China Petrochemical’s PDH pilot plant was completed at Beihai Refining & Chemical Complex!
Thread Content
On July 24, the PDH pilot plant of Sinopec was completed at Beihai Refining & Chemical Company. This project represents Sinopec’s first PDH pilot plant with independent intellectual property rights; it holds strategic and practical significance for breaking the foreign monopoly on PDH technology, enhancing Sinopec’s international competitiveness in this field, and advancing the \"oil conversion\" process at Beihai Refining & Chemical Company. Since the construction of the PDH pilot plant began on April 26, 2023, all parties involved in the project at Beihai Refining & Chemical have strictly followed the company’s requirements for its construction, upholding a work style characterized by rigor, precision, and practicality. Through scientific organization and strict management, they have continuously improved the construction plans and optimized the scheduling of construction activities. They overcame difficulties such as long lead times for equipment and material procurement, as well as the impacts of high temperatures, extreme heat, and typhoons. By working together and staying committed to their duties, and by utilizing methods such as factory-prepared components and modular installation, they advanced the project progress steadily, focusing on key milestones. As a result, the project was completed one day ahead of schedule, laying a solid foundation for carrying out PDH pilot tests. Next, Beihai Refining & Chemical Company will carry out thorough preparations for commissioning, work closely with all involved units, and work together to ensure the successful first-time startup of the plant.
This is just the first step. . I saw that pilot plant flow diagram; it starts with propane as the raw material, and crude propylene is produced as a result. Strictly speaking, neither of these can be considered PDH
It’s the propane feedstock, and then crude propylene is produced? ? ?
Crude propylene purification is a mature process, and it is estimated that it can be handled using existing gas separation unit facilities.
Looking at the flow diagram, it indeed goes to the degassing unit
On the flowchart, it’s like this: the crude propylene goes to the degassing unit
It is mainly a dehydrogenation reaction; there’s no need to test the gas phase
