A device for the low-cost production of low-sulphur, high-octane gasoline, comprising an extraction device (1), a first splitting tower (2), an etherification device (3), a hydrodesulphurization device (4), a reforming preprocessing device (5), a second splitting tower (6), an isomerization device (7), a reforming device (8), and a stabilizing device (9). The extraction device (1) concentrates the sulphur from the feedstock into the extract, allowing for the use of a smaller hydrodesulphurization device (4); the heavy raffinate extracted by the first splitting tower (2) is sent to the reforming device (8), allowing for the use of a larger reforming device (8); the splitting temperature of the second splitting tower (6) is adjusted such that savings can be made on benzene extraction and the corresponding fractional distillation device, thereby greatly reducing cost and energy consumption while increasing gasoline yield. A method for the low-cost production of low-sulphur, high-octane gasoline is also provided. The device and method reduce the sulphur content of the resulting gasoline product to 10 ppm and reduce the related costs and expenses. |
