The First Annual Webinar on Modeling Aqueous Systems: Fundamentals and Modeling Techniques with OLI Studios will take place June 22-26. This is an online workshop.
FUNDAMENTALS AND MODELING TECHNIQUES
This webinar will cover the fundamentals of modeling aqueous solutions and corrosion processes used within OLI Studio. Systems at elevated temperatures and pressures will be addressed. Lectures and hands-on OLI Studio modeling exercises will be used to demonstrate how complex systems can be modeled. This webinar is appropriate for those new to OLI Studio, professionals working with this software, and those looking for a refresher course in its underlying theory. Modeling walkthroughs will be presented using OLI’s Stream Analyzer, Corrosion Analyzer, and Studio ScaleChem programs.
