- Evaluate how deep learning and reinforcement learning optimize a process unit
- Assess where Imubit fits among process-control technologies
What Is Imubit?
Imubit is an American industrial-AI company that pioneered closed-loop AI optimization for refineries and chemical plants. Most plant analytics tools stop at advice — they tell an engineer what to change, and a human decides whether to act. Imubit goes further: its platform, the Optimizing Brain, learns a model of an entire process unit and then controls it directly, writing optimized setpoints back to the plant's control system in a continuous loop.
The approach earned its own category from industry analysts: Closed Loop AI Optimization. The distinction matters because the value of optimization compounds when it runs continuously and automatically, rather than depending on an operator to notice and act on each recommendation.
💡Key Concept
Closed loop versus open loop: In an open-loop tool, the AI advises and a human acts. In a closed loop, the AI's decisions are sent straight back to the controls and executed automatically, within safety limits. Closed-loop systems capture far more of the available benefit because they act on every opportunity, around the clock.
How AI Changes the Workflow
Imubit builds what it calls a Foundation Process Model — a deep neural network trained on a plant's historical operating data to capture how the unit actually behaves, including the complex, nonlinear interactions that first-principles models struggle with. Reinforcement learning then searches for the operating strategy that maximizes an objective — yield, energy efficiency, or throughput — while respecting the plant's constraints. The result runs in closed loop, continuously nudging the unit toward its best achievable operating point.
For engineers, this shifts the work from manually chasing optimization opportunities toward defining objectives and constraints, validating the model, and supervising its performance. Imubit reports deployment across many of the largest refiners in the United States, along with customers in chemicals and cement.
Who Uses Imubit?
Imubit targets refineries and chemical and process plants where units are complex, continuously operated, and energy-intensive — exactly the conditions where small, sustained improvements in control translate into large financial gains. Its customers are typically large processing operators looking to push optimization beyond what conventional advanced process control delivers.

Strengths
- True closed loop — acts on every opportunity automatically, not just advising
- Learns real behavior — a deep model captures nonlinear interactions first-principles models miss
- Continuous optimization — compounds value by running around the clock
- AI-native — built around deep learning and reinforcement learning, not bolted on
- Proven in refining — adopted across many of the largest US refiners
Limitations and Considerations
- Data-dependent — needs substantial historical operating data to train an accurate model
- Safety-critical — closed-loop control requires rigorous constraints and validation
- Best for complex units — value is highest on energy-intensive, continuously run processes
- Enterprise engagement — sold as a platform plus services, with custom pricing
