Abstract:
According to the present invention, there is provided means for suppressing the occurrence of corrosion on the inner tube side in a heat exchanger and enabling continuous production for a long time period in a process for producing ethylene oxide. An embodiment of the present invention relates to a method for producing ethylene oxide, the method including: supplying a raw material gas including ethylene, molecular oxygen, and a chlorine compound to an ethylene oxidation reactor; subjecting ethylene and molecular oxygen in the raw material gas to catalytic vapor phase oxidation in the ethylene oxidation reactor in the presence of a silver catalyst, and thereby producing a gas including ethylene oxide, water, and a chlorine compound; and cooling a gas to be cooled including water and the chlorine compound using a heat exchanger. According to this method, in the heat exchanger, the gas to be cooled including water to be cooled and a chlorine compound is cooled at a linear gas velocity on the heat exchanger inner tube side of 7 m/s or higher.

Claim (Index 2):
The production method according to  claim 1 , wherein\n in the heat exchanger, the temperature at the inlet of the heat exchanger inner tubes is higher than or equal to the dew point of water, and the gas to be cooled is cooled such that the temperature at the outlet of the heat exchanger inner tubes becomes lower than or equal to the dew point of water.
