The industry park of Takalaanila in Oulu has been in industrial use since the 1950s. The most significant processing industry operators in the park are Eastman Chemical Company / Taminco Finland Oy’s formic acid plant, Kemira Oyj’s hydrogen peroxide plant and Air Liquide Finland Oy’s air gas plant. These production facilities were previously owned by Kemira and are still closely integrated with each other.
Also located in the Takalaanila industry park are Oulun Energia Oy’s eco power plant plus heating centre and Laanilan Voima Oy’s power plant, which produce electricity, steam and district heating for the needs of local industry and the City of Oulu. Oulun Energia’s new CHP power plant is also under construction in the park.
Information about the Laanila district
Eastman Chemical Company / TAMINCO FINLAND, formic acid production
Formic acid production capacity is approx. 100,000 t/a.
The formic acid is refined also further into other products, such as potassium formate and fodder preservatives (AIV fodder).
The formic acid production process is based on gasification of heavy fuel oil. The most important chemicals used by Eastman include methanol and the ammonia and potassium hydroxide used in formate production.
Kemira, hydrogen peroxide production capacity
- Hydrogen peroxide production capacity is 65 000 t/a
The hydrogen required for hydrogen peroxide production is obtained from synthesis gas originating from Eastman Chemical Company’s formic acid plant. The synthesis gas is produced from fuel oil for formic acid production.
Sulphur from the synthesis gas is salvaged for producing sulphuric acid.
In addition, Kemira’s plant's peracetic acid capacity is 10,000 t/a.
Air Liquide Finland, air gas production
The air gas plant produces oxygen and nitrogen in liquid and gas forms as well as liquid argon.
Oxygen produced in the plant is used in the production of synthesis gas from heavy fuel oil for Eastman and Kemira plant production purposes.
The electrical output of the power plant is 19 MW and thermal input 135 MW.
The Laanila Voima power plant uses mainly peat and timber to produce electricity and heat for Laanila district plants as well as Oulun Energia power company. Other fuels include coal, oil and processing gases from the district’s industry.
Oulun Energia, ECO POWER PLANT
The plant’s heat input is 53 MW.
The Oulun Energia eco power plant is fuelled by waste sorted at source. Some of the steam produced by the plant is directed to the turbines of the Laanilan Voima power plant.
Oulun Energia Oy also has a 49-MW thermal power plant burning light fuel oil and a bedrock storage for district heating.
An integrate such as the Takalaanila industry park offers a lot of opportunities for collaboration and possibilities to organise and, if necessary, outsource operations cost-efficiently compared to a facility that has no other processing industry in its immediate vicinity.
Transport and traffic
The park is located next to excellent traffic connections at the intersection of Highway 4 (E75) and Route 20 (the road to Kuusamo). Since the Laanila area has widescale chemical and energy production, the park has existing, good connections for heavy traffic. The distance from Oulu city centre (railway station) is approx. 4 km, the port is 10 km away, and the distance to the airport is only 18 km. There is also a railway connection to the park – part of it is being used by Eastman Chemical and the disused section can be reintroduced to use, for example for material deliveries.
Acquisition and use of raw materials
The biorefinery will use raw materials suited also for the power plant designed for energy production, which brings significant benefits. Acquisition and use of raw materials can be coordinated so that the biorefinery uses the most suitable batches from the raw material flow, and materials less suited for biorefinery use are directed to the power plant.
Plenty of electricity and steam production is operational in or planned for the industry park. The capacity of Oulun Energia Oy’s upcoming power plant is enough to ensure sufficient energy supply for the biorefinery. The construction of the power plant will be complete in late 2020.
Processing, cooling and extinguishing water
The cooling water needed for the biorefinery can probably be retrieved from the Oulu River and discharged back into the river after use. The biorefinery will likely obtain most of the processing water that it requires by recycling water flow created in the process. The need for make-up processing water can probably be covered with the processing water manufacturing equipment of current industry and/or the new power plant. The supply of necessary extinguishing water can likely be integrated with the extinguishing water system of other operators in the park.
Current production in the park does not require biological wastewater processing. Wastewaters have been processed locally and discharged into the Oulu River. There are underwater safety pools in the park in case of possible leakages or extinguishing water use. There are collection pools and sewerage for rainwater, and these can be closed in case of chemical leakage, for instance. Sewers leading to the waterways are equipped with oil separation.
The biorefinery can utilise chemicals already produced in the Laanila park. If the biorefinery uses the organosolv process based on formic acid, the Eastman formic acid production capacity is enough to cover the biorefinery’s entire formic acid need, which amounts to a few tons in a year. The sulphuric acid produced in the park is particularly suitable for adjusting the pH in the biorefinery. The biorefinery may also need nitrogen as a protective gas, and it is produced by Air Liquide within the same park.

In the Oulu zoning plan for 2020, the area has been marked out as an industrial area, more specifically an industry and storage area where a significant plant for manufacturing or storing dangerous chemicals may be situated. The north part of the area has been zoned as an industrial area where the environment sets special requirements for the type of operation. The industrial area is surrounded by an area zoned as recreational. Also workplace areas are located in the southeast and the northwest. The nearest residences are located approx. 500 m from the production facilities.
Possibilities to situate a biorefinery in Kemira Oyj area
The biorefinery and related energy production are operations defined in the regional land use plan. The existing city plan allows situating a biorefinery in the area without a plan change. Kemira Oyj has reacted positively to the plans to situate a biorefinery in the industry park. When situating a biorefinery in the park, the environmental impact assessment must be limited to the area of the refinery itself.
A survey concerning synergy benefits of the biorefinery includes locating options for the biorefinery as well as a raw material yard and a debarking plant within the property owned by Kemira Oyj. The optional locations are based on the size of the available space, the proximity of the planned thermal energy plant, and the possibility to find available storage facilities near the refinery.
