Molecular sieve, because of its strong adsorption capacity and high temperature resistance, is widely used in many industrial enterprises in my country. The commonly used molecular sieves produced by Kailai are 3A, 4A, 5A, 13X and other types of molecular sieves. So how to extend the service life of molecular sieve through 2 techniques?
In order to solve the problem of H₂S odor pollution in landfills, We chooce low-cost raw coal gangue and kaolin were selected, made 4A molecular sieve with good adsorption and catalytic effect through hydrothermal method. The experiment mainly studied the effect of different calcination temperature and crystallization time on adsorption desulfurization performance.
3A molecular sieve, because of its strong drying effect, is an indispensable packing for chemical production towers in the industrial field. In particular, it has a good effect on the drying treatment of water and other gases, and can be used as a desiccant for natural gas and methane gas.
What is the difference between 3a, 4a and 5a molecular sieves? Are these 3 types of molecular sieves used for the same purpose? What are the factors related to the working principle? Which industries are more suitable for? Come and find out with JXKELLEY.
As the earliest product used in industrial packed towers, Raschig ring packing is now favored by customers because of its simple shape and low manufacturing process cost. Questions often asked by customers are how many Raschig rings should be placed in 1 cubic meter, how much is a cubic Raschig ring packing, and how many 50mm Raschig rings are there. Now let’s find out with JXKELLEY.
PTFE Pall ring is referred to as PTFE Pall ring. PTFE is known as the "Plastic King", and the Chinese trade names are "Teflon", "Teflon", "Teflon" and so on. It is a polymer compound formed by polymerization of tetrafluoroethylene. It has excellent chemical stability and corrosion resistance. It is one of the corrosion-resistant materials in the world today. In addition to melting and liquid fluorine, it can withstand all other chemicals.
Metal mesh Dixon ring are a form of random packing used in chemical processing, mainly for laboratory distillation applications.
They consist of a stainless steel mesh formed into a ring with a central divider, and are intended to be packed randomly into a packed column.
Dixon rings provide a large surface area and low pressure drop while maintaining a high mass transfer rate, making them useful for distillations and many other applications.
For CPVC Material Packing, it is necessary to get below knowledge tips before your purchasing.
1. The working temperature is 47-90 degrees, and the fluctuation is too large. The temperature must meet the long-term operation under the condition of 90 degrees. This material cannot withstand the temperature of 90 degrees for a long time. According to the customer technology, the working temperature is only partial in very rare cases. 90 degrees, not long-term 90 degrees, because the long-term temperature of CPVC is below 80 degrees.
Maybe you are looking for zeolite Molecular Sieve all over the world very urgent. Due to Covid-19 spread to many countries still. Let us share its typical application:
1) Removal of CO2 and moisture from air (air pre-purification) and other gases.
2) Separation of enriched oxygen from air.
3) Removal of n-chained compositions from aromatics.
4) Removal of R-SH and H2S from hydrocarbon liquid streams(LPG, butane etc.)
5) Catalyst protection, removal of oxygenates from hydrocarbons(olefin streams).
6) Production of bulk oxygen in PSA units.
For years' experience of the tower packing industrial, customers are always concerned about the price and quality of products. It's a good habit to shop around no matter what you buy, As is known to all, the quality determines the price in this respect. It's also suitable for our tower packing products, After all, the profit of industrial workpieces is low, that you can't only care about the price if you want to buy good good. Today, we mainly want to talk about the plastic random packing products, such as the PP PALL RING. Now let me show you a ture "story": Days before, I got the feedback from one of our client which has brought PP Pall Ring from our company, last years. And this year they has choose the other supplier for the cheaper PP Pall Ring...
Now days we "KELLEY CHEMICAL" get some new knowledge from our customer! Here, to share with you: One of our customer has customized a number of high-quality ceramic balls and ceramic sand filter, and apply it to soilless cultivation technology. Ceramic balls and ceramic sand filter are used instead of soil to fix plants and play a greater role in farming techniques. It looks clean, easy to pick up and clean up. By understanding, the ceramic ball can be recycled, after harvesting a batch of vegetables, they can be reused after disinfection. In tis way, it can achieve both hygienic and environmentally friendly energy saving...
Ceramic glazed raschig ring is made based on ceramic raschig ring through the surface of the glaze to increase its surface corrosion resistance. Ceramic glaze raschig ring is tower packing in the history of the earliest, has fixed the geometry of the annular packing, simple shape, height and diameter are equal, excellent acid and heat resistant performance, except HF various inorganic acid, organic acid and organic solvent corrosion, and can be used in all kinds of high temperature, are widely used in chemical, metallurgical, gas, environmental protection and other industries of the drying tower, absorption...
The stowage of random packing is generally not affected by the ellipticity of tower. In order to facilitate random packing into the tower, can be placed in heaps. Regular random packing tower recommended error can check the corresponding standard. Design according to the standard, the packing manufacturing and parameters are also provided by the manufacturer, and sometimes the optional random packing needs to be processed before use. Need to Notice: Metal packing, the surface of which has a thin layer of oil, which may caused by the lubricating oil when manufacturing, or antirust oil to avoid carbon steel packing being...
Ceramic corrugated packing has a good wet performance of its surface structure, can make the fluid flow faster, to minimize the amount of fluid in the packing. Thereby reducing the chance of overheating, aggregation and coking. Although the ceramic corrugated packing has kinds of advantages, but as the ceramic itself is easy to crush after severe impact, and small porosity easy to plug. In the installation, we must pay attention each layer of packing force evenly, ceramic dregs must be clean. The ceramic corrugated packing is divided into several pieces of different shapes and then assembled into the tower...
The tower packing is widely used in the process of rectificating, distillation, gas extraction, absorption and desorption. No matter how the forms and process be changed, the essence of improving mass transfer efficiency is to maximize the successive contact area in a certain tower space, provide more opportunities for the contact of air and liquid, and reduce the pressure drop as much as possible. The origin and development of random packing is very revealing. Heap of the original packing is in fact wood of gravel, after a long time, until 1907, raschig type steel pipe is simple to cut, according to the principle of high ratio equal to form the famous raschig ring random packing...
Tower Packing refers to the materials filled into the other objects, it is widely used in chemical industry production process. KELLEY wants to introduce the types of various common packing and introduces how to choose the correct packing at the same time with the corresponding pictures, let's be clear at a glance. Tower Packing refers to the materials filled into the other objects, it is widely used in chemical industry production process. In chemical engineering, tower packing refers to in the inert solid materials inside the packed tower, pall ring and raschig ring, for example, its function is to add air - liquid interface, make its strong mixed each other...
Plastic random packing tower is composed of polyethylene (PE), polypropylene (PP), reinforced polypropylene (RPP), polyvinyl chloride (PVC), chlorinated polyvinyl chloride (CPVC), polyethylene (PVDF), made of polytetrafluoroethylene (PTFE) such as tower packing. With high void fraction, low pressure drop, low mass transfer unit height, high point, gas-liquid contact fully, the proportion of small, high heat and mass transfer efficiency, etc. The operating temperature of the plastic random packings in 60-280 degrees Celsius, temperature can be used.
