Continuous Distillation

Abstract In the B10 isotope enrichment industry, the purification of anisole mixture makes great sense. A dynamic-accumulative operation policy of continuous distillation (DACD) with repeated filling and dumping of the still is proposed for the separation of trace heavy impurities in the recycled anisole. To simulate and optimize the purification process of anisole, a mathematical model of DACD is derived, and the computer codes are developed in the MATLAB environment. Moreover, the experiment is performed in a pilot-scale distillation column. The results show that the experimental date agrees well with simulation results. DACD could solve the difficulty of flow rate control when the bottom flow rate is very small in continuous distillation. The size of the still in this operation mode is also smaller than that in batch distillation. And the yield of anisole is raised to 99.91%. In a word, DACD is especially suitable for separating trace heavy impurities from the recycled anisole.

Separation Temperature

The research of dimethylbenzene and butylacetate from industrial spent solvent oil by batch distillation was studied, and the batch distillation experiment was by pretreated material. The effects of separation temperature and reflux ratio on separation efficiency were investigated,and compared the new tower with the old one. The experimental results showed that: when the reflux ratio R was 3, Butyl acetate and Xylene product purity were low, the R ≥ 4, the purity of the product of Xylene and Butyl acetate were significantly increased; both yield were lower with the increase of reflux ratio. When R was 4, the top temperature of the distillation column was between 109 and 111.4 °C, before and after device upgrading, Butyl acetate product purity were 90.03% and 72.88% respectively.When the top temperature was above 120 °C, the device after upgrading Xylene product purity was 98% and 94.42% before the upgrading. Both of the purity and the yield improved after device upgrading.
