Neste Oil has developed a NExBTL renewable diesel production technology. NExBTL renewable diesel is produced by hydrotreating vegetable or waste oils. Based on the production process it is classified as hydrotreated vegetable oil (HVO). It is a drop-in substitute of diesel which means that it is hydrocarbon oil with chemical composition comparable to fossil fuel. Started in 1948 as a state petroleum company, Neste Oil’S headquarter is in Espoo, Finland.
Neste Oil Feedstocks
Neste Oil’s NExBTL renewable diesel production technology is feedstock flexible. It allows the use of any vegetable or waste oil. At present palm oil, stearin, palm oil fatty acid distillate, rapeseed oil, camelina oil, jatropha oil, soybean oil and the waste animal fat produced by the food processing industry are being used as feedstock.
In Finland approximately 1,0000 tons of tall oil pitch residue is produced annually by tall oil refiners. Neste Oil has utilized this feedstock for refining into traffic fuel.
The company has also made an agreement with algae biomass developer Cellana in 2013 to purchase Cellana’s algae oil for use as a feedstock in the future for producing renewable fuel.
As per the information in the Neste Oil’s website, the company also plans to utilize other feedstocks such as algae oil, microbial oil and wax derived from wood-based biomass for producing NExBTL renewable diesel. The process for utilization of these feedstocks is in various stages of development.
At present NExBTL diesel and NExBTL aviation fuel are under production. Both the products are based on Neste Oil’s proprietary NExBTL technology. Based on the same technology three chemicals NExBTL naphtha, NExBTL propane, and NExTBTL isoalkane are also being produced.
Renewable diesel plants
Neste Oil’s NExBTL plants are capable of producing both NExBTL renewable diesel and NExBTL renewable aviation fuel.
In 2011 the company started plant with 800,000 t/a capacity in Rotterdam, Neatherlands. Another NExBTL renewable diesel plant is operational in Singapore since 2010. Neste oil also owns two petroleum refineries in Porvoo and Naantali in Finland. Porvoo plant produces renewable diesel as well and came on stream in 2007.
