In recent days, Anqing Petrochemical has been actively engaging in brainstorming sessions and organizing technical teams to address the various challenges that have been hindering the smooth operation of the coal gasification plant. Building on the success of the first half of the year's 30-day stable development target set by the headquarters, the company successfully met the second half of the year's 60-day goal on October 7th. This achievement marks a significant milestone in the plant's operational journey.
Shell coal gasification technology is known for its wide adaptability to different types of coal, high coal conversion efficiency, and environmentally friendly characteristics. Its practical application has drawn considerable attention from industry stakeholders. As one of the first Chinese companies to trial this large-scale fertilizer production technology, Anqing Petrochemical has faced some engineering challenges that require gradual improvement. Earlier, the equipment experienced frequent parameter fluctuations and some components suffered from severe wear, which posed difficulties for continuous operation.
To tackle these issues, Anqing Petrochemical established a specialized, fast-response technical team comprising engineers, technicians, and frontline operators who are constantly on-site, working together to find effective solutions. Gasification furnaces demand a high level of cleanliness, as large clinkers can easily cause pipeline blockages. In response, the company installed two fiber separators at critical points to ensure unobstructed flow.
Given the variability in coal batches, impurities such as large clinkers and fibers often appear. To manage this, the team regularly sent personnel to clean the coal storage area and conducted thorough inspections of key equipment. They also implemented special protection measures tailored to the actual operating conditions of the gasification unit’s pumps.
In addition, the team addressed issues with the gasification burners and ash removal systems through technical upgrades and assigned dedicated personnel to provide round-the-clock support. During abnormal operations, operators quickly switched from automatic to manual control and adjusted the production load based on the device’s status, ensuring the optimal oxygen-to-coal ratio and maintaining stable, smooth operation of the system.
