Xinye Nenghua’s 200,000 tons/year BDO (1,4-butanediol) Phase II project came online

Thread Content

The second-phase project of Xinye Nenghua Company, with a capacity of 200,000 tons per year for BDO (1,4-butanediol), was brought online successfully in one go, producing high-quality BDO with a concentration of 99.75%. This achievement lays a solid foundation for the company’s diversification efforts in the downstream applications of BDO as well as in the development of new products. Xinye Nenghua Company’s 200,000 tons per year BDO project is a key initiative, carrying the important mission of promoting local economic development, optimizing the industrial structure, and enhancing technological innovation capabilities. The company’s first-phase BDO production project with an annual capacity of 60,000 tons was completed and put into operation in 2019; the facility has been operating steadily, achieving its full production capacity and efficiency targets. The second-phase 140,000-ton/year BDO project has a total investment of 1.8 billion yuan. It includes 38 different plant units such as an acetylene plant, a formaldehyde plant, and a BDO plant, covering various fields such as civil engineering, piping, and electrical systems. The construction period is 18 months. From the initial stage of project design, the company adhered to high quality and standards in terms of safety, environmental protection, and energy conservation. In terms of environmental protection, all volatile organic exhaust gases were thoroughly treated, with the level of total non-methane hydrocarbons kept below 20 mg, achieving a **leading standard. Exhaust gases such as acetylene and hydrogen were completely recovered, resulting in cost savings of around 5 million yuan per year ； BDO distillation employs a single-unit design, which reduces energy consumption by about 10%; after the purification of waste liquids, the BDO content is reduced to 10–15%. Through continuous process optimization, the competitiveness of BDO products in the market has been enhanced. During the construction period, Xinye Nenghua Company established a project construction team, which included 6 specialized sub-teams for safety and environmental protection, civil engineering, technology, etc. Key professionals were selected to ensure thorough management of all aspects of the project construction, including design, safety, quality, schedule, and cost control. During this period, leaders such as Ma Jinrong, a member of the Party Committee of Xinye Group, its deputy general manager, as well as the Party Secretary and chairman of Xinye Energy & Chemical Company, visited the project sites on multiple occasions to gain a detailed understanding of the project’s progress, address difficulties on the spot, and ensure strict control over safety and quality. They emphasized the need to stick to the scheduled timelines, allocate sufficient resources, organize work scientifically, and clarify responsibilities in order to accelerate the project’s progress and improve its efficiency. After the project was completed at the end of July this year and handed over to CCCC for commissioning trials, the company established a command team for Project BDO Phase II. It assigned top experts from various fields to strengthen coordination in areas such as personnel management, technical guidance, safety control, and supply support. The team developed implementation plans for commissioning, organized training for employees, clarified the steps involved in starting up the operation, and ensured that everyone was well-versed in the relevant procedures, thereby further enhancing the safety awareness and professional skills of all staff members. Entering this critical phase of full-scale operation, the employees working at various positions in the Phase II BDO plant demonstrated a great spirit of resilience and determination in the face of low-temperature conditions; they were willing to take on challenges head-on. Professionals in each position worked overtime to conduct thorough safety inspections of the BDO plant, covering aspects such as process pipelines, equipment operation, and process interlocks. They also carried out proper safety assessments, took measures to protect equipment from cold and freezing conditions, and addressed any leaks found, thereby ensuring the safe and successful commissioning of the BDO plant in just one attempt.
