How Nitrogen Gas Benefits the Food Packaging Industry?

In the following, we will help explain how on-site nitrogen can benefit the food packaging industry in maintaining freshness, food quality and integrity through this article. 1. The properties of nitrogen: Nitrogen is unique and its physical properties make it best suited for food processing. Nitrogen is inherently inert and does not react with food ingredients, maintaining aroma and flavor. It excels at effectively replacing other gases that cause oxidation or support microbial growth. 2. Approved for use in food packaging: Nitrogen is approved and used under good manufacturing practices. Nitrogen is considered a "Generally Recognized as Safe" GRAS gas. This means nitrogen flushing used in food packaging is safe for you. 3. Product shelf life increases: Bacteria need oxygen to thrive. Blowing food packaging with nitrogen removes oxygen, so mold, mildew or harmful bacteria cannot spoil the product once it leaves your facility. 4. Maintain food quality: Moisture can destroy food. Nitrogen is dry and it takes up the entire empty space inside the food packaging. This ensures t

Air Separation Plants Overview

Nitrogen, oxygen and argon have many applications in industry. Like, gaseous nitrogen (GAN) is used as raw material or inert gas, while liquid nitrogen (LIN) is used for refrigeration. Oxygen has a variety of uses in steelmaking and other metal refining and manufacturing processes, in chemicals, pharmaceuticals, petroleum processing, glass and ceramic manufacturing, and pulp and paper. It is also used for environmental protection in municipal and industrial wastewater treatment plants and facilities. Like nitrogen, the inert gas argon is used because of its low reactivity, which provides greater inertness than nitrogen as well as lower thermal conductivity and improved solubility in water and oil. Additionally, argon is more common and more cost-effective than the noble gases helium, neon, krypton and xenon. Nitrogen, oxygen and argon are almost completely separated and recovered from the atmosphere. A cryogenic air separation unit (ASU) is a process unit in which air is separated into its component gases by cryogenic distillation.The plant includes a range of equipment such as distillation columns, heat exchangers, adsorbers and ancillary machinery for compressing, expanding and controlling gases and liquids. Component gases are sold and distributed to customers upon request for a variety of industrial, medical and other professional applications. Air separation plants are constructed differently depending on the product produced and the customer's capacity and purity requirements. I

PSA Pressure Swing Adsorption Oxygen Generator System Process

1. Compressed air purification components The compressed air provided by the air compressor is first passed into the compressed air purification component. The compressed air first removes most of the oil, water and dust through the pipeline filter, and then further removes water through the freeze dryer, and the fine filter removes oil and dust. And it is deeply purified by the ultra-fine filter that follows. 2. Air storage tank The function of the air storage tank is to reduce the airflow pulsation and play a buffering role. Reduce system pressure fluctuations, allowing compressed air to smoothly pass through the compressed air purification components. At the same time, when the adsorption tower is switched, it also provides a large amount of compressed air for the PSA oxygen and nitrogen separation device to rapidly increase the pressure in a short time, so that the pressure in the adsorption tower rises quickly, ensuring the reliable and stable operation of the equipment. 3. Oxygen and nitrogen separation device There are two adsorption towers, A and B, in the 0.3Mpa industrial oxygen generator equipped with special molecular sieves. When the clean compressed air enters the inlet end of the A tower and flows to the outlet end through the molecular sieve, N2 is adsorbed by it, and the product oxygen flows out from the outlet end of the adsorption tower. After a period of time, the molecular sieve in Tower A is saturated with adsorption. At this time, tower A automatically stops adsorption, and compressed air flows into tower B to absorb nitrogen and produce oxygen, and regenerate the molecular sieve of tower A. 4. Oxygen buffer tank

Nitrogen Produce Comparison Of Process Performance

Performance comparison of cryogenic separation nitrogen production, PSA nitrogen generator and membrane separation nitrogen production (1) The process flow of PSA pressure swing adsorption and membrane separation nitrogen production is simple, the number of equipment is small, the operation is simple, and it can be shut down at any time and can be shut down for a long time. Cryogenic nitrogen production not only has a complicated process flow and a large number of equipment, but also needs to be operated in a cryogenic and low temperature state. Before the equipment is put into normal operation, there is a pre-cooling start-up process, and the start-up time is generally not less than 12h from the start of the expander to the time when the nitrogen purity reaches the required level. Before the equipment enters the overhaul, there must be a period of heating and thawing time, generally 24h. Therefore, cryogenic separation nitrogen production is not suitable for occasions with frequent start and stop. Compared with PSA pressure swing adsorption, membrane separation nitrogen production not only has simpler equipment structure, but also has no switching valve, which makes operation and maintenance easier and the time required for gas production is shorter. (2) Cryogenic separation of nitrogen production can simultaneously obtain gas nitrogen and liquid nitrogen, which is suitable for the technological process that requires liquid nitrogen. Liquid nitrogen can also be stored in a liquid nitrogen storage tank as a backup. When there is a short-term sudden increase in nitrogen demand or a minor repair of nitrogen production equipment, the liquid nitrogen in the storage tank can be vaporized and sent to the nitrogen pipe network to meet the

What are the Methods for Industrial Oxygen Production?

1. Air freezing and separation The separated air of the oxygen generator is mainly composed of two adsorption towers filled with molecular sieves. At room temperature, compressed air enters the adsorption tower after being filtered, dehydrated, and dried, and the nitrogen in the air is adsorbed by the molecular sieve. Although this method requires large-scale complete sets of equipment and strict safe operation technology, the output is high, tens of thousands of cubic meters of oxygen can be produced per hour, and the raw material consumed is only air, which does not need to be purchased, transported or stored in a warehouse. Therefore, since the first low-temperature air separation oxygen generator was developed in 1903, this oxygen generation method has been widely used. 2. Molecular sieve oxygen production method Taking advantage of the fact that nitrogen molecules are larger than oxygen molecules, a special molecular sieve is used to separate oxygen from the air. First, the compressor forces the dry air to enter the vacuum adsorber through the molecular sieve, the nitrogen molecules in the air are adsorbed by the molecular sieve, and the oxygen enters the adsorber. When the oxygen in the adsorber reaches a certain amount (the pressure reaches a certain level), the oxygen outlet valve can be opened to release the oxygen. After a period of time, the nitrogen absorbed by the molecular sieve gradually increases, the adsorption capacity decreases, and the purity of the oxygen produced decreases. It is necessary to use a vacuum pump to extract the nitrogen adsorbed on the molecular sieve, and then repeat the above process. This oxygen production method is also called adsorption method. Developed a small household adsorption oxygen generator. Oxygen is enriched in the gas phase, flows out from the outlet, and is stored in an oxygen buffer tank. The molecular sieve adsorbed in another tower is rapidly decompressed

Operation Method Of Oxygen Generator

An oxygen generator is a type of machine that produces oxygen. Its principle is to use air separation technology. First, the air is compressed with high density and then the difference in the condensation point of each component in the air is used to separate it from gas and liquid at a certain temperature, and then it is separated into oxygen and nitrogen by rectification. Under normal circumstances, because it is mostly used to produce oxygen, people are used to calling it an oxygen concentrator. Because oxygen and nitrogen are widely used, oxygen generators are also widely used in the national economy. Especially used in metallurgy, chemical, petroleum, national defense and other industries. Operation method 1. Install the main engine in rotation on the floor or hang it on the wall with a pylon, and install a gas filter; 2. Nail the oxygen supply gusset on the wall or support as required, and then hang the oxygen supply; 3. Connect the oxygen supply port with the oxygen supply tube, and connect the 12V power line of the oxygen supply to the 12V power line of the host.

Principle Of Psa Oxygen Generator

The oxygen generator is a device that uses air as raw material to produce oxygen. The oxygen concentration can reach 95%, which can replace bottled oxygen. The principle of the industrial oxygen generator is to use air separation technology. Firstly, the air is compressed with high density and then the difference in the condensation point of each component in the air is used to separate the gas and liquid at a certain temperature, and then it is obtained by further rectification. Industrial oxygen is generally obtained through this physical method. Large-scale air separation equipment is generally designed to allow oxygen, nitrogen and other gases to fully replace the temperature during the process of climbing and descending to be rectified. Principle of PSA oxygen generator There is 21% oxygen in the air. The principle of PSA separation and production of oxygen is to physically extract oxygen from the air to form a high concentration of oxygen. The separation of oxygen by PSA is a physical method, so the oxygen produced will not be mixed with other harmful substances. The quality of oxygen depends on the quality of air and is better than that of air. The main parameters of the oxygen generator are: power consumption and oxygen production. The oxygen production is usually reflected by the output oxygen flow and concentration. In addition, the important parameters of the oxygen generator include: the pressure of the oxygen generator and the pressure of the oxygen output port. The core of the oxygen generator is a molecular sieve air separation oxygen generator with patented technology. An oxygen generator of different sizes is equipped with a corresponding air compressor to form an oxygen generator unit.

Necessary Knowledge of Central Oxygen Supply System

With the development of science and technology, the scope of application of central oxygen supply has become more and more extensive. In fact, most hospitals have chosen a central oxygen supply system. In addition, a medical oxygen supply system composed of a centralized oxygen supply system, a central oxygen supply system and a compressed air system has become a necessary item in the hospital. Let's learn about some related content about the central oxygen supply system. As labor costs continue to rise, people's requirements for product accuracy are becoming more and more stringent, and companies' requirements for power are getting higher and higher, and central oxygen supply systems are beginning to become more and more important. 1. How does the central oxygen supply system ensure air circulation? The problem of air circulation in the central oxygen supply system is what we need to understand, which is also the key to normal oxygen supply. The process of the oxygen supply system in the medical center is basically the same, most of which can be applied to the central oxygen supply system, which can also effectively reduce the technical difficulty and cost control of the construction process. The air circulation of the central oxygen supply system is very important. Surgery for patients with epidemics: a central oxygen supply system should be established. Method: Use effective means such as adding exhaust fans to adjust the exhaust volume, so that the hospital's oxygen supply equipment changes from positive pressure to negative pressure.

How to Clean Up the Oxygen Supply Equipment in the Maintenance Center?

In recent years, the domestic economic level has continued to grow rapidly, the national level has continued to improve, and the medical and health services have also developed rapidly. Hospital expansion and new projects have blossomed, and high-standard modern medical equipment has also been improved. The central oxygen supply system can maintain cleanliness and hygiene, so how to clean and maintain the central oxygen supply equipment? Routine cleaning and dust removal of sanitary surfaces every day, using wet cleaning, detergent can be used if necessary. Every day, unless there is obvious blood and body fluid contamination, there is no need for routine disinfection of sanitary surfaces. However, after the patient is discharged from the hospital, whether he has an infectious disease or not, he should be disinfected. According to the classification of sanitary surfaces, the cleaning frequency can be adjusted according to the degree of contact. For example, high-frequency contact with sanitary surfaces requires cleaning once every 2-4 hours. The pool for cleaning mops and rags cannot be shared. When it is necessary to clean the mop with buckets of water, the index of bucket replacement of clean water is not based on the turbidity of the water, but based on the items to be cleaned. Wipes and mops in different areas should be specially used in the area and can be marked with colors; after use, the cleaning agent should be cleaned, disinfected, hung and dried for later use. The maintenance of central oxygen supply equipment is generally carried out by the system manufacturer. Common maintenance problems include plugging and unplugging failures of the gas source terminal, valve leakage, gas source terminal leakage, pipeline leakage, compressor failure, oxygen generator failure, etc. Therefore, it is nec

Working Principle of Nitrogen Making Machine

Gas Production Equipment The use of physical methods to separate the oxygen in the air and get nitrogen device is called nitrogen machine, nitrogen machine is mainly divided into three kinds, respectively, are cryogenic air separation plant, molecular sieve air separation (PSA) and membrane air separation method. Nitrogen and hydrogen with a certain flow rate and purity enter the equipment together. After fully mixing in the mixer, it enters the equipment equipped with palladium catalyst deaerator, and the chemical reaction of 2H2+O2=2H2O takes place under the effect of deoxygenation catalyst to reach the purpose of deoxygenation. After deoxygenation, the water gas in nitrogen is dehydrated by the cooler, and then nitrogen continues to enter the monotone to make the nitrogen dew point reach about -60℃. The monotone is equipped with two monotones, in which one monotone absorbs monotone, and the other one regenerates the monotone that has absorbed full water gas, so as to prepare for the next cycle of adsorption operation. After monotonic nitrogen through the filter dust, the final result is high purity nitrogen. Gas seizure device performance indicators, product quality are uneven.

The Difference Between a Ventilator and an Oxygen Generator

A ventilator is not the same thing as an oxygen generator. A ventilator acts like an air compressor, providing air flow like an electric fan, and is used to aid and replace human breathing. The oxygen generator acts like a sieve, sifting oxygen out of the air. Hospitals also use the two machines together to treat serious illnesses such as lung disease and heart failure. The difference between the household ventilator and the oxygen generator is that the principle of use is different. During spontaneous ventilation, the inspiratory action produces negative pressure in the chest cavity, while passive expansion of the lung produces negative pressure in the alveoli and airway, thus forming the pressure difference between the airway opening and the alveoli to complete inspiratory. After inhalation, the elasticity of chest and lung retract, producing opposite pressure difference to complete exhalation. Normal breathing is due to the body through breathing action to produce active negative pressure difference between alveoli and airway mouth to complete inhalation, after inhalation of thoracic and lung elastic.

Nitrogen Generator Makes Nitrogengas to keep it fresh

Nitrogen is a basic environmental substance. It is a colorless, odorless and chemically inert gas, accounting for 79% of the earth's atmosphere. Gaseous nitrogen does not leave any chemical residues when used in the preservation process. It is a common understanding for the manufacturers of beer, wine and fruit juice to use nitrogen to keep fresh. It can make such products more authentic, longer shelf life, and more suitable for the taste of modern consumers. Many beer, wine and juice makers still use carbon dioxide as a fresh-preserving gas. Generally speaking, a brewery with an average annual output of 100,000 tons needs to be equipped with carbon dioxide recovery equipment of 1000 kg/hour, with an investment of about 6 million yuan. But beer production has off-peak season, off-season fermentation is reduced, carbon dioxide production sharply reduced, a lot of carbon dioxide recovery equipment can not start or can not meet the demand. And the fermentation of carbon dioxide to recycle washing, and then compressed purification, liquefaction, and finally vaporization use, energy consumption, cumbersome operation, complex equipment. After the advent of nitrogen preservation technology, compared with carbon dioxide, nitrogen production mechanism has many advantages. 1, with inexhaustible air as raw material, using pressure swing adsorption method to separate nitrogen from the air, low cost is incomparable to carbon dioxide recovery device;

CNC Lathe Processing Accuracy Should Know What

Precision problem in nc lathe processing Influence of position error in NC lathe processing on machining accuracy: Position error refers to the variation or deviation degree between the actual surface, axis or symmetry plane of the processed parts and their ideal positions, such as verticality, position and symmetry. CNC machine tool processing position error usually refers to the dead zone error, the cause of position error is mainly in the machine tool parts processing due to the transmission of clearance and elastic deformation caused by the processing error, As well as in the processing, the tool head of the machine tool needs to overcome friction and other factors resulting in position error. In the open loop system, the position accuracy is greatly affected, while in the closed loop follow-up system, It mainly depends on the accuracy of displacement detection device and the speed amplification coefficient of the system. Machining accuracy error caused by geometric error in NC lathe processing: CNC lathe processing, due to the tool and fixture in the process of external forces and heat generated by the influence of external factors, the lathe's geometric accuracy is affected, lathe processing parts produce geometric deformation, resulting in geometric error. According to research, CNC lathes produce geometric error of the main reasons are nothing more than the following two: internal factors and external factors. The internal factors of lathe geometric errors refer to the geometric errors caused by the factors of the machine tool itself, such as the levelness of the lathe table surface, the level and straightness of the lathe guide rail, the geometric accuracy of the lathe cutter and fixture, etc. External factors mainly refers to the geometric error generated under the influence of factors such as thermal deformation

The Nitrogen System Requires Regular Maintenance

Nitrogen making machine is carbon molecular sieve as adsorbent, using pressure adsorption, step-down desorption principle from the air adsorption and release of oxygen, so as to separate the automatic equipment of nitrogen. Carbon molecular sieve is a kind of coal as the main raw material, after grinding, oxidation, molding, carbonization and through a special hole processing process and become the surface and interior full of micro hole cylindrical granular adsorbent, is black. The pore size distribution of the carbon molecular sieve allows different gases to diffuse into the pores of the molecular sieve at different rates without repelling any of the gases in the mixture (air). The effect of carbon molecular sieve on the separation of O2 and N2 is based on the small difference in the kinetic diameter of the two gases. The kinetic diameter of O2 molecule is smaller, so the diffusion rate in the micropores of carbon molecular sieve is faster. The kinetic diameter of N2 molecule is large, so the diffusion rate is slow. The diffusion of water and CO2 in compressed air is similar to that of oxygen, while argon diffuses slowly. The final concentration from the adsorption column is a mixture of N2 and Ar. After long-term use, the pore size of carbon molecular sieve will change; If the compressed air contains water and oil, it will also affect the micropore size of carbon molecular sieve, thus affecting the performance of nitrogen production, resulting in the reduction of nitrogen purity. Therefore, the nitrogen system, especially the compressed air pretreatment system (air compressor, cold and dry machine, three-stage h
