Abstract: A small deaeration tank and a process of operating this tank which may be either at atmospheric pressure or under low pressure or vacuum and a system of operating this tank which allows pulp which has been treated with oxygen to be deaerated before being washed. A closed tank would allow steam or oxygen to be recovered. Preferably it would be the same diameter as an oxygen reactor so that it could be placed on top of the reactor and be supported by the reactor. It would have no moving parts, so there would be no need for motors to be mounted on or near the tank. The deaerator is a small open tank (50) having an inlet pipe (27) and a tangential swirl inducing inlet pipe (57). The locations and sizes of these pipes provide optimum deaeration. The swirl inducing fluid is the filtrate from the washer (36) after the oxygen bleach (23).
