A device and system method for resource utilization of residual oil

Abstract

The application provides a residual oil resource utilization device and system method, and belongs to the field of residual oil resource utilization.The residual oil resource utilization device adopts a precision filtration device to replace a traditional porous medium adsorption mode with high energy consumption and low separation efficiency, realizes efficient separation of residual oil and oil products in residual oil, avoids consumption of materials, and improves separation precision and efficiency.A dry residue extraction device is used, and further separation of dry residue and residual oil can be realized by using a small amount of extractant.The dry residue obtained by separation is calcined by a precision incineration unit to obtain metal ash, and then nickel, molybdenum and vanadium are recovered by wet metallurgy.The residual oil and the extractant obtained by separation are treated by a delayed coking unit to obtain petroleum coke and distillate oil, so that full recovery and utilization of slurry bed residual oil is realized, the treatment process is high in efficiency and low in cost, and is suitable for large-scale industrial application.
