| A feasibility of magnetic separation technique was tested for fuel oil recovery from oil/water mixed system. A model system where C type of fuel oil was mixed with water was used in order to make an experimental proof of magnetic separation. Separation was performed by using Sm-Co magnet and fine magnetite particles. After mixing of magnetite particles with oil, oil was absorbed on the particle surface. Subsequently, separation of magnetite particles leads to the recovery of oil from water. About 80 mass% of C type of fuel oil can be separated by the technique using 2 mass% of magnetite particles against fuel oil. This technique was found to be applicable to fuel oil/NaCl solution system as well as fuel oil/water system. Hydrophobically modified magnetite particle was also tested to improve the recovery efficiency. |
