Overview：

Using a small-scale scroll compressor as the circulation power source, conducting isobaric closed-loop heating regeneration without the need to release pressure inside the tower, saving resources and protecting the environment, reducing the gas loss of CNG refueling stations, and truly achieving zero emissions. There is no significant pressure change during the regeneration switch, which minimizes the impact on valves and molecular sieves.

process flow

1、The porous molecular sieve solid adsorbent is used to remove water from natural gas, so as to purify gas and reduce water dew point;

2、 The equipment is composed of molecular sieve absorption tower, pre coalescence filter separator, post dust removal filter, heat exchanger, regeneration gas air cooler, regeneration gas-liquid separator, automatic switching valve group and other components;

3、 Natural gas enters from the top of the dehydration tower and completes the Adsorption Dehydration Process in the molecular sieve dehydration tower from top to bottom;

4、 After a certain period of time, the dry gas heated to 300 ℃ is used to purge the molecular sieve bed from bottom to top. The water adsorbed by the molecular sieve is desorbed by high temperature heating, and the molecular sieve is regenerated.

Features and Advantages

Features

1. Efficient Drying:

   Front natural gas dryers efficiently remove moisture from natural gas by cooling the gas below its dew point, preventing freezing or condensation under low temperature or high pressure conditions.

2. Variety of Drying Technologies:

  They utilize various drying technologies such as cooling, adsorption (using molecular sieves, silica gel, etc.), or chemical drying (using desiccants) to meet different application needs.

3. Automatic Control System:

  Many modern dryers are equipped with automatic control systems that monitor and adjust operating conditions such as temperature, pressure, and desiccant status in real-time, ensuring consistent and stable drying performance.

4. High Corrosion Resistance:

  Designed with corrosion-resistant materials, these dryers handle natural gas containing corrosive components, thereby extending equipment lifespan.

5. Versatile Adaptability:

  The design accommodates various natural gas flow rates and pressure requirements, making it suitable for different scales and types of natural gas processing facilities.
