Abstract
The invention relates to a method and to a device for condensing CO2 or CO2 separation. According to the invention the thermoacoustic effect is used, with the aid of waste heat from a power station, to produce power for a compressor for compressing a working medium, in particular for compressing a CO2-containing flue gas, and/or for cooling the working medium.
Claims19
1-18. (canceled)
A method for condensing a working medium of a power station, comprising:
- producing a power to a compressor by a first thermoacoustic machine;
- compressing the working medium by the compressor;
- generating a cold to a cooling device by a second thermoacoustic machine;
- and
- cooling the compressed working medium in the cooling device.

A device for condensing a working medium of a power station, comprising:
- a compressor that compresses the working medium;
- a cooling device that cools the compressed working medium;
- a first thermoacoustic machine that produces a power to the compressor for compressing the working medium;
- and
- a second thermoacoustic machine that produces a cold to the cooling device for cooling the compressed working medium.
2 more elements
A device for CO2 separation of a working medium of a power station, comprising:
- a compressor that compresses the working medium;
- a cooling device that cools the compressed working medium;
- a first thermoacoustic machine that produces a power to the compressor for compressing the working medium;
- a second thermoacoustic machine that produces a cold to the cooling device for cooling the compressed working medium to a liquefied working medium;
- and
- a separator that separates the liquefied working medium into liquid CO2 and a residual medium low in CO2.
