Because of the epoxy group in the molecule, the curing agent is often added to make it undergo ring opening polymerization, so that it can be cross-linked from linear polymer to network polymer, which can be used as thermosetting resin. Therefore, epoxy resin is the basic chemical raw material. In this design, a one-step method is used to prepare epoxy resin. Bisphenol A (BPA) and epichlorohydrin (ECH) are polycondensated under the condition of sodium hydroxide. The ring opening and ring closing occur under the same reaction conditions to form diphenylpropane type epoxy resin. This paper introduces the workshop design of epoxy resin with an annual output of 2500 tons, and discusses the process, engineering economy and production management. The main contents are: design basis, process route, process flow, material balance of the whole process, energy balance of the whole process, process equipment, workshop layout design, treatment and utilization of three wastes, environmental protection and safety production, engineering economy and process details Improve the design.
