Triethylene glycol TEG natural gas dehydration for natural gas processing
Application:
The TEG natural gas dehydration is applied for natural gas water removing.
Description:
The TEG natural gas dehydration adopts about 99.74% (wt) triethylene glycol (TEG dehydrating agent, removing the most saturated water in wet natural gas purification, purification by TEG absorber after dehydration dry gas (in the factory water dew point pressure condition < - 5 c) as a commodity to outside gas pipeline.
After water absorption, TEG is regenerated by the method of atmospheric pressure fire tube heating and regeneration.
After heat exchange, the heat-depleted liquid is cooled and returned to the TEG absorption tower after pressurization for recycling.
The gas-forming components produced by the regeneration of the rich liquid are mainly water vapor and contain a small amount of hydrocarbons and gases.
In order to eliminate potential safety hazards and avoid direct emissions of environmental pollution, the recycled waste gas from the sulfur recovery device is discharged into the atmosphere after burning in the exhaust gas burning furnace.
