Environmental impact and economics of propane and propene production

What is it about?

Propane and propene are important chemicals. They are usually produced via petroleum refining. However, there is a better way to produce these chemicals. It is known as carbon capture utilization (CCU). CCU can convert extra carbon dioxide from air into useful chemicals. This includes propane and propene. Recent studies have shown that CCU is a greener choice for producing propane and propene, as compared to traditional methods. In this study, researchers created a computer model to explore the environmental and economic impact of using CCU. They then compared it to the impact of using fossil fuels. The steps used for making propene and propane were modelled by the computer model. It also pointed out the factors that were important for practically using CCU.

Why is it important?

There is a growing focus on greener methods for producing fuels that can reduce carbon emissions. Such methods can also tackle climate change. This study found that compared to traditional methods, use of CCU greatly lowers the environmental impact. Moreover, the use of grid electricity during propane production majorly contributes to its environmental impact. This impact was highest and most important in terms of marine toxicity. The study also found that propene production has a lower environmental impact. The results showed that the impact was less than half that of propane. This difference was due to the specific balance of hydrogen and carbon monoxide needed for propene production. This, in turn, also resulted in reduced water usage. KEY TAKEAWAY: The study identifies key factors that determine the performance of propane and propene production methods. However, using CCU to produce propane and propene is a better and greener choice compared to other production methods. This research relates to the following Sustainable Development Goals: • SDG 7: Affordable and Clean Energy • SDG 9: Industry, Innovation, and Infrastructure • SDG 12: Responsible Consumption and Production • SDG 13: Climate Action
