Abstract: 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 evaporation+rectification technology(domestic technology) and one-stage falling film evaporation+one-stage climbing film evaporation+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.

Key words: concentration of hydrogen peroxide, green synthesis, falling film evaporator, rectification, steam ejector
