I am looking for some data on a phenomenon that occurs in carbon dioxide dehydration. At certain combinations of temperature and pressure the glycol becomes very ineffective in its capacity to absorb water. I am talking about temps within the safe range of reconcentration, not above the degradation temp. I think I heard mention something about Shell had done some work on this?? Can anyone give me any insight/articles/tech papers on this??
Thanks
