Refining separates the "black gold" that is crude oil into its constituent parts and prepares these for further use. The technology usesd by fefineries must itself be "processed" at regular intervals. When it comes to a shutdown for maintenance of this type, cleaning agents, greases, bonded coatings and assembly pastes have a role to play at practically every turn, as the example of the current overhaul at the OMV refinery in Schwechat, Austria shows.
