ENVIRONMENT PRIORITY
The company adheres to the ecological civilization thought of "not only gold and silver mountains, but also green water and green mountains", environmental protection priority strategy and green development concept, formulates and implements the "smoke must be eliminated, dust must be removed, fire must be extinguished, water must be collected, and waste must be used" twenty-character environmental protection renovation strategy, and pays close attention to the renovation of supporting facilities focusing on environmental renovation and Yangtze River three phosphorus investigation, green development has achieved remarkable results.
Yellow phosphorus environment comprehensive improvement project -500 tons/day lime kiln
Yellow phosphorus tail gas purification device
Since the 1990 s, the development and utilization of medium and low grade phosphate rock have been carried out one after another, the comprehensive utilization of yellow phosphorus water quenching slag, the purification of yellow phosphorus tail gas, the recovery and utilization of waste heat from phosphoric acid and phosphorus pentoxide production units, and the ball formation of mineral powder and coke powder have been recycled after effective treatment, and there is no external discharge.
During the "14th Five-Year Plan" period, the company successively invested 1 billion yuan in environmental protection and governance, strictly compared with the technical guidelines for the "three phosphorus" investigation of the Yangtze River, and vigorously rectified the production process and environment, basically achieving the predetermined goals of "smokeless, fire-free, dust-free, tasteless" and "the same production and parking" in the production site environment. Not only did the environmental protection meet the emission standards, the three wastes treatment and comprehensive utilization results were obvious, and reduce the impact on the surrounding environment, green development has been in the forefront of the industry. In October 2020, it was named the fifth batch of "green factories" by the Ministry of Industry and Information Technology ".
8000 m/h Yellow Phosphorus Tail Gas Comprehensive Utilization (Power Generation) Project
2023
In 2023, the 8000m³/h yellow phosphorus tail gas comprehensive utilization (power generation) project was completed and put into operation, achieving 100% recovery and utilization of upstream yellow phosphorus electric furnace tail gas.
2020
In July 2020, the main plant area and the chemical workshop No. 5 (a total of two sets) of the yellow phosphorus tail gas purification device were completed and put into operation, achieving the goal of "smokeless and fireless" in the production area, greatly improving the visual environment of the plant.
2019
In June 2019, the completion and acceptance of the smoke treatment project for the yellow phosphorus furnace was completed, marking the beginning of a new era in the collection and treatment of smoke from yellow phosphorus furnace slag.
2015
In 2015, the company carried out energy-saving and emission-reduction modifications to the original 5000 tons/year phosphorus pentoxide production unit, and recovered the heat from yellow phosphorus combustion for steam production (1t/h).
2013
The company is constructing a comprehensive utilization project for 80,000 tons/year of phosphate powder and coke powder, fully utilizing the phosphate powder and coke powder generated from yellow phosphorus production, while also using the yellow phosphorus tail gas produced by the company's 7# and 8# yellow phosphorus electric furnaces as a heat source for comprehensive utilization.
2012
The company has introduced Italian Fucas technology to build a comprehensive utilization project for yellow phosphorus tail gas treatment - a 500 tons/day lime project, which has increased the comprehensive utilization rate of the company's yellow phosphorus tail gas to over 95%, and utilizes the residual heat from the lime kiln to produce steam (8t/h);
2008
The company is constructing a 50,000 tons/year thermal industrial phosphoric acid project and will recover the heat from the combustion of yellow phosphorus for steam production (10t/h);
2006
The company has implemented a separation of sewage and stormwater, and has established a surface water collection, treatment, and reuse system for the entire plant.
2001
The "Yunnan Province Industrial Waste Gas Purification and Carbon Chemical Research and Development Center" is established in the company;
1999
Provincial Institute and Provincial School Cooperation Project - 300 tons/year purification of yellow phosphorus tail gas to prepare dimethyl carbonate project implementation, successfully achieved in the purification and utilization of yellow phosphorus tail gas and obtained a patent;
1997
The company has passed the standard acceptance of the "Create a Leak-Free Chemical Plant" organized by the Provincial Chemical Industry Department.
1993
The company's "Phosphorus Slag Comprehensive Utilization Research Project" has achieved success, winning the third prize for scientific and technological progress in Yunnan Province, and in 1998, it received the honor of "National Environmental Protection Best Applicable Technology Supporting Unit" from the State Environmental Protection Administration.
1991
The company has independently designed and built a set of yellow phosphorus tail gas recovery device for ore drying.
