As a major industry in the oil and chemical industry, the chlor-alkali industry in China has continued to grow rapidly in recent years. In 2005, the output of caustic soda reached 12.4 million tons, an increase of 21.4%; PVC production reached 6.49 million tons, an increase of 27.6%. However, China also faces tremendous pressure from safety and environmental protection due to the rapid growth of the chlor-alkali industry. Li Wanchun, deputy director of the State Administration of Work Safety in the State Administration of Work Safety, pointed out that, according to the statistics on hazardous chemicals accidents in China since 1987, the proportion of chemical accidents involving chlorine hazardous chemicals accounted for 22% of all accident-causing chemical accidents. The highest accidental chemical substance. It is imperative to vigorously strengthen the work safety management in the chlor-alkali industry. Regarding the environmental problems caused by calcium carbide process PVC, Dage Ruiwu, president of the World Vinyl Council, believes that currently it is impossible for the calcium carbide process to produce polyvinyl chloride to meet the emission requirements of developed countries. China has developed due to the shortage of petroleum resources. The production of polyvinyl chloride by calcium carbide method requires great efforts to reduce the pollution emissions.
Zhou Xianhui, director of the Environmental Protection Office of the China Petroleum and Chemical Industry Association, pointed out that measures to solve the industry's sustainable development problems include vigorously promoting circular economy strategy, adopting a chemical industry development path, accelerating independent innovation, and using high and new technology, clean production, and advanced and applicable technologies. Traditional industries with high energy consumption and heavy pollution limit and eliminate backward production capacity, processes and technical equipment.
The largest proportion of accidents involving chlorine hazardous chemicals
The reporter learned from the World Chlor-alkali Industry Sustainability Conference 2006, held in Beijing on April 24th to address the increasingly severe safety and environmental constraints faced by the chlor-alkali industry, that chlorine-related hazardous chemicals accounted for 1987 accidents. The proportion of dangerous chemical accidents is 22%, which is the highest among all chemical substances.
