摘要
介绍了浓硫酸清净乙炔工艺的原理及流程,并与原次氯酸钠清净工艺进行了比较。采用浓硫酸清净乙炔工艺可使发生系统用水达到平衡,按10万t/a PVC计,可获经济效益156.5万元/a。
The theory and flow path of the purification process of acetylene with concentrated sulphuric acid were introduced, and compared with that of the original purification process of acetylene with sodium hypochlorite. The purification process of acetylene with concentrated sulphuric acid could realize the balance of water consumption in the acetylene kt/a PVC facilities as examples, 1. 565 million RMB ￥ economic year production system. Taking 100 benefits could be achieved per
