双氧水生产节能减排的技术措施

Technical measures for saving energy and reducing pollution in the production of hydrogen peroxide

结合作者的生产实践,对近年来双氧水生产方面节约能源、减少污染排放等采取的技术措施进行了分析和总结。主要有增设氢化液/工作液换热器,省略氧化液泵和磷酸泵,提高空气和氢气的利用率,合理处置氧化残液,氧化尾气节能回收,浓缩装置塔顶冷凝液回收利用等,对双氧水生产和装置设计工作有一定的参考价值。

The article analyzes and summarizes the technical measures for saving energy, reducing pollution emissions in the production of hydrogen peroxide in recent years, by referring to the author＇ s production practice. The technical measures include mainly adding hydrogenation liquid / working solution heat exchanger, omitting the oxidation liquid pump and phosphoric acid pump, improving the utilization of air and hydrogen, disposing of reasonably the oxidation residue, recoverng oxidation tail gas by an energy-saving way, recycling condensed liquid on the top of the concentration unit. Such information may provide some reference for hydrogen peroxide production and equipment design.
