【摘要】：过氧化氢俗称双氧水,是一种绿色化工产品,其运用前景日趋广泛。本文首先介绍了过氧化氢的性质及应用、过氧化氢生产工艺技术的进展及生产现状,分析了国内外过氧化氢生产技术的差异,结合具体的生产装置介绍了蒽醌法过氧化氢生产技术优化与改造案例,同时探究了蒽醌法过氧化氢工艺中氧化尾气的处理方法。通过对比国内外过氧化氢生产工艺,分析国内外过氧化氢生产技术的差异,为蒽醌法过氧化氢生产工艺技术的优化改造与发展提供参考。以湖北三宁化工股份有限公司新建的15万吨/年双氧水装置为依托,针对装置运行过程中出现的氢化塔堵塔、萃余带水等问题进行分析研究,提出并实施了相应的技术改造方案,取得了显著的效果。氢化塔压差稳定在0.05Mpa左右,萃余带水量减少60%左右,各原辅物料消耗明显降低。在蒽醌法过氧化氢氧化尾气处理工艺的研究中,介绍了氧化尾气的工业处理方法,分析对比了各种工艺处理方法的优缺点。提出了溶剂吸收法来处理氧化尾气回收利用芳烃的新思路。
[Abstract]:Hydrogen peroxide, commonly known as hydrogen peroxide, is a green chemical product. This paper first introduces the properties and applications of hydrogen peroxide, the progress of hydrogen peroxide production technology and the present production situation, and analyzes the difference of hydrogen peroxide production technology at home and abroad. The optimization and modification of hydrogen peroxide production technology by anthraquinone process are introduced in this paper, and the treatment method of oxidation tail gas in hydrogen peroxide process by anthraquinone process is also discussed. The difference of hydrogen peroxide production technology at home and abroad is analyzed by comparing the domestic and foreign hydrogen peroxide production technology, which provides a reference for the optimization and development of anthraquinone hydrogen peroxide production technology. Based on the newly built 150000 t / a hydrogen peroxide plant in Hubei Sanning Chemical Co., Ltd., the problems of hydrogen tower plugging and residual water extraction during the operation of the unit are analyzed and studied. The corresponding technical transformation scheme is put forward and implemented, and remarkable results are obtained. The pressure difference of hydrogenation tower is about 0.05Mpa, the amount of water in the residual zone is reduced about 60%, and the consumption of raw and auxiliary materials is obviously reduced. In the research of oxidation tail gas treatment technology of anthraquinone hydrogen peroxide, the industrial treatment method of oxidation tail gas is introduced, and the advantages and disadvantages of each process are analyzed and compared. A new method of solvent absorption for recovery and utilization of aromatics from oxidation tail gas was proposed.
