The Guangxi Huayi butanol/octanol project has successfully produced high-quality products

Thread Content

Recently, the butanone-octanol unit of the 320,000 tons per year butanone-octanol and acrylate project at Guangxi Hua Yi New Materials Co., Ltd., which was undertaken under EPC general contracting by China National Chemical Engineering Corporation Hualu Company, was successfully commissioned after its initial feeding. It has been producing high-quality products such as n-butanol and octanol in a stable manner, with all process parameters under precise control and all key operational indicators meeting the required standards. This achievement has set a new record for the fastest construction time of a butanone-octanol plant of this scale worldwide, demonstrating the company’s strong capabilities in engineering design and general contracting management. Located in the Petrochemical Industrial Park of Qinzhou Port Economic and Technological Development Zone in Qinzhou City, Guangxi Zhuang Autonomous Region, this project is a strategic cornerstone for the Huayi Qinzhou facility to achieve integrated development and to drive the transformation of its industrial structure toward high-end new materials sectors. Among them, the butyl and octyl alcohol production facilities utilize the internationally advanced Zongxin Wanfeng S30 high-selectivity low-pressure carbonylation technology. This technology features a low consumption of rhodium catalyst, an extremely high ratio of the desired isomer to the undesired one, high product purity, as well as significant advantages in terms of energy efficiency and environmental friendliness. The butyl alcohol and octyl alcohol produced by these facilities are essential key raw materials for industries such as plasticizers, coatings, synthetic fragrances, and pharmaceutical intermediates; they have wide market applications and considerable strategic value. Since the project commenced on January 19, 2026, the company’s project team has aimed to excel through diligent effort, making full use of the advantages of the “T+EPC” model. By coordinating resources from patent technology providers, key suppliers, and construction subcontractors, the team has worked together with the client to carry out critical preparatory tasks such as ensuring system airtightness, verifying instrument interlocks, and accurately loading catalysts. In the face of the technical difficulties and detailed challenges encountered during project construction, the project team established special task forces to conduct in-depth discussions and implement targeted solutions, thereby resolving various issues efficiently. This ensured that each construction step was carried out strictly in accordance with the scheduled timeline and that all specifications met the design requirements. As a result, the project was completed on schedule, enabling it to enter a new phase of stable operation. Moving forward, the project department of Hualu Company will continue to uphold the concept of “integrated production and operations”. By ensuring the stable operation of its facilities, it will continuously optimize operational management and enhance overall efficiency. This will help to further strengthen the company’s brand reputation in the Beibu Gulf region, providing robust impetus for the company’s high-quality development and contributing more Hualu efforts toward the upgrading of the local new materials industry.
