In recent years, we have developed several Vapour Recovery Units based on the carbon bed adsorption technology for landbased and offshore crude oil vapour recovery.
New ideas and technology developments are continuously pursued in order to offer solutions for both land terminals as well as tanker application with higher efficiencies, lower investments and easier operation.
Our offshore Vapour Recovery Units have shown excellent robustness in extreme marine weather conditions.
Development at a glance
1994: Kvaerner Process Systems (today Aker Process Systems) started developing a vapour recovery process for shuttle tankers based on single-stage pressurised absorption. This development took place in close co-operation with Statoil and went through the paces of one pilot plant, one prototype and, ultimately, five subsequent units installed on board shuttle tankers to date.
1994 – 1996: Cool Sorption (today Aker Cool Sorption) developed and installed the world´s first major crude oil vapour recovery system for an onshore export terminal – The Sture storage and loading terminal operated by Norsk Hydro at the west coast of Norway. This recovery system is based on a cold liquid absorption process.
2000 – 2005: Aker Cool Sorption modified its standard Carbon Vacuum-regenerated Adsorption technology (gasoline vapour) to handle crude oil vapours. Utilising an existing and operating gasoline plant in Denmark for testing on crude vapours, the concept was proven. The results were extremely good and the first Carbon Vacuum-regenerated Adsorption VOC plant is in operation on the Shuttle Tanker M/T Navion Europa. In addition, a Carbon Vacuum-regenerated Adsorption VOC plant was successfully delivered for Statoil's FSO Åsgard C in the late summer of 2004. Furthermore, a second and third copy of the Åsgard C recovery unit have been purchased by Statoil. These will be installed on Teekay's shuttle tankers DE/T Randgrid and M/T Navion Norvegia, respectively, both operating in the Heidrun field.
