Since the occurrence of major pollution accidents on the Minjiang River in 2004, Sichuan Chemicals has been attaching equal importance to environmental protection and production, relying on scientific and technological progress, implementing source control, and strengthening process supervision, achieving remarkable results. Over the past few years, Sichuan Chemical Holdings Group has invested 1.8 billion yuan to develop free gas recycling, carbon dioxide recycling, recycling of process condensate, fly ash recycling, water recycling technology, new catalysts and high-efficiency energy-saving equipment and waste heat recovery and utilization For other technologies, more than 20 technological transformations have been implemented in the three important chemical fertilizer and chemical production parks in Sichuan, Lutianhua and Sichuan Tianhua, achieving recycling of resources, products, and renewable resources. At present, the Group's three major ammonia plants under full load, the average comprehensive energy consumption per ton of ammonia dropped from 1167 kg of standard coal to 1085 kg of standard coal, which has met the 1140 kg standard of the national "Eleventh Five-Year" plan for large-scale synthetic ammonia energy conservation. The goal of coal. Compared with 2005, the Group saved 57,062 tons of standard coal, 261 tons of ammonia nitrogen, and 8.5 million tons of industrial wastewater.
In recent years, Yibin Tianyuan Group has invested a total of 1.4 billion yuan to carry out technical reforms. It consumes 540,000 tons of calcium carbide slag, 160,000 tons of coal ash slag, and 60 million yuan in economic benefits. The Group took the lead in independent research and development of dry process acetylene industrialization technology, achieving water conservation of more than 90%.
Chengdu Yulong Chemical Company has invested more than 200 million yuan in energy saving in recent years, making full use of high technology to phase out a group of old energy-saving and environmentally polluting old process devices. The amount of water consumed by a company to produce one ton of synthetic ammonia has gone from the past 500 tons. It has dropped to the current 10 tons, while saving 110 cubic meters of natural gas and 320 kilowatt-hours of electricity in the past, saving more than 200 yuan in cost.
According to reports, Sichuan Chemical strives to build a green chemical aircraft carrier with comprehensive control of pollution, rational use of resources, and recycling economy in 2010. Shang Yong, vice minister of the Ministry of Science and Technology, after visiting the demonstration site of the Sichuan Energy Chemical Group's energy-saving and emission reduction technology, said that Sichuan Chemical Industry vigorously promotes energy-saving and emission reduction, which is of great significance for the rest of the country.

The industrial unit's industrial added value energy consumption has dropped by more than 10%, and the comprehensive energy consumption level of key ammonia plants has reached the national “Eleventh Five-Year Plan†energy saving planning target requirements in advance. On May 5th, the reporter learned from Sichuan Provincial Industrial Energy Saving and Emission Reduction Technology Demonstration Site Conference. The energy consumption of the Sichuan chemical industry showed an overall decline, and the energy consumption per unit of added value fell more than 10%. Shang Yong, vice minister of the Ministry of Science and Technology, gave high praise to Sichuan Chemical Industry for relying on science and technology to promote energy conservation and emission reduction.
