System and for improving the movement and discharge of material from vessels

A filtrate addition system for producing a uniform filtrate distribution in the blow dilution zone of a continuous digester comprising:

• (a) a blow dilution header/nozzle assembly located in the blow dilution zone comprising
• (i) a side dilution header/nozzle assembly having a plurality of nozzles for introducing and distributing filtrate into the blow dilution zone and at least one measurement and control device corresponding to the nozzles for monitoring and controlling filtrate flow therethrough, and
• (ii) a bottom dilution header/nozzle assembly having a plurality of nozzles for introducing and distributing filtrate into the blow dilution zone and at least one measurement and control device corresponding to the nozzles for monitoring and controlling filtrate flow therethrough, wherein the at least one measurement and control device of the side header/nozzle assembly is independent from the at least one measurement and control device of the bottom header/nozzle assembly.

A filtrate addition system for producing a uniform filtrate distribution in the blow dilution zone of a continuous digester comprising:

• (a) a blow dilution header/nozzle assembly located in the blow dilution zone comprising
• (i) a side dilution header/nozzle assembly having a plurality of nozzles for introducing and distributing filtrate into the blow dilution zone and a measurement and control device corresponding to each nozzle of the plurality of nozzles for monitoring and controlling filtrate flow therethrough, and
• (ii) a bottom dilution header/nozzle assembly having a plurality of nozzles for introducing and distributing filtrate into the blow dilution zone and an individual measurement and control device corresponding to each nozzle of the plurality of nozzles for monitoring and controlling filtrate flow therethrough.

A method for producing a uniform filtrate distribution in the blow dilution zone of a continuous digester comprising:

• (a) introducing and distributing filtrate through a plurality of nozzles of a blow dilution header/nozzle assembly in the blow dilution zone of the continuous digester;
• and
• (b) measuring and controlling the filtrate flow through each nozzle of the plurality of nozzles.
