چکیده
The scale of CO2 emissions from light-duty vehicle (LDV) fleets worldwide has led governments to mandate substantive improvements in fuel economy, thereby mitigating climate change. Raising the Research Octane Number (RON) through isomerization, alongside mandates recalibrate existing LDV engines, promises contribute substantially action. This study aimed develop a highly efficient adsorption separation technology for isomerization refining that can significantly sustainability and economics overall “well-to-wheel” outcome globally. developed rigorous dynamic model Simulated Moving Bed (SMB), comparing SMB conventional distillation as next best alternative. was optimized using genetic algorithm, maximizing RON Gross Margin objective functions. showed effectively separates high octane components low components, producing with 95 when RON, enabling lower associated recalibrated engines. Compared 11 MW steam duty distillation, unit utilized 3.4 5.7 electricity optimizing respectively, appreciably reducing comparative greenhouse gas emissions. Finally, compared measured by Margin, increased economic return 47% 82 % Margin. In summary, this motivated rapid capital investment into retrofitting facilities operations, replacing outmoded primary technology. Future work will focus on process techno-economic analysis function optimization.

In this article, the performance of a reactive Simulated Moving Bed (SMB) and its modification, the more flexible Varicol process, is improved for the synthesis of methyl acetate (MeOAc) ester by multi-objective optimization using Non-dominated Sorting Genetic Algorithm (NSGA). The Varicol process is based on a non-synchronous shift of the inlet and outlet ports instead of the synchronous one u...

The performance of the simulated moving bed (SMB) technology and its modification, the Varicol process, was optimized using an experimentally verified model for the enantioseparation of SB-553261 racemate. Single and multiobjective optimizations have been carried out for both existing as well as design stage and their efficiencies were compared. The optimization problem involves a relatively la...
