摘要
介绍了双氧水浓缩工艺发展的背景和意义;分析了两段升膜蒸发加精馏技术(国内技术)和一段降膜蒸发加一段升膜蒸发再加精馏技术(引进技术)这两种双氧水浓缩工艺技术中需要改进的问题;阐明了新型国产双氧水浓缩工艺技术的特点;给出了3种双氧水浓缩工艺的技术经济指标对比,并根据投资实例,指出新建或旧装置改造的投资和经济效益情况。
Background and significance of the development of hydrogen peroxide concentration technology were introduced. Problems need to be solved in two existing hydrogen peroxide concentration technologies, i.e.two-stage climbing film evapora- tion＋rectification technology （domestic technology） and one-stage falling film evaporation＋one-stage climbing film evapora- tion＋rectification technology （imported technology）, were analyzed.Characteristics of a new-type homemade hydrogen peroxide concentration technology were elaborated and a comparison was made on the economic and technical norms among the three technologies.Furthermore, the investment and the economic benefit for setting up a new hydrogen peroxide plant or revamping the old ones were pointed out based on the real investment cases.
