Abstract: 1,170,193. Ethylene oxide. SNAM PROGETTI S.p.A. 12 Feb., 1968 [17 Feb., 1967], No. 6884/68. Heading C2C. Ethylene oxide is produced in a continuous process by catalytically oxidizing ethylene with air at elevated temperature, separating all or substantially all of the ethylene oxide from the resulting discharge gases which contain unreacted ethylene, subjecting at least a portion of the remaining discharge gases to combustion in a combustion chamber at controlled temperature and pressure, whereby the pressure of the remaining discharge gases is increased, and allowing them to expand in an expansion turbine connected to a compressor whereby compressed air for use in the catalytic oxidation of the ethylene is produced. If desired the remaining discharge gases referred to may be preheated before entering the combustion chamber by utilizing the heat of the gases leaving the turbine. After the separation of the ethylene oxide from the discharge gases part of the remaining discharge gases may be recycled to the catalyst.
