Together with the German Degussa AG, successful pilot plant test for the
purification of hydrogen peroxide have been performed. Since hydrogen peroxide
has a high energy content and decomposes to water and oxygen it is used as an
oxidizer/propellant for aircraft rockets in space technology. Process safety
has been the mayor incentive for Degussa when they decided to investigate the
GEA Messo PT technology for their application in more detail. At an impurity
level in the crystallizer of 15 wt% purification ratios between 300 and 3000
have been achieved. During the tests hydrogen peroxide was produced at
concentrations between 99.9 wt% and 100 wt% and at a surprisingly low amount of
other impurities usually under or close to the detection limit of the
individual components. The high efficiency of the wash column separation
becomes apparent when comparing this with “normal” centrifuge separation. Wash
column separation was typically a factor 10 better than conventional
centrifuges.
