KWA Kenwalt Australia and OLI partner for ALTA 

May 2018

OLI has partnered with KWA Kenwalt Australia in bringing rigorous chemistry analysis to SysCAD, a heat and material balance flowsheet simulator for mineral processing. Using the OLI Engine: Developer Edition, KWA developed an OLI reactor block within SysCAD that will allow OLI properties to be calculated as one of the blocks in the traditional SysCAD flowsheet. This combines the best of both packages for a strategic offering available through either company.

MSE SRK: A new electrolyte thermodynamic model 
January 2018

OLI is introducing the MSE-SRK thermodynamic model.  This model is a combination of MSE (Mixed Solvent Electrolytes) for electrolyte systems and SRK (Soave-Redlich-Kwong) for the gas phase and the second liquid, or non-electrolyte phase. The MSE-SRK model is targeted at oil and gas production and will address the limitation in the MSE model when handling supercritical components at elevated pressures, as well as the MSE phase discontinuities for mixtures containing supercritical components at transition points between vapor-liquid and liquid-liquid equillbria.

OLI Chemistry in Refining Overheads II - investigating further validation of the amine chloride chemistry

Updated January 2018

OLI and AQSim have initiated the Chemistry in Refining Overheads II program to commission measurements on selected amine hydrochlorides. These measurements will be used to validate the present OLI database for predicting amine-hydrochloride deposition or condensation. If and where discrepancies are found between the existing model predictions and the new laboratory measurements, the OLI database will be updated using the new measurements.

This resulting work, experimental data, and modified database will be held proprietary to members for a period of 18 months following program completion. 

This consortium started in June 2017; however you can join us too! The program is open to late-join members and your participation will allow us to expand the slate of amines we are investigating.

ScaleChem Standard has been replaced by OLI Studio: ScaleChem
Updated January 2017


OLI Systems, Inc. has announcing the end of sales for ScaleChem Standard, effective January 4, 2017. Maintenance support for existing ScaleChem Standard installations will be available until December 31, 2017.

OLI appreciates and supports the diversity of applications in our client base, and our strategy has been to support all products in our current product slate. However, ScaleChem Standard  is now twenty-year old software.  Its architecture and application are dated, and its features and functions do not effectively meet the increasingly technical needs of upstream users.  Most importantly it does not support our newest mixed solvent electrolyte (MSE) thermodynamic framework.

OLI strategy going forward is to develop advanced upstream applications and thermodynamics in OLI Studio: ScaleChem.  OLI Studio: ScaleChem has a modern and connected interface and has access to both AQ and MSE thermodynamic frameworks.  These improvements increase application purview, speed up case generation, and make it easier to interpret results; all of which increases productivity.

OLI awarded funding next year through Critical Materials Institute

June 2016   

OLI has just completed its third year of research within the framework of the Critical Materials Institute (CMI). CMI serves as a hub of the Department of Energy to spearhead research on rare earth elements. This research includes diversifying the supply of rare earths, developing efficient recycling processes and finding substitutes for the industry.


In a recent project, OLI provided thermodynamic support to study the effect of rare earth elements (REEs) on biological activity in wastewaters. Researchers from the Idaho National Laboratory (INL) are investigating if the presence of REEs can impair the functioning of waste treatment plants. The effect of REEs depends on their solubility. OLI’s MSE model has been used to predict the solubility and to see which stable or metastable solids can control the bioavailability of REEs. More details are available in this paper: (here a link to the nitrification paper).


In another project, researchers from the Lawrence Livermore Laboratory studied an innovative process to extract and recover REEs using genetically engineered bacteria. The bacterial cell surfaces are modified to include short peptides called the lanthanide binding tags, which preferentially bind REEs from aqueous solutions. After adsorbing the REEs, it necessary to strip them from the surface to design a practical separation process. Here, OLI’s MSE model has been used to understand the complexation of REEs, which is necessary for stripping. In agreement with the MSE predictions, citrate ions were found to be effective stripping agents. For more details, please see this paper: (here a link to the bioadsorption paper).


Other projects are under way and we will report on them in the near future.


Andre Anderko elected NACE Fellow

March  2016   

OLI’s Managing Director and Chief Technology Officer Andre Anderko has been elected a Fellow of NACE International. The honor of NACE Fellow is given in recognition of distinguished contributions in the field of corrosion and its prevention and to develop a broadly-based forum for technical and professional leaders to serve as advisers to the Association. As stated in the citation, Andre has been elected for his contributions to corrosion prediction through modeling the electrochemistry and corrosion in complex chemical processes.


James Feather, the President of NACE International, wrote: “The sustained contributions you have made to corrosion control have been well recognized over the years. It is obvious that the selection panel could not have made a better choice by selecting you as a NACE Fellow.”


The honor has been bestowed on Andre at the CORROSION 2016 conference in Vancouver on March 9, 2016.
