Abstract
This invention relates to a process for the isothermal absorption of the ethylene oxide contained in the gas from an ethylene oxide production plant. This process is characterized in that the gas is firstly cooled to a temperature of between 5.degree. and 60.degree. C., and is then fed at a pressure which can vary from 1 to 30 atm. to a water-fed isothermal film absorber, from the bottom of which is obtained a high concentration ethylene oxide solution which can be fed directly to a glycol production plant after recovering the ethylene still in solution. By using this process, the absorption plant is simplified compared with known processes, and steam, electricity and cooling water consumption are considerably reduced.
