Electrolyte Based Modeling of Corrosion Processes in Sulfuric Acid Mixtures

September 2021

Sulfuric acid is a large volume chemical, with the world production estimated to be about 270 million metric tons in 2018.1 The need to reduce sulfur emissions from fossil fuel usage may be a driver for increased sulfuric acid production in the future. Sulfuric acid mixtures occur in many applications..


Mitigating rich HF corrosion in alklyation An OLI JIP proposal  

September 2018

Ideally, the Integrity Operating Window (IOW) for an HF alkylation unit would be fine-tuned by using process simulation in order to minimize HF corrosion. Rigorous process simulation could predict the thermodynamic phase change temperature and pressure of the streams in the unit and develop safe operating conditions. Join this new OLI JIP to develop the necessary parameters to permit accurate HF alklation modeling.

Screening alloys for produced water 

June 2018

Simulation can give a first level screening on alloy selection by calculating a corrosion rate of particular service in contact with a range of materials.  This Spotlight Video shows how to use the OLI Studio: Corrosion Analyzer to predict general and localized corrosion in commercial alloys exposed to various produced water environments, and how you can use OLI to help select the most appropriate material for your application.


Transforming electrolyte chemistry modeling applications

September 2021

The chemical engineering landscape is undergoing major shifts that are challenging companies to evolve their approach to technology, chemistry, and mathematics. With the development of new advances—such as the Internet of Things (IoT), process modeling and simulation software, advanced analytics, and more—the industry is realizing greater performance, yields, cost-efficiencies, and more widespread applications including faster time to market. 


Accelerate corrosion prediction accuracy with OLI technology

April 2018

OLI technology addresses corrosion caused by chemical attack. If you have a water-based system, or a gas system that has potential condensate, simulation can calculate: Corrosive environment simulation;  the tendency for corrosion; a kinetic rate of uniform corrosion; a localized corrosion indicator and worst case propagation rate; and, remaining asset life given pit depth and time information.

Simulating corrosivity in gas condensates  

March 2018

When there is water vapor in a gas line, the resulting condensate can be highly corrosive. Request this Spotlight Video to learn how to calculate when this phenomenon will occur.


Autoclave charging for corrosion testing 

September 2018

Using electrolyte simulation prior to performing an autoclave experiment can effectively ensure that the autoclave experiment input will more precisely match the target final conditions. In this OLI Spotlight Seminar, learn how to setup the configuration of your autoclave experiment and calculate the input conditions for our autoclave that will achieve the experiment target.


Mitigating corrosion in refinery overheads

August 2018

Corrosion in refining overheads as a common problem caused by phase changes in neutralizing amines. Learn how OLI software can calculate safe operating temperatures, by identifying the water dew point, the amine salt point and an ionic dew point for systems involving neutralizing amines
