| Zusammenfassung: | The utility model discloses a 2-MD decomposition system which comprises a stripping tower, gas stripping tail gas enriched at the top of the stripping tower sequentially passes through a primary condenser and a secondary condenser and is conveyed to a condensate collecting tank, and the condensate collecting tank is connected with the middle part of an acetaldehyde rectifying tower through a condensate conveying pump; acetaldehyde steam enriched at the top of the acetaldehyde rectifying tower is conveyed to the two acetaldehyde intermediate tanks through a tower top condenser, an acetaldehyde return tank and an acetaldehyde conveying pump in sequence; the two acetaldehyde intermediate tanks are respectively connected with an acetaldehyde storage tank through pipelines; a first heating medium coil pipe is arranged at the tower bottom of the acetaldehyde rectifying tower; compared with the traditional 2-MD decomposition system, the 2-MD decomposition system disclosed by the utility model has the advantages that |
