【Haichuan Chemical Salary Updates】Handover of the second-phase reform project for coal-to-gas production at Yangzi Petrochemical
Thread Content
In early November, the second-phase renovation project for coal-to-gas production at the Yangzi Petrochemical Plant was officially completed. Based on the successful operation of the first-phase demonstration project, this project involves adding another gasification furnace, enabling dual-furnace switching operation to ensure the stability of hydrogen supply in the region. The new gasifier adopted in this project uses the \"single-nozzle cold-wall pressurized coal gasification technology\", namely the SE-Eastern type, which exhibits strong adaptability to low-quality coal types with high sulfur, high ash content, and high ash melting point – characteristics that are common in China. The new gasifier adopted in this project uses the \"single-nozzle cold-wall pressurized coal gasification technology\", namely the SE-Eastern type, which exhibits strong adaptability to low-quality coal types with high sulfur, high ash content, and high ash melting point – characteristics that are common in China. The Yangzi Petrochemical coal-to-gas project is implemented in two phases. The industrial demonstration of this complete set of technologies will be carried out in Phase 1 ； In the second phase, SE powder gasification is used to completely replace natural gas steam reforming for the production of syngas; in other words, a second gasifier is built on the basis of the first phase. Due to the fact that the framework of the gasification furnace in this second-phase renovation is over 100 meters tall, it involves a large amount of work related to lifting heavy equipment and welding special pipelines; as a result, the technical requirements for this renovation are high and the construction is quite challenging. To this end, the project team repeatedly adjusted the construction schedule in the initial stages and established a comprehensive set of construction and safety management systems. The project team members are fully committed, checking on the progress of material delivery on a weekly basis and ensuring strict control over construction quality. During the renovation period, the chemical plant implemented a continuous supervision system to strictly control operational risks, promptly rectify unsafe construction practices, and minimize safety hazards. They organized technical personnel involved in equipment, instruments, and processes in advance to train the operators in accordance with the required guidelines, covering topics such as the modifications to be made, process updates, and key operating points. They linked the effectiveness of this training to performance assessments, thereby ensuring good training results and laying a solid foundation for the commissioning of the second-phase renovation. After the project is implemented, Yangzi Petrochemical will have 2 gasifiers along with the corresponding process equipment; each gasifier will be able to process 1,000 tons of coal per day, producing 70,000 standard cubic meters of synthetic gas. At the same time, the core unit, the gasification furnace, will operate under a configuration of one unit in use and one as backup, thereby enhancing the system’s resilience to risks. This allows for a better response to unexpected abnormalities, ensures the long-term stable operation of the facility, improves the competitiveness of the company’s coal-to-gas production units, and contributes to further stability
Yangzi Petrochemical launches new project to convert residue oil into gasoline and diesel – Longzhong Petrochemical Network Energy, 1109, 17:19. At the end of October, the heavy oil lightening transformation project at Yangzi Petrochemical’s refinery was put into full operation. This project enables the conversion of low-quality residue oil into lighter oils through thermal cracking, followed by further separation of these lighter oils to produce high-value products such as gasoline, diesel, wax oil, dry gas, and liquefied gas.
Yangzi Petrochemical’s 1-butene products exported to Australia for the first time; high-end polyolefins and engineering plastics 1108, 11:30. Source: Sinopec News Network. This article does not represent the views of Yahuazheng Consulting; it is reproduced solely for readers’ reference. On November 5, a container ship carrying 12 tons of 1-butene products from Yangzi Petrochemical exported to Australia for the first time, marking the successful establishment of a route for exporting this company’s 1-butene products to overseas markets. This represents the first step taken by Yangzi Petrochemical – based on the export of 1-butene products – to establish a platform for product exports, strengthen cooperation, and take various measures to explore overseas markets and overcome the problem of overcapacity in the domestic market. It lays the foundation for future product exports.
In September, news came from Sinopec Chemical Sales Company that a company in Australia needed to purchase 12 tons of 1-butene. Although the order is small, it is key to whether Yangzi Petrochemical can secure more orders in the future. Yangzi Petrochemical attaches great importance to the export of 1-butene products. To carry out this business effectively, it has worked closely with the Jiangsu branch of Sinopec Chemical Sales Company, leveraging their respective strengths and carrying out extensive preparatory work. It prepared various documents required for customs clearance, such as instructions for proper container handling and transportation, safety data sheets for chemicals, and statements regarding the safe filling and transportation of hazardous cargo containers. The company also communicated with foreign clients to fully understand their product requirements and related circumstances, and coordinated on product specifications and logistics routes, thereby ensuring a smooth export process. In early November, traffic controls were in place during the Shanghai International Import Expo. According to the regulations, the deadline for hazardous materials vehicles from outside the region to enter Shanghai Port is 24:00 on November 5. To avoid delays in shipping schedules and ensure the smooth shipment of 1-butene products, Yangzi Petrochemical took thorough precautions in advance regarding factors that might affect the product shipment. It communicated with the freight company responsible for this transport, providing detailed information on the permits required prior to loading as well as safety precautions during the loading process. Technical checks were also carried out to confirm that the loading interfaces were compatible. At 2:30 p.m. on November 5, after on-site inspection by the customs and inspection officers at Nanjing Port, 12 tons of 1-butene were successfully packaged and shipped out, destined for the port of Shanghai from there to Australia.
