| titleOfInvention | Process for purifying a recycle stream from an installation processing 1,3-butadiene |
| abstract | The recycle stream (1) is purified in stripping column (K1) for prepurification of two substreams, namely pure 1,3-butadiene feed stream (2), and is purified pure 1,3-butadiene feed stream (2) A first substream (3) for obtaining a first purified recycle stream (4) comprising together, and also a second substream which is purified in an extractive distillation plant by extractive distillation using an optional solvent (6) 5) wherein the extractive distillation plant comprises a main scrubber (K2) and also a gas stripper column (K3) constructed as a concentration column, provided that as much of the quantitative stream as possible is distributed to the first substream (3) , All streams fed to the 1,3-butadiene process plant (A) having a proportion of 1,3-butadiene of at least 90% by weight, based on the sum of the C 4 hydrocarbon weights of all streams fed to the process plant (A). Agreed specification requirements of Disclosed is a process for purifying recycle stream (1) exiting 1,3-butadiene process plant (A), in which the recycle stream (1) is divided in a sustained manner. |
