The invention relates to a method for recovering energy and water from pressure oxidation flash steam where first flash steam directly obtained from a flash vessel is contacted with a first recirculating condensate having a first low condensate temperature to condense at least part of the water vapor in the first dirty flash steam and simultaneously to heat the first recirculating condensate to obtain a first recirculating condensate having a first high condensate temperature and a first vent steam. The invention further relates to a pressure oxidation arrangement adapted for use in the method.

A liquid treatment apparatus (10) for processing a liquid includes an inlet nozzle (12) having an orifice (16) for directing a flow of liquid through the orifice (16) to define a fluid jet, and a concial diffuser (18) including a tip (20), a base portion (22), and a curved surface (26) therebetween. The conical diffuser (18) is generally aligned with the orifice (16) such that the fluid jet impacts upon the tip (20) of the conical diffuser (18). Moreover, the curvature of the curved surface (26) is selected to maintain a substantially constant Froude number of the liquid along the conical diffuser (18).

A device and a method for influencing the flow of a flowable medium through a flow-through reactor are described. The flow-through reactor has at least one inlet opening and at least one outlet opening, through each of which a flowable medium can flow in or out. By means of at least one energy source for changing at least one property of the flowable medium flowing through the flow-through reactor, energy can be introduced whose intensity is non-uniformly distributed in the volume of the flow-through reactor. According to the invention, the flow of the flowable medium flowing through the flow-through reactor is influenced by at least one mechanical component positioned in the flow-through reactor in such a way that a majority of the flowable medium flowing through the flow-through reactor flows through the zones of high energy intensity generated by means of the energy source.
