[0076] Example 1
[0077] This example is based on figure 1 The flow shown is carried out.
[0078] The Fischer-Tropsch synthesis light distillate stream 1 enters the 1# cutting tower with a theoretical plate number of 35, the reflux ratio is 4, and the feeding position is 19 plates (from top to bottom, the same below), from the 1# cutting tower column At the end get logistic 3 as C 8 + (including C 8 ) fraction, the purity reaches 99.95%, and the recovery rate reaches 99.97%;
[0079] the C 8 + The fraction enters the 2# cutting tower with a theoretical plate number of 35, the reflux ratio is 4, and the feed position is 19 plates, and C can be obtained from the top of the tower. 8 component stream 4;
[0080] C 8 The fraction enters an azeotropic distillation column with a theoretical plate number of 20. In the present embodiment, a heterogeneous azeotropic distillation process is selected. Ratio (referring to the mass ratio of ethanol and raw materials in the ent...
