A hollow, saddle-shaped packing structure includes a pair of porous outer and inner semi-cylindrical side walls that are spaced from one another to define an interior space and a particulate catalyst component retained in the interior space between the side walls. The packing structure may be formed by a pair of saddle-shaped shell elements each of which presents one of the side walls and a pair of radially opposed laterally extending flanges The flanges are connected together by tabs welding, or the like, and the interior space between axially spaced marginal edges of the outer and inner shell elements is closed off to retain the particulate catalyst component between the side walls.

A plurality of corrugated plates are arranged in parallel relationship with corrugations in adjacent plates extending in a criss-crossing pattern to form a packing element for a heat exchange or mass transfer column. The plates are spaced closer together by providing reliefs in adjacent plates at the points of intersection between the criss-crossing corrugations. The reliefs allow the corrugations on the adjacent plates to extend into each other to reduce the spacing between the plates. The reliefs may be in the form of apertures or recesses.

A motionless mixer for use in mixing flow streams in a conduit and a low-cost method of manufacturing the motionless mixer, which method comprises: cutting, such as by stamping, an elongated strip from a flat sheet, which strip comprises a plurality of connected, semielliptical blade elements; bending the strip at the connecting point between the blade elements, to form a plurality of blades at an angle of about 30.degree.-45.degree. to each other in the strip; providing first and second strips and aligning the first and second strips in a generally parallel arrangement; twisting the said first and second strips into a cooperative relationship, wherein each pair of blade elements is disposed at an angle of about 90.degree. with respect to each other pair of blade elements; securing the blade elements together such as by welding at the crossover point of the pair of blade elements, to provide a motionless mixer; and inserting the motionless mixer in a conduit.

An improved vapor-liquid contact grid apparatus which maximizes the generation of small drops and which is inexpensive to manufacture and easy to construct is disclosed. The grid apparatus consists of multiple layered grids, each grid being formed of upright grid members and connectors. The grid members carry vanes, formed from the member itself by a process of slitting and bending, which vanes extend out into the region between the upright grid members, thus restricting vapor passage, providing drip points and increasing the effective surface area for gas-liquid exchange. The grid members and connectors are arranged in an 'egg carton'-like fashion to provide a simple, yet sturdy, grid.
