1 General introduction Carbon molecular sieve (CMS) as a new type of adsorbent has developed rapidly since it was industrialized in the late 1960s. CMS is a special activated carbon, mainly composed of micropores below 1nm and a few large pores. Due to its special microporous structure, it can be adsorbed according to the size and shape of the molecule, thus having the ability to adsorb molecules. Since EmmettL discovered in 1948 that the carbonization of Saran resin (a polymer of ethylene vinylidene and vinylidene chloride) has a sieve effect, a lot of work has been carried out in various countries. In recent years, research in this area has also been carried out in Western Europe, Japan and China. CMS is mainly used in the field of adsorption separation, it has been maturely applied to pressure swing adsorption separation of N2 and O2 in the air. At present, the major companies producing CMS in the world are mainly Kuraray, Takeda, and some Chinese companies, among them, Gamma Gas CMS are widely used on our own nitrogen generators, also export for overseas nitrogen generator manufacturing and equipment updating. 2 Production process Main production of CMS is as below: Coconut shell primary carbonization → ball milling → kneading and kneading → extruded strip molding → broken strip granulation → secondary carbonization → activation → aperture adjustment → detection → finished product Primary carbonization: refers to the method of carbonizing raw materials under suitable pyrolysis conditions under inert atmosphere. Under pyrolysis conditions, various groups, bridge bonds, free radicals and aromatic rings in the raw material molecules have complexly decomposed and polycondensed reaction, which leads to the formation of carbon pores, expansion and shrinkage of pore size. It is suitable for resins with high volatile substances in fruit shells, such as apricot kernel shell, coconut shell, peach kernel shell, etc. Kneading and extruding strips: After the primary carbonized material is grinded to the required particle size by ball mill, polyethylene glycol is used as an auxiliary agent, phenol resin is a binder, and water is mixed in a kneading machine evenly according to a certain ratio, and the strip is extruded on the pellet making machine. The purpose of kneading is to make the primary carbonized material have a certain viscosity, which is helpful for forming during the extrusion process. Broken bar granulation: The extruded molding material is dried and sent to the broken bar device to break the bar to the desired particle size. The purpose of the broken bar is to make the length of the particles uniform, so that the particles are activated in the same way, and the product obtained by post carbon deposition has consistent performance. Secondary carbonization: The secondary carbonization process is to place the dried coconut shell extruded molding material in the atmosphere and prepare the carbonized product under appropriate pyrolysis conditions. During the pyrolysis process, each group, bridge bond, free radical and aromatic rings and other complex decomposition and polymerization reactions occur, and geothermally unstable components are released in the form of volatiles. The purpose is to develop the pores of carbonized products, expand or shrink the pore size. Conditions that affect the performance of secondary carbonized products include carbonization constant temperature time, carbonization final temperature and carbonization heating rate. Activation: refers to the method of slowly heating treatment under active media conditions on the basis of carbonized land to further increase the surface area, and develop its pore structure. The purpose of activation is to make the active agent react with part of the carbon in the carbonaceous material and the carbon generated by the volatility decomposition of the carbonization process, so that the closed pores and blocked pores can be opened, so that the prepared activated carbon not only has a higher adsorption capacity, but also has higher micropore volume number. Pore size adjustment: using carbon deposition method, on the basis of gas activation, using hydrocarbons or polymer compounds as pore plugging agent to crack it at high temperature, after gas activation, carbon deposits in the pores of porous materials to plug holes, adjust Pore. Pore diameter adjustment: Using carbon deposition method, on the basis of gas activation, hydrocarbons or polymer compounds are used as pore plugging agents to crack them at high temperature. After gas activation, carbon deposits in the pores of the porous material to block pores and adjust hole. 3 Key technologies for carbon molecular sieve production line The indexes of carbon molecular sieve mainly include strength and nitrogen production rate. Strength index, which has two main factors: a) the particle size of the raw material crushed, b) the extrusion strength of the molding process. It must be ensured that the particle size can be stabilized at 20 microns-this requires precise control of the raw material crushing process, and the requirements for extrusion strength are also very strict, as stable as possible at 8MPa. Nitrogen production rate, which is the key index of carbon molecular sieve. It is quite complicated to control, and the carbonization temperature, temperature rise rate, deposition time, activation time and other parameters must be accurately controlled. The first problem that must be solved is the thermal insulation of the equipment. If this is not well controlled, it is difficult to provide a stable processing temperature. Maintaining temperature is just the first step. The key technology is the coherent and continuous combination of each process. Because the temperature control of carbonization, deposition and activation is different, it is necessary to considering the temperature conversion of its automatic transition process, and it is necessary to set up a processing transition space between different programs and realize the conversion of different temperatures in the transition space to ensure the smooth completion of each process. In addition, solving the stability of carbon molecular sieve processing is also a difficult problem in the production of carbon molecular sieve. This needs to focus on the transport stability, deposition concentration stability, activation condition stability, treatment time stability, stability of the molecular sieve and the pore-filling agent or activator, etc., only in every step when it is stable and reliable can the stability of the quality of the carbon powder sieve be finally guaranteed. To achieve these, the following key technologies must be solved: the raw material extrusion molding speed is uniform and continuous, and the particle size is uniform; after the molding, the pellet material is transported uniformly and stable; the carbonization, deposition, and activation stations require uniform mixing of the particles and need to be controlled. The vibration frequency need be controlled well, which enables the raw materials to evenly contact the pore-filling agent or activator during the treatment process, so as to achieve the purpose of uniform treatment and stable index. This process also needs to fully deal with the reasonable relationship between longitudinal vibration and lateral transmission, so that the raw materials can ensure both stability and continuity during the processing. The above-mentioned key technologies are interrelated and mutually restrictive. Only when every step is handled well can the final desired performance be achieved. The controlling process of carbon molecular sieve is a comprehensive multi-disciplinary knowledge and extremely complex process. Every step must be carefully designed, and the connection of each step needs to be meticulous. Only in this way can the produced carbon molecular sieve have stable and reliable performance. This is also why many manufacturers even after many years production, the performance of their CMS is still not stable.

These two sets of 99.995% purity, 600 Nm3/hr flow rate onsite nitrogen generators are used for a pharmaceutical company, which greatly reduces their nitrogen gas consumption cost.

As we all know, the hot galvanizing of strip steel is because zinc can form a corrosion-resistant film on the metal surface in a corrosive environment (corrosive media such as H2O, O2, and CO2), thereby extending the service life of the material. Galvanizing has become an effective method for anticorrosion of steel materials. Hot-dip galvanized strip has a beautiful and shiny appearance, so it is very popular and widely used. Over 160 years, hot-dip galvanizing technology has made great progress. In the long development process of hot-dip galvanizing, the early production efficiency was very low. Until 1931, the Polish Sengimir integrated the annealing process and the hot-dip galvanizing process into one, this world-renowned Sengemir method has truly opened a new era of continuous hot-dip galvanizing of steel strip. Protective gas for hot-dip galvanizing Generally, the input of a small amount of hydrogen in high-purity nitrogen will improve the protective effect of the gas. When the leakage rate of the furnace is not too large, the oxygen infiltrating into the furnace reacts with hydrogen, and an appropriate hydrogen-water ratio can prevent the oxidation reaction from occurring. During the heat treatment, hydrogen and oxygen can react at any temperature to form water. Under this condition, since oxygen is depleted and there are no hydrocarbons in the furnace, only water is the only oxidant. The hydrogen-water ratio is the most important factor in determining the oxidation or reduction potential of the gas in the furnace. In the heating zone of the annealing furnace, adding a small amount of hydrogen is easy to maintain the reducibility of the furnace atmosphere, but it is more difficult in the cooling zone. If the protective gas of the annealing furnace is N2 and H2, and the moisture content is less than 2% (dew point-18℃), bright annealing of steel can be achieved; in the cooling zone, the moisture content should be reduced to 0.03 (dew point-32℃) or less. For strict processes, when the infiltration of oxygen cannot be controlled, in order to ensure the quality of the product, the hydrogen content in the cooling zone should be increased. Since the nitrogen-hydrogen mixture contains no carbides, decarburization occurs. The decarbonization potential depends on the hydrogen-water ratio (partial pressure ratio) of the furnace atmosphere: If the ratio of hydrogen to water is high and the amount of ammonia is small, the reaction is very small. The actual carbon burnout depends on the following parameters: gas flow, surface area of the workpiece, temperature and time of heat treatment. For a hydrogen-nitrogen protective atmosphere furnace with a dew point of 42℃ , processing (carbon content 0.8) Φ2mm steel wire, the furnace productivity is 500kg / h, even if all the moisture in the furnace atmosphere participates in the reaction, the gas flow rate is 100m3 / At h, the total decarburization layer of the workpiece per hour is only 0.082um thick Protective gas plays an important role in the continuous hot-dip galvanizing process of steel strip. H2 can reduce the oxide film on the surface of the strip to active sponge iron, thereby enhancing the binding force between the strip and the coating; N2 is a neutral gas, which can protect the strip from being oxidized in the annealing furnace. Nitrogen also has the safety function of protecting the annealing furnace. The protective gas system is an important part of the hot-dip galvanizing production line, and its investment cost usually accounts for about 10% of the total investment of the entire production line equipment. The reliability of the protective gas system is related to the normal operation of the hot-dip galvanizing production line, and the quality of the protective gas directly affects the quality of the hot-dip galvanized strip. Hot-dip galvanized protective gas system The protective gas system is mainly composed of an ammonia decomposition device, a pressure swing adsorption nitrogen production device and a gas distribution system. Ammonia decomposition atmosphere The ammonia decomposition atmosphere is an atmosphere obtained by using liquid ammonia as a raw material and heating and decomposing it under the action of a catalyst in an ammonia decomposition furnace. Ammonia is decomposed to produce a hydrogen-nitrogen mixed gas composed of 75% H2 and 25% N2. After purification, the impurities are O2 <1ppm, residual ammonia <1 ppm, and dew point <60℃. It is similar to pure hydrogen and is a strong reduction Atmospheric atmosphere is also a commonly used protective gas. At 20℃ and 10325Pa, 1kg of liquid ammonia can be gasified to 1.39m3 of gaseous ammonia, and theoretically 2.78m3 of H2 + N2 mixed gas can be obtained after decomposition. The ammonia decomposition atmosphere can not prevent the decarburization of the water vapor present in the furnace gas, so it must be fully dried. Generally, its dew point is below 40 ℃. Ammonia decomposition cannot be complete, and it often contains a small amount of residual ammonia (0.01% to 0.1%) in the atmosphere. When it is passed into the working furnace, it will cause pyrolysis and generate trace atomic nitrogen, which will cause the metal to undergo slight nitriding. This is not good for steel parts, especially stainless steel strips and wires, which will become brittle and become waste. Therefore, the decomposition rate of ammonia should be increased as much as possible, and purification measures should be taken after the ammonia decomposition. The advantage of ammonia decomposition atmosphere is that the preparation process is simple and it is easy to obtain a pure and stable atmosphere. We use a nickel-based catalyst containing more than 14% nickel, with a compressive strength of> 300N / grain, a space velocity of> 1000h-1, and an operating temperature of 800-850 ° C, and residual ammonia <100ppm. If the decomposition temperature is too low, overload production will cause the catalyst activity to decline or fail. The space velocity test of nickel-based catalyst for ammonia decomposition shows that changing the space velocity has little effect on the decomposition effect. The reaction tube is the core of the ammonia decomposition furnace. The purifier uses high-purity nitrogen to purify and regenerate, which improves the purification effect. Two sets of purifiers are set, one works and the other is regenerated. Alternate rotation work and regeneration, automatic operation with PLC programmable controller. PSA nitrogen production Pressure swing adsorption gas separation technology is an important branch of non-cryogenic gas separation technology. PSA uses air as the raw material and carbon molecular sieve as the adsorbent. Using the principle of pressure swing adsorption, the selective adsorption of O2 and N2 by carbon molecular sieve is used to achieve the separation of oxygen and nitrogen to obtain nitrogen. Compared with cryogenic nitrogen production, PSA nitrogen production has significant characteristics. Adsorption is performed at normal temperature without involving adiabatic problems. The process is simple, the device is compact, the operation and maintenance are simple, the startup is fast, and the gas production is fast (15 ~ 30min). The nitrogen purity of the product can be arbitrarily adjusted according to process requirements, and it has obvious advantages for hot-dip galvanizing that requires continuous supply of protective gas. Compressed air is used as the raw material for nitrogen production. Because piston air compressors are noisy and need frequent maintenance, screw air compressors should be used. Carbon molecular sieve is the key of nitrogen generator. The carbon molecular sieve we choose has excellent adsorption performance and the cost is not high. Valves are also the key to nitrogen generators. They require fast switching speeds, good airtightness, and long life. Generally, the valve switching life is required to be more than one million times. In fact, our valves can be used for several years and are very reliable. The structure of the adsorption tower (including the diameter-to-height ratio), air distribution, and the way of packing and compacting the carbon molecular sieve also greatly affect the performance of the nitrogen generator. The compacting of the carbon molecular sieve and the control of the gas flow rate are very important, otherwise frequent pressure changes in the adsorption tower will cause the carbon molecular sieve to move, wear quickly and become powder and useless. The valve switching is automatically controlled by PLC programmable controller, and the working cycle can be adjusted according to the performance and process requirements of the carbon molecular sieve. In order to ensure the long-term continuous production of galvanized lines, the configuration of the nitrogen generators adopts the scheme of two uses and one preparation or one use and one preparation. Nitrogen purification device The protection gas for hot galvanizing requires high purity. A nitrogen purification device is equipped with a pressure swing adsorption nitrogen generator, which is catalyzed by hydrogenation. The method of oxygen and adsorption drying is simple and reliable, and the purification effect is good. It is easy to reduce the impurity oxygen in nitrogen to less than 1 ppm and the dew point to below -60°C. Its purity exceeds the cryogenic air separation. In order to meet the requirements of galvanized wire, the following optimization measures are taken: The nitrogen purification device uses a high-efficiency palladium catalyst, which can purify the nitrogen purity from 99.5% to more than 99.9999%. The nitrogen purification device adopts a hydrogenation catalytic deoxidation method. For the addition of hydrogen, low-pressure ammonia decomposition should be used, and the working pressure of nitrogen purification should be increased by 0.5 to 0.7MPa through hydrogen pressurization. Water vapor has a strong oxidizing property in the high temperature furnace, so the moisture in the protective gas should be fully removed. The nitrogen purification device is equipped with trace oxygen, trace water, and nitrogen-to-hydrogen analyzers to monitor nitrogen purity online. In addition, the valve switching and regeneration temperature control of the entire system can be automatically operated using a PLC programmable controller. Besides hydrogen purification of 99.5% purity nitrogen. Now more and more customers are also using carbon purifier to get 99.9999% purity nitrogen. Its process is similar to hydrogen purification. After the 99.5-99.9% purity nitrogen is produced, one oxygen remover filled with carbon is equipped. With the help of catalyst, oxygen in nitrogen reacts with carbon to generate CO2, in this way, oxygen is removed and 99.9995-99.9999% purity nitrogen is produced.

PSA Nitrogen Generator's Technical Principle PSA nitrogen generator is a machine producing nitrogen by separating nitrogen from air. It adopts the principle of PSA(pressure swing adsorption). Pressure swing adsorption processes rely on the fact that under pressure, gases tend to be attracted to solid surfaces, or "adsorbed". The higher the pressure, the more gas is adsorbed; when the pressure is reduced, the gas is released, or desorbed. PSA processes can be used to separate gases in a mixture because different gases tend to be attracted to different solid surfaces. When air is passed under pressure through a vessel containing an adsorbent(carbon molecular sieve) bed that attracts oxygen more strongly than it attracts nitrogen, part or all of the oxygen will stay in the bed, and the gas coming out of the vessel will be enriched in nitrogen. When the bed reaches the end of its capacity to adsorb oxygen, it can be regenerated by reducing the pressure, thereby releasing the adsorbed oxygen. It is then ready for another cycle of producing nitrogen. In this way, high purity nitrogen is produced.

Why choose Gamma, not other suppliers? High reliability For PSA oxygen generators, the most important factor is equipment operation reliability, especially for overseas market, where maintenance and repair service should be minimum. Keeping the equipment run at the designed purity and flow rate without malfunction is of critical importance. Similar to other suppliers, Gamma Gas manufactures PSA nitrogen/oxygen generators, but unlike other suppliers, Gamma is using the most advantage process and special equipment structure to ensure long time operation stability. Now in China, there are many companies manufacturing PSA N2/O2 generators, but how many of their products are running without purity decrease? without flow rate drop? without problems such as molecular sieve ejection,etc. Gamma Gas strongly recommend customers to contact us for more details. Energy-saving As PSA N2/O2 generator itself consumes very little power, the main power consumption is the air compressor. Compared with other suppliers, for same flow rate and purity, with Gamma's special process and structure, the compressed air needed is about 20% less, therefore smaller air compressor is needed. Considering years non-stop operation, Gamma this energy-saving feature also brings remarkable benefits for our customers. Please send us your detailed or even brief requirements, Gamma will show you the difference between ordinary and excellence.

Nitrogen use in the lab Nitrogen gas has been used in laboratory analysis for decades. In the past, labs were required to have their nitrogen gas supply delivered in cylinders or in bottles from their closest nitrogen plant, which for some labs could be some distance away. These cylinders or bottles would then supply a chromatography instrument, or perhaps a detector in the case of GC, allowing the lab to carry out its analysis. However, for most mass spectrometers, a high volume of nitrogen gas is required meaning cylinders or bottles would be consumed in a matter of days, primarily when using LC-MS. This can lead to the regular interruption of analysis and inconvenience of switching over cylinders for analysis to continue. Furthermore, cylinders and bottles deliver inconsistent purity when they reach the lower end of their capacity as contaminants can enter the empty space in the cylinder and mix with the nitrogen. These impurities can have an impact on the integrity of analysis as they can react with the sample. There is an alternative for nitrogen cylinders, an on-site nitrogen generator. A nitrogen gas generator not only removes the hassle of having to change over cylinders, it provides an uninterrupted supply of gas at a consistent purity. This consistency is generated using one of two technologies, namely, Pressure Swing Adsorption (PSA) and membrane nitrogen generators.
