Abstract: A structured packing element for a column for at least one of mass transfer and heat exchange between a heavy fluid phase and a light fluid phase. The structured packing element comprises at least two layers of a grid comprising openings that are surrounded and separated from each other by separating elements. At least two of the layers are arranged in a longitudinal direction parallel and in touching contact with each other such that an open space extending from one end to an opposite end of the layers is provided between the layers such that at least one of the heavy fluid phase and the light fluid phase may flow therethrough. An average width of at least 50% of the separating elements between adjacent openings is at least 15 times a layer material thickness and is between 70% and 125% of an average hydraulic diameter of the adjacent openings.

Abstract: 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.

Abstract: Provided herein are methods and systems for converting natural gas, and specifically methane, into higher-value oxycarbon products, such as methanol, methyl formate, and formic acid. The natural gas is introduced into an aqueous solution with hydroxyl radicals and reacted in ambient conditions to form the desired products in the presence of a metal catalyst. The methods described herein overcome the “over-activation” dilemma of prior art methods that lead to the formation of undesirable carbon oxide compounds. Methods and apparatus for forming hydrogen peroxide via electrolysis and for forming hydroxyl radicals from the hydrogen peroxide via reaction with ferrous ions are also provided.

Abstract: A bundle assembly for vertical, gravity flow driven polymerization reactors for combinations of high viscosity, high throughput, and thin polymer films is provided. The bundle assembly includes static internal components that provide large areas of free liquid surfaces in contact with the atmosphere of the reactor while still attaining sufficient liquid holdup times for polymerization to take place. The bundle assembly includes one or more stationary film generators. The bundle assembly further includes one or more stationary arrays of film support structures. Each of the film support structures has a first side and a second side. Both sides of the film support structure are coated with flowing polymer. The vertical arrangement of components in the bundle assembly cause the polymeric melt to cascade down the vertical length of a reaction vessel interior that incorporates the bundle assembly. The present invention also provides a polymerization reactor that incorporates the assembly of the invention and a method of increasing the degree of polymerization of a polymer melt by using the assembly of the invention.

Abstract: A device for maximum vapor or gas throughput is provided for material and/or energy exchange, in which large vertical flow spaces are present. Vapors or gases flow without impact losses and thus with extremely low pressure loss per meter in counter flow to liquid on zigzag wires or threads arranged vertically next to one another, produced with conventional web or braiding machines, along wide-meshed fabric or grid webs and are brought for exchange with the liquid. Simultaneously, by optimizing the wire or thread diameter and its count and the arrangement of fabric or grid webs, considering the large vertical flow spaces and a uniform wetting of the large number of zigzag wires or threads arranged vertically next to one another against the wave peaks, a minimal specific volume of the device is achieved by wide-meshed fabrics or grids for the vapor or gas flow through a step-wise division of the trickling liquid.

Abstract: The invention relates to a wash column for material and/or energy exchange between media, especially between a liquid trickling down and a gas or a lighter liquid rising in a counter-current. The invention especially relates to a novel structural packing that comprises liquid guide elements (19) in the form of wires or threads that form substantially rhomboid masses with vertical axes in imaginary surfaces (21) and that surround, for example in a polygonal grid, substantially free, vertical flow channels (22) for the counter-flowing gas. The nodes (18) of the liquid guide elements (19) are located at the respective points of intersection of a horizontal cross-section grid. The distance between the guide elements or the size of the meshes is chosen such that the liquid does not form film curtains and flows off only in defined flows, linearly along the guide elements (19). At the ends of the packing, the guide elements (19) for the introduction of liquid and for the draining-off of liquid are bundled step-wise to common strands for introducing or draining off liquid.
