Abstract
Chips are sluiced from a low-pressure section to a high-pressure section with a sluice feeder. The fluid that is used to expel the chips from the sluice feeder principally includes pressurized fluid withdrawn from the treatment vessel. This pressurized fluid is normally withdrawn from the treatment vessel for recovery (REC). By using this pressurized fluid instead for expelling the chips from the sluice feeder and subsequently sending the previously pressurized fluid to the recovery system (REC), the requirement for high pressure pumps that consume large quantities of electrical energy can be considerably reduced.
