Shell is planning a major investment to replace the furnaces at its Moerdijk ethylene steam cracker in the Netherlands.
Eight new furnaces will be installed to replace 16 older units. The capacity of the facility will not change, but the site's energy consumption and greenhouse gas (GHG) emissions will be significantly reduced, including a 10pc cut in CO2 emissions, Shell said.
The replacement of the first furnaces will begin in the spring of 2022. Shell aims to complete the work in 2025. The new furnaces will be shipped to the site in modules, enabling the cracker to continue to operate throughout the upgrade project.
Moerdijk's ethylene capacity of 970,000 t/yr makes it the second-largest in Europe. It also has nameplate propylene capacity of 500,000 t/yr. It is not clear if the feedstock flexibility of the plant will change with the new furnaces. Moerdijk's existing set-up allows for significant flexibility between naphtha, LPGs — mainly butane but some propane — and gasoil.
"This investment at Moerdijk contributes to the reduction of carbon emissions from our manufacture of chemicals and to Shell's ambition of becoming a net-zero emissions energy business by 2050 or sooner," Shell's executive vice-president of chemicals Thomas Casparie said.
European crackers face the prospect of tighter regulations in the future surrounding GHG emissions and decarbonisation. Technology and regulations have evolved to tackle issues that were not as high a priority when the majority of European crackers were built. The last new cracker to be built in Europe was over 20 years ago, although Ineos is progressing with plans to build a new cracker in Antwerp.
