Molecular sieve manufacturer talks about how to prevent molecular sieve deactivation

Molecular sieve deactivation should be prevented by corresponding measures. Then molecular sieve manufacturer will talk about how to prevent molecular sieve deactivation.

1. Strengthen drainage work: when the concentration of adsorbent exceeds the standard, it will cause pre-absorption permeation, but will not completely inactivate the molecular sieve, and it can resume activity through regeneration. During the operation, the drainage work should be strengthened to minimize the moisture entering the molecular sieve, especially in wet rainy days. It is also necessary to control the cooling humidity at all levels of the compressor to form and discharge water vapor. As for the content of hydrocarbons in the atmosphere, it is Uncontrollable.

2. Correctly switch molecular sieve: The switch of molecular sieve is the main factor that causes the mechanical strength of molecular sieve to decrease and pulverization. Therefore, when switching, it is necessary to operate correctly and slowly increase or decrease the pressure.

3. Prevent moisture intrusion: This measure is mainly for air separation units using steam heaters. The heaters should be checked regularly, and the moisture in the regenerated gas should be analyzed regularly with a moisture analyzer. When overhauled every year, the heaters should be decompressed and checked to ensure that the equipment is in good condition. To prevent leakage.

4. Strengthen air filtration: Impurities are one of the main reasons for molecular sieve deactivation, which is very harmful to molecular sieve and will completely deactivate molecular sieve. In order to reduce the pollution of impurities, the oil lubrication of the compressor cylinder can be eliminated on the one hand. On the other hand, it is necessary to strengthen the air management near the inlet of the air compressor to maintain air cleanliness. At the same time, adequate filtering equipment should be installed before the air enters the compressor, and regular cleaning should be carried out. Hunan Providence New Materials Co., Ltd is a professional molecular sieve manufacturer which can provide USY zeolite, NaY zeolite, REY zeolite, ZSM-5 zeolite, welcome to consult.
