10The oxidative desulphurization (ODS) of light gas oil (LGO) is investigated with an in-house designed cobalt 21In order to develop a useful model for simulation, control, design and scale-up of the oxidation process, 22accurate evaluation of important process parameters such as reaction rate parameters is absolutely essential. 23For this purpose, the parameter estimation technique available in gPROMS (general Process Modelling 24 System) software is employed in this work. With the estimated process parameters further simulations of the 25 process is carried out and the concentration profiles of dibenzothiophene within the reactor are generated. 26

“…A number of technologies [3,4] have been developed over these years, including thermal coking, fluid catalytic cracking, hydrocracking and solvent deasphalting. Among them, solvent deasphalting process has attracted more attention for which can remove asphaltenes and metal compounds effectively from heavy crudes and provides a better quality of deasphalted oil for further upgrading.…”

“…A classical model for the chemical engineering process which comprises chemical kinetics, physical property interactions, mass and energy balances is made up of a number of differential as well as algebraic equations for both dynamic and steady state processes [ 16 , 17 ]. Some researchers considered the polyolefin reactor as a well-mixed reactor and only proposed a purely mathematical model where the temperature and monomer concentration in the reactor were calculated [ 18 – 20 ].…”

Polypropylene Production Optimization in Fluidized Bed Catalytic Reactor (FBCR): Statistical Modeling and Pilot Scale Experimental Validation

Propylene is one type of plastic that is widely used in our everyday life. This study focuses on the identification and justification of the optimum process parameters for polypropylene production in a novel pilot plant based fluidized bed reactor. This first-of-its-kind statistical modeling with experimental validation for the process parameters of polypropylene production was conducted by applying ANNOVA (Analysis of variance) method to Response Surface Methodology (RSM). Three important process variables i.e., reaction temperature, system pressure and hydrogen percentage were considered as the important input factors for the polypropylene production in the analysis performed. In order to examine the effect of process parameters and their interactions, the ANOVA method was utilized among a range of other statistical diagnostic tools such as the correlation between actual and predicted values, the residuals and predicted response, outlier t plot, 3D response surface and contour analysis plots. The statistical analysis showed that the proposed quadratic model had a good fit with the experimental results. At optimum conditions with temperature of 75°C, system pressure of 25 bar and hydrogen percentage of 2%, the highest polypropylene production obtained is 5.82% per pass. Hence it is concluded that the developed experimental design and proposed model can be successfully employed with over a 95% confidence level for optimum polypropylene production in a fluidized bed catalytic reactor (FBCR).
