The invention provides a cellular packing including a vapor/liquid separation device that can be stacked vertically with minimum wasted space. The packing uses static vanes in each cell to direct the liquid component of a vapor/liquid mixture to exit slots in a first cell and a recirculation path for the liquid to be contacted with vapor again in a second cell located below the first.

Fluid separation packing

The invention provides highly deformation resistant Lessing rings made in two parts. The first part comprises a metal strip bent into a ring shape with the contacting ends provided with projections and indentations which fit together to form a complete ring. The ends are held together using an anchor strut which has projecting tabs at both ends. The tabs fit into cooperating slots located in the projections at the ends of the bent strip and at the midpoint of the bent metal strip. The tabs are bent over to locate all parts rigidly in place.

Packing element

Tower packing element

Channel beams of a particularly advantageous design are provided. These can be assembled to form a non-welded support plate in a confined environment having any desired configuration and later disassembled and reused elsewhere. The support plates are designed to support tower packing materials whether of the structured or dumped kind.

Non-welded support plate member

Corrugated tower packings which are easier to fabricate from individual corrugated elements having parallel rows of ridges and valleys wherein the elements are provided with extension tabs along the ridges of at least a first surface of such elements to provide a location at which the tabs can be spot welded to a contacting element to provide a rigid structure.

Securing packing elements

A non-welded plate for supporting packing materials or limiting the upward movement of such packing materials in a packed column of a gas and liquid contacting apparatus is comprised of a plurality of first and second support beams. The first support beams have means for fastening to internal support members of the apparatus affixed thereon. The first and second support beams are essentially perpendicular to each other and are attached together by retaining means, such as a pin. Voids between the support beams may be covered with screen to provide further support or limitation.

Non-welded support plate or bed limiter for packed towers and method of

A low flow liquid distributor and redistributor for a liquid/gas contact tower comprises: one or more receptacles each extending over a cross sectional area of the tower chamber and adapted to receive a source of liquid supplied either directly thereto or indirectly from the source via liquid feed splitter means that divides and dispenses the liquid received to each receptacle. Each receptacle has at least one side wall including one or more metering weirs dividing the liquid flow into one or more streams directed against a liquid distribution drip plate situated relatively close to the sidewall of the receptacles. Each liquid distribution drip plate has an upper portion extending downwardly to a short horizontal wall both of which causes liquid to spread horizontally and fill the narrow space between it and the sidewall of the receptacle and flow downwardly over the horizontal wall, through apertures in an adjoining side portion and a lower serrated portion extending downwardly therefrom composed of a number of angularly disposed drip portions and edges adapted to direct and uniformly divide low rates of liquid flow over the cross sectional area of the liquid contact tower chamber and a bed of tower packing elements therein.

Liquid distributor

Precision molded plastic cellular packing elements (10 and 40) of polygonal and curvilinear spriral shape are provided for mass transfer and effluent treatment apparatus. Each spiral element (10 and 40) has more than one convolution (16 and 46), a maximum transverse width (W) significantly greater than its axial height (H) whereby it has a greater tendency to orient itself horizontally and its relatively shorter wall surfaces substantially vertical, angularly spaced ribs (24-26) (52-54) which extend from the axis (x) and interconnect the convolutions; and wherein adjacent wall portions of the ribs and of the spiral convolutions around open end cells of the element are either in alignment or inclined in one direction, or oppositely inclined relative to one another whereby the element may be provided with either or a combination of straight, tapered or oppositely tapered cells.

Randomly dumpable self orienting spiral packing elements

A fluid injection packing support with improved directional fluid flow characteristics, increased strength, rigidity and load carrying capacity includes a plurality of adjoining elongated hollow sections extending across a tower chamber and supported at opposite ends by a ledge fixed to the wall around the chamber. Each section has a spaced pair of inclined sidewalls diverging downwardly from an upper arched top wall portion to adjacent horizontal wall portions extending to adjoining short vertical wall portions. The inclined and horizontal wall portions have apertures with smoothly curved entrances and raised flange portions extending around and projecting to more sharply defined exit ends of the apertures which not only strengthens the wall and section but provides low resistance to the entrance and flow of the counter flowing fluids in one direction and greater resistance to the entrance and flow of the counter flowing fluids from the opposite exit ends of the apertures. Thus, the greatest part of the upwardly and downwardly moving fluids pass through separate apertures with little resistance which reduces the pressure drop across the packing support.

Tower packing support

Support block for chemical tower packing

A low flow liquid distributor for liquid/gas contact apparatus having a liquid feed splitter dividing the flow into a plurality of streams, an array of troughs extending across the cross sectional area of the contact apparatus, below the splitter, collects the plurality of streams and further divides the flow into a greater number of streams. A shallow pan situated under each of the troughs collects the streams and has upturned sides with drain openings extending upwardly from at least the junction with a downwardly sloping bottom of the pan of greater number than the streams deposited in the pan whereby low rates of liquid flow are obtainable and uniformly distributed onto a bed of tower packing for contact with a gas flowing therethrough.
