Norsk Spesialolje specializes in the treatment of contaminated water. Some of the treated water comes from waste oil collection, but there is also collected and treated a substantial amount from industry, ships and offshore activities. In respons to an increased demand for treatment of contaminated water, Nosk Spesialolje decided to increase its capacity by building a new and modern process and distribution facility in Grenland. The plant was completed during the autumn of 2014, and has a capacity to treat 35.000 m3 contaminated water per year. The new state of the art facility in Grenland is built to meet future requirements regarding both safety and the environment.
Processing the contaminated water starts with distillation, followed by a chemical/biological treatment. Norsk Spesialolje focuses on “complicated” water which requires treatment beyond standard chemical/biological treatment. Years of experience has proven distillation to be the best treatment method for complicated water. However, the distillation process requires a large amount of energy usage and can therefore be very expensive. The location in Grenland, however, provides Norsk Spesialolje with the ability to use excess heat from the next-door plant (Ineos) as a source of energy for the distillation process. In this way, the energy cost is significantly reduced compared to using electricity or steam from oil. Using this excess heat is also environmentally beneficial, which has resulted in Norsk Spesialolje receiving financial support from Enova (State funding agency) for the construction of the plant in Grenland.
Norsk Spesialolje expects an increased demand for treatment of contaminated water. Because of this, Norsk Spesialolje has reserved extra space at the Grenland plant for the possibility of further increasing its destillation capacity by 35.000 m3 pr year and increasing its tank storage capacity by 13.000 m3.
