Benefits of Installing a MEG Recovery Unit

Strong increase in demand for natural gas leads to more development of deep offshore gas deposits with deeper wells, longer subsea pipelines, higher pressures and lower temperatures. Under such conditions, hydrate formation – that blocks flow lines and can cause plant shutdowns – is a major risk so effective hydrate inhibition is key.

Injection of large volumes of Monoethylene Glycol (MEG) at the wellhead is an effective way to prevent hydrate formation and assure gas flow. MEG returns to shore in a mix of gas, hydrocarbons, water, salts and other solids; replacement is very costly and the installation of MEG

  • Regeneration and Reclaiming system provides the following benefits
  • Significant reduction in purchased volume of new glycols,
  • Greater protection against hydrate formation and pipeline freeze-up because of higher glycol and lower water content,
  • Significantly lower corrosion of sub-sea and onshore flowlines,
  • Significantly reduced fouling and scaling,
  • Smaller circulating volumes in glycol loop because of reduced water, salt and other injected chemicals.

Industrial References
The MEG Regeneration and Reclaiming Technology developed by CCR Technologies Ltd. is a pioneer technology with the first commercial operation in the world of a MEG reclaiming unit being started-up in1999 for Shell Mensa Offshore Project in the Gulf of Mexico.

As of today, twelve MEG Regeneration and Reclaiming Units have been licensed with this technology including the largest unit in the world for Wasit Gas Plant project in Saudi Arabia developed by Saudi Aramco (Rich MEG capacity = 4 x 66 m3/h).

Process Description

PROSERNAT is the exclusive licensor of the MEG Regeneration and Reclaiming proprietary process owned by CCR Technologies Ltd., a Canadian company having developed in the 90’s the most cost effective process to purify and reclaim high value chemicals.

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.

A typical MEG Regeneration and Reclaiming Unit comprises four functional sections:
