## Abstract

An aerosol separator is arranged before a CO2 compressor to prevent wear and damage in CO2 recovery systems for the recovery of CO2 arising during fermentation using a compressor.

## Claims

### Claim 1

System for the recovery of CO2 arising during fermentation with a CO2 compressor (19), characterised in that an aerosol separator (1) is arranged before the CO2 compressor (19).

### Claim 2 (depends on 1)

CO2 recovery system according to claim 1, characterised In that the aerosol separator (1) comprises a watering device (3).

### Claim 3 (depends on 2)

CO2 recovery system according to claim 2, characterised In that the watering device (3) comprises at least one nozzle.

### Claim 4 (depends on 1, 2, 3)

CO2 recovery system according to at least one of the claims 1 to 3, characterised in that the aerosol separator (1) comprises at least one flat separation element (2) through which the aerosol-loaded CO2 gas flows.

### Claim 5 (depends on 2, 3, 4)

CO2 recovery system according to one of the claims 2 to 4, characterised in that the watering device (3) waters the at least one separation element (2).

### Claim 6 (depends on 1, 2, 3, 4, 5)

CO2 recovery system according to at least one of the claims 1 to 5, characterised in that a gas washer (4) is arranged before the aerosol separator (1).

### Claim 7 (depends on 1, 2, 3, 4, 5, 6)

CO2 recovery system according to at least one of the claims 1 to 6, characterised in that a CO2 gas balloon (11) is arranged between the aerosol separator and the CO2 compressor (19).

### Claim 8

Method of recovering CO2 arising from the fermentation, characterised in that the aerosol-loaded CO2 gas is fed to an aerosol separator (1) before being compressed.

### Claim 9 (depends on 8)

Method according to claim 8, characterised in that the aerosol-loaded CO2 or the at least one separation element (2) is watered during the aerosol separation.

### Claim 10 (depends on 8, 9)

Method according to one of the claims 8 or 9, characterised in that the CO2 gas loaded with the aerosol is passed through a gas washer (4) before the aerosol separation.

### Claim 11 (depends on 8, 9, 10)

Method according to one of the claims 8 to 10, characterised in that the CO2 gas is passed to a CO2 balloon before being compressed.

### Claim 12

Use of an aerosol separator before a CO2 compressor in the recovery of CO2 arising from fermentation.
