Title:
METHOD AND SYSTEM FOR RECOVERING METALS FROM HEAVY OIL
Document Type and Number:
WIPO Patent Application WO/2023/130454
Kind Code:
A1
Abstract:
The present invention discloses a method and system for recovering metals from heavy oil. The method comprises: stirring and mixing a heavy component oil and a solvent oil to obtain a mixed oil; separating the mixed oil into a solvent-enriched insoluble substance and a light oil component; heating the solvent-enriched insoluble substance, wherein the dry distillation temperature is lower than the sublimation temperature of metals and metal compounds thereof; and crushing and sorting solid carbon components obtained from the dry distillation to obtain various solid particle components that are uniform and consistent in granularity and rich in different metals. By means of the process route consisting of mixing with the solvent oil, separation in a sedimentation or centrifugation mode, oxygen-isolated dry distillation at a relatively low temperature, and smashing and sorting, the method is in accordance with the industrial direction of developing clean and low-carbon fuels, and the energy consumption and pollution are relatively low; and compared with a traditional combustion mode, the process route of the system is low in terms of the recovery cost and more environmentally friendly, and also does not drastically change the form of existence of the heavy metals or even generate some alloys, thereby greatly reducing the complexity of subsequent treatments.
