Retrofitting a Side Stream Column Using an Intensified Configuration Combining Heat Pump and Dividing Wall Column |
| 초록 |
Side stream distillation column (SSC), which separates a ternary mixture received much scientific interest associated with a growing industrial demand, is a common energy-intensive process. This study reports the results of a hybrid configuration to retrofit and debottleneck the SSC combining a heat pump and a dividing wall column (DWC). Fractional utilization of the area was used to identify flooding problems in the column as well as how much area is available for vapor flow on an existing stage. The results showed that the proposed sequence can achieve significant operating costs with 83.7% and remove the bottleneck problem. Particularly, a heat pump can improve the performance of DWC, and reversely a DWC can also enhance the energy efficiency of a heat pump and reduce its capital cost.
