摘要： A wiper band assembly suitable for use in packed distillation columns used in an air separation unit is provided. The wiper band assembly includes specially designed metal or metal alloy wiper tabs that are longer and thinner than conventional wiper tabs. The longer and thinner wiper tabs preferably have a thickness between about 0.05 mm and 0.25 mm and a length greater than about 50.0 mm. The physical dimensions and characteristics of the wiper tabs are selected to avoid permanent deformation during the installation process and provides continuous engagement with the interior surface of the packed column wall when the wiper tabs are exposed to pressure differentials typically seen in such packed distillation columns.

摘要： A structured packing arrangement for reducing vapor bypass in the gaps between the edges of structured packing elements or bricks and the packed distillation column wall is provided. The structured packing arrangement includes a high pressure drop shroud attached to portions of the perimeter of the structured packing elements and in the gap between the edge of the structured packing elements and the interior surface of the distillation column wall. The high pressure drop shroud urges the ascending vapor flowing at or near the edges of the structured packing elements to stay within the structured packing elements instead of escaping through the side of the structured packing toward the distillation column wall.

摘要： The present invention relates generally to a cyclic adsorption process for separating components of a gas stream with at least one adsorber vessel containing at least one adsorber bed undergoing the steps of at least pressurization and depressurization such that the steps are driven by at least one compressor, the compressor undergoing the steps of acceleration and deceleration in association with the steps of pressurization and depressurization. The compressor is operated at or above predetermined speeds which do not generate undesirable frequency pulsations while meeting the requirements of the cyclic adsorption process.
