Patent ID: 8591626

Claim:
A method for separation of a gas mixture ( 1 ) that contains carbon dioxide, said method comprising: separating carbon dioxide from a carbon dioxide-containing gas mixture ( 1 ) by physical gas scrubbing (W 1 ) to produce two product streams ( 3 , 4 ) that contain primarily carbon dioxide and have different pressures, and in an event of an operational breakdown, the pressures of the two carbon dioxide product streams are balanced, and said carbon dioxide product streams are subjected to an after-treatment step (W 2 ) and then released into the atmosphere, wherein to balance the pressures of the two carbon dioxide product streams ( 3 , 4 ), the lower pressure carbon dioxide product stream ( 3 , 7 ) is compressed by means of a gas jet ventilator (G), and the higher pressure carbon dioxide product stream ( 4 ) is used as a pumping medium ( 6 ) in the gas jet ventilator (G).
