【Ten Years of Rapid Development in Chemical Equipment】985-2023: Sichuan-based company builds Anhui CarbonXin’s fourth phase plant with 2,000 tons/day Shenning furnace

Thread Content

Chemical processing equipment has seen significant development over the past decade; let’s praise the prosperity and strength of modern China. By contributing our ideas, we can foster more active participation from everyone. Haichuan becomes even better with your involvement – we welcome everyone to take part in discussions on this forum. Everyone should focus on safety and know how to handle emergencies. *********************************************The “Shenning Furnace” is a gasification unit developed by Shenning Group, featuring independent intellectual property rights. It serves as the core component of Shenhua Ningmei’s coal-to-oil project. This gasification furnace boasts high carbon conversion efficiency, high syngas yield, stable operation, and environmental friendliness. It can process various types of coal, overcoming the limitation of Siemens’ gasification furnaces, which could only handle high-quality coal – a factor that led to Siemens withdrawing from China’s coal gasification market. The Phase III project of Anhui Carbonxin has an annual production capacity of 500,000 tons of methanol. It utilizes the \"Shenning furnace\" powder coal gasification technology, with each furnace capable of processing 2,000 tons of coal per day. The project was constructed through EPC services provided by Donghua Technology, and it was successfully commissioned on April 28, 2022, with production starting immediately after that. This project represents the first instance of the \"Shenning furnace\" technology being put into operation since it was transferred to other parties. The Phase 4 project of CarbonXin will have an annual production capacity of 600,000 tons of ethanol; it will continue to use the \"Shenning Furnace\" powder gasification technology, with EPC construction carried out by Donghua Technology. Sichuan Kexin Electromechanical is responsible for manufacturing the gasifier, which is the core and key equipment of the gasification unit. This gasification furnace is the first Shenning-type furnace manufactured by Sichuan Kexin. It has an inner diameter of 4 meters, a length of over 20 meters, and a weight of more than 300 tons. Its walls are made of chromium-molybdenum steel through surfacing processes, and high standards are required for quality control. The internal structure of this furnace is complex, making it difficult to shape; there are a large number of pipe connections, and high requirements are placed on coaxiality. Additionally, the surface temperature of the equipment remains above 120 degrees Celsius for extended periods, which poses significant challenges during operation. Faced with various challenges, the staff at Ke Xin did not back down. Through the diligent efforts of all members of the project team, the main welds of the equipment passed the inspection on the first attempt; tasks such as heat treatment, testing, pressure testing, and painting were completed successfully without any issues, allowing for early delivery and providing a solid foundation for the smooth progress of the project. During the project implementation phase, with the strong support of companies such as CarbonX Technology, Shenyao Technology, Donghua Technology, and China Five Rings, the Kexin Mechanical and Electrical project team overcame numerous challenges. After more than ten months of hard work, the project was completed successfully, breaking the industry’s usual delivery time frame of 12–16 months. It arrived at the site safely on May 22nd and passed the acceptance tests without issue.
