Yellow Phosphorus Industry in Yunnan Upgrading

On the morning of October 12th, with a loud bang, the Yellow Phosphorus Production Plant of Yunnan Phosphorus Group Jinning Yellow Phosphorus Co., Ltd. with an annual capacity of 2,500 tons was demolished. At this point, Yunnan Province has dismantled seven yellow phosphorus production plants with an annual production capacity of 5,000 tons or less. At the same time, more than half of the production lines in the yellow phosphorus industry in the province have been transformed with new technologies. In Yunnan, the province with the largest production of yellow phosphorus in China, the industry’s efforts to support excellence and suppress inferiority have achieved remarkable results.
The production of yellow phosphorus has obvious problems of “three highs and one low” (high energy consumption, high consumption, high pollution, and low efficiency), and it is the industry that strictly controls the energy conservation and emission reduction of the country. Yunnan, which is the country's largest producer of yellow phosphorus, has 57 yellow phosphorous production enterprises. It has completed and put into production 147 production lines. Last year's yellow phosphorus production accounted for 51% of the country's total output. However, there are only four companies with yellow phosphorus production exceeding 10,000 tons in the province, accounting for only 7.7% of the total. Some enterprises unilaterally pursue quantity, resulting in the waste of phosphate resources and environmental pollution in the province.
To this end, since 2003, the Yunnan Provincial Party Committee and the provincial government have focused on restricting low-level redundant construction and eliminating small-yellow-phosphorus production facilities. They have made great efforts to promote the upgrading of the yellow phosphorus industry and create " Yunnan Yellow Phosphorus" brand. In that year, all yellow phosphorus production facilities with a capacity of less than 2,000 tons were eliminated. Subsequently, Yunnan Province issued and implemented the Interim Measures for the Administration of the Announcement of Yellow Phosphorus Production Devices in Yunnan Province, and in June last year further issued the Opinions on Promoting Structural Adjustment of the Yellow Phosphorus Industry and decided to dismantle below 5,000 tons before the end of this year. Device.
At the same time, the province strongly encourages enterprises to carry out technological transformation. Up to now, the province has 73 yellow phosphorus production lines using advanced three-phase six-pole technology, six sets of devices using triangular furnace technology, accounting for more than half of all production lines. The 5,000-ton or more devices all adopt intelligent electrode lift control systems, and the unit's comprehensive energy consumption is at a relatively advanced level in the country. At present, the utilization rates of phosphorus slag in some cities such as Kunming, Yuxi, and Qujing have reached 100%. Phosphorus recovery and reuse have been basically achieved in various yellow phosphorus production enterprises. The province has three fixed-point sludge recovery companies; yellow phosphorus All the waste water from the production enterprises achieve zero emissions.
It is reported that 43 small yellow phosphorus production plants will be eliminated by the Yunnan Provincial Government before the end of 2008, and 35 will be closed at the end of this year, and 8 will be closed in the first half of next year.
