摘要： A structured packing is formed of packing elements. Each structured packing element comprises corrugated sheets and planar members alternating with and located between the corrugated sheets. Each pair of corrugated sheets 706 and 708 have corrugations 710 which are relatively steeply inclined at their ends. Thus, the angle of inclination of each corrugation 710 to the horizontal in middle portion 14 is less than in upper portion 712 and lower portion 716. Planar member 702 and 704 are positioned between sheets 706 and 708. The bottom horizontal edge 736 of member 704 is proximal the bottom horizontal edges of the sheets 706 and 708. The top horizontal edge 720 of member 702 is proximal the top horizontal edges of sheets 706 and 708.

摘要： Synthesis gas comprising hydrogen, water, carbon monoxide, carbon dioxide, and hydrocarbons is produced by contacting a gasified hydrocarbon feedstock and an oxidant in a partial oxidation reactor under at least 95% carbon monoxide selective, low hydrocarbon conversion conditions wherein the temperature, pressure, and flow rate conditions in the reactor yield synthesis gas having less than about 2% carbon dioxide. After being cooled, The synthesis gas is separated into high purity hydrogen, high purity carbon monoxide and a hydrogen-carbon monoxide gas mixture by pressure swing adsorption followed by cryogenic distillation or by two or more pressure swing adsorption steps.

摘要： A method for producing carbon dioxide and nitrogen from combustion exhaust gas containing less than about 10% oxygen by weight comprises the steps of (a) treating the exhaust gas to remove particulate matter, (b) compressing the exhaust gas to a pressure in the range from about 25 psia to about 200 psia, (c) purifying the exhaust gas to remove trace contaminants, (d) separating the exhaust gas to produce a carbon dioxide rich fraction and a nitrogen rich fraction, (e) liquefying the carbon dioxide rich fraction and distilling off volatile contaminants to produce pure carbon dioxide, (f) purifying the nitrogen rich fraction to remove contaminants, and (g) cryogenically fractionally distilling the nitrogen rich fraction to produce pure nitrogen and preferably arc argon-enriched fraction which is then separated to produce argon. The combustion exhaust gas may be obtained from an ammonia plant reformer furnace and the nitrogen produced may be employed to synthesise ammonia. The carbon dioxide may be reacted with the ammonia to form urea.

摘要： A distillation method and column in which a gaseous mixture (18) is introduced into a bottom region of a packed column (1) having a plurality of packed beds (12,14,N,N+1) using structured packing. The gaseous mixture comprises higher and lower volatility components The packed column (1) is operated so that the higher and lower volatility components have a relative volatility within the column in a range of between 1.05 and 1.8. In order to alleviate the effect of liquid maldistribution in the lowermost bed (12) of such a column, the lowermost bed (12) is sized to be between about 50% and about 80% of the height of the next overlying bed (14), with 80% being preferred, and the total height of the packing within the column being at least about six meters.

摘要： A liquid distributor 1 for a distillation column for distributing an ascending liquid phase to be contacted with an ascending vapour phase within the distillation column. A tray 10 is provided for collecting the descending liquid phase and has rows 12, 14, 16, 18, 20, 22, 24 of apertures for downward passage of the descending liquid phase. Rows of vapour risers 26A, 26B; 28A, 28B; 30A, 30B; 32A, 32B; 34A, 34B; 36A, 36B are located between the rows 12, 14, 16, 18, 20, 22, 24 of apertures for passage of the ascending vapour phase through the tray. Elongate liquid collectors 38, 40, 42, 44, 46, 48 are located above the rows of vapour risers 26A, 26B; 28A, 28B; 30A, 30B; 32A, 32B; 34A, 34B; and between the rows 12, 14, 16, 18, 20, 22, 24 of apertures for collecting all or part of the descending liquid phase before the descending liquid phase reaches the tray 10. The elongate liquid collectors 38, 40, 42, 44, 46, 48 have slots or openings 54 for collecting and then redistributing the descending liquid phase caught therein over a central region of the tray 10. Such redistribution prevents replication of maldistribution throughout the column. The vapour risers 26A, 26B; 28A, 28B; 30A, 30B; 32A, 32B; 34A, 34B; 36A, 36B; can be connected to a distributor trough 50 and be given a rectangular cross-section to provide a sufficient structural rigidity to the tray 10 to enable it to be fabricated from sheet metal with a riveted construction.

摘要： A method of recovering a light element comprising hydrogen or helium from a high pressure feed stream. The feed stream comprises the light element in a concentration of less than 30% by volume and also, hydrocarbons and trace heavy contaminants. Methane and nitrogen may be in the high pressure feed stream if derived from a natural gas source. The trace heavy contaminants are removed from the high pressure feed stream through absorption in one or more beds of activated carbon and the feed stream, still at high pressure, is passed through a membrane unit having a membrane design to allow permeation of the light element while rejection of the hydrocarbons, possibly methane, and nitrogen. The membrane unit produces a process stream enriched to somewhere above 40% in the light elements and a mass flow rate that is only a fraction of the mass flow rate of the feed stream. The process stream is then compressed and subjected to a pressure swing adsorption process utilizing one or more adsorbents to least absorb the hydrocarbons to produce a product stream highly enriched in the light element or 98% enriched and above. Since the mass flow rate of the process stream is very low, very little energy need be expended in compressing the process stream as compared with prior art processes using cryogenic rectification. Additionally, since the waste stream is rejected at pressure, if the pressure is high enough, it can simply be returned to a source of the feed stream without recompression or if not being supplied at a requisite high pressure, it can be recompressed with a blower and then returned to the supply.
摘要翻译：从高压进料流中回收包含氢或氦的轻元素的方法。进料流包含浓度小于30体积％的轻质元素，以及烃和痕量重的污染物。如果源自天然气源，甲烷和氮气可能在高压进料流中。通过在一个或多个活性炭床中的吸收从高压进料流中除去痕量重的污染物，并且仍然在高压下的进料流通过具有膜设计的膜单元以允许轻元素的渗透同时排除烃，可能是甲烷和氮气。膜单元产生在轻元素中富集到40％以上的工艺流，并且质量流量仅为进料流质量流量的一部分。然后将工艺流压缩并进行利用一种或多种吸附剂的变压吸附方法以最少吸收烃以产生高度富集在轻元素中的产物流或富含98％以上的产物流。由于工艺流的质量流速非常低，与使用低温精馏的现有技术方法相比，在压缩流程中需要很少的能量消耗。此外，由于废物流在压力下被排出，如果压力足够高，则可以简单地将其返回到进料流源而不进行再压缩，或者如果在必要的高压下不被供给，则可以用鼓风机然后回到供应。

摘要： A process and apparatus for producing a high purity nitrogen vapour product from the rectification of air within high and low pressure columns 24 and 26 respectively, operatively associated with one another by a condenser-reboiler 28. The high pressure column incorporates a sufficient number of theoretical stages to produce a high purity nitrogen vapour which downstream of being condensed in the condenser-reboiler 28, serves partially to condense in a heat exchanger 42 a lower purity nitrogen fraction produced at the top the low pressure column 26. In such service, the condensed, high purity nitrogen vapour is at least partially vaporized and utilized as a product stream. Since there is intermixing with the high purity nitrogen produced within the high pressure column 24 and the lower purity nitrogen vapour produced in the low pressure column 26, the low pressure column 26 can incorporate fewer theoretical stages and therefore can be built at less expense than similar air separation plants of the prior art.
