Complete a Level 0 through Level 3 Conceptual Design and an associated process flow simulation for a commercial-scale process to produce ethylene oxide. The question is to identify the reactor operating window for the Level 3 Design directly on the flammability/explosive limits diagram given in the EO Project Basis. Qualitatively characterize the explosion risk as high, moderate, low, or negligible. I need to write an introduction about the flammability and explosion of ethylene oxide in the presence of pure oxygen and answer the question above. I have attached a photo of the (flammability/explosive limits diagram given ). Here are some helpful sources:
