Fine chemical industry urgently needs intelligent technology to make up for shortcomings

at the time when the construction of intelligent factories in petrochemical enterprises is in full swing, the intelligent level of China's fine chemical enterprises needs to be strengthened. Many enterprises still use traditional processes and equipment, and the construction of digital instruments, equipment and information systems is obviously lagging behind. At the Symposium on the development of digital transformation of fine chemical enterprises held in Beijing on January 11, the participants believed that the digital transformation of fine chemical industry has great potential, and chemical enterprises should strengthen cooperation with solution suppliers to explore their own intelligent solutions

Dr. Kou Huaicheng, director of Hangzhou Hollysys intelligent factory business department, believes that at present, the development of China's fine chemical industry is relatively backward, with a fine chemical industry rate of 45%, far lower than 75% - 90% in developed countries such as Europe and the United States; Moreover, there are many middle and low-grade products, few high value-added products, and the degree of automation and informatization is low. We should make full use of information technology to promote the development of fine chemical industry in the direction of small batch, multi variety, flexibility, diversification, personalization and specialization

Tan Jianrong, an academician of the Chinese Academy of engineering, believes that the basis and goal of developing intelligent manufacturing, including the chemical industry, is lean production. The core of lean production is zero inventory and rapid response to market changes, that is, multi batch and small batch production. Lean production and quality engineering are the premise and foundation of intelligent manufacturing. First of all, lean production should be achieved through robot technology and artificial intelligence technology. The goal of intelligent manufacturing is to make production more lean. Tan Jianrong said

Wu Zhenyi, chairman of the fine chemical industry professional committee of the Chinese society of chemical industry, also said that the digital transformation of fine chemical industry is very necessary. In the recent environmental storm in China, many fine chemical enterprises have been affected, which also shows that fine chemical enterprises have great demand for management improvement. Fine chemical industry has the characteristics of small batch and multiple varieties. It should be combined with IOT intelligent manufacturing to improve the intelligent manufacturing level of China's fine chemical industry, so as to improve production efficiency and safety and environmental protection level. Wu Zhenyi said

several short boards need to be filled

previously, many safety production accidents in chemical enterprises in China were related to the lack of automatic control system. In particular, in the production process of fine chemicals, there are many unit operations, large process differences, long process flows, and most of them are intermittent or semi continuous and small batch production, which involves high temperature, high pressure, strong exothermic reactions, and has high requirements for management and equipment. However, due to the neglect of automatic control system and management by relevant personnel, safety accidents in fine chemical production occur frequently

not only safety production, but also the backward level of automation and informatization has also led to the low production efficiency of fine chemical enterprises to ensure good sealing. We have previously compared a domestic chemical enterprise with its foreign counterparts. The number of devices on both sides is the same, but the number of employees of domestic enterprises is four times that of foreign enterprises. Liaoyouhui, general manager of batch Business Department of Beijing Hollysys Industrial Software Co., Ltd., said

Kou Huaicheng expressed his views on the digital transformation path of fine chemicals. He believes that the industry urgently needs to make up lessons in the field of automation. At the same time, it should strengthen the promotion of information technology and the exploration in the field of intelligence, ensure the uniqueness of the platform at all levels or the uniqueness of the main system, and comprehensively apply the current mature technologies and software at the automation level, such as automatic equipment, DCS (batch)/plc, optimal control software, etc; The management level starts from the key points in the business (flexibility/security, etc.) to realize the digitization from the equipment to the management level; Qualified enterprises should also realize the informatization of group management and office; Search for intelligent pilots at all levels

Wang Hua, deputy chief engineer of China Petroleum Planning Institute, believes that intelligent construction is a long-term and complex process, which requires a lot of research work, active pilot practice, and gradually from local intelligence and professional intelligence to factory intelligence and enterprise intelligence. We should research and develop intelligent integrated service platforms and CPS with chemical characteristics, strengthen the introduction and training of intelligent manufacturing talents, and the development and application of new technologies

significant implementation results

helping fine chemicals improve the level of intelligent manufacturing is also the focus of suppliers. Fang Lei, deputy general manager of Hollysys group and President of Hangzhou Hollysys Automation Co., Ltd., said that Hollysys group formed a systematic Hollysys digital factory solution by combining the key technologies and directions of digitalization and the characteristics and current situation of fine chemicals. Based on the holicube industrial interconnection platform, Hollysys has integrated four complete systems of data standards, information security, knowledge management and process planning to form five comprehensive solutions for the digital factory, including production management scheme, park management scheme, process optimization scheme, basic control scheme and intelligent monitoring scheme, so as to realize the deployment of the group's digital factory in an all-round way

liaoyouhui said that in the development process of China's new energy materials industry, Hollysys' overall solution for the digital transformation of fine chemicals can be optimized and improved in many fields for the main problems existing in enterprises, especially in terms of personnel and production. For example, in the feeding process, the system can solve the problems of wrong feeding, missing feeding, more feeding, less feeding, etc; In temperature control, it can increase the stability of dropping and ensure the accurate control of temperature

many chemical enterprises also shared the achievements of intelligent manufacturing at the meeting. Dongyue Group applied APC optimization control system and MES system to deal with the control pain points of fluoride production process, which brought economic benefits to the enterprise. Dr. Chen Yue, chief engineer of Dongyue Group, said that in the production of fluoride polymerization, the application of APC can solve the automatic control of multivariable system, improve the stability of product quality, and realize the optimization of personnel positions. It has the advantages of not affecting the original DCS logic of the system, realizing automatic temperature rise and fall control, strong adaptability of the control system, reducing kettle temperature fluctuation, one key polymerization and so on

dongzhijie, chairman of mutual benefit chemical industry, said that in the acrylic emulsion industry, 500 employees are required to maintain production for every 100000 tons of lotion produced by peers, while mutual benefit chemical company only needs 80 employees to produce after using the fine chemical batch and MES system, which fully reflects the actual benefit and huge economic benefits brought by the enterprise after using the achievements of digital made in China 2025 and continuous plant construction

Jiao Xiao, deputy general manager of Beijing Hollysys Industrial Software Co., Ltd., is also difficult to decide. Ying said that Hollysys will use new technologies and models of industrial interconnection to implement digital networking and intelligent upgrading, further reduce operating costs, improve production efficiency, improve product quality, reduce energy consumption and emissions, and optimize industrial synergy
