One exemplary embodiment can be a device for a gas-liquid contacting apparatus. The gas-liquid contacting apparatus can include a member. The member can include:

Device for gas-liquid contacting

Improved contacting stages for carrying out vapor-liquid contacting are described. Particular aspects are directed to co-current vapor-liquid contacting devices with non-parallel contacting stages that provide an efficient usage of column space for fluid flow and contacting, in order to achieve high capacity, high efficiency, and low pressure drop. The fabrication of such contacting stages is improved using one or more structural enhancements, preferably a combination of enhancements, to achieve easy installation and significantly improved rigidity between the various parts and thereby avoid movement/separation of these parts. This reduces the possibility of fluid leakage across, and consequently vapor and/or liquid bypassing of, the contacting stage.

Contacting stages for co-current contacting apparatuses

The invention provides a vane-type mist eliminator device having formed or corrugated sheets, flat sheets, and integral louvers. The corrugated sheets and flat sheets are layered such that the arrangement of sheets and integral louvers creates at least one tortuous fluid flow channel from an inlet to a vapor outlet of the device An outer casing or frame is sufficient to hold the sheets together.

Vane-type demister

The invention is a high capacity and high efficiency co-current vapor-liquid contacting apparatus for use in distillation columns and other vapor-liquid contacting processes. The apparatus is characterized by an arrangement of modules in horizontal stages rather than tray-like construction. The modules define a co-current contacting volume and in an exemplary configuration the modules include a liquid distributor, a demister, a receiving pan and a duct. The modules of one stage are rotated to be non-parallel with respect to the modules of an inferior stage, a superior stage, or both. Variations relate to the design of the individual elements such as the demister, liquid distributor, ducts, and contacting volumes, and the overall arrangement of the apparatus.

Co-current vapor-liquid contacting apparatus

The performance of multiple downcomer fractional distillation trays is improved by intercepting the liquid egressing from the bottom of the downcomers in a manner which directs a portion of the liquid along the major axis of decking of the next lower tray. This is accomplished by the use of improved antipenetration pans suspended below the downcomers of the upper tray. The antipenetration pans have extensions running parallel to the decking areas of the next lower tray. A portion of the liquid falling from the upper downcomer flows to the end of the extensions, where it falls onto the lower decking at more distant points than with prior art antipenetration pans.

Multiple downcomer fractional distillation tray and process

A low cost antipenetration pan for use on fractionation trays is attached to the bottom of downcomers via releasable clips which slide through slots in the bottom of the downcomer. The clips are at the end of the legs of the pan, and the legs may slide upward through the slots to allow the legs to nest within the downcomer during shipment.
