What is a TEG unit?
What is TEG in oil and gas?
TEG is used by the oil and gas industry to "dehydrate" natural gas. ... Triethylene glycol is heated to a high temperature and put through a condensing system, which removes the water as waste and reclaims the TEG for continuous reuse within the system.
What is the function of the gas dehydration unit?
Purpose. The purpose of a glycol dehydration unit is to remove water from natural gas and natural gas liquids. When produced from a reservoir, natural gas usually contains a large amount of water and is typically completely saturated or at the water dew point.
What is TEG package?
Gas dehydration packages with liquid media technology (TEG-DEG-MEG) is the process used by Pietro Fiorentini to remove water from natural gas and from its liquids (NGLs). ... The dry outlet gas specification obtained in TEG dehydration units is in the range of 3 to 7 lb water/MMSCF gas.
How does TEG absorb water?
To take the water out of natural gas, producers use a liquid called triethylene glycol, also known as TEG. When gas comes into contact with triethylene glycol, the water vapors entrained in the gas are absorbed in the TEG. In effect, the glycol "soaks up" the water.
What is the difference between Meg and TEG?
The key difference, however, is the circulating TEG system requires a high pressure contactor while the MEG injection system does not. In this situation, the most likely choice will be to go with the MEG Injection system.Mar 1, 2007
What is a dehydration unit?
A dehydration unit is used to remove water vapor from natural gas streams to meet an outlet pipeline specification, which is normally 7lb/MMSCF or less.
Which chemical is used in dehydration unit?
Triethylene Glycol (TEG)
Triethylene Glycol is most commonly used in glycol dehydration. It reconcentrates at temperatures between 350° and 400°F, which yields purity of 98.8%.
What is diethylene glycol used for?
Diethylene glycol (DEG) is a sweet-tasting, colorless, nonodoriferous, hygroscopic liquid commonly used in the commercial preparation of antifreeze, brake fluid, cigarettes, and some dyes. It is an excellent solvent for many relatively insoluble substances.
What is amine used for?
The most commonly used amines in industrial plants are the alkanolamines DEA, MEA, and MDEA. These amines are also used in many oil refineries to remove sour gases from liquid hydrocarbons such as liquified petroleum gas (LPG).

What is a dehydration column?
The dehydration column is in two sections: in the lower section, oil is pumped at a high flow rate to avoid formation of deposits and oil cracking by ensuring a good heat transfer. ... This column helps to eliminate variable amounts of water in the lower section and, finally, dehydrate the oil in the upper section.

How much power does a Teg produce?
- How critical is DT. The same 100 watt TEG above will produce: 200 watts: If DT is increased to 150°C. 350 watts: If DT is increased again to 200°C. Power output in relation to Per Degree Celsius expansion between the hot and cold side is roughly 1°C = 2 to 2.5 watts of output.
