Process Simulation & Scale-Up Consultant, PhD Chemical Engineer, Expert in Process Simulations & Membrane Technologies

プロフィール概要

I am a PhD-trained Chemical Engineer with extensive experience in process simulations, process design, and scale-up of chemical and membrane-based systems. My background spans both academic research (PhD + postdoc) and industrial applications, enabling me to bridge scientific innovation with practical engineering solutions. Currently, I work as a Senior Process Specialist at TreeToTextile AB (Sweden), where I lead optimization and design of chemical recovery, liquid/solid waste management, and process scale-up. I also coordinate collaborative projects with Chalmers University of Technology, establishing process laboratories and designing experimental setups. Core expertise and skills : Process Simulation & Design: Custom simulation tools. Process Scale-Up: From lab-scale experiments to pilot and industrial plants. Membrane Technologies: Nanofiltration, separation processes, crystallization of heavy metals. Chemical Recovery Systems: Evaporation, washing, dissolution, and concentration processes. Data-Driven Modeling: Statistical analysis, calibration models, and dimensional analysis for viscosity/density prediction. Molecular and Quantum Simulations: GROMACS, QUANTUM ESPRESSO Previous & Ongoing Projects: Developed proprietary simulation software for chemical recovery systems (evaporation, crystallization, nanofiltration). Designed and optimized membrane-based processes for selective separation of solutes. Investigated mass transfer and washing efficiency in pulp and cellulose fiber processing. Built calibration models for process instruments (Coriolis meters, viscometers) linking physical properties to concentration and flow conditions. Led cross-functional R&D teams for scale-up and commissioning of novel processes. With a strong combination of academic depth and industry experience, I provide consultancy to help companies and researchers design, optimize, and validate chemical processes that are both innovative and industrially viable.
