Nynas cuts CO2 emissions with 12% The Nynas refinery in Nynäshamn, Sweden, is decreasing its carbon dioxide (CO2) emissions by 20 000 tonnes or 12 % annually. This is possible due to replacing naphtha with natural gas for the hydrogen production. Recently, AGA inaugurated the first plant for liquefied natural gas (LNG) in Sweden, located next to the Nynas refinery in Nynäshamn. As a result, Nynas can now use natural gas for the production of hydrogen and thus dramatically reduce the refinery's carbon dioxide emissions. "With natural gas we can better meet the stricter environmental demands. Natural gas contains no sulphur or heavy metals and has significantly lower nitrogen oxide and particle emissions. For Nynas the transition to natural gas is a great example of how we contribute to an improved environment and at the same time lower our costs," says CEO Staffan Lennström. The demand for oil that is tailored to suit increasingly stringent health and environmental requirements is growing across the world. By way of example, the Nynäshamn refinery exports environmentally sound tyre oil to tyre manufacturers all over the world. The supply of hydrogen is key to Nynas’ specialised manufacturing process. Hydrogen is used to improve the chemical composition of the oil and to remove impurities.
