Autoclave using steam from the Flash Vessels. This considerably reduces the heating of incoming solution as well as reducing exhaust gas. Flash Vessels decrease the pressure and temperature of slurry that comes from the Autoclave in a controlled manner. Proper sizing of the Flash Vessel is essential to ensure smooth operation of the process and avoid

oxidative system (Portable autoclave Ref 1925X All American), where pressure was increased from 0 to 103 kPa and temperature remains constant at 120°C. The applied pressure modified the partial pressure of oxygen and increased the oxidative reaction rate [17]. With the pressure increase, the reaction time was reduced from 40 to 5 minutes.
