Abstract (en)
[origin: EP1892457A1] The method involves separating compressed fuel gas into partial gas flows (A, B) by a separating device (1). The partial flow (A) is heated by a heat exchanger (5) such that the flow has temperature greater or equal to 8 degree Celsius after expansion of the flow (A) in a work machine (2) e.g. expansion turbine. The flow (B) is compressed by a compressor (3) driven by the machine, and the compressed flow (B) is cooled such that more than 50 percentages of the flow (B) is accumulated in a liquid condition. The liquefied fuel gas (Bf) is stored in a heat insulated reservoir (14). An independent claim is also included for a device for storing fuel gas, comprising a separating device.
