Finland: Renewable Polyolefins Borealis Invests 29 Million Dollars for New Naphtha Storage Cavern

Editor: Ahlam Rais

The new naphtha cavern has recently been commissioned in Porvoo, Finland. With this project, Borealis will now be able to source and store naphtha from the global market in a cost-efficient manner. The cavern is also expected to store renewable naphtha which proves useful for the production of renewable polyolefins.

Finland – Borealis recently announced that its new naphtha cavern in Porvoo, Finland has now been safely commissioned as of October 2020. Having invested around 29 million dollars in the construction of this 80,000 cubic m facility, Borealis can now source and store naphtha for its Porvoo operations from the global market in a more flexible, cost-efficient, and secure way. The cavern can also accommodate renewable naphtha, making it possible for Borealis customers in the future to draw on certified renewable polypropylene (PP) and polyethylene (PE), as well as renewable base chemicals, ethylene, propylene and phenol.

Construction of the new cavern began in 2019 and was completed safely, sooner than projected, and significantly under budget. Located 90 meters below ground, the storage volume of the new cavern enables Borealis to source feedstock from various sources and markets. Naphtha can now be delivered by large marine vessels (up to 35 kilo tonnes) in addition to rail. The new Porvoo cavern has also been built to accommodate the storage of renewable naphtha, thus enabling Borealis to produce renewable base chemicals and renewable PP and PE, certified by the International Sustainability and Carbon Certification (ISCC Plus certification) scheme.

Current Challenges for Polyethylene Market and Projects

Polyethylene is one of the most widely used plastic resins in the world, accounting for over 1/3rd of the global plastics market.

While the market has been growing in the past, it is now experiencing a reduction in price that can be traced back to several factors including trade disputes, bans on single use plastics as well as overproduction. These factors are further exacerbated by the recent outbreak of COVID-19, which has an effect on the global economy.

This 11-page Expert Insight further explores reasons for the decline as well as possible strategies to mitigate these problems.

“A core component of our sustainability strategy is to contribute to societal progress and to enable more sustainable living while at the same time delivering robust financial results for Borealis and our stakeholders,” says Martijn van Koten, Borealis Executive Vice President Base Chemicals and Operations. “The innovative cavern in Porvoo improves our commercial flexibility and will make a valuable contribution to the achievement of our sustainability goals and the circularity of our products.”

“Borealis sees investment in our European assets such as Porvoo as a clear sign of our commitment to enhancing the safety, profitability, and sustainability of our operations,” says Thomas Van De Velde, Borealis Senior Vice President Hydrocarbons & Energy. “Our new cavern makes Borealis more independent and flexible in our sourcing of naphtha while enabling the production of renewable feedstock.”

Naphtha is used in the petrochemical industry to produce olefins in steam crackers. Borealis sources feedstock such as naphtha, butane, propane and ethane from the oil and gas industry, as well as renewable feedstock from the market, and converts these into ethylene and propylene through its olefin units. Its flexible steam cracker in Porvoo produces both ethylene and propylene.
