FIELD: chemistry.SUBSTANCE: claimed invention suggests method of ethylene oxide production, including: a. cracking ethane-containing initial material in cracking zone under conditions of cracking for obtaining olefins, including, at least, ethylene and hydrogen, b. conversion of initial oxygenate in zone of conversion of oxygenates into olefins (OTO) to obtain olefins, including, at least, ethylene; c. supply of, at least, part of ethylene, obtained at stage (a) and/or (b), into zone of ethylene oxidation together with initial oxygen-containing material, and oxidation of ethylene to obtain, at least, ethylene oxide and carbon dioxide; and in which, at least, part of initial oxygenate is obtained by supply of carbon dioxide, obtained at stage (c), and initial hydrogen-containing material, into zone for synthesis of oxygenates and synthesis of oxygenates, where initial hydrogen-containing material includes hydrogen, obtained at stage (a). In other aspect claimed invention suggests integrated system for ethylene oxide production.EFFECT: elaboration of process for obtaining ethylene oxide and optionally monoethylene oxide by integration of processes of cracking ethane and OTO, making it possible to reduce carbon dioxide emissions and quantity of synthesis-gas, required for synthesis of oxygenates.15 cl, 1 dwg, 6 tbl, 1 ex |
