Oil treatment plant
Lindum OBA
Liquid masses from sand traps, wash halls and oil separators contain a number of different types of pollution, and have traditionally been sent to landfill. Lindum AS wanted to do something about this, and Nordisk Vannteknikk was therefore commissioned to design, project and build a facility for receiving these masses. The purpose of the facility was to minimize the amount of waste sent to landfill by recycling and reusing as many resources as possible. We are therefore incredibly proud that this facility is operational today and thus contributes to sustainable resource recovery.
What is OBA?
Lindum OBA is more than just a reception facility for liquid masses – it is a platform for cutting-edge technology. OBA is an abbreviation for oil treatment plant, but the plant consists of three core components in total: Oil treatment unit, sand separation and an advanced purification plant.
In oil processing, water and sludge are received from sources such as oil separators and wash halls. Drum filtration ensures that sand and gravel are separated out, and separation tanks are utilized to separate oil from water, before the recovered oil is further refined for optimal concentration.
The sand collection section consists of separate reception areas for masses without large amounts of oil, as well as sand and water from the oil reception area. The sand collection also uses drum filtration and separate sand washers to separate clean sand from liquid masses, while the treatment plant completes the circle by delivering purification technologies such as polyclay treatment, lamella separation and sand and coal filtration.
Recycling and Sustainability
Lindum OBA goes beyond just water purification. The plant demonstrates the possibilities of sustainable resource management. The purified water is collected and reused in the plant as flushing water at the receptions, drum filters and other essential locations. Even the overflow water is efficiently diverted for further use, an innovative strategy that contributes to the optimal utilization of water resources. At the same time, it is possible to clean and sell the extracted sand for further use, which makes the process both more sustainable and economically beneficial. The sludge can also be reused, including in pyrolysis processes.
