Teg degradation temperature
WebTEG has an initial theoretical decomposition temperature of 404F while the degradation temperature of diethylene glycol is only 328F The evaporation losses are lower for TEG than DEG. Simpler regeneration equipment is required. Dehydration operating and capital costs are lower than with DEG. WebS). This degradation results in the formation of organic acids, specifically, glycolic, formic and acetic acids. As degradation progresses and the pH of the fluid decreases, the …

WebThe three glycols (mono-, di- and triethylene glycol) discussed are composed solely of carbon, hydrogen and oxygen and have similar chemical properties. They have applications that vary mainly with physical properties such as viscosity, hygroscopicity and boiling point. 2. Structures The three glycols have the following structures and synonyms: WebNeal et al. (1989) describe a case in which loss from a TEG contactor was reduced from about 9 lb/MMscf to about 0.009 lb/MMscf by replacing a standard 4-in.-thick mesh pad made of 0.01 1-in.-diameter 304 stainless steel wire with a density of 9 lb/ft 3 by a 6-in.-thick pad containing fine multifilament dacron thread knitted in with the wire and …
