| چکیده | ||
| In this work, a modified equilibrium approach based on calculation of multicomponent efficiencies is implemented for packed columns simulation. In this modified approach, distillation process non-idealities due to interphase mass transfer are considered while the algorithm remains simple and efficient. The whole method consists of a segment wise procedure which is performed iteratively in a computational MATLAB code to simulate an experimental packed distillation column with structured packings. In each iteration, the component efficiencies are determined to consider mass transfer effects through the packed segments. According to obtained profiles for temperature and component compositions, good agreement is observed between reported experimental data and simulation results, so that the average deviations are about 0.5% and 19% for temperature and compositions, respectively. This confirms that the presented modified equilibrium model can properly predict the performance of multicomponent distillation in the packed columns and therefore it can be employed as a valid and reliable tool for design and simulation of real distillation towers. | ||
