The plant consists of four parts: a production building, a distillation tower, a service building and a tank enclosure. The four parts are linked by a common structure which contains a pipe bridge and safety walkways. The production-related buildings are equipped with surfaces of cement and steel plate in various shades of grey, while the service building is in a warm yellow-orange colour. The facade on the motorway side is equipped with large glass panels which provide a view of the technical equipment, including the distillation tower, which is the tallest building at the plant.
