Process Simulation Expert | Aspen HYSYS & Aspen Plus | 15+ Yrs Chemical Engineering Consulting

Profile Summary

I am a chemical engineer and process simulation specialist with over 15 years of experience in Aspen HYSYS and Aspen Plus, spanning industrial consulting, academic instruction, and technical training. My core expertise lies in steady-state and dynamic process simulation, distillation and reactive distillation design, heat exchanger network (HEN) synthesis and pinch analysis, mass and energy balance modeling, and process optimization — including hybrid simulation-optimization workflows coupling Aspen Plus with MATLAB (e.g., NSGA-II multi-objective optimization). My professional background includes plant-side process engineering experience at Bioenergy Arabia, where I worked on catalyst regeneration and process troubleshooting for a DMF production facility, and academic instruction at King Fahd University of Petroleum and Minerals (KFUPM), where I taught process simulation and chemical engineering design courses. Through my consulting practice, I have supported clients on CSR data analytics and infrastructure prioritization dashboards, seawater cooling system design for data center applications, and centrifugal pump sizing and selection. I also founded DOSENTEKIM, a chemical engineering education platform, through which I have produced technical training materials, simulation guides, and hands-on Aspen HYSYS/Aspen Plus workshops for engineering students and early-career professionals across Indonesia. I offer services in: process flowsheet development and simulation (Aspen HYSYS/Aspen Plus), column and reactor design and troubleshooting, thermodynamic package selection, HEN synthesis and energy integration studies, simulation-based optimization (MATLAB/Python), technical documentation and simulation training, and engineering data analysis. I deliver rigorous, well-documented technical work suited for both industrial and R&D/academic clients, with clear assumptions, validated results, and reproducible workflows.
