Abstract

In this paper

an improved crude oil distillation process is presented and simulated by PRO/II. The calculation results indicate that given the heat exchange satisfaction of demand the atmospheric still of the new process can save energy by 18.3%

while maintaining a higher distil-off ratio than the traditional on by 0.9%. Additionally

by applying deep distil-off section to the vacuum column

the distil-off ratio can be raised by 0.46% with the same energy consumption. A heat exchanger network for the new process is designed by threshold method and simulated. The calculation results confirm the former assumption about heat exchange objective and the energy conservation effect of the new process.
