New Record of Resin Calcium Carbide Unit Consumption in Shaanxi Beiyuan

In view of the current market environment of sustained macroeconomic decline and persistent depressed price of polyvinyl chloride, Shaanxi Beiyuan Chemical Company continuously strengthens internal control management, benefits to production units, benefits to management, and continuously promotes energy saving, cost reduction and efficiency enhancement, and has achieved remarkable results. Since August this year, the consumption per unit of resin has dropped from 1.35 tons to 1.33 tons, which has set a new record.

Since July 2015, Beiyuan Chemical Company of Shaanxi Province has analyzed and summarized the factors affecting the consumption of calcium carbide, and adopted a series of measures to reduce the consumption of calcium carbide: first, to strictly check the storage of calcium carbide and eliminate the adulteration of calcium carbide; second, to strictly control the stock of calcium carbide within 30 tons to reduce the weathering of calcium carbide; third, to supervise the sampling process and improve the accuracy of inspection; and fourth, to add a series of measures. Strong generator operation management, optimize generator operation index and slag discharge operation, improve generator operation cycle; Fifth, optimize the operation of polymerization unit, carefully control process index, reduce waste production; Sixth, according to the converter containing acetylene, hydrogen chloride index, every two hours to adjust the converter air intake, reduce acetylene waste. Through the above measures, the unit consumption of calcium carbide decreased to 1.33 tons from August to October.

Calcium carbide as a bulk raw material, the cost accounts for more than 60% of the production cost of PVC. According to the current production load statistics, the unit consumption is reduced by 0.01 tons, which can save the company 15-160,000 yuan per month. According to this conversion, only calcium carbide unit consumption saves about 770,000 yuan from August to October.
