Sparging

Hello,

I'm the vice president of the Iowa State Space Society. We purchased  
a Systeme Solaire SS67B-3 peroxide/gasoline kit engine as an  
introduction to liquid-fueled engines.

I'm interested in building a batch sparging machine for the  
production of minimum 90% peroxide from 50%, both to improve the  
thrust of our current engine and enable the production of new, higher  
performance engines. We don't plan to reach LEO like ERPS, but I  
think 100km is within reach.

Is there a reference you have found particularly useful, or an avenue  
of research that should be pursued? Caveats or dead ends to be aware of?

Thanks,
Ben Brockert
