Abstract
An apparatus is provided for oxidizing an aqueous suspension of organic matter at elevated pressure. The apparatus has a reactor and an inlet for the aqueous suspension which is introduced to an upstream end of the reactor. A device for circulating the aqueous suspension through the reactor. An inlet for an oxygen containing gas introduced to the aqueous suspension. An outlet for removing treated aqueous suspension from a downstream end of the reactor and a static mixer vane arrangement for splitting, rearranging and combining the aqueous suspension as the circulating device circulates the aqueous suspension through the reactor. The improvement comprises withdrawing the treated aqueous suspension from the downstream end of the reactor and combining a major portion thereof with fresh incoming aqueous suspension. The circulating device returns the combined aqueous suspension to the reactor via the inlet for the aqueous suspension. A minor portion of the withdrawn aqueous suspension is disposed of while at the uppermost region of the reactor, spent gases are removed therefrom as separated from the aqueous mixture.
