Large-Scale Industrial Testing



The Curtin Corrosion Centre owns and operates the only Mono-Ethylene Glycol (MEG) laboratory scale regeneration and reclamation research facility in Australia. The system simulates a full industrial MEG regeneration loop from condensate/MEG separation, divalent cation removal through pre-treatment, regeneration by distillation and either full or slip-stream vacuum reclamation for dissolved salt removal. The system allows the simulation of any potential field fluid composition and operational condition, in order to study and improve industrial plant operation and diagnose operational issues occurring in the field.

MEG research

A wide range of testing can be facilitated including;

  • well clean-up studies,
  • corrosion studies,
  • scaling and fouling studies,
  • simulation of corrosion mitigation strategy switchover, and
  • analysis of production chemical behaviour.

In conjunction with laboratory testing, the behaviour of production chemicals within MEG systems can be studied including performance evaluation, analysis of degradation behaviour (during distillation/reclamation) and studying unforeseen effects on MEG process chemistry. Overall, the system can be utilised to reduce uncertainties associated with planned changes in operational methodologies, production chemical usage and the verification of laboratory testing on a larger scale.

Previous testing conducted using the Curtin MEG pilot plant includes simulation of corrosion mitigation strategies for Chevron’s Gorgon and Jansz MEG and natural gas systems. Studies were undertaken to identify unforeseen operational concerns that would arise during the transition from film-forming corrosion inhibitors to pH stabilisation and vice versa before such operations were conducted live in the field. Extensive testing has also been carried out to evaluate various aspects of Chevron’s MEG regeneration system production chemistry including testing of corrosion and scale inhibitors, oxygen scavengers, system-wide pH management and the optimisation of contaminant removal processes.
