What is a TEG contactor?

Triethylene glycol (TEG) is the typical choice in an absorption vessel to remove water. FLEXIPAC® HC® structured packing is typically recommended to increase the capacity of existing trayed towers. The use of structured packing also offers reduced column diameters and vessel height to process a given gas rate.

What is TEG package?

Triethylene Glycol (TEG), Diethylene Glycol (DEG) and Monoethylene Glycol (MEG) are used as liquid desiccants, but TEG is the most common for natural gas dehydration because of its stability and because its choice minimizes glycol losses.

How is TEG calculated?

The TEG Circulation rate calculation

  1. Use the Water Vapor Content of Gas Chart to Identify your water content (w).
  2. Multiply your water content (w) by the gas flow rate (m).

What is glycol operation?

The glycol dehydration process is an example of a process that provides absorption dehydration, and in the process, a liquid desiccant provides the means to absorb water from the gas stream.

What is a TEG unit?

Triethylene glycol (TEG) dehydration systems are commonly used for the removal of water vapor from natural and process gas. Water removal from natural gas is done to prevent hydrate formation and corrosion in downstream pipelines and process equipment.

What is a TEG pump?

Triethylene Glycol (TEG) Dehydration units remove water vapor from natural gas streams. Dehydrating gas prevents hydrate formation and reduces corrosion in pipeline transmission and gas injection applications. TEG acts as a desiccant to absorb water vapor from the natural gas stream.

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.

What is lean TEG?

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.

What is glycol regeneration system?

After leaving the flash vessel, the rich glycol is heated in a cross-exchanger and fed to the stripper (also known as a regenerator). The glycol stripper consists of a column, an overhead condenser, and a reboiler. The glycol is thermally regenerated to remove excess water and regain the high glycol purity.
