Oil Refineries: Air Pollution's Worst Enemy?

Oil refineries are a major source of air pollution, emitting hazardous and toxic pollutants that pose a significant threat to human health and the environment. These pollutants include cancer-causing benzene, particulate matter, nitrogen oxides, carbon monoxide, and sulfur dioxide. The impact of refinery pollution is not limited to the immediate vicinity of the refineries but can also affect communities located downstream and those consuming the refined products. Incidents of air pollution from refineries are not rare, and the health risks associated with exposure to refinery pollutants are well-documented. With the petroleum refining industry facing increased scrutiny over its environmental impact, investors and companies are recognising the importance of implementing effective measures to reduce air pollution and comply with regulations.

Oil refineries emit hazardous and toxic air pollutants

The problem is not isolated to a single location, as refineries are a crucial part of the energy infrastructure in many countries, including the United States. The refining sector has the highest pollution levels in the oil industry, and the various pollutants emitted during the refining process have detrimental effects on the environment and human health. This has led to increased scrutiny and the likelihood of stricter monitoring and regulation in the future.

Several incidents have highlighted the severity of the issue. For example, in 2016, Tesoro settled alleged Clean Air Act pollution violations at six refineries, including its Anacortes facility, for $425 million. The settlement primarily funded the installation and operation of pollution control equipment, with a smaller portion allocated to improving public health in the surrounding communities. Similarly, in 2015, the Shell Refinery at Anacortes was fined for a violation of shutdown and decontamination procedures, which resulted in the release of chemicals, including benzene, affecting the Swinomish people, who reported symptoms such as irritation, headaches, and nausea.

The financial implications of managing air pollution can be significant for companies, and investors are becoming increasingly aware of the importance of supporting companies with strong environmental practices. Sustainalytics' ESG Risk Ratings framework assists investors in evaluating petroleum refiners' ability to manage air pollutants and assessing their programs to reduce emissions. However, currently, only a small percentage of refiners have robust programs in place to address non-greenhouse gas emissions.

Overall, the emission of hazardous and toxic air pollutants from oil refineries is a critical issue that requires attention and action. The health and environmental risks associated with these emissions are severe, and the impact on nearby communities cannot be overlooked. To protect human health and the environment, it is crucial to establish and enforce environmental protocols to control air pollution in the petroleum refining industry.

Health impacts on communities living near refineries

Living in close proximity to oil refineries can have a range of adverse health effects on communities. Several studies have reported significant disparities in health outcomes between communities living near oil refineries and those that don't. For example, a study in Jordan found that residents of Al-Hashimeya, a town near an oil refinery, were at a higher risk of having phlegm and were more likely to suffer from skin problems and asthma compared to residents of Bal’ma. Similarly, the California government has identified several negative health consequences associated with living near a refinery, including an increased risk of asthma, cancers, birth defects, neurological damage, cardiovascular damage, respiratory issues, and blood disorders.

The toxic emissions from refineries can lead to a perception of poor health among residents, with a constant threat of potential explosions or leaks that could have rapid and lethal consequences. The chronic stress associated with living near a refinery can also cause mental health issues. Furthermore, minority groups are disproportionately affected by the toxic harm of refineries due to poor city planning and wealth gaps. These communities often have limited access to healthcare and treatment, exacerbating the impact of refinery pollution on their health.

The specific contaminants and pollutants from oil refineries that contribute to negative health outcomes require further study. However, it is clear that the presence of an oil refinery can negatively impact the health and well-being of nearby communities. This is supported by observations that residents living closer to refineries are statistically more at risk of developing health disorders, even if they are several miles away. As a result, governments are encouraged to adopt strict policies regarding the construction of oil refineries near residential areas and to prioritize remote and uninhabited locations for such industries.

To mitigate the health risks associated with living near refineries, community members are advised to take proactive measures. This includes advocating for air monitoring systems, participating in local politics, conducting health surveys, and taking personal protective actions such as taping windows, wearing masks during high pollution levels, and investing in air filters. These steps can help reduce the potential harm caused by refinery pollutants and empower communities to take control of their health and well-being.

Petroleum refining is the most polluting sector of the oil industry

The oil industry is one of the most regulated sectors worldwide, with strict laws governing atmospheric emissions. However, petroleum refining is the most polluting sector within this industry. This is due to the wide range of toxic chemicals generated by refineries, which can dramatically worsen the air quality, posing risks to human health and the environment.

Refineries employ chemical processes to transform crude oil into valuable products with a wide range of industrial uses. These processes are a significant contributor to air pollution, both locally and at a distance. The most apparent air pollution issues in the petroleum industry are associated with the refining processes.

Various pollutants are released during the different phases of petroleum refining. These pollutants contribute to poor air quality, which can have detrimental effects on human health and the natural environment, including flora and fauna. As a result, establishing and enforcing environmental protocols in the petroleum refining industry is crucial to mitigating these impacts.

To minimize the environmental impact of petroleum refining, it is essential to develop innovative refining processes. This includes investing in advanced technologies for precise air quality monitoring and implementing rapid response systems for leaks and anomalous emissions. By improving air quality and reducing environmental impact, these measures contribute to a more sustainable future for the energy production sector.

Environmental protocols are crucial to control air pollution

Environmental protocols are crucial to controlling air pollution, especially in the oil refining industry, where pollution is at its highest. The various phases of the petroleum refining process discharge different pollutants, and the industry is the largest industrial source of methane, a potent greenhouse gas, as well as volatile organic compounds that contribute to smog formation.

The imposition of environmental protocols is essential to mitigate the impact of these emissions on the environment and human health. Protocols should aim to reduce emissions and improve air quality, especially in developing countries facing increased energy demands, industrialization, and overpopulation, which further exacerbate air pollution.

One example of an environmental protocol is the US EPA's Clean Air Act regulations for the onshore oil and natural gas industry. These regulations target equipment and activities within the industry to reduce methane and other harmful air pollutants, helping to combat climate change and protect public health.

Additionally, the unique composition of petroleum and its extensive range of finished products make it a pivotal natural resource for many businesses and the world's economic development through energy usage. Therefore, environmental protocols must also consider the economic implications of any measures to control air pollution from the oil refining industry.

Overall, the establishment and enforcement of environmental protocols are vital to curbing air pollution, protecting the environment and safeguarding human health, while also taking into account the economic significance of the petroleum industry.

Companies need to invest in plans to reduce emissions

Oil refineries are a major source of pollution, and companies need to invest in plans to reduce emissions to protect the environment and public health. While crude oil refining techniques are always improving, the growing global demand for petroleum products makes complying with environmental legislation challenging.

To achieve a significant reduction in emissions, companies need to invest in a variety of measures. Firstly, they can tackle methane emissions, which is the single most important measure to reduce overall emissions from oil and gas operations. Eliminating all non-emergency flaring and electrifying upstream facilities with low-emissions electricity are also crucial steps. In addition, equipping oil and gas processes with carbon capture, utilisation, and storage (CCUS) technologies can significantly reduce emissions. Expanding the use of hydrogen from low-emissions electrolysis in refineries is another effective strategy. These measures are cost-effective and can even lead to additional income streams by reducing the waste of gas.

Furthermore, companies can convert smaller refineries to produce sustainable aviation fuel (SAF) or biorefineries, reusing existing infrastructure such as tankage, towers, and pipelines. Strategic unit shutdowns and the substitution of green hydrogen can also help reduce emissions. Accurate emissions monitoring is also essential for companies to comply with environmental regulations, avoid penalties, and reduce legal risks. Continuous monitoring helps detect leaks early, optimises processes, and protects worker health and surrounding communities.

To build public trust, companies must also commit to transparency in monitoring, reporting, and verifying emissions from their activities. This includes improving the accuracy, availability, and transparency of emissions data. By investing in these plans and technologies, oil companies can significantly reduce their emissions, contributing to global decarbonisation efforts and preserving health and ecosystems.
