Product Details

Low pressure dehydration unit

CNG pre-dehydration unit refers to the equipment installed in front of the compressor, the raw material pressure is the incoming pipeline pressure of the product. It adopts the principle of temperature swing adsorption dehydration, uses the physical nature of the adsorbent to adsorb the saturated water in the raw natural gas in the incoming pipeline pressure state, and then uses the residual gas in the regeneration tower to carry out equal pressure, closed and zero emission analysis of the saturated adsorbent at a higher temperature. Adsorption and analysis are carried out in reverse.

■ The regeneration process is designed with zero emission, closed cycle and isobaric regeneration.

■ The circulating booster equipment has high pressure and good sealing, and will not leak easily.

■ External electric heater with high pressure is adopted to heat the regeneration bed evenly and facilitate maintenance. At the same time, multi-point temperature monitoring can prevent dry burning and ensure the regeneration effect.

■ All control parameters can be re-modified on the controller text display and have a fault diagnosis function.
