Natural gas glycol gas dehydration for natural gas processing
Application:
The natural gas gylcol gas dehydration unit is applied for natural gas water removing.
Features:
The natural gas glycol dehydration unit has the below features.
The Glycol dehydration process is simple, mature technology, compared with other dehydration method can obtain a larger dew point drop.Good thermal stability.It is easy to regenerate and has the advantages of small loss, low investment and operation cost.
A lean/rich liquid heat exchanger is installed before the lean liquid circulating pump, which not only improves the operating conditions of the circulating pump, but also increases the temperature of TEG rich liquid into the triethylene glycol regenerator, effectively recovering part of the heat and reducing the consumption of fuel gas for regeneration.
Set a filter on the rich liquid channel to remove the mechanical impurities and degradation products carried in the solution system, keep the solution clean and prevent the solution from foaming, which can reduce the loss of the solvent and is conducive to the long-term stable operation of the device.
The direct fire tube heating method adopted in TEG regeneration is mature, reliable and easy to operate.
