Why AI Is a Big Deal for Petrochemical Plants
Ethylene is a building block for many everyday products, from plastics to textiles. Producing it efficiently and sustainably is critical for companies to stay competitive. Right now, several important factors are pushing companies to take AI seriously:
- Global competition means companies must operate as efficiently as possible.
- Environmental regulations are getting stricter, requiring cleaner, more sustainable operations.
- Modern plants are data-rich, thanks to advanced sensors and control systems that generate vast amounts of data daily.
This combination—pressure to perform, stay on NetZero targets, and make the most of data—creates the perfect environment for AI to thrive.
What Can AI Do in Ethylene Plants?
AI and machine learning (a type of AI that learns from data) can help plants improve in many ways, such as:
- Optimizing furnace and plant (including critical utility systems) operations to improve energy efficiency and boost output
- Predicting equipment failures before they happen, reducing unplanned shutdowns
- Managing energy use more effectively, which helps lower costs and emissions
- Improving product quality through better process control
- Enhancing safety by spotting issues earlier
These improvements aren’t just nice to have—they can deliver significant cost savings, improve reliability, and help meet sustainability goals.
But It’s Not Always Easy
Adopting AI isn’t as simple as flipping a switch, despite the benefits. There are real challenges that companies need to navigate:
- Data issues: AI needs good data to work well. It can't learn properly if the data is messy, missing, or scattered across systems.
- Lack of expertise: You need people who understand AI and plants' complex chemical processes. That’s a rare combination.
- Costs and time: Some leaders worry that AI projects will take too long or cost too much without guaranteeing results.
- Trust and transparency: Some AI models, especially the more complex ones, can feel like “black boxes.” If operators don’t understand how AI makes its decisions, they might hesitate to trust it, especially in safety-critical situations.
Overcoming these hurdles requires careful planning, the right team, and a commitment to learning.
What Makes AI Projects Succeed?
The successful AI applications in steam cracking share some common traits:
- Close teamwork between plant engineers and AI specialists. Engineers know the process, AI experts know the tech—it’s only by working together that the best solutions emerge.
- Clear goals. It’s essential to start with a clear problem to solve, like cutting energy use or reducing downtime.
- Pilot projects. Starting small with test projects lets companies prove what works before rolling it out across the plant.
- Continuous monitoring and data reliability: AI models must be checked and updated regularly to ensure they’re still accurate and helpful.
A Smart Way to Start with AI
For plant owners and managers thinking about using AI, here’s a good game plan:
1. Identify pain points. Where are your biggest inefficiencies or challenges?
2. Check your data. Do you have the right information to support an AI solution?
3. Evaluate ROI potential. Focus on areas where AI could deliver real value.
4. Run small-scale pilots. Test, learn, and refine before going big.
5. Invest in people and systems. Make sure your teams are trained and your infrastructure is ready.
AI can help Operate Smarter, Safer, Sustainable Plants
​
AI is not science fiction; it can help petrochemical companies run cleaner, safer, and more efficiently. From smarter steam cracker operations to predictive maintenance and better energy management, AI can bring real, measurable value.
Yes, there are challenges. But with the right strategy, tools, and people, companies can unlock AI's full potential. That means better performance, lower costs, and a stronger position in a competitive global market while moving toward a more sustainable future.
Bottom line: AI is becoming a key part of the petrochemical playbook. The companies that embrace it strategically today are setting themselves up for long-term success.
I'm not an AI expert, but I’ve read about it, spoken with experts, and followed the field closely. I also have hands-on experience applying machine learning, guiding an owner’s in-house statistical modeling team to build a predictive model of compressor behavior. This work involved understanding the core principles of machine learning and quickly making sense of messy, incomplete data under tight business deadlines.
