Abstract: A process for the separation of a low-boiling gaseous mixture by low-temperature rectification, comprising the steps of:(a) subjecting said gaseous mixture to rectification in a high pressure zone to obtain a crude light fraction and a crude heavy fraction;(b) passing said crude light fraction and said crude heavy fraction to an intermediate pressure rectification zone to obtain an enriched gaseous overhead and an enriched liquid bottoms;(c) passing said liquid bottoms into a low-pressure rectification zone; and(d) withdrawing vapor from said low pressure rectification zone by suction, increasing the pressure of said vapor and passing said vapor into the intermediate pressure rectification zone;Whereby the pressure in the high pressure stage is lower than the pressure in a high pressure stage of a double column employing two pressure stages.

Abstract: Apparatus for removal of deleterious gaseous components from a flue gas, the flue gas is cooled, optionally subjected to preliminary purification, and optionally depleted of SO.sub.2. It is then heated in at least one heat exchanger and is passed over a catalyst suitable for the conversion of nitrogen oxides, whereupon the purified hot flue gas is conducted over at least one further heat exchanger and is discharged in the cooled state. Ammonia is preferably added to the heated flue gas.

Abstract: In a process for the removal of sulfur dioxide and nitrogen oxides, the waste gas is cooled and scrubbed with a physical absorbent selective for sulfur dioxide. The nitrogen oxides are catalytically removed from the waste gas by reaction with ammonia, which is added to the waste gas prior to the scrubbing step. The catalyst packing is disposed in the same housing and is at the hot end of a regenerator for cooling the waste gas and is arranged upstream of the regenerator packing. The cooling is conducted to the dew point so as to dissolve residual ammonia, and air is used to remove the ammonia during regeneration, the resultant heated air being primarily used in the combustion zone.

Abstract: For removing undesired gaseous components, e.g., SO.sub.2, from hot combustion gases (from carbonaceous fuels) by scrubbing with a regenerable absorbent, the scrubbing is conducted with a liquid physical absorbent, e.g., dimethylformamide, at a temperature less than 0.degree. C. The cooling requirements of the scrubbing process are supplied by means of an absorption-type refrigeration unit. The hot combustion gases, prior to scrubbing, are cooled in indirect heat exchange, first with air in an upper temperature range cooling zone, and then with cold combustion gas purified by the scrubbing in a lower temperature range cooling zone. The resultant heated air is used in part as (a) air for combustion, and/or in part as (b) an energy source for the operation of the absorption-type refrigeration unit. A heat pump may be used to supplement the said refrigeration unit. Additionally, the resultant heated air can also be used in part as (c) an admixture to the scrubbed combustion gas mixed, and/or in part as (d) a purging gas for regenerating dessicators arranged in the undesired gaseous components (e.g. SO.sub.2) stream from a regenerator wherein the liquid physical absorbent is regenerated to be recycled to the scrubbing stage.
Abstract translation: 为了通过用可再生吸收剂洗涤从热燃烧气体（来自碳质燃料）中除去不需要的气体组分，例如SO 2，在低于0℃的温度下，用液体物理吸收剂例如二甲基甲酰胺进行洗涤。 洗涤过程的冷却要求通过吸收型制冷单元提供。 在清洗之前，热燃烧气体在间接热交换中冷却，首先用较高温度范围的冷却区域中的空气冷却，然后通过在较低温度范围的冷却区域进行洗涤来净化的冷燃烧气体。 得到的加热空气部分地用作（a）用于燃烧的空气，和/或部分地用作（b）用于吸收型制冷单元的操作的能量源。 可以使用热泵来补充所述制冷单元。 另外，所得到的加热空气也可部分地用作（c）混合的洗涤燃烧气体的混合物，和/或部分地作为（d）用于再生设置在不需要的气体组分（例如SO 2）中的干燥器的吹扫气体， 来自再生器的物流，其中液体物理吸收剂被再生以再循环到洗涤阶段。
