Concentrated oxygen-ozone mixtures stability at high pressure

摘要

Since many years, ozone is used in water treatment at relatively low concentration and low pressure. There is now a great interest to use ozone at high concentration and high pressure. The main industrial application is the bleaching of pulp, in which ozone is replacing chlorinated bleaching agents. For bleaching of medium consistency pulp, ozone is used at pressures up to belaching agents. For bleaching of medium cosistency pulp, ozone is used at pressures up to 10 or 15 bar g and concentrations of 10 wt-
