    Pre installed semi-automatic dehydration device for CNG refueling station

    The semi-automatic equipment only requires the operator to manually switch the valves on site when switching between the two towers, and the regeneration process is automatically controlled. The equipment will release a small amount of natural gas when switching between two towers.
    This series of products is suitable for gas stations with small investments and dedicated personnel for operation and maintenance.

    Product Detail

    Process description:

    The blue line in the figure represents the adsorption circuit, the red line represents the regeneration circuit, and the gray line represents the discharge circuit. The wet gas enters the pre filter from the intake port, removes free oil, water, and dust, and then enters tank A through reading 3. After dehydration, the gas passes through valve 5 and the post filter to remove adsorbent dust before being sent to the outlet. The regeneration circuit is shown in the figure. The gas is pressurized by the circulating fan and enters the heater. After heating up, it enters the desorption bed of tank B through valve 8, and then enters the cooler through valve 2. After cooling, it enters the separator to remove the liquid water precipitated in the gas, and then re enters the circulating fan for pressurization.
