馏分脱酚操作参数的研究和改进

Abstract

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.
