| 摘要 |
The invention relates to a device of producing low-sulfur high-octane-number gasoline with low cost and method thereof, the device is composed of an extractor, a first cutting column, an etherification device, a hydrogenation desulfurizer, a reforming pretreatment device, a second cutting column, an isomerization device, a reformer and a stabilizing device. Sulfur in raw material is enriched in extracted oil by introducing extractor in the invention, thereby reducing the scale of hydrogenation desulfurization device. The scale of reformer is increased by delivering heavy raffinate obtained from the first cutting column in the reformer. Benzene extractor and corresponding fractionation device are saved by adjusting the cutting temperature in the second cutting column, thereby greatly lowering investment and energy consumption, and increasing the gasoline yield. The investment of reformer is reduced, while the liquid yield is increased by introducing the reforming patent technology. The sulfur content in gasoline products is lowered to 10 ppm by selecting the device and method. The device and method have obvious advantages in investment, hydrogenation scale, product cleanliness, quality, etc. |
