Do molecular sieve need dry before using?

Molecular sieve is  commonly used for separation and purified gas mixture, which is usually used in the field of industry, chemistry and medicine. Although molecular sieves do not need to dry before use, drying may be necessary in some cases.

Dry molecular sieves can improve its separation and purification efficiency. When the molecular sieve is exposed to the air, it absorbs moisture, causing the pore diameter to increase, which makes the difficulty of separation mixture increase. Therefore, the drying of molecular sieve before use can improve its separation and purification efficiency and reduce unnecessary division of losses.

Dry molecular sieve can extend its life. In a humid environment, molecular sieves may be corroded and damaged, and in a dry state, molecular sieves can better maintain its structure and performance. Therefore, dry molecular screens can extend their service life.

However, it should be noted that even if the molecular sieve is in a dry state, it needs to be carefully operated to avoid damage to the molecular sieve due to improper humidity control. Therefore, in practical applications, proper tests and adjustments need to be performed before the use of dry molecular sieves, so that it maintains good performance and separation effect during use.

Although molecular sieves do not need to dry before use, in some cases, drying may be necessary, which can improve its separation and purification efficiency and extend the service life. Therefore, appropriate testing and adjustment should be performed when using molecular sieves to ensure its good performance and effect.
