for condensing a carbon dioxide-rich gas stream, wherein a stream of water heated by an exchange of heat with the carbon dioxide-rich stream, which is at least partially condensed, is sent to at least one compressor (3,21) for compressing the carbon dioxide-rich stream or a fluid, the carbon dioxide-rich stream of which is derived, in order to at least partially cool at least one stage of said compressor.

摘要： The invention relates to a method and also a device for producing a gas product, wherein a first gas stream is combined with a second gas stream and the first gas stream that is present at a lower output pressure than the second gas stream is fed to a mechanical compressor in order to be compressed to the preset pressure of the gas product. It is characteristic in this case that the pressure of the first gas stream is elevated using a gas jet compressor arranged upstream of the mechanical compressor, to which gas jet compressor at least a part of the second gas stream is fed as pumping medium.
