| Abstract: |
| Chemical software was used for the process simulation and parameters optimization of the vent gas absorption system in extraction plant. The results indicated that the stripper temperature, stripper top tray pressure and live steam flow rate influenced the stripping effect, thus influenced the absorption of the vent gas. With the stripper temperature rising, the stripper top tray pressure decreasing and the live steam flow rate inecreasing，the residual solvents in vent gas reduced. In the process of manufacture, controlling the stripper temperature above 105?℃, the least live steam flow rate was 110 kg/h for ordinary pressure (100 kPa) stripping, and the least live steam flow rate was 65 kg/h for negative pressure (60 kPa) stripping in 1 000 t/d oil extraction plant. |
