Abstract
Dividing-Wall-Column ( DWC) process is one of the process-enhancing and distillation energy-saving technologies. Compared with the conventional columns, DWC has a special structure leading to a higher thermodynamic efficiency, which is featured by less energy consumption, low investment and fewer equipment for achieving the same separation process. Through the discussion and analysis of the DWC's structure and the analysis of exergy conversion in the distillation process, the DWC's energy-saving principles were elaborated. Taking the separation of toluene-xylene-heavy benzoyl in benzoyl refining process as example, and based on the analysis of ternary system distillation, two kinds of distillation processes were designed: one was the simple direct sequence and the other was a dividing wall column, which were then followed by rigorous calculation and optimization, the result shows that the dividing wall column can save energy by 41. 5% than that of the conventional one,thus leading to fewer equipment and less investment.关键词
