Waste Oil Extraction

• 

The present research and development (R&D) project on Waste Oil Extraction is focused on developing a “Base Oil Recovery Plant from Spent Lubricant Oil using Solvent Extraction Technology”.

The objectives of this project are to develop a pre-commercialization base oil recovery plant – with an annual production capacity of 7,000 metric tonnes – and to patent and market the Solvent Extraction Technology.

This project was assumed from the lab-scale invention patented by Professor Dato’ Dr Rosli Mohd Yunus, which was fully financed by the Ministry of Science, Technology & Innovation under the Technofund Grant.

The Solvent Extraction Technology developed under this project is believed to be superior to the one currently in practice, in terms of product yield and quality. This new technology uses the composite solvent extraction to boost the recovery of base oil while simultaneously expelling impurities in the sludge as by-products. The novel features of this technology include an integrated process of extraction, accelerated flocculation, centrifuged filtration, solvent recovery and short-path distillation for base oil recovery.
