ABSTRACT OF THE DISCLOSURE: This invention relates to a process for the iso- thermal absorption of the ethylene oxide contained in the gas from an ethylene oxide production plant. This process is characterised in that the gas is firstly cooled to a temperature of between 5 and 60°C, and is then fed at a pressure which can vary from 1 to 30 ata to a water-fed isothermal film absorber, from the bottom of which is ob- tained a high concentration ethylene oxide solution which can be fed directly to the glycol production plant after recovering the ethylene still in solution. By means of this process, the absorption plant is simplified compared with known processes, and steam, electricity and cooling water consumption are considerably reduced.
