Molecular sieve manufacturer tells you some measures to prevent molecular sieve deactivation
How to prevent the deactivation of molecular sieves? Today, molecular sieve manufacturer
s will tell you about these measures!
1. Enhanced drainage: When the adsorbent concentration exceeds the standard, it will cause permeation before adsorption, but will not completely deactivate the molecular sieve. It can be reactivated through regeneration. Drainage should be strengthened during operation to minimize water entering the molecular sieve, especially in humid conditions. In rainy days, the cooling humidity of compressors at all levels should be controlled so that water vapor becomes water and discharged. As for the content of hydrocarbons in the atmosphere, it is beyond human control.
2. Correct switching of molecular sieve: The switching of molecular sieve is the main factor that causes the mechanical strength of molecular sieve to decrease and pulverization. Therefore, it is necessary to operate correctly when switching, increase or decrease the pressure slowly, and do not increase or decrease the pressure too fast to avoid damage to the molecular sieve.
3. Prevent moisture intrusion: This measure is mainly for air separation devices that use steam heaters. The heater should be checked regularly, and the moisture in the regeneration gas should be analyzed regularly with a moisture analyzer. When overhauled every year, check whether the heater is decompressed , To ensure that the equipment is in good condition and prevent leakage.
4. Strengthen air filtration: Impurities are one of the main reasons for molecular sieve deactivation, which will cause great harm to molecular sieve and make it completely inactivated. 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 keep the air clean. At the same time, adequate filtering equipment should be installed and cleaned regularly before the air enters the compressor.
