Gulei Chemical’s world’s largest phthalic anhydride plant oxidation reactor
Thread Content
On September 23, 2020, the oxidation reactor for anhydride production – the equipment with the highest single-line capacity in the world for such facilities – arrived successfully at the Gulei port. A total of 48 pieces of equipment were delivered, including two oxidation reactors for anhydride production along with related accessories, with a total weight of around 964 tons; the largest of these reactor units weighed over 330 tons.
The project is designed to produce 260,000 tons of phthalic anhydride and 7,000 tons of maleic anhydride per year. Ruijie Chemical Company utilizes the PX project of Fuhai Chuang Company as a foundation, and introduces world-class production equipment. Using o-xylene as the main raw material, through processes such as air-mixed oxidation, gas cooling, pre-cooler treatment, switching condensation, and distillation, the main product produced is phthalic anhydride. This approach enables optimization of production costs; the company’s overall energy consumption and market competitiveness rank among the highest in China’s phthalic anhydride industry, giving it strong competitive advantages in this sector.
