| Abstract: | The recovery column in acetonitrile extraction butadiene unit has been used for many years. With the expanding of production capacity, the downcomer is fouled resulted from the column structure. Moreover, fewer plate number and low perforation area lead to low acetonitrile recovery rate and treatment capacity. Few fouling occurs after the revamp, which increases the acetonitrile recovery rate and treatment ability. |
