P2O5 IBC Tote Transfer System

Matrix designed and supplied a custom batching system to a reactor of the extremely difficult powder, Phosphorus Pentoxide (P2O5).  The powder is highly hygroscopic and forms a corrosive hard/sticky crust when exposed to moisture or humidity.  Our batching system was designed to receive the powder from IBC totes and precisely meter it into a wet reactor.  When P2O5 is in contact with water, it reacts exothermically with extreme heat release and hot phosphoric acid steam.

Using our sealed tote transfer design, we were able to control the infiltration of moisture and lumping inside the batch hopper.  The controlled venting of the sealed tote dump and the overall robustness of the system improved the performance tremendously.  The previous system required cleaning on an almost weekly basis to remove hardened P2O5 and boulder/lumps.  The cleaning was also cumbersome and potentially hazardous job due to the nature of P2O5 and water.   Our Matrix design allowed 6-8 months between cleanings.
