Built for process engineering


Compatibility
Kelden connects to Aspen Plus, Aspen HYSYS, Honeywell UniSim, AVEVA PRO/II, Siemens gPROMS, and DWSIM through the open CAPE-OPEN standard and authorized interfaces, so your validated models stay exactly where they are. There is no rip-and-replace, no re-validation, and no lock-in. It sits alongside your existing stack and makes it smarter from the first day.
Conversational modeling
Tell Kelden what you are trying to do in plain language and it constructs and modifies the flowsheet for you, setting up units, streams, and specifications the way an experienced engineer would. Hours of manual model building become a conversation, and you stay in control of every assumption along the way.


Optimization
Kelden continuously optimizes for what matters to you, balancing yield, throughput, energy, and emissions against real operating constraints. Real-time, planning, and design optimization all run on the same engine, and it surfaces the operating points that become measurable savings per site, the difference between a good plant and a great one.
Speed and fidelity
Kelden pairs rigorous first-principles models with machine-learned surrogates and reduced-order models, so you get the accuracy of fundamental engineering with the speed of AI. Expensive simulations that used to block optimization now run fast enough to optimize in the loop, without giving up physical fidelity.


Validated accuracy
Kelden runs on its own validated thermodynamic and physical-property foundation, cross-checked to within one to two percent of trusted reference results on target chemistry. The numbers hold up under scrutiny, whether you are sizing equipment, certifying a design, or defending an operating decision.
Live plant data
Connect Kelden to your historians and control data through the PI System, Aspen IP.21, and OPC UA, and it keeps your models calibrated to what the plant is doing right now. Optimization and planning run on current conditions instead of last quarter’s assumptions, so the answers reflect the plant you actually operate.


Safety and trust
Every recommendation is grounded in physics, verified against the numbers, and shown with the assumptions behind it, so your engineers can see exactly why before they act. Nothing moves from advice toward action without verification and human approval, with hard limits built in. Kelden is made for plants where being right matters.
Deployment
Deploy Kelden in the cloud, entirely on-premises, or air-gapped, to meet whatever your security and data-residency rules require. It is built to enterprise standards with role-based access, complete audit trails, and industrial cybersecurity alignment, so IT and OT can both sign off.


Decarbonization
Kelden treats energy and emissions as first-class objectives alongside yield and throughput, so you cut cost and carbon in the same decision. From hydrogen and carbon capture to biofuels and electrification, it is built for the processes defining the energy transition, including greenfield projects with no legacy to work around.
