The reporter learned from the safety supervision department of Shandong Province on November 17th that the province will accelerate the advancement of high-risk process automation and control of chemical companies through typical approaches and strict access control. By the end of 2010, all chemical plants that employ dangerous processes will Realize automatic control and safety interlock.
From November 5th to November 6th, Shandong Province held an on-the-spot meeting on the automatic control and transformation of high-risk process chemical companies in Qingzhou City. The site visited the high-risk technological transformation of Qingzhou Hengfa Chemical Co., Ltd. After the company’s original process was automated, only five employees were responding to the job, reducing the number of employees in each class by 4 and reducing the total number of employees in the three classes by 12 persons. Because the pressure, flow, and temperature are automatically adjusted and controlled by the instrument, the process is stable, the control accuracy is improved, the product yield is increased by one percentage point, and the risk of manual operations is greatly reduced. According to statistics, the cost of renovation will be fully recovered within a year or so.
Shandong Province strictly controls the access to safe production of hazardous chemicals companies and hazardous chemicals construction projects. Whether or not to install chemical production automation and safety control systems as a condition for changing (sending) safe production licenses. Newly built, reconstructed and expanded chemical projects involving dangerous processes will not be subject to safety approval without automatic control systems and safety interlocks.
Shandong is a large chemical province. Chemical companies generally set up factories earlier. Most of the chemical pressure, temperature, and liquid level of small and medium-sized chemical companies established before 2000 are controlled by manual control. Processes such as the release of reaction materials depend on manual labor. Operation, no automatic control and safety interlock systems are installed, and the intrinsic safety level of the production process equipment is low. Since 2002, there have been a total of 110 accidents in Shandong chemical companies, 52 accidents related to the lack or imperfection of automatic control and safety interlock alarm systems, accounting for 47.3% of the total number, and 18 major accidents with more than 3 deaths. There were 7 accidents related to this, accounting for 38.9% of the total. It is imperative to accelerate the implementation of automatic control and safety interlocking of dangerous chemical processes such as chlorination, nitration, sulfonation, polymerization, fluorination, and hydrogenation.
