Upgrading units for National V and National VI gasoline and diesel in petrochemical enterprises and paths for technical transformation
Thread Content
In the process of upgrading domestic vehicle gasoline and diesel from National Standard 4 to National Standard 5, and then from National Standard 5 to National Standard 6, from the perspective of oil refining companies, what adjustments are necessary to meet the new technical standards? Is it required to build new facilities, or is it sufficient to optimize the ratios of various types of gasoline and diesel, and if so, how should those ratios be adjusted? Please, experts, share your opinions.
Optimizing the blending of gasoline and diesel is only temporary; as national standards become more stringent, reforming gasoline and hydrogenating diesel have become essential for the survival of large refineries.
