Embodiment 1
[0021] The pre-separation tower, the mesitylene tower and the partial toluene tower all use metal mesh corrugated packing. The thermal coupling process is to realize thermal coupling between the pre-separation tower and the mesitylene tower and the partial toluene tower, as shown in Figure 2. The C9 aromatic hydrocarbon raw material 4 enters the pre-separation tower 1 after heat exchange by the heat exchanger 5, and the pre-separation tower is operated at 30KPa, and the temperature at the top of the tower is controlled at 100°C. The top of the tower is connected to a vacuum device 8, and the gas phase at the top of the tower passes through a condenser 6 Then enter the reflux tank 7, wherein the condensate is partly refluxed, partly as light solvent oil A out of bounds. The pressure of the mesitylene tower is controlled at 100KPa, and the temperature at the top of the tower is controlled above 150°C, so that the gas phase at the top of the tower is used as the heat source of th...

The thermal coupling process is to realize thermal coupling between the pre-separation tower and the mesitylene tower and the partial toluene tower, as shown in Figure 2. The C9 aromatic hydrocarbon raw material 4 enters the pre-separation tower 1 after heat exchange by the heat exchanger 5. The pre-separation tower is operated at 50KPa, and the temperature at the top of the tower is controlled at 130°C. The top of the tower is connected to a vacuum device 8, and the gas phase at the top of the tower passes through a condenser 6 Then enter the reflux tank 7, wherein the condensate is partly refluxed, partly as light solvent oil A out of bounds. The pressure of the mesitylene tower is controlled at 120KPa, and the temperature at the top of the tower is controlled at about 170°C, so that the gas phase at the top of the tower is used as the heat source of the...

The thermal coupling process is to realize thermal coupling between the pre-separation tower and the mesitylene tower and the partial toluene tower, as shown in Figure 2. The C9 aromatic hydrocarbon raw material 4 enters the pre-separation tower 1 after heat exchange by the heat exchanger 5, and the pre-separation tower is operated at 80KPa, and the temperature at the top of the tower is controlled at 160°C. The top of the tower is connected to a vacuum device 8, and the gas phase at the top of the tower passes through a condenser 6 Then enter the reflux tank 7, wherein the condensate is partly refluxed, partly as light solvent oil A out of bounds. The pressure of the mesitylene tower is controlled at 160KPa, and the temperature at the top of the tower is controlled at 185°C, so that the gas phase at the top of the tower is used as the heat source of the r...
