摘　　要：针对目前煤/甲醇制烯烃装置中浓缩水乳化严重的问题,开发了一种物理破乳除油技术——Fiber Mem TM纤维膜油水分离技术。介绍了该技术的原理以及在中煤蒙大DMTO装置上进行的1 t/h浓缩水破乳除油工业性试验的情况。工业试验表明,采用该技术可实现浓缩水的破乳和油水分离,浓缩水出水清澈;试验装置运行稳定,系统抗污堵能力强;处理后的浓缩水,可直接进入MTO反应器回炼,实现多产乙烯、丙烯产品的目的。To solve the problem of the serious concentrated water emulsion in the coal/methanol to olefin project,a novel physical de-emulsion and de-oil technology-Fiber MemTM fibrous membrane oil water separation technology was developed.The principle of the technology was introduced,and an industrial experiment of 1 t/h concentrated water de-emulsion and de-oil was carried out in DMTO unit of China Coal Mengda.The results showed that this technology could achieve high accuracy de-emulsion concentrated water and oil-water separation,with clear water coming out.The test unit ran stably and the system had strong anti-plugging capability.After de-emulsion,the concentrated water could be recycled directly into the MTO reactor and increased the yield of ethylene and propylene.
