Glycol dehydration is a liquid desiccant system for the removal of water from natural gas and natural gas liquids (NGL). It is the most common and economical means of water removal from these streams. [1] Glycols typically seen in industry include triethylene glycol (TEG), diethylene glycol (DEG), ethylene glycol (MEG), and tetraethylene glycol ...

2019年11月5日 · Dehydration using triethylene glycol (TEG) is widely used in natural gas processing to avoid corrosion and plugging of the flow lines.

2021年4月29日 · A triethylene glycol (TEG) gas dehydration system is a setup used to eliminate water vapor from newly recovered natural gas. This drying equipment utilizes liquid triethylene glycol as its dehydrating agent to pull out water from a stream of natural gas flowing over it.

2019年7月2日 · Dehydration using triethylene glycol (TEG) is widely used in natural gas processing to avoid corrosion and plugging of the flow lines.

2022年5月1日 · Isolating the dehydration system and automating TEG dispersion based on the gas water vapor content limits TEG loss to vapor, corrosion of gas handling equipment, and operational excursions. The solutions discussed are automatic variation of TEG circulation rates, use of an inert gas in TEG storage tanks, a simplified TEG usage monitoring ...

2025年3月17日 · The liquid desiccant most often utilized is triethylene glycol (TEG). During the dehydration process, TEG absorbs water along with methane, volatile organic compounds (VOCs), and hazardous air pollutants (HAPs) when contacted with the wet gas.

The absorption of water using TEG is the standard method for natural gas dehydration. The use of TEG has advantages compared to the other glycols that it has lower vapor pressure and lower viscosity over its operating conditions. 3

Triethylene glycol and tetraethylene glycol are the most commonly used glycols for dehydration applications. Among these, triethylene glycol (TEG) has gained collective acceptance as the most effective glycol type because it is more easily regenerated [7].

2013年8月1日 · For dehydration of natural gas by triethylene glycol (TEG) process to a lower water content/water dew point temperature a higher lean TEG concentration is required. To achieve a higher lean TEG concentration at a specified reboiler temperature and pressure, commonly a stripping gas is used.

2019年11月1日 · Dehydration of natural gas by absorption using triethylene glycol (TEG) is a common industrial offshore procedure to ensure the compliance with the required water dew point specifications for midstream transportation.
