Decrystallization/Hydrolysis Vessel Home | Technology | Site Map

All physical parameters of the batch hydrolysis mixture are monitored. The unit is fully instrumented with several thermoprobes (to measure all fluid temperatures), an IR temperature measurement device (to provide an independent measurement of the surface temperature of the bulk mass), motor amp transducers (to determine bulk turnover rates and to measure kinetic energy inputs due to mixing), and vacuum transducers. The reactor skid features an integral control panel (seen to the right of the vessel) for mixer control and for operation of the condenser unit, mounted above the reactor.

A vacuum pump is used in conjunction with the cooling jacket to cool the mass during the exothermic decrystallization phase. In this mode, the condenser insures that any steam which evolves from the reaction is returned to the vessel for continued mixing.

Upon completion of the reaction, the discharge shoot is opened manually to allow flow into the high viscosity, positive displacement pump and out to either of the plate and frame filter units.
