摘要： A structured packing element comprises a plurality of corrugated sheets and one planar member positioned adjacent to each of the corrugated sheets. The planar member has a top edge and a bottom edge that are at least proximally aligned with the top and bottom edges respectively of the corrugated sheets. The planar member is further characterized by a middle portion having an open area percent that is higher than the open area percents of the top and bottom portions of the planar member. The structured packing element can be used to form structured packings for distillation applications.

摘要： The integrated processes of the dry reforming or partial oxidation upstream of the carbon nanotube-producing reactor are described allowing the carbon monoxide to be produced on an as-needed basis, negating the need to transport carbon monoxide to the production site or store large quantities of carbon monoxide on-site. The apparatuses allowing to carry out such integrated processes are also provided. Carbon dioxide emissions may be eliminated from the carbon nanotube production process. This may be achieved by recycling the carbon dioxide byproduct and mixing it with the feed to the partial oxidation process.

摘要： A method of cryogenically separating a mixture of atmospheric gases within a distillation column system having at least one distillation column. In accordance with the method, liquid and gaseous phases of the mixture of atmospheric gases to be separated are countercurrently passed through structured packing. The column is operated with a pressure greater than 2 bars and with a vapor rate of the vapor phase that is less than a critical vapor rate at which the column floods and which varies with the liquid rate of the liquid phase. Minimum and critical vapor rates at which the column floods are set in accordance with experimentally derived data for maximum column utilization in terms of packing volume or column throughput. Additionally, separation performance in terms of HETP increases with the increase in pressure so that a lower than prior art height of structured packing can be used to obtain a particular separation.

摘要： A structured packing with improved packing elements and method of using the structured packing. Each structured packing element comprises corrugated sheets and planar members alternating with and located between the corrugated sheets The planar members are positioned so that at least the lowermost horizontal edges of the planar members and the corrugated sheets are situated proximal to one another. Perforations provided in the planar members and the corrugated sheets are designed to avoid turbulent flows and bulk fluid flow across the packing element while allowing transverse pressure equalization. Different configurations of corrugated sheets may be used with the planar members to form the structured packing.

摘要： The present invention provides a structured packing comprising a plurality of corrugated sheets and a plurality of flat, planar members alternating with and located between the sheets to inhibit turbulence in vapor ascending through the structured packing. The plurality of planar members are positioned so that at least lowermost transverse edges of the planar members and the corrugated sheets are situated at least proximal to one another as viewed when said structured packing is in use. Each of the planar members and the corrugated sheets has perforations sized to inhibit liquid and vapor flows but to allow pressure equalization. The planar members can be strip-like and positions at or near the top and bottom transverse edges of the corrugated sheets or can have the same length and width of the corrugated sheets. The size and number of perforations can be optimized for air separation applications.

摘要： A liquid-vapor contact column comprising a column shell and one or more beds of structured packing located within the column shell. Each bed of structured packing includes a plurality of vertical stacks which are formed of at least two upper and lower levels of structured packing. The structured packing is partitioned to form the vertical stacks. When the structured packing is formed from corrugated sheet material, the vertical stacks can also be spaced from one another with the corrugated sheets making up the structured packing rotated 90.degree. with respect to boarding vertical stacks of structured packing. The partitions or the rotated arrangement of the packing inhibit liquid migration in a transverse, horizontal direction of the column. This promotes constant liquid and vapor flow characteristics through each of the vertical stacks of structured packing to resist widespread liquid channeling throughout the column.
