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： 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.
