Qiu Fei and his digital story

　　2, 3, 5, 7, 10, 20.
.
.
What does it mean? In the eyes of others, these are just a few irrelevant numbers, but in his heart, these numbers have a different meaning
.
Each of these numbers not only represents the process of the expansion of the silicone plant of Jiangxi Lanxingxinghuo Silicone Co.
, Ltd.
(hereinafter referred to as Elkem Xinghuo Silicones), but also an important witness on his road to tackling the synthesis device
.
He is Qiu Fei, Director of Synthesis Unit of Elkem Xinghuo Silicones Third Branch Plant, a master of monomer synthesis technology who has been specializing in synthesis units for more than 20 years
.

　　From 5 to 7, study hard and practice perseverance

　　Back in 2001, Qiu Fei, who had just graduated from school, came to Elkem Xinghuo Silicones and was assigned to a synthesis workshop with an annual output of 50,000 tons in the first organosilicon factory
.
Qiu Fei, who just entered the workshop, is like a blank piece of paper.
In order to master the job skills as soon as possible, he spends almost every day on the scene, concentrates on research, and humbly asks the master for advice
.

　　A few years have passed, and Qiu Fei's technical ability has become more and more mature
.
In 2005, it was catching up with the construction of Elkem Spark Silicone's annual capacity expansion project of 50,000 tons and 70,000 tons.
This was the first time they expanded production capacity through technical optimization on the basis of existing equipment
.
For Qiu Fei, this is a major breakthrough for the company and a rare opportunity for personal learning
.
He seized the opportunity to participate in the entire production expansion project.
For nearly three months, he ate and lived in the workshop, and repeatedly adjusted and tested process parameters with the team to find and solve problems
.
He refused to admit defeat sometimes jumped out of bed in the early morning, marched into the night, walked to the scene, and thought silently at the Tafu pipeline
.

　　After failing again and again, adjusting again and again, and re-testing again and again, after two years, Qiu Fei and his team finally achieved a one-time test run of the project with an annual production capacity of 50,000 tons and an expansion of 70,000 tons
.

　　From 2 to 3, consolidate the foundation and make steady progress

　　Shortly after the "Five Expansion Seven" project started, Elkem Spark Silicones carried out the construction of the project with an annual capacity expansion of 20,000 tons to 30,000 tons
.
As a young technical backbone, Qiu Fei began to lead the team to lead the "two expansion and three" technical transformation project
.
Because the installation of this "two expansion and three" project is relatively backward, it is another "hard bone" for Qiu Fei to crack
.

　　To improve the production capacity of old equipment through process technology optimization, it is necessary to overcome many "hard" problems, such as changing the process route, disassembling and assembling a large number of equipment parts
.
After the production capacity is increased, a more scientific and sensitive control system is needed.
Qiu Fei led the team to introduce a digital control system with an annual production capacity of 70,000 tons into the "two expansion and three" project, replacing and debugging a large number of instruments
.

　　In order to complete the project on time, Qiu Fei ran to the scene whenever he was free
.
The scientific control system they introduced also laid a solid foundation for the good and stable operation of the 30,000-ton per year plant
.

　　From 7 to 10 keep your feet on the ground

　　Through the continuous summarization of the intractable diseases in the actual production of the synthesis device, Qiu Fei explored a new set of production control processes, and through a series of technical bottleneck research projects, laid a theoretical and data foundation for the process operation of the synthesis device
.

　　With the construction and commissioning of the Elkem Spark Silicone plant with an annual capacity of 100,000 tons, Qiu Fei has been working non-stop in the technical transformation of the synthesis process of the new plant
.
Through raw material index control, production process control optimization, equipment selection and transformation, and technical transformation of device technology, Qiu Fei and his team have achieved effective use of fine powder, extended the start-up cycle days of the annual output of 70,000 tons and 100,000 tons of synthesis units, and improved production efficiency
.

　　It is worth mentioning that the content of dimethylformaldehyde is the main indicator to measure the synthetic yield and benefit of silicone monomers, and it is also a technical bottleneck that the domestic silicone industry has been difficult to break through
.
Qiu Fei has increased the production capacity of Xinghuo silicone plant by 10% and the content of dimethylamine by 2% through a variety of technological innovations
.
At that time, the benefit brought by just one percentage point increase was as high as 5 million yuan
.

　　In 2015, the company established Qiu Fei's organosilicon monomer synthesis skills master studio in Jiangxi Province, led by Qiu Fei
.
Up to now, the studio team has completed and applied for 9 patents, implemented more than 10 technical transformation projects, increased the company's annual income by 50 million yuan, and trained 36 outstanding synthesis operators through the training of apprentices
.

　　From 10 to 20, dare to go ahead

　　The monomer synthesis device is a complex gas-solid reaction process.
During the reaction, the content of silicon powder elements, the content of trace elements in the fluidized bed, the content of catalysts, the particle size distribution and particle size of silicon powder, etc.
, will affect the The selectivity and space-time yield of dimethyl to monomer synthesis
.
Finding the optimal combination from many influencing conditions and continuously tracking and adjusting is the key to a good synthesis reaction
.

　　After years of exploration and comparison, Qiu Fei has mastered a set of adjustment methods and detailed data suitable for the company, which ensures the safe, stable, high-yield and efficient operation of the synthesis device
.
At the same time, in order to meet the relevant requirements of low-carbon and environmental protection, Qiu Fei has successively implemented the technical transformation project of tail gas treatment of fine waste powder filter and the technical transformation project of improving the operation efficiency of cyclone system by continuously benchmarking with advanced enterprises around the world.
The device is more energy-saving and environmentally friendly
.

　　In 2021, Elkem Spark Silicones' new 200,000-ton/year monomer and supporting project will officially start construction.
This is another new growth journey for Qiu Fei, and he will continue to move forward on the road of excellence and pursuit of excellence
