"Spent Bleaching Earth" (SBE) Oil Extraction

The SBE Oil Extraction project was adopted from Professor Dato’ Dr Rosli Mohd Yunus’ patented invention (PI 20030197).

Professor Dato’ Dr Rosli created a process to extract solutes from spent absorbent, or from plant materials, by using organic extraction solvent and ultrasonic energy. The technique used in his invention has proven to improve the extraction process by as much as 95 percent.

Hence, the use of such process in the oil recovery industry would prove more beneficial, in comparison to the conventional one. This process has received both national (ITEX 2003 Kuala Lumpur) and international recognitions (SIIF 2004, Seoul, South Korea).
