OVERVIEW
Versatile capability to simulate complex environments
Nature is infinitely complex and we have to deal with multicomponent, multiphase systems that contain electrolytes and non-electrolytes. We need to cover wide ranges of temperatures—from cryogenic conditions to high temperatures in boilers—and deep well environments. The concentrations of interest can vary from extremely dilute solutions of toxic contaminants to very concentrated salt solutions or even pure acids or ionic liquids.
Aqueous Model
A reliable, time tested legacy model that covers a wide range of components in systems dominated by water.
MSE Model
The state of the art model for mixtures containing any combination of electrolytes and nonelectrolytes without concentration limits.
MSE-SRK
A special version of the MSE model maximizes accuracy for upstream oil and gas applications.
MSE corrosion model for CRA
The OLI MSE (Mixed Solvent Electrolyte) corrosion model is a sophisticated tool developed for predicting corrosion in a variety of environments, including non-aqueous systems. This model utilizes the MSE framework to accurately predict chemical and phase equilibria in complex systems.
