Prepare the simplest principal type of flowsheet for the following process, and indicate the flowrates of the principal chemical components: A refinery stream containing paraffins and a mixture of aromatics (benzene, toluene, xylene, and heavier aromatics) is extracted with a liquid solvent to re- cover the aromatics. The solvent and aromatics are separated by distillation, with the solvent recycled to the extraction column. The aromatics are separated in three columns, recovering benzene, toluene, and mixed xylenes, in that order. The feed stream consists of the following: paraffins benzene 300,000 kg/h 100,000 kg/h 180,000 kg/h 70,000 kg/h 40,000 kg/h toluene xylene heavy aromatics

Problem 3 Prepare the simplest principal type of flowsheet for the following process, and indicate the flowrates of the principal chemical components: A refinery stream containing paraffins and a mixture of aromatics (benzene, toluene, xylene, and heavier aromatics) is extracted with a liquid solvent to re- cover the aromatics. The solvent and aromatics are separated by distillation, with the solvent recycled to the extraction column. The aromatics are separated in three columns, recovering benzene, toluene, and mixed xylenes, in that order. The feed stream consists of the following: paraffins benzene 300,000 kg/h 100,000 kg/h 180,000 kg/h 70,000 kg/h 40,000 kg/h toluene xylene heavy aromatics A 3-to-1 weight ratio of solvent to aromatics is used.
