In the conventional process to make MEG, ethylene oxide would be heated and fed to a reactor with water to ultimately produce the MEG. In the new process, however, the ethylene oxide flows into a reactor with carbon dioxide (CO2) and a clear syrupy liquid catalyst helps convert the mixture into ethylene carbonate.
The ethylene carbonate enters the second reactor where it reacts with water to produce MEG. The process converts 99.2% of the ethylene oxide in the process into MEG, compared to 90% in the conventional process. This eliminates the cost of storing and shipping any secondary products.
The new process consumes less steam and produces less waste water than a traditional plant with the same capacity. The OMEGA process also produces less CO2 per tonne of MEG.
