    摘要： A structured packing for producing intimate contact between liquid and vapor phases formed of a plurality of juxtaposed sheets through which the liquid phase descends as a film. The sheets have corrugations to define flow channels through the sheets for the vapor phase to ascend through the structured packing and contact the liquid phase. The sheets have a plurality of elongated projections, situated on one or both sides of each of the flow chapels and/or each of the sheets. The projections are configured and oriented to produce turbulent mixing in the vapor phase as it ascends though the packing. This turbulence inhibits the formation of a concentration gradients within the vapor phase in directions normal to the walls of the flow chapels. The elongated projections are spaced apart from one another so that the turbulence and the vapor phase subsides between the elongated projections.

    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 distillation column and method in which a plurality of beds of structured packing are provided within a column shell and are configured to contact liquid and vapor phases of the mixture to be distilled. At least one liquid redistributor is located between the beds of structured packing to redistribute the liquid of the liquid phase and an annular collector is located above the liquid distributor to direct liquid to the liquid distributor. The annular collector acs as a constriction to produce a central flow of the vapor phase which can result in decreased performance of overlying beds of structured packing. In order to overcome this potential problem, a truncated bed of structured packing is provided directly above the annular collector to promote a more uniform distribution of such central vapor flow in a transverse direction of the column shell. The truncated bed of structured packing is fabricated from layers of structured packing each having a height less than that of packing layers of overlying beds of structured packing.

    摘要： A continuous pressure driven adsorption process for separating a multi-component gaseous mixture. In accordance with the method, the multi-component gaseous mixture is passed through a first portion of the adsorbent to adsorb one or more preferentially adsorbed components while a second portion of the adsorbent is regenerated. The multi-component mixture is passed through the first portion of the adsorbent in sections and the second portion of the adsorbent is regenerated in sections. The sections forming the first portion of the adsorbent become successively less saturated and the sections forming the second portion of the adsorbent becomes successively more concentrated in the more preferentially adsorbed component. A product stream is expelled from the less saturated section of the first portion of the adsorbent. The product stream is enriched in the less preferentially adsorbed component(s). Masses of adsorbent are continually being shifted between the first and second portions of the adsorbent so that the mass of adsorbent forming the regenerated section is shifted to the first portion of the adsorbent and used to form the least saturated section. The mass of adsorbent forming the most saturated of the sections is shifted to the second portion of the adsorbent and used to form the non-regenerated section. The masses are shifted at a sufficiently high frequency to maintain the sections forming the first and second portions of the adsorbent in their successively less saturated and successively more concentrated states.
