What is Required for Catalytic Cracking What is Cracking? Cracking refers to the chemical process of converting one sample (mainly high molecular compounds) into several other substances (mainly low molecular compounds) only by thermal energy. This is achieved by using high pressure and high temperature without a catalyst or by using lower temperature and pressure in the presence of a catalyst. Cracking can be categorized as catalytic cracking, thermal cracking, and steam cracking. In the process of petrochemical production, the cracking process employed higher temperatures (700 ℃ ~ 800 ℃, sometimes even up to 1000℃) to make the long-chain hydrocarbons…

Tellerette Ring-Your Cost-Effective Choice Tellerette packing ring is also called teller ring and tellerette rosette ring. It is well known for its economical and versatile performance characteristics because of its unique annular helix design. This design increases its surface area and the contact between the falling liquid and the rising vapor. And it is more efficient in mass transfer than traditional packing. has excellent heat transfer efficiency and mass transfer characteristics in gas absorption, air conditioning, etc. Tellerette Ring is widely used for high corrosion resistance and low pressure drop packing in gas absorbers, cooling towers, deaerators, and reaction gas-liquid…

Difference Between Silica Gel and Molecular Sieve? What is Silica Gel? Silica gel is a molecular sieve containing an irregular pattern of silicon and oxygen atoms with uneven pores. It is a form of silica and can be processed into various forms such as granules or beads. Silica gel contains nanoscale voids and pores. These voids may contain water or any other liquid that we use in the preparation of silica gel. For example, gas, vacuum, other solvents, etc. As the pore size is non-uniform, we can say that the average pore size of this molecular sieve is 2.4 nanometres.…

Know More About Mbbr Bio Filter Media What is MBBR Bio Filter media? By definition, MBBR means moving bed biofilm reactor, which is a moving media system for integrated fixed activated sludge (IFAS) and moving bed biofilm reaction (MBBR) systems, where MBBR media is the key to the system. In MBBR Bio Filter media, biofilms are protected and grown within engineered plastic media that have been carefully designed to have a high internal surface area. These biofilter media are suspended and thoroughly mixed throughout the aqueous phase. With this technology, it is possible to handle extremely high loading conditions without…

13x Molecular Sieve Regeneration Process What is Molecular Sieve Regeneration? Molecular sieve regeneration allows the wet or deactivated zeolite to restore to its original working capacity without damaging the zeolite or physical properties. It is a crucial step because it determines the performance and the overall operational cost of molecular sieves. Molecular sieve regeneration involves heating and purging with carrier gas to remove the adsorbate from the molecular sieve bed. To raise the temperature of the adsorbate, the adsorbent, and the container, adequate heat must be applied. Then the liquid can be vaporized to offset the heat from the surface…

About Oxygen Concentrators What Type of Zeolite is Used in Oxygen Concentrators? An oxygen concentrator is a device that concentrates oxygen from a gas supply (usually ambient air) by selectively removing nitrogen to provide a stream of oxygen-rich products. They were created to replace compact high-pressure oxygen cylinders or small cryogenic liquid oxygen systems, allowing patients using medical oxygen therapy to receive treatment at home. Oxygen concentrators consist of an air compressor, two cylinders filled with zeolite pellets or beads, a pressure equalization reservoir, and a number of valves and tubing. There are two main types of  provided by  on…

Introduction of Dixon Ring Packing What is Dixon Ring Packing? Tower packing generally refers to the material that is filled in other objects. In chemical engineering, Tower packing refers to the inert solid material packed in the filling tower, and in chemical products. Tower packing produced by Laiko, also known as filler, is a solid material used to improve processing properties, product mechanical properties, and reduce costs. is a kind of random filler for chemical processing. It is made of stainless steel woven wire mesh with a crossbeam, forming a ring with a central separator designed to be randomly filled…

What is a 5A Molecular Sieve? 5A molecular sieve is an alkali aluminosilicate in the calcium form of a Type A crystal structure with a pore size of 5 angstroms (0.5 nm). It can adsorb any molecule with a diameter smaller than 5 angstroms (0.5 nm). Not only does it have the functions of 3A, and 4A molecular sieves, but it also adsorbs C3-C4 n-alkanes, ethyl chloride, ethyl bromide, butanol, etc. Zeolite molecular sieve 5A can be applied to the separation of n-isomeric hydrocarbons, pressure swing adsorption (PSA) for gases, and the co-adsorption of water and carbon dioxide. Parameters of…

Types of Intalox Saddle The intalox packing used in industry column packing is also called intalox saddle. It is divided into ceramic, plastic, and metal intalox saddles according to the material. It has larger flux, lower pressure drop, and higher efficiency than raschig ring packing. The bed also has larger porosity. The advantages of both ring shape and saddle shape are combined in the intalox saddle and this kind of shape facilitates liquid distribution and increased gas passage. Plastic Intalox Saddle A plastic intalox saddle is also called a plastic intalox saddle ring. It is a popular random packing in…

Application of ZSM-5 Zeolite Introduction of ZSM-5 Zeolite ZSM-5, Zeolite Socony Mobil #5, is a catalyst first made by Argauer and Landolt in 1969 and patented by Mobil Oil Company in 1975. It is an aluminosilicate zeolite that belongs to the pentasil family of zeolites. Its chemical formula is NanAlnSi96–nO192·16H2O (0 ZSM-5 is an important , so ZSM-5 exhibits high catalytic performance and is widely applied to important processes across a broad range of industries. In the petroleum refining industry, ZSM-5 is used for isomerization, alkylation, and aromatization of hydrocarbons due to its high thermal and hydrothermal stability among solid…

Introduction of Vane Type Demister What is Vane Type Demister? The vane type demister also called herringbone mist eliminator. Consists of a number of serrated herringbone blades with a certain spacing. The blade profile can be smooth or with hooking. Smooth blades are often used for non-scaling service, while hooked blades can provide greater removal efficiency and capacity.In the same environment where small solid particles are present, blade mist eliminator pads are a better choice for liquid and gas separators than wire mesh mist eliminator pads. In terms of operating principle, vane type demister differ from wire mesh type demister.…

Why ZSM-5 Is An Important Zeolite? What is ZSM-5? (ZSM-5) ZSM-5–Zeolite Socony Mobil–5, is a synthetic zeolite. It contains silicon dioxide (Si) and alumina (Al), with the proportion of silicon dioxide being more important than that of alumina. ZSM-5’s chemical formula is NanAlnSi96–nO192·16H2O (0 ZSM-5 zeolite structure  is composed of several pentasil units linked together by oxygen bridges to form pentasil chains. Like the pentasil units, each 10-ring hole has Al or Si as vertices with an O assumed to be bonded between each vertex. Each corrugated sheet is connected by oxygen bridges to form a structure with “straight 10-ring…
