The natural gas just extracted from the well is usually filled with saturated water vapor, which can cause serious harm. Natural gas containing acidic components is prone to acid corrosion of pipelines and equipment in the presence of water; Moisture can reduce the transportation capacity of natural gas pipelines and cause unnecessary power consumption. Therefore, natural gas dehydration is very necessary. Natural gas dehydration is a process that uses certain methods to remove saturated water vapor from natural gas. Common methods include cooling dehydration, solvent absorption dehydration, solid adsorption dehydration, membrane dehydration, etc. Different dehydration methods have their own characteristics and are suitable for different environments. The main process of triethylene glycol is as followed: Wet natural gas in saturated state is separated by the filter separator to separate the liquid drops of 5 μ m and above, and then enters the gas-liquid separation chamber at the lower part of triethylene glycol absorption tower of dehydration unit to separate the free liquid that may be brought into the absorption tower when the filter separator is in accident state. Enter the absorption section through the riser of absorption tower. The regenerated triethylene glycol is pumped into the top of the absorption tower to fully contact with the natural gas from the bottom up on the absorption tower for mass transfer and moisture removal. The dehydrated natural gas is discharged from the tower after removing more than 5 μ m glycol droplets through the tower top mist catcher. After leaving the tower, the heat is exchanged with the hot lean glycol before entering the tower through the tubular heat exchanger to reduce the temperature of the triethylene glycol entering the tower. After heat exchange, the natural gas enters the filter separator to separate out the carrying glycol and then enters the export pipeline. The rich triethylene glycol (TEG), which absorbs the moisture in natural gas, flows out of the absorption tower and enters the liquid level control valve. After depressurization, it enters the reflux cooling plate on the top of the rich liquid distillation column to exchange heat with the hot steam generated in the reboiler. After providing the reflux cooling capacity of the column top, the rich triethylene glycol is heated to about 50 ℃. The outlet tube enters the TEG flash tank. Rich glycol is depressurized to 0.4MPa ~ 0.6MPa in flash tank. Hydrocarbon gas and other gases dissolved in TEG are flashed out, and these gases are used as fuel gas for reboiler combustion.
