【Abstract】 The cost of PVC resin produced by calcium carbide process in Zhongfa Co.of Shihezi is analyzed,and following methods are adopted to reduce the cost:(1)strengthening the management of purchasing calcium carbide to reduce the defective percentage to less than 20%,and thus reduce the consumption of calcium carbide;(2)controlling the purity of hydrogen chloride ≥93%;(3)expanding production capacity (from 8 000 t/a to 25 000 t/a).So the cost of PVC resin can reduce from 5 419 RMB $/t to 3 955 RBM $/t.更多还原
