摘　　要：对三效顺流、四体三效及三效四体3种生产质量分数42%等高浓度烧碱的蒸发工艺的优劣性进行了对比分析,认为四体三效工艺在隔膜法烧碱蒸发中具有较强的实用性。The production techniques of caustic soda with high concentration,such as 42%(wt.),are analyzed comparatively,including three kinds of process,three-effect downstream,four-evaporator three-effect and three-effect fourevaporator.It is considered that the four-evaporator three-effect process is the most practical for the evaporation of diaphragm caustic soda.
