Molecular sieve has wide application in many fields due to its unique pore structure and selective adsorption properties.

Air separation and oxygen production and nitrogen production

Molecular sieve separates oxygen and nitrogen in the air through pressure swing adsorption (PSA) technology, and is widely used in medical oxygen supply, chemical production, metal heat treatment and other scenarios. For example, 3A molecular sieve is used for nitrogen production, and 4A and 13X molecular sieve is used for oxygen production or deep drying of air.

Petrochemical raw materials drying

During petroleum refining, molecular sieve is used to dehydrate and dry raw materials such as ethylene, propylene, and cracking gas to prevent catalyst poisoning or pipeline corrosion. Its efficient adsorption performance can ensure the purity of raw materials and extend the service life of the equipment.

Natural gas purification and dehydration

Molecular sieve is used for dehydration treatment in natural gas fields to prevent hydrates from forming blockage of pipelines. At the same time, it can remove impurities such as sulfides and carbon dioxide in natural gas, improve the quality of gas, and comply with industrial and civil standards.

Refrigerant drying

In refrigeration systems such as automobile air conditioners and refrigerators, molecular sieves adsorb moisture in the refrigerant to prevent ice blockage and corrosion. For example, X-type molecular sieve is often used for deep drying of environmentally friendly refrigerants such as R-134a.

Industrial waste gas treatment

Molecular sieve is used as an adsorbent or catalyst carrier to treat waste gases such as volatile organic matter (VOCs), nitrogen oxides, etc. For example, catalytic oxidation reactions convert harmful gases into harmless substances to achieve standard emissions.
