Most comprehensive electrolyte property database for thermophysical modeling Over 6,000 species and covers 80 elements of the periodic table and their binary and multicomponent combinations to address a very broad of operating conditions and industrial applications. Unparalleled accuracy for complex mixtures in a broad range of conditions The OLI property database represents over five decades of research innovation under various government and commercial research programs and contains thousands of mixtures, millions of experimental data points and dozens of properties with extensive experimental validation. Overview of OLI Property Databases At OLI, our databases reflect rigorous research and custom solutions. The Public Databases, foundational to our software, provide dependable insights from peer-reviewed data across a wide spectrum of chemicals and species. Our Engineering/Local Model Databases cater to immediate engineering challenges, offering crucial estimations even when comprehensive data is lacking. Developed by our Engineering team, often in collaboration with clients, they should be used with caution due to potential variances from peer-reviewed standards of our public databases. Additionally, we offer tailored Private Databases for specific client needs, emphasizing utmost confidentiality and clear contractual arrangements.
Objective Cooling towers are critical to industrial operations, but their management often suffers from limited visibility, unreliable measurements, and vendor-driven decisions. OLI’s Cooling Tower Digital Twin pilot solution integrates OLI Flowsheet: ESP, the OLI Process API, and machine learning (ML) to create a smart, self-optimizing digital twin of your cooling tower system. This unified platform empowers operators with actionable insights to reduce costs, improve reliability, and enable informed water chemistry decisions. OLI Solution: Digital Twin Powered by First-Principles Thermodynamics and ML Machine Learning – Bridging Data Gaps Data gaps are inevitable—pH meters drift, sensors fail, and some ions are rarely measured. This is where ML can serve as a soft sensor for pH and other unmeasured variables. In OLI’s cooling tower solution: - A Partial Least Squares (PLS) model built with the PLSRegression module from scikit-learn¹⁻³ predicts critical values like pH using reliable proxies (such as conductivity) - Enables accurate scaling and precipitation risk assessment even when pH data is incomplete - Supports hybrid modeling: using both measured and predicted values for higher model confidence This ML model is trained on plant-specific historical data and several pieces of analytical data from the lab. Hybrid Model Workflow 1. The trained PLS model predicts pH. 2. Process API runs the water analysis at the specified pH and ionic composition. 3. This reconciled water stream enters the full system simulation in Process API, which runs the cooling tower model previously built in Flowsheet: ESP. 4. An optimization calculation recommends the optimal blowdown rate for minimizing scale risk. Benefits to Users - Optimized Water and Chemical Use: Control CoC dynamically, based on real-time risk—not guesswork. - Robust real-time predictions of scaling based on live operating conditions, even under the limiting factors of poor physical sensors, missing data, or infrequent water analysis. - Seamless Integration: Designed to work with any historian or dashboard system. - Insights into Tower Health: Quickly compare how your tower is performing against internal KPIs and design values to assess the efficiency of your system. - Identify areas of improvement and optimize tower performance. OLI’s Commercial-off-the-Shelf (COTS) Cooling Tower solution features an intuitive interface that highlights key variables such as CoC, scaling risks, and optimal blowdown.

Continuous Visibility into Corrosion Behavior OLI TrueCORR™ transforms live plant data into continuous corrosion intelligence, helping teams understand when process conditions are creating real integrity risk and which operational changes can reduce exposure before corrosion escalates. Corrosion Risk Does Not Wait Most corrosion programs rely on static integrity limits and periodic inspection data from isolated points. This leaves teams uncertain whether changing operating conditions signal a true integrity threat or routine noise. Because corrosion exposure is multi-variable and inspection coverage is limited, teams often respond conservatively, even when existing historian, alarm, and operating data could provide clearer insight. The Chemistry Behind Corrosion Exposure OLI TrueCORR is built on decades of first-principles corrosion chemistry modeling, enabling the conversion of live operating chemistry into corrosion rate, dominant corrosion drivers, remaining life, and integrity limit status. Instead of relying on threshold alarms or historical failure patterns alone, OLI TrueCORR evaluates whether the active process environment is genuinely creating corrosive conditions. It also allows OLI TrueCORR to work beyond failure history, supporting assets where operating conditions have changed or historical corrosion data is limited. Calculate the actual corrosion risk OLI TrueCORR calculates corrosion risk directly from process chemistry and plant metallurgy, helping teams understand when changing operating conditions are materially increasing integrity exposure. Identify the corrosion driver The model shows which chemistry is causing the risk, so teams can act on cause rather than symptom.
