It was obtained mainly by the direct oxidation which ethylene and oxygen on the catalyst of silver. This industrial design was mainly about producing 60 thousand tons of ethylene oxide in the oxidation process. The basic properties of ethylene oxide and the use were described. According to the design plan requirements and the known design parameters, oxidation process was conducted including material and heat balance on the bases of the process of the ethylene oxide oxidation. At the same time, the reactor and the absorption tower were obtained by the calculations in chemical engineering technology; the main technology-related heat exchanger was selected; the oxidation process was carried out on the facade layout design; the reactor and the pipeline involved converters cooler pipes were done by piping design; the ethylene oxide oxidation involved piping and the instrumentation diagram (PID), facade layout map and local channel layout map were portrayed.
