Japan Organization for Metals and Energy Security (JOGMEC)together with Cosmo Energy Group company Cosmo Oil Co., Ltd. and Abu Dhabi Oil Co., Ltd. have succeeded in developing a sludge volume reduction ("SVR") technology that recovers useful oil from sludge accumulated in crude oil storage tanks, enabling a 50% or more SVR compared to conventional technology.

Sludge is the mixture of oil, water, and solid material (sand, rust, etc.) contained in crude oil that has settled and accumulated at the bottom of crude oil storage tanks. Traditionally, sludge is discharged from tanks during overhaul inspections and disposed of as industrial waste.

JOGMEC, Cosmo Oil, and Abu Dhabi Oil have been working since 2016 to develop a technology to reduce sludge volume, with their efforts culminating in the development of an SVR technology that combines technology to separate sludge into useful oil and unnecessary water and solid material using a centrifugal separator with technology that coverts the recovered oil back into crude oil by mixing it with newly produced crude oil. Cosmo Oil licensed its SVR technology to Cosmo Engineering Co. Ltd. for sludge accumulated in crude oil storage tanks owned by Abu Dhabi Oil. As a result of verification testing for all accumulated sludge, the parties succeeded in reducing sludge volume by more than 50% compared to conventional technology.

How Conventional Technology and SVR Technology Works

  • Sludge

  • Centrifugal Separators

With the successful development of this latest SVR technology, it is now possible to drastically reduce the volume of sludge, which has until now been disposed of as industrial waste. The three parties are committed to further improving the technology based on expertise gained through verification testing and promoting its commercial deployment not only in oil-producing countries but also at oil terminals in and outside Japan.
