Adsorbents such as molecular sieve have the characteristics of selective adsorption of adsorbents (H2O, H2S), especially molecular sieve dehydration, dehydration index can reach the purification requirement of 0.1ppm, molecular sieve dehydration device is an indispensable process unit for cryogenic pretreatment. At the same time, molecular sieve dehydration is also used for CNG recovery and external gas transmission dehydration by adjusting the process flow and operating parameters. For molecular sieve dehydration devices with a treatment capacity of less than 10 × 104Nm ³/h, skids can be integrated.
Molecular sieve dehydration unit mainly includes filter, drying tower, regeneration gas system and program control and other major equipment.
