Mechanical vapor recompression for PureMEG system

The MEG regeneration and reclamation system often demands the largest heating duty in a gas facility. Efficiency improvements in heat integration can significantly affect facility opex for heating and capex for the heating medium system.

Our advanced heat integration process uses mechanical vapor recompression (MVR) to transform waste heat from the MEG regeneration overheads into a usable heating medium for the process.

Carbon reduction and lower opex

The MVR compressor boosts overhead vapor—a low-grade steam—from the MEG regeneration column to a usable low-pressure steam, reducing heating energy demand by 75%, which in turn decreases opex and greenhouse gas (GHG) emissions. The compressor increases electrical demand slightly, <10% of heat duty, with the actual usage engineered for maximum savings for a specific facility.

Both slipstream and full-stream MEG regeneration and reclamation systems can benefit. Other industries have proved that the concept can improve process economics and sustainability.
