Are there any catalytic cracking units under construction now? What type are they?

Currently, there are still some catalytic cracking units under construction around the world, which are primarily used to improve the efficiency of oil refining and produce more light petroleum products. Regarding the layout of catalytic cracking units, the coaxial type and the stacked high-low type are the two common configurations. The specific form to be used usually depends on factors such as the factory’s layout, processing capacity, and the properties of the raw materials. Currently, there are no unified figures indicating which layout is used more frequently; this is usually determined by each refinery based on its own needs and conditions. As for advanced technologies, many new techniques have emerged in the field of catalytic cracking in recent years, such as: 1. Improving the selectivity and stability of catalysts, reducing by-products, and increasing the yield of main products. 2. Process optimization technologies to achieve more efficient energy use and reduce operating costs. 3. Develop more environmentally friendly technologies to reduce emissions and waste generation. 4. Use advanced process control systems to enhance the flexibility and reliability of operations. The application of these technologies helps improve the economic efficiency and environmental friendliness of devices, and they represent key areas for future development. .
