摘要： One exemplary embodiment can be a process for separating a plurality of naphtha components. The process can include first and second columns. The first column may include a dividing imperforate wall with one surface facing a feed and another surface facing a side stream. Typically, the wall extends a significant portion of the column height to divide the portion into at least two substantially vertical, parallel contacting sections. Also, the second column can communicate with the first column so as to provide a feed to or receive a feed from the first column. Generally, the second column is non-divided. The process may provide at least four product streams.

摘要： An aromatics complex producing one or more xylene isomers offers a large number of opportunities to conserve energy by heat exchange within the complex. One previously unrecognized opportunity is through providing two parallel distillation columns operating at different pressures to separate C8 aromatics from C9+ aromatics. The parallel columns offer additional opportunities to conserve energy within the complex through heat exchange in associated xylene recovery facilities.

摘要： Hydrocarbon feed to a catalytic reactor can be heat exchanged with flue gas from a catalyst regenerator. This innovation enables recovery of more energy from flue gas thus resulting in a lower flue gas discharge temperature. As a result, other hot hydrocarbon streams conventionally used to preheat hydrocarbon feed can now be used to generate more high pressure steam.

摘要： Methods for controlling the operation of fractionation columns to avoid column flooding are described. The methods use mass flow meters to measure the mass flow rates of the receiver vapor, and the stripper hydrocarbon liquid or stripper reflux and stripper net overhead. The water from the receiver can be measured with either a volumetric flow meter or a mass flow meter. A computer can be used to determine the dew point from the mass flows, and an alarm can be triggered and/or a process change can be made if the difference between the calculated dew point and the temperature of the overhead vapor stream is less than a predetermined amount.
