中国是目前世界上最大的电石生产国和消费国,其产能过剩的局面存在已久。截至2015年底,中国电石产能达到3800万吨/年,供应量达到2584万吨,表观消费量达到2571.0万吨。随着国家过剩产能退出机制的出台,一些没有资源优势的企业逐渐被淘汰,电石产能新建和退出相互抵消,形成动态平衡。预计到2017年我国电石产能将达到4000万吨/年。电石需求的增长主要受下游PVC消费增长的拉动,但由于中国房地
China is currently the largest producer and consumer of calcium carbide in the world, and its overcapacity situation has existed for a long time. As of the end of 2015, China’s calcium carbide production capacity reached 38 million tons / year, supply reached 25.84 million tons, apparent consumption reached 25.7 million tons. With the introduction of the national mechanism for the withdrawal of excess capacity, some enterprises without any resource advantage have gradually been eliminated, and new and withdrawn capacity of calcium carbide production has offset each other to form a dynamic equilibrium. It is expected that by 2017 China’s calcium carbide production capacity will reach 40 million tons / year. The growth of demand for calcium carbide is mainly driven by the growth of downstream PVC consumption, but due to China premises
