An analysis is made of the feasibility of the recovery of spent lye from final purification for use in the desulfurization section, and a description is given of the measures of technical renovation. 分析了精炼废碱液回收至脱硫岗位应用的可行性,叙述了技术改造措施。
In Qilu's Ethylene Plant, sodium sulfide in spent lye is slowly oxidized by air to produce soluble sulfate which is discharged to spent water disposal system. 采用空气缓慢氧化处理乙烯装置废碱液中的硫化钠,使之生成可溶性的硫酸盐,从而可排入污水处理系统处理。
