摘要： The present invention relates to a process for purifying a wastewater stream WW1 contaminated with nitrobenzene, comprising (I) stripping of the wastewater stream WW1 with a stripping gas SG1 in a continuously operated stripping column to obtain a wastewater stream WW2 which contains nitrobenzene in a concentration reduced relative to WW1 (cNB,WW2), (II) further purification of the wastewater stream WW2 in a wastewater treatment plant, wherein a target value (cNB,WW2,TARGET) is specified for the concentration of nitrobenzene in the wastewater stream WW2, which is greater than zero but takes into account the requirements of the wastewater treatment plant for the maximum content of nitrobenzene in the wastewater streams supplied thereto, wherein, for at least one combination of specified boundary conditions of (a) nitrobenzene concentration in WW1, (b) the temperature of WW1, and (c) the temperature of SG1, a set of linear mathematical relationships of the type mSG1=x·mWW1 is stored in a database, which linear mathematical relationships define a range of concentrations of nitrobenzene in WW2, wherein the set comprises, in addition to a mathematical relationship (0) which corresponds to the target value cNB,WW2,TARGET, at least a first mathematical relationship (1) for a first value of cNB,WW2, which corresponds to 98% of the target value cNB,WW2,TARGET, and a second linear mathematical relationship (2) for a second value of cNB,WW2, which corresponds to 102% of the target value cNB,WW2,TARGET, and wherein the flow rate of the stripping gas is adapted to the flow rate of the wastewater WW1 such that the flow rate of WW1 is within a range of values (AB) that is generated by the first mathematical relationship (1) and the second mathematical relationship (2) at the respective flow rate of WW1, and controlling the concentration of nitrobenzene in WW2 (cNB,WW2) by adjusting the flow rate of stripping gas SG1 accordingly in the event of a measured actual value of this concentration which is outside a window of >98% to

摘要： A vapor distributor for use in an internal region of a mass transfer column to receive and redistribute a vapor stream when it is introduced radially into the internal region through a radial inlet in a shell of the mass transfer column. The vapor distributor includes a plurality of multiple-sided elongated deflectors arranged in a descending array and a pair of braces that extend longitudinally across the array of elongated deflectors and hold them in spaced apart and side-by-side relationship to each other. Each of the elongated deflectors has a deflecting surface that faces toward the radial inlet to redirect and redistribute the radially-introduced vapor stream. The braces each include a strut that may also redirect and redistribute the vapor stream.

摘要： A co-current contacting system is described herein. The co-current contacting system includes a co-current contactor located in-line within a pipe. The co-current contactor includes an annular support ring configured to maintain the co-current contactor within the pipe and a number of radial blades configured to allow a liquid stream to flow into the co-current contactor. The co-current contacts also includes a central gas entry cone configured to allow a gas stream to flow through a hollow section within the co-current contactor, wherein the co-current contactor provides for efficient incorporation of liquid droplets formed from the liquid stream into the gas stream. The co-current contacting system also includes a separation system configured to remove the liquid droplets from the gas stream.

摘要： In existing structured packing, performance depends on effective contacting area. Performance decreases in cases having high surface tensions such mixtures containing a lot of water. Such mixtures are difficult to wet the packing surface. The present invention prevents liquid from intersecting the crease of the corrugation and from falling into a free space. Further, liquid flowing into the slot makes frequent liquid and vapor interfacial update resulting in positive utilization of the wetted area. The most important point of this invention is taking a large value of 3.5 or more of P/H (pitch/height of the crimp) and providing the horizontal slot on the crease, resulting in adding the flow reversal mechanism and frequent interfacial update.
摘要翻译：在现有的结构化包装中，性能取决于有效的接触面积。在具有高表面张力的情况下性能下降，这种混合物含有大量的水。这种混合物难以润湿包装表面。本发明防止液体与波纹褶皱相交并落入自由空间。此外，流入狭槽的液体使液体和蒸气界面更新频繁，导致润湿区域的积极利用。本发明的最重要的一点是要获得3.5以上的P / H（压接高度），并且在折痕上提供水平槽，从而增加流动反转机构和频繁的界面更新。
