Chen Minghai, secretary-general of the China Petroleum and Chemical Automation Application Association, said that at present, domestic DCS (distribution control system) has been successfully applied to 5 million tons/year of oil refining, 300,000 tons/year of synthetic ammonia, and 520,000 tons/year of large-scale oil and urea. Chemical installations; advanced control technologies and information management systems have been well applied in large-scale production processes and enterprise management, and have achieved considerable economic benefits; the automation level of the petroleum and chemical industries has made great progress, from manual development to automatic Control, from the development of low-level single-loop control to advanced and complex system control, optimization control and management and control integration. Practice has proved that automation and information technology are an effective means to tap potential and increase efficiency.
However, there are still some problems in the field of domestic petroleum and chemical automation. The main manifestations are: DCS of large-scale devices is still mainly imported; some advanced control software has been developed in the country, but most of them fail to achieve standardization and commercialization; the technology of domestic field instrumentation The level and level of quality are generally different from those of foreign countries. Many imported products are still in the 1980s and 1990s. The intensity of digestion, absorption, and reinvention is insufficient; most of the computer applications are still device-level, information systems, and computer integrated production systems. There is a lack of investment, and there is no obvious effect.
Chen Minghai believes that China's large-scale oil and chemical companies should vigorously promote, expand and accelerate the construction of integrated enterprise automation systems, and improve the level of enterprise management and control integration, so as to reduce raw material and energy consumption, reduce costs, increase product output and quality, and improve the overall enterprise The purpose of efficiency, and effectively improve the competitiveness of enterprises.
Through technology introduction, digestion, absorption, and re-innovation, China's petroleum and chemical industries have greatly improved the level of automation and information technology equipment and application management, and are currently keeping pace with foreign countries. This is the information uploaded by the 8th Annual Technical Conference of China Petroleum and Chemical Automation held in Zhengzhou City from June 21st to 23rd.
