Know the Packed Column Design 1. What is meant by packed column? Packed columns are pressure vessels that contain a filling section, which are pipes or hollow tubes packed with fine particles and packing. They are usually cylindrical and made of stainless steel or glass. Generally, it is shorter than capillary columns. Columns have a higher pressure drop because they are packed with material. Packed columns are mainly used for 3 types of separation: distillation, gas absorption, and liquid-liquid extraction. Unlike the plate column where the gas-liquid contact is staged, the gas-liquid contact in the packed column is continuous. In…

A Select Guide to Types of Structured Packing Structured packing means it is neatly stacked in a tower and arranged according to a uniform geometric figure. It is widely used due to its advantages of large specific surface area, small pressure drop, uniform fluid distribution, and high mass transfer and heat transfer efficiency. Metal-structured packing was first developed, followed by plastic structured packing, ceramic-structured packing, and carbon fiber structured packing. Types of Structured Packing 1. According to its structural characteristics can be divided into two categories: corrugated and non-corrugated. The former is divided into the vertical corrugated type and horizontal…

Overview of Raschig Rings What are raschig rings? Rasching ring is one of the first artificial fillers used in the industry. Usually made of ceramic or metal sheet, its height is equal to the diameter, and the common size is 25mm~75mm (there are also as small as 6mm and as large as 150mm). The wall thickness of ceramic is 2.5mm~9.5mm, the metal ring is 0.8mm~1.6mm, and the wall of a ring should be thinned as much as possible under the condition of strength permitting. Rasching ring is not ideal for mass transfer performance, but it is still used by some…

Applications of Molecular Sieve Molecular Sieve For Natural Gas Drying Natural gas is a very popular source of fuel, it is a hydrocarbon gas consisting mainly of methane or CH₄ and a few other hydrocarbons in smaller quantities. Currently, natural gas is one of the most common energy fuels we use. Drying natural gas is an important matter as water or other impurities in natural gas can increase the risk of damage to pipelines through corrosion or hydrate formation. Natural gas containing water vapour and contaminants can be efficiently passed through molecular sieve columns. With the help of the high…

Mist Eliminator For Wet Scrubber What are Mist Eliminators? The mist eliminator is mainly composed of fixed devices such as corrugated blades, plates, clips, etc. During the operation of the absorption tower in wet desulfurization, , it is easy to generate “mist” with a particle size of 10–60 microns ” which not only includes water, but also dissolves sulfuric acid, sulfate, sulfur dioxide, etc. The“mist” will cause contamination and severe corrosion of fans, heat exchangers and flues. Therefore, the purified gas should be demisted before leaving the absorption tower. The mist eliminator is an important part of the desulfurization tower.…

What is Activated Alumina? What is Activated Alumina? Activated alumina is a porous, solid form of alumina, also known as Al₂O₃. It is also the mineral that makes up the precious rubies and sapphires, the impurities of which are the source of the stones’ brilliant color. After activated alumina has been heated to expel existing water, the material’s high surface area and many pores allow water and other molecules to be absorbed by adsorption. The porous spherical form is the most obvious feature of activated alumina, and these spheres are actually “tunnel-like” on a microscopic level, which makes them easy…

How to Make Ceramic Balls? What is Ceramic Ball? Ceramic balls are a widely used material in the petroleum, chemical, fertilizer, natural gas, and environmental protection industries. The porcelain ball is used as a covering support material for the catalyst in the reactor and as a tower packing. It has the characteristics of high temperature and pressure resistance, low water absorption, and stable chemical properties. It is resistant to acids, alkalis, and other organic solvents and can withstand temperature changes in the production process. Its main function is to increase the gas or liquid distribution points and to support and…

What Does Zeolite Do For Soil? What is Zeolite? Zeolite is an aluminosilicate mineral containing a water shelf-like structure, first discovered in 1756. Depending on its composition, zeolite is divided into square zeolite (Na[AlSi2O6]-H2O) and calcium zeolite (Ca[Al2Si3O10]-3H2O). Its water content is related to the external temperature and the pressure of water vapour. When heated, the water can slowly escape but does not destroy its crystalline structure. The crystal structure has many cavities and channels connecting the cavities in which water molecules are located and can be transported by the channels. Zeolites are used as molecular sieves to draw or…
