*2.2.2 Influences of gas contact temperature on water dew point*

To determine the effect of the gas contact temperature, the given feed gas is taken into account and the temperature is varied. The water dew point of the gas will be calculated for each option (**Figure 3**).

The graph shows that as the gas contact temperature decreases, the amount of water contained in the gas after drying also decreases. This is due to the fact that low temperatures increase the capacity of absorbents, allowing them to absorb more water contained in the gas; therefore, the lower the gas temperature, the lower its equilibrium moisture capacity and then low water dew point. In addition, high temperatures increase TEG losses. The lower the process temperature, the lower the calculated concentration of glycol is used to obtain the target gas dew point. A decrease in temperature also leads to the destruction of the heat consumption for the operation of the regeneration unit, since the amount of water extracted from the gas decreases.

#### *2.2.3 Effects of the stripping gas on TEG regeneration*

After drying the gas, it is necessary to check the flows to determine at what temperature the gas will be hydrated.
