MEG regeneration/reclamation

The centre has built the only MEG regeneration and reclamation laboratory scale research facility in Australia with a capacity of 4 litre per hour of lean-MEG production. The facility can operate in slip stream mode or full reclamation mode. It is possible to simulate virtually any rich MEG composition (water and dissolved salt) and condensate blend to enter the MEG pre-treatment vessel, simulating condensate carry over from the high pressure 3 phase separator. The facility is designed to study and improve plant operation (salt removal, minimising MEG losses, in-situ cleaning), influence of MEG production chemical additives on the MEG regeneration/reclamation process, validation of chemical qualification results etc.).

In addition, corrosion studies can be performed at any section of the facility, including simulating TLC and BLC using different feed compositions have been initiated. Current research activities include clean-up to host studies (the fate of drilling mud entering the MEG facility), changeover studies from different corrosion mitigation strategies and the effectiveness of oxygen scavengers in MEG system. Last but not least, MEG and the production additives are subjected to thermal cycles in the regeneration and reclamation process, which may result in degradation. CCEIC has developed analytical methods to study MEG degradation products, corrosion inhibitor concentration, as well as organic acid concentrations and dissolved salts in the fluids.
