PEREZ SANCHEZ, Amaury; RANERO GONZALEZ, Elizabeth; PEREZ SANCHEZ, Eddy. J.  e  LIANO ABASCAL, Norlem. Simulation of the cumene production process by using ChemCAD® simulator. Rev. cienc. tecnol. [online]. 2020, n.33, pp.1-10. ISSN 1851-7587.

In the present work, the simulation of the cumene production process was carried out from the benzene alkylation with propylene by using the ChemCAD® simulator version 5.2.0. Heat curves of each shell and tube heat exchanger were obtained. At the same time, the composition and mass flowrate of each stream involved in the process were calculated. A sensitivity study was also carried out in order to know the influence of the flash vessel operating pressure on the amount of cumene to be obtained by the stream at the bottom of this equipment. 13 403.54 kg/h of cumene are obtained at the top stream of the second distillation column (cumene column), with a purity of 98.6%, being benzene (1.2%) the main impurity found in this stream. The flash vessel must operate at a pressure of 7 atm to obtain the best yield of cumene in this equipment.
