HYROGEN PEROXIDE PURIFICATION PROCESS AND HYROGEN PEROXIDE

摘要

A hydrogen peroxide purification process, including supplying a starting stream containing hydrogen peroxide at a content above 50 wt %, as well as at least one stabilizer; a single step of purification of the starting stream, the single step having purification by reverse osmosis; collecting a purified stream at the end of said single purification step, in which purification by reverse osmosis includes: passing the starting stream over a first membrane; collecting a permeate and a retentate from the first membrane; passing the permeate from the first membrane over a second membrane; collecting a permeate and a retentate from the second membrane, the purified stream having the permeate from the second membrane.
