The formula for adsorbent filling in adsorption dryer:
According to the flow rate indicated on the nameplate of the suction dryer, about 25kg of alumina is consumed per 1L/min of flow rate, which is exactly one bag. For example: a 40 cubic suction dryer, the weight to be filled with alumina is: 40*25=1000 kg, that is, 40 bags of alumina;
Common options recommended based on differences in gas requirements (different pressure dew points):
1) If the customer only needs a pressure dew point of -40 degrees, all use 4-6MM XR101 activated alumina
2) If the customer requires a pressure dew point of -40--60 degrees, use half of 3-5MM XR101 activated alumina and half of 6-8MM actvated aluminaalumina
3) If the customer requires a pressure dew point of -70 degrees, use 2/3 4-6MM XR101 activated alumina and 1/3 4A molecular sieve
