PSA Hydrogen Purification

Why We Use Molecular Sieve for PSA Hydrogen Purification? Pressure(high pressure and low pressure) Swing Adsorption (PSA) gas separation and purification technology became a production process and an independent unit operation process in large chemical industries, which was rapidly developed in the 1960s. On the one hand, with the world’s energy shortage, countries and industries are paying more and more attention to the development and utilization of low-grade resources, as well as the increasing demand for environmental pollution control, making adsorption separation technology increasingly important; on the other hand, since the 1960s, adsorbents have also made significant progress, such as…

Molecular Sieve For Medical Oxygen Generator

Types of Medical Oxygen Gas Generators Medical Oxygen Gas Generators are in fact simply divided into two types according to their use: medical oxygen concentrators and home health care oxygen concentrators; for us the use is auxiliary treatment and daily health care. The differences between the two are: In terms of oxygen concentration, medical oxygen concentrators require a stable oxygen concentration of ≥ 90% and an alarm must be issued when it falls below 80%. The oxygen concentrations required for home health care are not high, as long as they are 21% above the oxygen concentration in the air, some…

VPSA Oxygen Generation

VPSA Oxygen Vacuum Pressure Swing Adsorption oxygen equipment, referred to as VPSA oxygen production equipment. The mixed bed is formed by VPSA special molecular sieve(lithium-based molecular sieve) and the desiccant is used to selectively adsorb impurities such as nitrogen, carbon dioxide and water in the air, so that oxygen accumulates and collects at the end of the bed, and the molecular sieve bed with adsorption saturation state is desorbed under the condition of evacuation, so as to circulate the oxygen with high purity (90~95%)。 PSA VS VPSA PSA oxygen production is separated by pressurized adsorption and atmospheric pressure desorption, and…

Lithium Molecular Sieve Used In Oxygen Generators

Lithium molecular sieve for small oxygen concentrators There are two common types of molecular sieve for small oxygen concentrators: Lithium molecular sieve and NaX molecular sieve. The LiX zeolite is more effective than NaX zeolite and therefore it is able to decrease the dimension of oxygen generators and makes the oxygen concentrators smaller and more convenient to take along. However, the cost of a NaX molecular sieve is much less than Lithium molecular sieve that which is very popular in the market as well. Nake chemical is a professional in oxygen generators molecular sieve manufacturing. In our product models, the…

Oil & Gas Process

Petrochemical and oil and gas processing produce exhaust streams filled with potentially hazardous chemical and gaseous residues. Chemical scrubbers, closed thermal halos and thermal oxidizers are used to remove residues from the exhaust. The contaminated system has a full range of scrubbers and oxidants designed to remove specific chemical or residual wastes from each facility process. In this processing, Naike Chemical can offer mist eliminators, random packing, structured packing, bubble cap trays, sieve trays and so on. Natural gas processing is a necessary means to monetize natural gas from production source to liquefaction or pipeline quality. First, we should treat…

The production process of organic fertilizer includes composting of organic waste and deep processing of fermented organic waste. Because the direct use of organic waste can cause harm to the roots and soil of crops and plants. On the other hand, composting can transform organic matter into humus through microbial activity. In this industy, Naike Chemical always offer structured packing, random packing and column internals.

Refining is to purify compounds or mixtures by chemical or physical methods, or to extract what is needed from them. For example oil refining, sugar refining, precious metal refining, API  Refining, etc… In the whole refining process, we always use structured packing, gauze packing, random packing, trays, distributors, mist eliminators and ceramic support balls.

What is Zeolite Powder Used for?

What is Zeolite Powder Used for? 1. What is Zeolite Powder? Molecular sieve-activated powder is a kind of white powder, which is formed after deep processing and activation of synthetic molecular sieve original powder. The original molecular sieve powder loses moisture during the high-temperature roasting process, therefore the activated zeolite powder has a strong adsorption capacity. It can be directly used in production as an adsorbent with selective adsorption. 2. Benefits of Zeolite Powder? The molecular sieve-activated powder is mixed, dispersed, and adsorbed with materials. It is an amorphous desiccant. It can absorb impurities such as moisture that affect the…

What Does the Catalyst Do in Cracking?

What Does the Catalyst Do in Cracking? What Are the Products of Catalytic Cracking? Catalytic cracking is one of the petroleum refining processes, which is the process by which heavy oils are cracked in the presence of heat and catalysts and transformed into cracked gas, gasoline, and diesel, among others. The process of cracking heavy oils under the action of heat and catalysts to transform them into cracked gas, gasoline, diesel, etc. The main reactions are decomposition, isomerization, hydrogen transfer, aromatization, condensation, and coking. Compared to thermal cracking, it has a higher yield of light oil, higher octane value of…

What is the Major Use of Carbon Molecular Sieve CMS?

What is the Major Use of Carbon Molecular Sieve CMS? 1. What is Carbon Molecular Sieve? A carbon molecular sieve is an excellent non-polar carbon material. Nitrogen-producing carbon molecular sieve is used to separate air and enrich nitrogen. It adopts a low-pressure nitrogen- generation process at room temperature, which has lower cost and faster nitrogen production than the traditional cryogenic high-pressure nitrogen generation process. Therefore, it is the preferred pressure swing adsorption (P.S.A) air separation nitrogen-rich adsorbent. This nitrogen is used in the chemical industry, oil and gas industry, electronics industry, food industry, coal industry, pharmaceutical industry, cable industry, and…

Difference between PSA vs TSA

Difference between PSA vs TSA What do TSA and PSA stand for? Molecular sieves are used in a variety of applications, but the goal is always the same: to separate two or more components from each other. This can be achieved in several different ways, but the most common processes are variable pressure adsorption (PSA) and thermal swing adsorption (TSA). Both methods involve using a sieve, regenerating it, and then reusing it by taking advantage of the fact that the sieve adsorbs contaminants more strongly under certain conditions than under others (physical adsorption). How do PSA applications work? PSA is…
