Example Embodiment
[0044] Example 1
[0045] The number of theoretical plates of the industrial fluorene fractionation tower 9 is 40, the operating pressure at the top of the tower is normal pressure, and the reflux ratio is 6:1. The feed position of the heavy wash oil is the 15th plate, and the flow rate is 732.5kg / h. The acenaphthene fraction extracted from the top of the tower: heavy wash oil = 0.63:1 (mass ratio). After drying, the obtained industrial fluorene product is composed of 97.85% (mass fraction) with a gas chromatography analyzer, and the recovery rate of fluorene oxide is 82.4 %. The load of the tubular heating furnace 7 is 299.2 KW, the steam generation rate of the steam generator 10 is 36 kg / h, and the pressure of the produced steam is 0.4 MPa.

[0046] Example 2
[0047] The number of theoretical plates of the industrial fluorene fractionation tower 9 is 30, the operating pressure at the top of the tower is normal pressure, and the reflux ratio is 7:1. The heavy wash oil feed position is the 18th plate, with a flow rate of 732.5kg / h. The acenaphthene fraction extracted from the top of the tower: heavy wash oil = 0.6:1 (mass ratio). After the fluorene product is dried, the composition is 97.69% (mass fraction) with a gas chromatograph, and the fluorene recovery rate is 87.8%. The load of the tubular heating furnace 7 is 347.4 KW, the steam generation rate of the steam generator 10 is 41 kg / h, and the pressure of the produced steam is 0.4 MPa.
[0048] The energy-saving effect of the present invention is obvious, and the energy-saving measures introduced into the process include two points: one is to use the flue gas of the tube heating furnace to preheat the air to increase the temperature of the air entering the furnace...
