The full process of the 45,000 m3/h syngas technical upgrade project at Lu’an Chemical Qilu Yihua Company has been completed
Thread Content
On December 23, 2025, the entire process of the 45,000 m3/h syngas technology upgrade project at Qilu No.1 Chemical Company of Lu’an Chemical was completed, resulting in the successful production of octanol. At 8 a.m. on December 24, after multiple rounds of rigorous testing, the purity of the octanol product reached 99.63%, with its key parameters meeting the standards for Type I products; this marked the official entry of the project into a new phase of operation. The commissioning milestones for the syngas technical upgrade project are as follows: on November 28, the boiler will start producing steam. On December 15, the air separation unit supplied oxygen to the gasification unit. On December 16, the first ignition of the gasifier during its heating-up was successful. On December 20, the gasifier achieved successful first-time feeding and produced qualified syngas. On December 23, the butyl acetate plant produced octanol products, achieving the production target one week ahead of schedule. The technical renovation project for Qilu Yihua’s 45,000 standard cubic meters per hour syngas plant is the key project for the company to achieve the upgrading and development of its facilities. The project utilizes domestically leading process technologies to comprehensively upgrade the existing facilities; the synthetic gas upgrade at Qilu First Chemical Plant employs Jinhua furnaces (two Jinhua furnaces, one in operation and one as a backup). Replacing the fixed-bed batch gas production process, and integrating CO shift, low-temperature methanol washing, PSA hydrogen production, and sulfur recovery, to achieve an effective synthesis gas production capacity of 45,000 m3/h. Huisheng Engineering EPC. The Syngas Technical Renovation Project of Qilu No.1 Chemical comprises three parts: syngas technical renovation, safety and environmental protection upgrades for butanol and octanol production, and renovation of the dedicated railway line. After the project was put into operation, the energy consumption associated with the production of octanol decreased, while emissions of sulfur dioxide, nitrogen oxides, and chemical oxygen demand were significantly reduced, resulting in substantial improvements in environmental performance.
