The further increase of the number of reactors in a cascade does not make any economic sense. Wherein the optimal reaction mixture temperature in all reactors of cascade is 372 K. It was shown that for cumene oxidation the cascade of three bubble column reactors is optimal from the point of view of the minimum value of the TAC. Design of cumene oxidation was carried out from the point of view of finding a compromise between the values of cumene conversion, selectivity and the minimum of total annual cost per unit of the target product (TAC). The Arrhenius parameters of the reaction rate constants of cumene oxidation were determined as a result of solving inverse kinetic problem. Access date: Dec-14-2017.The kinetics of cumene oxidation was investigated in a bubble column reactor at different temperatures of the reaction mixture in the range 378−403 K.

The obtained results validate the proposed methodology and will allow dynamic simulation of the process.ĭigital Object Identifier (DOI): doi.org/10.5281/zenodo.1340428 Procedia APA BibTeX Chicago EndNote Harvard JSON MLA RIS XML ISO 690 PDF The second major element of the article is the development of the methodology and the elaboration of the simulation program for the crude distillation process, using Unisim Design resources. A first aspect developed by the authors is the implementation of specific problems of petroleum liquid-vapors equilibrium using Unisim Design simulator. Analysis of the simulators for the crude distillation process has allowed the authors to elaborate the conclusions of the success of the crude modelling.
#UNISIM DESIGN DOWNLOAD SIMULATOR#
In order to use the Unisim Design simulator to simulate the crude distillation process, the identification of the simulators used in Romania and an analysis of the PRO/II, HYSYS, and Aspen HYSYS simulators were carried out. The necessity of simulating this process is argued both by considerations related to the design of the crude distillation column, but also by considerations related to the design of advanced control systems. The paper deals with the simulation of the crude distillation process using the Unisim Design simulator.
