【摘要】 采用弛豫法对文题所述系统进行了模拟计算。结果表明,尽管三聚甲醛(TO)在该系统中相对挥发度较高,但受到甲醛、水浓度变化的制约,TO增浓缓慢,当理论塔板多于8块后,其增浓效果更不明显。
【Abstract】 A distillation column is used for preparing trloxane from the concentratedformaldehyde aqueous solution with a reboiler performing as a reactor. Using a relaxationmethod this article simulates the process for separating the mixture ofwater-formaldehyde-trioxane.Calculation results show that the:oncentration of trioxanevaries rather slowly along the column even having high relative volatihty in the mixure.
