NATURAL GAS DEMISTERS & DRYERS

Generality:

Natural gas (CNG) distributed in the piping lines contains water vapours.
An important requirement of compressed natural gas fuel is a low water dew-point. If water dew-point at delivery conditions exceeds the lowest ambient temperature a gas dryer shall be installed.
The selection of the dryer is in part determined by Client requirements and operating conditions.
To achieve very low water dew-point for a wide range of operating pressures it’s recommended to use a TPI heat regenerated natural gas dryer.
This type of dryer performs the adsorbing bed regeneration without gas consumption.
The regeneration gas (5% of the inlet flow) is withdrawn from storage at high pressure and then recovered in the drying circuit.
TPI dryers are fully pre-assembled and equipped with all necessary items for control and monitoring.
Each unit can be customized to Client requirements (according to Client specifications and environmental conditions).

System features Closed circuit regeneration without gas consumption Fully automatic control logic with system monitoring Self-supporting baseplate Easy maintenance & operation High reliability & flexibility Special exec. for very low ambient temperatures Ready for operation Natural gas dryer front view
