Question
### Problem Statement A complex mixture of aromatic compounds leaves a chemical reactor and is fed to a distillation column. The mass fractions and flow rates of distillate and bottoms streams are given in Table 4.25. Compute the molar flow rate and composition, in molar fractions, of the feed stream. ### Table 4.25: Flow Rate and Composition of Distillate and Bottoms Streams | Stream | Flow Rate (kg/h) | ω<sub>Benzene</sub> | ω<sub>Toluene</sub> | ω<sub>Benzaldehyde</sub> | ω<sub>Benzoic Acid</sub> | ω<sub>Methyl Benzoate</sub> | |------------|------------------|---------------------|---------------------|--------------------------|--------------------------|-----------------------------| | Distillate | 125 | 0.1 | 0.85 | 0.03 | 0.0 | 0.02 | | Bottoms | 76 | 0.0 | 0.05 | 0.12 | 0.8 | 0.03 | ### Explanation The table provides data on the flow rates and mass fractions for different aromatic compounds in both the distillate and bottoms streams. The compounds include Benzene, Toluene, Benzaldehyde, Benzoic Acid, and Methyl Benzoate. The flow rate is measured in kilograms per hour (kg/h), and the mass fractions (ω) indicate the proportion of each compound in the respective streams.
