The design aims at the production of 600 tons of sodium lauryl polyoxyethene (7) isooctyl sulfosuccinate. Using maleic anhydride and hydroxyl compounds to esterification, then ester and sodium sulfite addition, Process design for the whole production workshop. In this paper, the design of the requirements focuses on the design, to select a reasonable process. The material balance and heat balance of the whole process were carried out, and the parameters of the reactor were determined. It has completed the equipment calculation and selection of the whole workshop, the layout design of the workshop. This design follows the spirit of the theory with practice and draws a process flow diagram, equipment layout, material balance chart etc. According to the properties of raw materials and products, and puts forward the method of safety production, waste treatment methods and safety precautions.
The scale of this design is 600 tons of sodium lauryl polyoxyethene (7) isooctyl sulfosuccinate, started in 300 days, two operating system, each batch yield is 1000kg. It has the material balance, heat balance and equipment selection calculation. It also explains the environmental protection measures and the safety production standard.
Guiding by the tutor 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 sodium lauryl polyoxyethene (7) isooctylsulfosuccinate process, and my knowledge and experience is limited. So having design errors and anything wrong with that, I urge marking teacher criticism.
