From "Pioneer" to "Almighty King" - Documentary of BDO Engineering Design and Development of Hualu Company

　　In late May, China Chemical Hualu Engineering Technology Co.
, Ltd.
started the engineering design of the 1,4-butanediol (BDO) unit of the Hebei Bohang New Material Biodegradable Material Integration Project, marking that Hualu Company has become the only domestic company with all the Engineering company with BDO route design performance for industrial maleic anhydride process
.
Starting from the process package and engineering development of the first BDO device in China, Hualu has been deeply involved in the design of BDO and its derivatives for more than 20 years, accumulated rich experience in engineering design and construction, and achieved a number of breakthroughs with its excellent technical strength.
and innovation
.

　　Tech breakout breaks blockade

　　BDO is an important basic organic chemical and fine chemical raw material
.
In the 1980s, China's BDO plant engineering design was subject to the technical blockade of foreign companies for a long time, and independent development was imminent
.
At that time, a group of technicians from Hualu Company invested in BDO technology research and engineering development
.
In 1999, Shanxi Sunway Group decided to build the country's first BDO project with an annual output of 25,000 tons
.
In the absence of technical data, Hualu Company used foreign second-hand equipment to integrate, optimize and innovate the entire process, using foreign second-hand equipment, starting from the original material, heat, and process simulation calculation, to overcome many technical and engineering problems, creatively The process package and engineering development task of the "25,000 tons of BDO industrialized production technology per year" of the acetylenic aldehyde method has been successfully completed, and a breakthrough has been achieved in China's BDO industrialization plant
.

　　In November 2006, the industrialized production technology of 25,000 tons/year BDO won the first prize for scientific and technological progress in China's petroleum and chemical industry, and then the project was awarded the National Excellent Engineering Design Silver Award by the Ministry of Construction
.

　　Maintain a single set of production capacity records

　　At the same time, Hualu Company followed up the application of maleic anhydride method BDO technology.
In 1999, it first undertook the design of 10,000 tons/year BDO project of Shandong Donggang Fine Chemical Co.
,
Ltd.

　　The domestic production of BDO is mainly based on the acetylenic aldehyde method and the maleic anhydride method.
The patent providers include Shanxi Sunway, INVISTA, Hong Kong Guanda, Italy CONSER, and British David (Johnson Matthey)
.
Through continuous upgrading and optimization, Hualu has accumulated a lot of engineering experience in the engineering design of the BDO project, and has won the recognition and praise of the owners
.

　　"At present, 14 BDO projects that we are responsible for engineering design have been completed and put into production, with a total annual production capacity of 800,000 tons, accounting for 30% of the total domestic annual production capacity, of which the acetylenic aldehyde method accounts for 80%
.
" Zhang Shehui, deputy director of the Department of Commerce of Hualu Company Told reporters that the BDO project being implemented by the company has an annual production capacity of nearly 900,000 tons
.

　　Relying on the advantages of technology and engineering practice, the BDO project undertaken by Hualu Company has maintained the record of the largest single-unit production capacity in China
.
The 200,000-ton/year BDO and 60,000-ton/year polytetrahydrofuran (PTMEG) integration project of Xinjiang Guotai Xinhua Chemical Co.
, Ltd.
was completed in 2018, with a single set of BDO production capacity of 100,000 tons/year
.
The new material industry chain integration project of Tongde Kechuang Materials Co.
, Ltd.
, which started in June last year, has a capacity of 120,000 tons per year for a single BDO unit
.
The BDO integration project of Inner Mongolia Sunway New Materials Co.
, Ltd.
started in March this year.
Hualu Company undertook the general contract for the project design of the main BDO plant of the acetylenic aldehyde method and its supporting facilities.
Currently the largest in the country
.

　　Completion of the plant to achieve production and efficiency

　　In recent years, with the rapid development of downstream industries such as degradable materials, automobiles, electronics and clothing, the domestic BDO market has become popular again, and companies have expanded investment in BDO projects.
The total annual production capacity of the "14th Five-Year Plan" will exceed 19 million tons
.

　　Hualu Company uses advanced technology and equipment to ensure that the completed project can reach production and efficiency as soon as possible
.
After the 200,000-ton/year BDO plant of Xinjiang Guotai Xinhua Chemical Co.
, Ltd.
designed by the company was put into operation at the end of 2018, it reached the design load after one month, and then maintained a 120% overload operation state, with a comprehensive energy consumption of 720 kg of standard coal/ton, excellent The industry advanced value of 950 kg standard coal/ton
.
Moreover, BDO is of high quality and less impurities, with a purity of over 99.
97%
.

　　The relevant person in charge of Hualu Company said that they will give full play to their professional and technical advantages in the field of BDO and rich experience in engineering construction management, focus on the coordination of key aspects of project operation, optimize resource allocation, continue to improve the quality of project operation, and provide owners with the whole life of the project.
Cycle of quality service
