The data analysis is consulted. In this process, PA6T salt is synthesized by intermittent polymerization, PA6T/66 prepolymer is synthesized by normal temperature aqueous solution polymerization, PA6T/66 resin is synthesized by high temperature and high pressure aqueous solution polymerization. The PA6T/66 resin is synthesized by solid-phase polycondensation. Select the best of raw materials, production equipment, polymerization method and separation method in the process flow. Carry out physical and heat balance to ensure the accuracy of data, select the equipment, draw the process flow chart, reactor profile and workshop layout. Based on the analysis of the actual situation, we shoud be established four production lines, each batch of which produced 7575.8kgpa6t/66 resin. The amount of raw materials added is 3321.98kg/batch of terephthalic acid, 2323.77kg/batch of hexanediamine, 5.65kg/batch of sodium hypophosphite, 1900kg/batch of water, 2577kg/batch of PA66 salt and 378.8kg/batch of antioxidant 1010. It is planned to produce one batch every day and work 330 days a year. Through equipment selection, Gsh-6000L made of stainless steel and carbon steel composite materials is obtained as the best equipment model. Frame impeller is selected as the a
