It has been found out that the major culprits for the corrosion cracking are the concentration of harmful ions from causticwash and material settlement and residue tension strain.
装置碱洗、物料沉积导致有害离子浓缩及设备存在残余拉应力是造成腐蚀开裂的主要原因。

Optimization of causticwash process, strengthened monitoring of critical equipment or application of duplex stainless steel or super stainless steel can mitigate the cracking problems.
优化碱洗工艺、对重点设备加强监测或采用双相不锈钢及超级不锈钢可使腐蚀问题得到缓解。

The main production facilities are mixing device, reactor, air cooler, water scrubber, causticwash tower, compressing machine, condensate cooler, dissociator and distillating column and so on.
