[0033] like figure 2 As shown, the raw material 4 is taken from the pre-de-weighting tower and the de-weighting tower of the C5 separation device of a certain factory, and it is introduced into the decarbonization five-column. The main composition is: n-pentane 0.7 %, cis, trans-2-pentene 1.2%, isoprene 0.7%, cyclopentene 8.7%, piperylene 32.8%, cyclopentadiene 2.9%, dicyclopentadiene 36.3%, carbon six 14.5% %, polymer 2.2%, the flow rate is 13000kg / h. The material is introduced into the five decarburization tower 1, the number of five decarburization towers is 42, feed from 24 plates, the pressure at the top of the tower is 0.12MPa, the temperature at the top of the tower is 47°C, the pressure at the bottom of the tower is 0.14MPa, the temperature at the bottom of the tower is 106°C, The reflux ratio is 1.8. The top extraction 5 is mixed with the azeotropic stream 6, and the flow ratio of the stream 5 and the stream 6 is 0.1, and is introduced into the piperylene column 2. ...
