Publication number: 20120063982Abstract: The laughing-gas-containing gas (1) is diluted by means of a diluting gas (2). The diluting gas (2) is virtually free from water fractions in the dryer (3). After feed of the diluting gas (2) via the feed line (13), exhaust gas (8) from the catalytic decomposition (7) is added (4) to the laughing-gas-containing feed gas (12). After addition (4) of the exhaust gas (8) from the catalytic decomposition of laughing gas (7), the laughing-gas-containing feed gas (12) is compressed (5) and passed to the heat exchanger (6). In the heat exchanger (6) the laughing-gas-containing feed gas (12) is preheated by heat exchange with the exhaust gas (8). The exhaust gas (8) is cooled in the heat exchanger (6) in this process. The preheated laughing-gas-containing feed gas (12) is passed via a further optional heater (11) as a feed to the catalytic laughing gas decomposition (7).
