Abstract
A lean MEG stream having a first pH level is contacted with a CO2-rich gas stream to yield a lean MEG product having a second different and lower pH level preferably in a range of 6.5 to 7.0. The system and method can be readily incorporated into a slipstream MEG recovery package, with a source of the lean MEG stream being a MEG regeneration section of the package. The CO-rich gas could be a vented COstream from the MEG reclamation section of the package. Unlike hydrochloric and acetic acid overdosing, COoverdosing of the lean MEG stream does not lead to rapid acidification of the lean MEG product to be stored or injected.
