The overall objective of the project is the "smart" exploitation of Petroleum Refinery Sludges (PRS), produced by the Refiner ... y of MOTOR OIL (HELLAS) - CORINTH REFINERIES S.A., the largest private industrial complex in the country with a processing capacity of 185000 barrels of crude oil per stream day (BSD). PRS are wastes originating from crude oil processing into fuel and relative nonfuel products. After sludge pretreatment by dewatering and/or deoiling (for reduction of volume and residual hydrocarbon content), due to their hydrocarbons and heavy metals content, these sludges are classified as hazardous waste and their treatment is a pre-requisition before their final disposal. The main idea of the LIFE DIANA proposal is the use of these wastes for the development of a Valorised Sludge Mixture (VSM) through their proper integration with cost efficient industrial minerals available in Greece and other countries, like perlite and bentonie, aiming to the PRS transformation into higher value commercial products. read more
