Abstract: A method and apparatus are provided for the controlled application of ultrasonic energy for conditioning of mixtures of gas and liquids by evolving and/or agglomerating gas bubbles existing with or in a liquid or for coalescing droplets of liquid dispersed in another liquid. The invention in preferred embodiments thereof comprises a coalescing apparatus for increasing the droplet size of a mixture formed as a liquid dispersed in another liquid, and a de-gassing apparatus arranged to evolve and/or agglomerate gaseous bubbles in a gas/liquid mixture. In the apparatuses, ultrasonic transducers are used to impart vibrational energy to the mixtures.

Abstract: A conveyor apparatus for conveying solid material in a process vessel includes, a first baffle set comprising a plurality of inclined baffles located above the eductors and arranged to restrict upward flow of solids in the direction of movement of the solids. A second baffle set may be used to prevent particles rebounding from an end wall and back into upper levels of the vessel.

Abstract: Fluid processing apparatus comprising a vessel containing a hydrocyclone and defining an inlet chamber, the vessel having a vessel inlet arranged to feed fluid into the inlet chamber, being arranged to receive fluid from the vessel inlet and to pass the fluid to an inlet of the hydrocyclone. The inlet chamber includes coalescing means arranged to coalesce relatively small droplets contained in the fluid received at the vessel inlet into larger droplets before passing the fluid to the hydrocyclone inlet. The coalescing means having a substantially predetermined external shape which defines at least one elongate liner hole for receiving a respective hydrocyclone liner.

Abstract: An apparatus and method for conveying solids from a process vessel in which the vessel has a plurality of eductors sequentially oriented end-to-end from a vessel inlet to the vessel outlet. Conveying fluid enters the inlet drawing bulk particulates via the eductor series through the outlet.
