Forced periodic operations of a chemical reactor for methanol synthesis – The search for the best scenario based on Nonlinear Frequency Response Method. Part II Simultaneous modulation of two inputs

The analysis of the potential to improve performance a methanol synthesis reactor through forced periodical operations by Nonlinear Frequency Response method is presented. in an isothermal and isobaric lab-scale CSTR considered. First, was performed for single input modulations (in Part I), which showed that significant improvements can’t be achieved. Here, study extended simultaneous two inputs. All possible combinations (6 cases) are analysed optimal forcing parameters, maximizing time-average production, were determined. For all improvement possible, but some cases it not significant. highest predicted modulation inlet partial pressure CO volumetric flow rate. This case, achieve up 33.51 % detail optimized using multi-objective optimization.
