Aspen Hysys, Cumene, Reaksi, Optimalisasi, UtilitasAbstract
The simulation process of cumene production is gaining importance as the industry strives to enhance efficiency and reduce production costs. In the era of technological advancements, the utilization of computer software such as ASPEN HYSYS has enabled a comprehensive analysis and optimization of the production processes. The materials, unit operations and processes involved are identified from Badger Technology. Each unit is meticulously analyzed and various parameters are fine-tuned to achieve optimal performance. The alkylation reaction between benzene and propylene is carried out by a zeolite catalyst. The simulated flowsheet demonstrates a satisfactory convergence, indicating an efficient process design. With a propylene flow rate of 100 kmol/hour and a B/P molar ratio of 7, 91.9 kmol/hour of cumene can be produced with a purity of 99.96%-mol. The preliminary utility consumption obtained from the simulation consists of approximately 7.08 ton/h of steam and 379.71 tons /h of cooling water. There was no significant effect of 1-6% propane impurity on the designed cumene production system. The selectivity of cumene obtained is at a high value of 0.87, while the percentage conversion of propylene to cumene obtained is at a high value of 93.68%. With the shortcut distillation fitur, the optimum number of stages required for the benzene and cumene columns was 18 stages and 20 stages respectively.
