A contact tray for use in a mass transfer or heat exchange column and having a tray deck with an inlet area and a remotely positioned outlet for respectively receiving liquid on the tray deck and then removing the liquid after it has flowed across the tray deck and interacted with another fluid on and above the tray deck. A plurality of barriers are positioned between the inlet area and the outlet. The barriers each have spaced-apart pickets and openings in the spacing between adjacent ones of the pickets. The pickets impede the flow of the liquid and increase the upstream liquid loading on the tray deck as the liquid flows from the inlet area, through the openings, and then into the outlet. At low liquid flow rates, this increase in the liquid loading may significantly increase the vapor handling capacity of the tray.

A hybrid Contact tray for a mass transfer column is provided. The tray has a deck for passage of liquid along a liquid flow path thereon. The deck also has a plurality of orifices for passage of ascending vapor through the tray deck. The contact tray includes a cross-current vapor-liquid mixing section having a first portion of the plurality of orifices and a co-current vapor-liquid mixing section having at least one co-current mixing device associated with a second portion of the plurality of orifices. The co-current mixing device includes a conduit having: a vapor inlet in fluid communication with one or more of the second portion of orifices; a froth inlet in fluid communication with the liquid flow path; a fluid outlet; and a packing material within a co-current flow path of vapor and liquid within the conduit disposed after the vapor and froth inlets and before the fluid outlet.

The tray deck also has features capable of altering liquid head levels with respect to the plurality of orifices such that the liquid head level within the co-current vapor-liquid mixing section is greater than the liquid head level within the cross-current vapor-liquid mixing section.

Systems and methods are described for dissolving ammonia gas in deionized water. The system includes a deionized water source and a gas mixing device including a first inlet for receiving ammonia gas, a second inlet for receiving a transfer gas, and a mixed gas outlet for outputting a gas mixture comprising the ammonia gas and the transfer gas. The system includes a contactor that receives the deionized water and the gas mixture and generates deionized water having ammonia gas dissolved therein. The system includes a sensor in fluid communication with at least one inlet of the contactor for measuring a flow rate of the deionized water, and a controller in communication with the sensor. The controller sets a flow rate of the ammonia gas based on the flow rate of the deionized water measured by the sensor, and a predetermined conductivity set point.

The invention is a distributor tray having at least one perforated wall defining compartments. The distributor tray has at least one distribution compartment through which gas and the liquid flows through the tray, and at least one retention compartment through which the liquid cannot flow through the tray. The at least one retention compartment is on the periphery of the tray. The invention also relates to a column for heat and/or material exchange between a gas and a liquid equipped with a distributor tray, to a floating barge including the column and to the use of the column.

The contacting device for countercurrent contacting of fluid streams and having a first pair of intersecting grids of spaced-apart and parallel deflector blades and a second pair of intersecting grids of spaced-apart and parallel deflector blades. The deflector blades in each one of the grids are interleaved with the deflector blades in the paired intersecting grid and may have uncut side portions that join them together along a transverse strip where the deflector blades cross each other or adjacent opposed ends of the deflector blades and cut side portions that extend from the uncut side portions to the ends of the deflector blades. At least some of the deflector blades have directional tabs and associated openings to allow portions of the fluid streams to pass through the deflector blades to facilitate mixing of the fluid streams.

Systems and methods are provided for reducing maldistribution of liquids and vapors in packed towers. An exemplary separation system includes a separation tower including at least two packed beds, and a vapor redistribution plate disposed between two sequentially disposed packed beds, wherein the vapor redistribution plate is configured to mix a vapor from a lower packed bed before introducing the vapor into an upper packed bed.
