Engineering & EPC
Test the chemistry before the design is fixed
Complex chemistry can shape a project long before equipment is specified. OLI gives engineering teams a rigorous way to test how fluids will behave as the design develops, so important assumptions can be challenged while there is still time to change them.
The chemistry behind the design basis
Every project starts with a picture of how the process should behave. As the design matures, that picture becomes harder to change. In electrolyte systems, shifts in composition or operating conditions can move the chemistry away from the assumptions behind the flowsheet, materials or operating envelope. Understanding those differences early gives engineering teams a stronger basis for the decisions that follow.

Chemistry through the engineering lifecycle
Chemistry becomes harder to change as the design matures. Bringing it into the project early means assumptions can be tested before they become part of the design basis.
Challenge the process basis
Early studies are where feed and process assumptions are easiest to test. Feed variability and what-if cases can reveal where the design is sensitive to chemistry before the flowsheet begins to harden.
Validate the chemistry behind the design
By FEED, chemistry is starting to define the process basis and material requirements. Full electrolyte flowsheets can test how the proposed design behaves across the expected operating range before assumptions become specifications.
Keep the model aligned with the design
As stream data and operating conditions become better defined, the chemistry model can mature with them. Updating the same basis as the design progresses means new questions can be answered without reopening the study from the beginning.
Compare the design basis with reality
Once the plant is running, actual stream data can be compared with the original model to understand where conditions have moved and what that means for performance. Automated monitoring can extend that validated chemistry into ongoing operation.

Engineering questions shaped by chemistry
Different projects arrive at OLI with different questions. The common thread is the need to understand what the chemistry will do under the conditions the design creates.
Stream Characterization
Build a realistic picture of the stream and how its behaviour changes across the expected operating range.
Process Chemistry
Test how speciation and phase behaviour affect the process before they become fixed assumptions in the flowsheet.
Water Chemistry
Understand how process and utility water chemistry influences treatment and downstream behaviour.
Scale
Evaluate mineral solubility and identify where deposition risk can emerge as conditions change.
Corrosion
Relate fluid chemistry to material performance so alloy decisions reflect the environment the asset is expected to see.
Automation
Reuse validated chemistry in repeated calculations and connected engineering workflows without rebuilding the analysis each time.

The earlier chemistry is considered, the more useful it becomes to the design. It gives the engineering team time to challenge an assumption, rather than explain the consequence after it has been fixed.

Chemistry applied to engineering decisions
The strongest proof is where the model changes the basis of a real engineering decision.
Materials selection
Test the alloy against the environment
Working with DNV GL, OLI combined physical modeling with experimental data to assess alloy performance under severe conditions and support materials selection.
Process design
Model the brine before scale-up
In direct lithium extraction work, reaction kinetics and real brine chemistry were used to examine how plant conditions could influence lithium recovery before design assumptions were fixed.
CO₂ injection
Match materials to the expected chemistry
OLI modeling showed how injectate composition and formation water can change corrosion behaviour across candidate alloys, supporting material selection for CO₂ injection.

The OLI solution
Rigorous chemistry within the engineering workflow
The chemistry model doesn’t need to sit apart from the engineering model. OLI can be used directly for detailed analysis and process simulation, or within many of the software environments already used by engineering teams. OLI technology brings rigorous electrolyte thermodynamics into established process simulation workflows through integrations with:
Aspen Plus and Aspen HYSYS
Honeywell UniSim Design
gPROMS
KBC Petro-SIM
AVEVA PRO/II
SysCAD
METSIM
Define the chemistry behind the process
From a focused stream or materials question to a complete process flowsheet, OLI provides a rigorous environment for testing how electrolyte chemistry behaves as the design develops.
Use OLI where the project needs it
OLI can work within the engineering environment already in use, support connected and automated applications, or bring OLI specialists directly into more complex project questions. The approach can fit the way the engineering team needs to work.
OLI Engine
Use OLI thermodynamics within established process simulation environments.
API
Bring the same chemistry into automated and connected engineering workflows.
Consulting
Where a project requires deeper investigation, OLI specialists can work directly with engineering teams to develop and apply the appropriate chemistry model.
