Happy May Day 2024! Safety first. Let’s give praise and support to the achievements in China’s chemical engineering technology and equipment. **********************【Ten Years of Great Development in Chemical Engineering Equipment】A continuously updated summary post is available; feel free to join the discussions at https://bbs.hcbbs.com/thread-3576046-1-1.html (Source: Haichuan Chemical Engineering Forum) ***************** After completing the industrial experiments on the tubular liquid-phase hydrogenation process for reformed oil, construction of Changling’s aviation fuel tubular liquid-phase hydrogenation unit began on November 19, 2013. The plant has a production capacity of 600,000 tons per year, and the project is scheduled to be completed and put into operation in the first half of 2014. 　　In 2011, Changlian began researching new tubular liquid-phase hydrogenation technologies, completing laboratory scale tests, industrial pilot tests, as well as more than a year of industrial-scale tests on tubular liquid-phase hydrogenation of reformate oil. Operational data show that this technology features simple operation, stable performance, and consistent product quality; it also offers significant energy savings and cost reductions, making it highly valuable for widespread adoption. No prior reports of similar technologies exist domestically or internationally, and Changlian has applied for a patent for this technology. 　　To overcome the technical challenges associated with the tubular liquid-phase hydrogenation process, Changling Refinery modified the reactor used in its hydrogenation facilities for the first time to a tubular reactor in order to carry out liquid-phase hydrogenation for desulfurization and olefin removal. This approach enabled complete purification of both the production process and the product quality, resulting in significant economic and social benefits. It is understood that the overall production process for this device is simple, with a total investment of less than 10 million yuan, which significantly reduces the construction costs and production expenses associated with similar devices.
