Abstract: An amount of water is added to a glycol solution to be purified to enable segregation of the resulting mixture into a hydrocarbon phase and a glycol phase. The hydrocarbon phase is separated from the glycol phase and said glycol phase is desalted, e.g. by electrodialysis, to give a desalted and substantially hydrocarbon-free glycol solution which is then concentrated by steam stripping. The method is useful for purifying waste glycol solutions resulting from oil or gas production effluent processing using glycols, and in particular from a gas hydrate inhibition treatment or natural gas dehydration.

Abstract: The in vivo oxidation of lipids and lipid-containing molecules has been discovered to be initiated by the concurrent reaction of such lipid materials with reducing sugars such as glucose, advanced glycosylation endproducts such as AGE-peptides, or a compound which forms advanced glycosylation endproducts, to form materials or particles known as AGE-lipids. AGE-lipids have been implicated in the aging process, the abnormal formation of lipofuscin and in various disease states such as diabetes and atherosclerosis. Diagnostic methods are contemplated, extending in utility from the detection of the onset and course of conditions in which variations in lipid oxidation, AGE-lipid levels, LDL levels, apolipoprotein levels, apolipoprotein receptor binding the like, may be measured, to drug discovery assays.
