For the effective inhibition of hydrate formation and corrosion in natural gas transmission and treatment systems, injection of Mono-Ethylene Glycol (MEG) or Methanol is commonly used. Methanol can be used in low temperature and high pressure but due to MEG’s lower viscosity and lower residue in liquid hydrocarbons, it uses commonly. MEG must be recycled, for reducing the costs and preventing environmental problems in process systems. The MEG that returns from the well is termed Rich MEG and contains significant quantities of water, dissolved salts and other contaminants. An associated recovery and regeneration process allow the MEG to be recycled. This called MEG Regeneration or Reclamation based on the kind of process.
Doran Energy is the exclusive representative of the MEG Regeneration and Reclaiming proprietary process owned by PROSERNAT in Iran. The technology, based on patented and proprietary vacuum distillation and purification process, removes glycol contaminants with very high MEG recovery efficiency while minimizing waste effluents
