A report just released by the International Energy Agency states that mankind will soon be using more oil for making petrochemicals than it uses to make fuel. While most petrochemical oil is used on generating energy for chemical production, much is also used as a raw chemical feedstock. As the petrochemical market grows it will increasingly influence oil prices, will be less sustainable, and its impact on climate change will multiply.

As the IEA made clear in its recent press release, “Petrochemicals are set to account for more than a third of the growth in world oil demand to 2030, and nearly half the growth to 2050, adding nearly 7 million barrels of oil a day by then. They are also poised to consume an additional 56 billion cubic metres (bcm) of natural gas by 2030, and 83 bcm by 2050.”

The size and influence of the petrochemical industry is already far-reaching, touching every corner of modern life. Basic petrochemicals are used to make everything from detergents to clothing, digital devices and medical equipment, fertilizers, tyres and packaging.

But of all these products the report, entitled ‘The Future of Petrochemicals’, is quick to highlight how demand for plastics is making the biggest impact. The analysis states that the growth rate of plastic production has more than doubled since 2000. Furthermore, the report explains how this cannot be ascribed purely to increasing global wealth, as the data shows that the use of plastics is now outpacing the use of other modern bulk materials, such as steel, cement, and aluminium.

The report also warns that developed economies have become dependent on petrochemicals. But it also foretells that much of the increased oil consumption will come when developing countries begin to adopt the practices of richer populations.

As the report writes, “Advanced economies currently use up to 20 times more plastic and up to 10 times more fertiliser than developing economies on a per capita basis, underscoring the huge potential for global growth.”

Additionally, the need to produce more food will be another factor driving demand for oil and gas. With global population predicted to reach 9.7 billion by 2050, the use of fossil fuels in the Haber-Bosch process for fertilizer production will also play a part in growing oil consumption.

The consequences of these trends will be far reaching, effecting the ozone layer, air quality, landfill sites, ocean waste, and climate change. As Kendra Pierre-Louis, of the NY Times reports, “Petrochemicals are currently the largest industrial energy consumer and the third-largest industrial emitter of greenhouse gas emissions. The report found that direct greenhouse gas emissions from petrochemicals would increase 20 percent by 2030 and 30 percent by 2050.”

Adding that, “The main driver of the petrochemical industry’s growing climate footprint will be plastics. Worldwide, roughly 300 million metric tons of plastic are produced each year.”

The increase in oil consumption is an unsustainable trend, but the petrochemical industry’s role in that growth has largely stayed out of the public limelight.

As Dr Fatih Birol, the IEA’s Executive Director, notes, “Our economies are heavily dependent on petrochemicals, but the sector receives far less attention than it deserves. Petrochemicals are one of the key blind spots in the global energy debate, especially given the influence they will exert on future energy trends. In fact, our analysis shows they will have a greater influence on the future of oil demand than cars, trucks and aviation.”

While great progress has been made to lessen oil-dependency in other industries, the chemical industry has yet to follow suit. For example, the transport industry has come a long way to reduce oil consumption, with more efficient engines, lighter cars, increased use of biofuels, and the development of electric cars. The energy industry has invested heavily in alternative supply sources such as wind, wave, and solar, while the construction industry has developed homes that are much better insulated.

Meanwhile, in many ways the petrochemicals industry has escaped public and political scrutiny and has therefore failed to develop more sustainable chemical feedstocks.

Ironically however, sometimes it is the increased role of oil-based plastics in other industries that has helped them to lessen their fuel consumption. For example, modern cars are lighter as so many parts are made from plastic or plastic composites. Similarly, solar panels and wind and wave turbines are also made with plenty of plastic, while plastic windows and petrochemical foams and insulants have reduced heating costs.

However, this is not to excuse the responsibility that the petrochemicals industry has in lessening its oil dependency.

As the online scientific journal Futurism, notes, “Decreasing emissions in the transportation and energy sectors while increasing the carbon footprint of plastics and other chemicals isn’t exactly a win for the environment.”

However, the comparison is stark. What other historically oil-dependent industries have achieved shows the change that is possible. The chemical industry has invested in alternative raw materials, but has yet to make them mainstream. Perhaps reports like this, and the recent report on global warming by the UN’s Intergovernmental Panel on Climate Change (IPCC), will give us all the impetus to push for more and more sustainable chemical raw materials.

Most people go about their daily lives without ever appreciating the importance of lubricant. Where ever there are moving parts greasy and oily coatings are needed to help improve machine efficiency and prolong equipment life. Without a decent lubricant the gears of industry would come to a grinding halt…literally.

This situation has made the search for top quality, long-lasting lubricants a matter of high economic importance.

One of the biggest challenges in sourcing lubricants is finding one that does not foam excessively. Oils that create large numbers of tiny bubbles do not work as effectively, as the bubbles limit viscosity.

But now, researchers from Stanford University in California have made a significant step forward in improving our understanding of how lubricants foam, opening the way for the development of better-quality lubricants that create fewer bubbles.

The breakthrough was made by Vineeth Chandran Suja, a graduate student, led by Gerald Fuller, a professor of chemical engineering, and came via their decision to use a novel technique to analyse the colourful patterns on the surface of individual bubbles in oil.

The technique employed was originally developed to study the liquid layer that lubricates the exterior of the human eye, but by adapting the technology for use in industrial lubricants the team have potentially opened-up a branch of research with a far larger impact on human development.

Previous studies on foaming oils had typically focused on the bubbles formed in the aggregate, but by using the latest visual aid Suja and Fuller were able to zoom in on the iridescent surface of tiny bubbles in oil. In doing so, they saw that the colour of the bubbles was linked to the thickness of the bubble wall. Brighter, more vibrant colours indicate a thicker wall, and therefore a stronger, longer lasting bubble, which in turn leads to a foamier, less-effective oil.

Darker colours were evidence of thinner walls from bubbles that would burst more easily and were found in longer lasting oils which would provide better lubrication.

But most significantly, the researchers were able to see how the persistent bubbles kept such thick walls: The answer, they found, was through evaporation.

As the online scientific journal, Phys.org notes, “[The researchers] observed that evaporation at the top of each bubble caused its surface tension to change, drawing extra oil toward the top. This additional oil made the bubble wall thicker and stronger, and prevented it from bursting. They captured video of the bubbles pulsating as tears of oil pooled at the top, then rolled down the exterior wall of the bubble only to get wicked up to the top again by evaporation. As the cycle continued, these persistent, thick-walled bubbles tended to become undesirable foams.”

You can watch a video of this evaporation process on this YouTube clip.

This was a big surprise for the researchers. As Fuller recalls, “Learning that this whole process is driven by evaporation was a bit of an unexpected result.”

The team have now published their results in the journal, Proceedings of the National Academy of Sciences, where they announce that, “Using a newly developed experimental technique, we show that the stability of lubricant foams can be evaluated at the level of single bubbles. The results obtained with this single-bubble technique indicate that solutocapillary flows are central to lubricant foam stabilization … an unexpected result given the low volatility of nonaqueous liquids.”

Significantly, they also learnt that foaming occurs more easily in blended, multi-grade oils. As Fuller adds, “It turns out, if you want to reduce foaming, you want to use high-purity, single-grade oils.”

Moving forward with this new found understanding of oils foam, the team are now examining ways to further improve their knowledge of how lubricants work. As the Stanford University website notes, the researchers now plan, “… to formalize their understanding of bubble formation, evaporation and foaming with mathematical models that will allow them to simulate how pure or blended oils are likely to perform in real life.”

Once this has been completed, it will enable them (or other research teams) to tackle the hunt for new oils and lubricants that avoid the dynamics of foaming. The team’s second goal is to look for additives that prevent foaming or chemicals that can better disperse foaming once it has occurred.

While there is evidently plenty of work ahead of them, a new method of analysing the bubbles in oils will likely lead to improved lubricant products. Given the importance of keeping the wheels of industry turning, then many lubricant manufacturers and suppliers will welcome this discovery as it lights the way to a longer lasting lube.

‘Knowledge is power’, said the philosopher and essayist Francis Bacon; and he should know, as he was very knowledgeable indeed.

And if this was true in 17^th century England, when Bacon first wrote those words, it is definitely true now. In an age of hacking, industrial espionage, trade secrets, and confidentiality clauses, the chemical industry has become a highly secretive place. Raw material sources are kept secret, prices are ‘upon request’, and chemical formulas are locked in vaults (patent pending).

Yet, with public concern growing over the chemicals used to make everyday products, chemical companies are finding themselves in an increasingly defensive media war.

As the news industry struggles to maintain 24-hour news feeds, Tweets, and minute by minute coverage of events, media outlets are heading towards the ‘shock and horror’ stories that gain clicks and advertising revenue. Chemical leaks, factory explosions, oil spills, and expensive legal cases against chemical producers are all targets for such negative coverage.

Added to this negative façade that the chemical industry wears, are true global concerns of climate change and the circular economy.

Unfortunately, public perception of the chemical industry’s impact on the environment is equally destructive.

As a result, there are signs that the chemical industry has begun to ‘circle the wagons’ and is now acting more as a team. It is beginning to see the benefits of cooperation.

As the World Business Council on Sustainable Development reports, “To deal with the coming challenges, a multi-stakeholder approach is required. Companies in value chains can, for example, combine their data to calculate the ‘avoided greenhouse gas (GHG)’ emissions because of the use of chemicals in their value chain.”

Similarly, in a recent interview, Thomas Arnold, CEO of the chemical manufacturer Biesterfeld, outlined his ideas on the importance of chemical industry cooperation prior to the 2018 Annual Congress of The European Association of Chemical Distributors (FECC). Here he stated that, “it is important to discuss new ideas, strategies and market potentials with our partners and to be open for business expansion and innovative solutions. To mutually benefit from a long-term business partnership, we need to rely on each other and continuously work on boosting our relationship.”

At the same event Karsten Beckmann, a member of the management board at Brenntag, had similar thoughts, stating that, “As in each partnership trust is an integral part – this also applies for chemical distribution. For us it is crucial to listen to the individual needs of customers and suppliers in order to be able to offer them the solution they need. It is all about communication, coordination and flexibility.”

As Jens Cornelissen, general manager of the Merlien Institute, notes, “Rather than guarding innovations behind locked doors, organisations are increasingly understanding and embracing the value behind more open approaches for driving innovation.  Alongside this emerging – and increasingly ‘open’- mindset towards innovation approaches, comes a need to assess how innovation is spearheaded and implemented across the organisation. This entails reviewing, and potentially transforming, innovation frameworks, processes, and expectations to ensure excellent commercial outcomes.”

Meanwhile the global trend of adopting shared databases on chemical safety, such as REACH, is widely seen as being a huge benefit to chemical companies in those regions fortunate to have one.

Even China’s current 5-Year Plan is relocating chemical businesses to chemical parks to ‘enhance innovation and synergies between material flows, logistics, engineering and environmental protection’.

No one, however, can deny the power and profit to be made from the knowledge of individual chemical products. Where would Chemours be without the patented knowledge of Teflon, or DuPont without Nylon? But beyond reaping the benefits of R&D, cooperation can aid chemical companies in the greater challenges of the 21^st century; the circular economy, legislation, public image, trade, & climate change.

So, is knowledge power? Maybe, but increasingly in the chemical industry, shared knowledge leads to greater power.

Like many chemical industry leaders, international experts and innovative thinkers, Jens Cornelissen will be attending CIEX 2018 being held in Frankfurt on September 19^th and 20^th. The event has been created for R&D and innovation experts from the consumer, industrial and specialty chemical sectors, and is a unique platform for participants to learn, exchange ideas, and collaborate.
