摘　　要：采用过渡金属氧化物沉淀法和苛化法处理乙烯裂解废碱液得到再生碱液,考察了再生碱液循环使用的可行性。结果表明:再生后乙烯废碱液的腐蚀性、结垢趋势以及发泡性能都在允许范围之内,同时循环再生试验结果表明其吸收性能可以满足裂解气碱洗的需要。The caustic was regenerated from the spent caustic in an ethylene plant which adopted precipitation with a oxide of transition metal and causticization.The feasibility of the regenerated caustic for recycling was studied.The results showed that the corrosion of the caustic,scaling on the equipment and the foaming performance all could meet the requirements for producing,the adsorption efficiency could meet the requirement of the regenerated caustic recycling for alkali wash.
