Petroleum ether is widely used as a solvent in the extraction of aromatic hydrocarbons; however, due to environmental concerns, particularly the implementation of Announcement No. 11, its use has been restricted. In light of this situation, several alternatives can be considered: 1. Find substitutes: It is advisable to look for environmentally friendly alternatives, such as water-soluble solvents or green solvents, to replace the use of petroleum ether. This way, environmental policies can be adhered to while maintaining the efficiency and cost-effectiveness of the production process. 2. Process improvement: By improving processes and optimizing equipment configuration, the usage amount of petroleum ether can be reduced, or the dependence on petroleum ether can be minimized. 3. Technological upgrades: Consider introducing more advanced technologies and equipment, and utilizing more efficient processes to replace the traditional naphtha extraction process, thereby reducing the demand for petroleum ether. 4. Adjust the product structure: Adjust the product structure according to market demands, introduce new products or develop new application areas, so as to reduce dependence on petroleum ether. In summary, in the face of restrictions on the use of petroleum ether, various approaches can be considered—such as finding substitutes, improving processes, upgrading technologies, and adjusting the product structure—to address the problems arising from these restrictions. This requires enterprises to comprehensively consider and make trade-offs in various aspects such as market demand, environmental policies, and technological levels, while taking appropriate measures to address the challenges. .
