    Abstract: Provided is a method, liquid distributor and reactor for contacting a gas with a liquid in a rotating packed bed. The method comprises providing a rotating packed bed comprising two sets of rotatable packing rings disposed within a chamber and defining an interior region. The rotating packed bed also comprises at least one liquid distributor with an inlet for accepting a liquid, the inlet in communication with an exit port for infusing the liquid into the interior region. The liquid distributor also comprises at least one gas outlet for accepting gas which has passed through the packed bed and for removing the gas from the interior region. The two sets of rotatable packing rings are caused to rotate. Liquid is infused into the interior region by way of the liquid inlet, and gas is injected through at least one gas inlet into the interior region, with the liquid and gas passing through each of the packing rings in countercurrent flow. Liquid is removed from the interior region through a liquid outlet, and gas is removed through the gas outlet in the liquid distributor.

    Abstract: The invention in one embodiment is a nozzle device for coupling with a fluid distribution conduit for improving the distribution of an upward or downwardly flowing poly-phase mixture including at least one gas phase and at least one liquid phase, above at least one packed bed of granular solid or fluidized bed. The fluid distribution conduit for receiving liquid and gas phases has one or more lateral openings for flow over an upper portion of its height through which a gas phase can enter and has fluid distribution conduit having one or more lateral openings for flow over at least a lower portion of its height through which a liquid phase can enter the fluid distribution conduit. It also has at least one lower cross section for flow through which a mixture of gas and liquid communicate with a packed bed of granular solid or a fluidized bed. The nozzle device includes a venturi nozzle having an outer diameter not greater than an inner diameter of the lower cross section of the fluid distribution conduit, wherein the nozzle device may be fixedly coupled to and co-axially aligned with the lower cross section of the fluid distribution conduit. It is for accelerating and dispersing the liquid and gas phases passing out of the conduit.
