BUTADIENE RECOVERY PROCESS

摘要

The butadiene-rich slops (5) is carried to the flash drum (6), where the initial expanding cause separation vapour (7) from the liquid (8), and separated vapours (7) flow to the distillation column (9), where overhead solvent free concentrated butadiene vapours is obtained and condensed in the water condenser (10) giving the first butadiene stream (11. 1), and the liquid stream (8) flows to the stripping column (12), forming the overhead concentrated butadiene vapour and after it compression the second butadiene stream (11.2) is obtained.
