The scale of the design for the sodium polyacrylate is1000 tons per year，according to 330 days a year，2 shift a day, 8 working hours a shift, they can produce two batches in a shift, the yield of each batch is 773.04kg. Then mentioned safety production standardization and the measure of environmental protection.
Professor XuChunHua, guiding by the director originally, had submitted a lot of valuable and positive suggestions, had helped me to raise the design mass. Here, I express my sincere thanks to them. Throughout the design process, I had a comprehensive understanding of their production process. According to my professional knowledge, combined with the learning experience, flexible application, laid a basis for future work related.
Because of the wide range of knowledge of the design of Polyacrylate sodium process, and my knowledge and experience is limited. So having design errors and anything wrong with that, I urge marking teacher criticism.
