Increasing in the Recovery for Acrylonitrile Refining by Optimization of the neutralizing Tower Operation 优化中和塔操作提高丙烯腈精制回收率
The effect of new neutralizing corrosion inhibitors, SF-121B and BZH-1, for inhibiting carbon steel corrosion in H_2S-HCl-H_2O system on the top of atmospheric and vacuum distillation tower was studied. The result indicated that with the H_2S concentration increasing, the corrosion rate increased. 研究了新型中和缓蚀剂SF-121B和BZH-1在常减压蒸馏塔顶H2S-HCl-H2O腐蚀系统中的缓蚀效果,结果表明随着H2S浓度增加,腐蚀速率增加;
