Abstract

The invention relates to a method for deacidifying a lubricating oil mixture. According to the invention, the lubricating oil mixture that contains acid is conducted at a temperature of less than 60 °C into a neutralization reactor, the lubricating oil mixture is brought into contact with calcium carbonate and the acid in the lubricating oil mixture is allowed to react with calcium carbonate, so that the reaction produces calcium compounds, carbon dioxide and water. In addition, the invention relates to a corresponding apparatus and use.
