热泵精馏隔壁塔分离宽沸程物系的模拟
Simulation of vapor recompression assisted dividing wall column for wide boiling mixture separation
摘要
Abstract
Bigtemperature difference between the overhead and bottom of the dividing wall column (DWC) limited the application of vapor recompression technology into DWC for separating wide boiling mixture, so the DWC with vapor recompression at side product stage scheme is investigated in this paper. With the aid of CGCC profiles, the phase of stream withdrawn from side product stage can be determined, and the corresponding VRC assisted DWC schemes can be achieved. Simulation results for wide boiling mixture separation show that the proposed schemes have high energy efficiency under large vapor and liquid flow rate in the main column.关键词
