• Government programs and policies are getting launched to address these global crises such as "Make in India", smart city, net zero, etc. so there will only be more opportunities.

To conclude, the chemical engineer of today is not simply a plant operator, they are a problem solver, data interpreter, and global climate hero.

The Transformation of Chemical Engineering

Chemical engineering was at first only about developing and improving industrial processes with a goal of taking raw materials and turning them into useful products, processing oil into fuels and chemicals, making drug products and designing synthetic materials. Subsequently, it progressed to encompass developments in molecular engineering, nanotechnology and environmental sciences.  Currently, it is back in a state of transition, this time with AI, automation and digitalization.

More frequently, companies are investing in advances in AI chemical simulation software, which offers useful predictive modelling of chemical reactivity, reaction optimization, energy efficiency in production, and waste reduction.  Meanwhile, cloud and big data technologies are allowing engineers to follow and respond to the operations of plant equipment remotely, which improves efficiencies and reduces the risk of problems being developed into costly downtimes.  

In addition, due to the recent pressure of environmental issues impacting and influencing the chemical industry (specifically carbon capture, new green production methods for hydrogen, and sustainable polymers) chemical engineers are at the leading competitive edge to be able to positively contribute to more sustainable and resilient world utilizing their R&D background.

The future of the field is smart manufacturing, AI-driven chemical design, and circular economy solutions. For this reason, graduates in chemical engineering are not only resolving tough industrial problems; they are also a vital part of creating a greener and more sustainable world.

The Rise of Sustainable Process Engineering

Certainly, the largest shift occurring in chemical engineering is sustainability. We are rapidly transforming the world to respond to the existing demand for cleaner energy, waste reduction, and sustainable materials. Sustainable process engineering is evolving at a rate never before seen. 

Chemical engineers are developing:

1. Carbon Capture and Utilization - Several industries produce huge amounts of CO₂ emissions, but new and innovative chemical processes can capture CO₂ from the environment and convert it into useful products. 
2. Waste-to-Energy Technologies - In lieu of letting usable industrial waste become a nuisance for industries, new and innovative chemical processes can utilize waste to produce electricity or biofuels. 
3. Green Hydrogen Production - with hydrogen being one of the cleanest fuel alternatives available, chemical engineers are designing processes capable of producing hydrogen in the most efficient and sustainable way. 
4. Biodegradable Materials and Polymers - The fight against plastic pollution is, in many ways, being led by chemical engineers who are designing substitutes for plastics that are biodegradable. 

As industries are moving completely away from fossil fuels and harmful pollutants, chemical engineers trained in process design will continue to set the pace. Chemical engineering is no longer a discipline seeking to achieve sustainability in industrial processes - it is a discipline that is encouraging us to rethink how humanity interacts with the materials.

Artificial Intelligence and Digitalization in Chemical Engineering

Numerous processes within the broader scope of chemical engineering are being automated and/or using artificial intelligence (AI) technologies in ways that were unimaginable just maybe 10 years ago, as new technologies are evolving the foundations of chemical engineering to be more productive, safer and economical.

AI mediated Predictive Modeling - chemical engineers began to apply machine learning algorithms for outcome predictions based on what the material will do in various situations, how to optimize reactions, and find a new, safer way to produce a product. 

Digital Twins - digital twin technology provides chemical engineers with simultaneous virtually always-on models of an industrial process. A virtual model can track an industrial process live, with the ability to make adjustments if it detects possible failure points or improvements in production.

Robotics - robotics can now be used in laboratories and production plants to handle substances that are considered dangerous to human health with much less risk and precision.

Big Data Streaming - the ability to capture, process, and analyze vast amounts of industrial data helps identify efficiencies, outliers, and tightened supply chains.

Digitalisation is not removing the job of a chemical engineering but augmenting it. The future engineer will need to know how to use the artificial intelligence and data analytics and automation alongside the knowledge they will still need to develop in conventional engineering practice.
