摘要
A method for desulfurization and aromatic compounds removal of a fuel oil being recovered from waste lubricating oil with the use of ozone as an extracting agent, including a fuel oil extraction process for mixing fuel oil with ozone and performing the extraction process of desulfurization and aromatics removal, a high speed centrifuge separation process using a high speed disc separator to separate sulfide and aromatics from the produced fluid mixture so as to obtain a mixture of fuel oil and extracts, a fuel oil recovery process for performing a core operation of short path distillation to recovery fuel oil, an ionic liquid recovery process for performing a core operation of short path distillation to recover ionic liquid and a utility facility process using a cooling tower and a chiller to generate and circulate a chilled water for circulating through the fuel oil recovery process short path evaporator and the ionic liquid recovery process short path evaporator and related external cold wells for condensing the recovered fuel oil and ionic liquid.
