摘要:

通过实验模拟了馏分脱酚过程,考察了反应时间、反应温度、加碱密度、加碱量对脱酚效率的影响,考察了静置时间对酚盐中性油的影响以及不同的轻油对酚盐洗涤效果的影响,得出了馏分脱酚的最佳工艺条件。以实验数据为基础,结合现场实际情况,优化和调整了馏分脱酚工艺操作参数。改进后酚油、萘油、洗油的脱酚效率分别提高了3.7%、2.6%、4.9%,酚盐中性油、游离碱含量分别下降了48%、37%。

Abstract:

By simulating the phenol removal process in the laboratory,the influence of reaction time,reaction temperature,density and flow of NaOH on the dephenolization efficiency,the influence of settling time on neutral oil content in phenol salt,and the influence of different light oil on the washing result of phenol salt are studied.Based on the result the optimum process conditions are finalized for fraction dephenolization.On the basis of experimental data and the actual condition at site,the process operation data are optimized and adjusted.After improvement,the dephenolization efficiency of phenol oil,naphthalene oil and washing oil is increased by 3.7%,2.6% and 4.9% respectively.The neutral oil and free alkali are decreased by 48% and 37% respectively.
