What is UOP molecular sieve?

What is UOP molecular sieve?

UOP Molecular Sieves* are synthetically produced, crystalline metal aluminosilicates that have been activated for adsorption by removing their water of hydration. Unlike other adsorbents, Molecular Sieves have a precise uniform size and molecular dimension.

What is 3A molecular sieves?

BASF 3A Molecular Sieve is commonly used for drying of gases and polar liquids (methanol, ethanol) and easily polymerizable substances, such as unsaturated hydrocarbons (ethylene, propylene, acetylene and butadiene).

How do you use 3A molecular sieves?

Place the container of hot, regenerated sieves on the porcelain plate of a glass desicator and place under vacuum while they cool. Put dry sieves into bottles with polyethelene cap liners to keep dry until needed. Type 3A molecular sieves will reduce water in an air stream to 0.001 mg/liter air.

What are 4A molecular sieves used for?

Product Applications BASF 4A Molecular Sieve is commonly used for drying of organic liquids (solvents, oils, gasoline and other saturated hydrocarbons), air, liquid gases (propane, butane), as well as noble and other gases (H2, N2, He, Ar, etc.)

What does UOP stand for?

UOP

What is the difference between 3A and 4A molecular sieves?

3A is the preferred Molecular Sieves adsorbent for the commercial dehydration of unsaturated hydrocarbon streams. 4A is the preferred Molecular Sieves adsorbent for the static dehydration in a closed gas or liquid drying system.

What is 3A zeolite?

Molecular sieve is also know as a zeolite. A zeolite is a conformation of hydrated aluminosilicates of sodium, potassium, calcium, or other cations. Zeolites can be dehydrated and rehydrated, making them useful in drying applications.

Do you need to activate molecular sieves?

Molecular Sieve Activation: Molecular sieves must be activated (dried) before use. To check if molecular sieves are dry, you may put a bit in the palm of your hand and add a touch of water. If they generate a good amount of heat, they are dry.

What is 5A molecular sieve?

Molecular sieve 5A is a calcium form of alkali alumina silicate with an effective pore diameter of 5A°. It will adsorb all the molecules with a kinetic diameter of fewer than 5 angstroms and exclude higher than that. 5A will also adsorb a molecule that 3A and 4A will adsorb.

What is UOP standard?

Universal Oil Products (UOP) standards provide guidelines for oil and petroleum product testing and analysis. UOP standards primarily cover test methods for contaminants and make-up of oil, gas and materials used or generated in refining. Adhering to these standards permits you to: Simplify testing procedures.
