Optimization of caustic wash 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。
Presently, there've been no new breakthroughs in comprehensive utilization of the waste caustic liquid from ethylene cracking both domestically and internationally. 目前,国内外在乙烯裂解废碱液综合利用方面尚无新的突破。
Study on regeneration for spent caustic of ethylene cracking by chemical precipitation 化学沉淀法再生乙烯裂解废碱液的研究
The results showed that the corrosion weight loss rate of high Mn steel was distinctly greater than that of medium carbon chromium steel. The high Mn steel caustic embrittlement cracking was distinct in corrosion. 结果表明,高锰钢的平均腐蚀速率显著高于中碳铬合金钢,腐蚀过程中高锰钢有较严重的碱脆开裂现象。
With an increase of the chromium content in the cast steel, active dissolving corrosion increased, however, tendency of caustic embrittlement cracking decreased. 随着钢中含铬量的增加,试验材料的活性溶解腐蚀失重增大,但碱脆开裂的倾向减少。

An Investigation on Interface Reaction Regularity for Caustic Stress Corrosion Cracking of Fe-Cr-Ni Alloy Fe-Cr-Ni合金碱性应力腐蚀破裂界面反应规律的研究
Spent caustic liquid from ethylene cracking is the waste caustic liquid produced from the caustic scrubbing of cracking gas in ethylene plant. 乙烯裂解废碱液是乙烯装置在裂解气碱洗过程中产生的一股碱性废液。
With increasing corrosion time the impact toughness of high Mn steel obviously decreased. The major mechanism was effect of the caustic embrittlement cracking. 随着热强碱腐蚀时间的延长,高锰钢的冲击韧度明显降低,碱脆开裂是造成高锰钢冲击韧度下降的主要原因。
