Compressed natural gas dryer CNG-DRY

CNG-DRY adsorption dryers are designed for continuous separation of water vapour from compressed natural gas thus lowering the dew point. CNG-DRY dryers are normally custom made to meet specific project requirements. Several versions are available based on operating pressure and type of regeneration. G-DRY type of the dryers are manual controlled and without regeneration. After the saturation of the dryer it is possible to replace adsorption material or regenerate it with external regeneration system. CNG-R-DRY has two columns that operate alternately. Adsorption takes place under pressure in the first column while the second column is heat regenerated. CNG-HP-DRY has also two columns that operate alternately. Regeneration is made by small portion of already dried CNG at the ambient pressure. Purge CNG is let to the suction side of the compressor.
