Gas mixture or gas mix

Making gas mixture or gas mixing is a science. There are always new challenges in this science. Having the right equipment solves many problems. The role of each component in the gas mixture system should be clear in order to improve the production process. At the beginning of the production process, there are challenges that we intend to mention in this article and we will provide suggestions for adjusting the gas mixture. Various methods are used to produce gas mixtures, including weight, relative pressure and volume methods. Weight method is the most common method and the most accurate method for producing gas mixtures. In the relative pressure method, Dalton’s law is used to calculate the amount in the gas mixture and in the weight method according to the molecular weight of gases. There are limitations in the production of gas mixtures, which will be different according to the type and characteristics of the gases used in the gas mixture. Among the challenges in gas mixture production, we can mention the reaction of gases with each other, the instability of some gases, and the safety of gas mixture production. The gas mixture is made for specific processes based on a specific method with a specific pressure and temperature.

Applications of mixed gases

Gas mixtures are used in most industries. Gas mixtures have many uses in the medical industry like in other industries. For example, carbogen, which is a mixture of carbon dioxide and oxygen gas , gas used to test lung function, gases of aerobic and anaerobic devices for cell and tissue culture, as well as blood analyzer devices and others. Cases where gases play an effective role in their operation. The gas mixture is also specially used in the food industry to optimize the shelf life of food. Laser gas is among the gas mixtures that are widely used. Industrial laser gas and excimer medical laser gas use a gas mixture. In the following, we will mention separately about gas mixtures.

For example, carbogen, which is a mixture of carbon dioxide gas and oxygen gas, gas used to test lung function, gases of aerobic and anaerobic devices for cell and tissue culture, as well as blood analyzer devices and Other cases where gases play an effective role in their operation.

Consumption of mixed gas in food packaging industries

Mixed gases for food and packaging industries

Using pure gas and mixtures of inert gases in food packaging is the most ideal way to increase the shelf life without changing the physical and chemical properties of food. This is a natural method that has gained considerable popularity all over the world. With our extensive technical knowledge, we offer a wide range of these gases at your disposal, which will naturally increase the useful life of the products.

Laser gas mixtures

In general, laser devices are divided into two industrial and medical sectors. Industrial lasers can be referred to laser or carbon dioxide and laser with RF or rufin, each of which uses a gas mixture with different concentrations depending on the conditions used. Halogen compounds are also used in medical lasers.

Gas mixture supply

to procure High purity gas is usually cheaper than mixed gas. At the same time, having pure gas helps to mix the exact concentration of gases in the process and create the desired result. In addition, when the gas mixture is purchased, it is placed in a container that cannot be easily thrown away or returned to the manufacturer. In addition, the gas inside these chambers is stratified for a long time if it is not used, and the gases with lower density are placed higher than the others. Using a pure gas means you don’t need to stir or agitate the chamber in the lab before using the gas.

By controlling the flow of each gas in the gas mixing process, it is prepared quickly and accurately. The gas mixture preparation method can be programmed with Composer software.

Gas mixture control

In a dynamic system, the percentage of each gas in the mixture is not constant and may vary from day to day. Accuracy in the selection of flow controllers becomes important for this reason. Flow controllers are calibrated for gas types that can change during the process. The settings help to reduce the number of flow controllers needed.

After controlling the gas flow, the non-liquefied gases must be properly mixed. For this, it is necessary that the pipes have a right angle to create turbulence in the flow of gas and to mix the gases together homogeneously. In the absence of a right angle, a static mixing pipe can be used. Many mixing systems have an analyzer that provides real-time mixing updates. If the mixing is not done correctly, the analyzer will beep to alert the technician. Analyzers are calibrated for a specific gas. Otherwise, a mass spectrometer can accurately determine the components of a gas mixture. Of course, if it is possible to prepare a mass spectrometer.

Back pressure of gas mixture

In some real-time mixing applications, continuous pressure is important. For example, in welding, the reduction of pressure in the shielding gas leads to welding flux. Because the shielding gas protects the weld from atmospheric gas. Depressurization occurs when the gas mixture system does not operate 100% of the time and there is a large change in shutdown and startup of the system. The feedback system is in the form of a pressure controller, a pressure gauge, or has a pressure control loop on the flow controller, and it increases or decreases the flow rate according to the pressure in each station.

A pressure vessel or control volume can help reduce pressure drop. in such a way that it acts as a gas storage container and provides gas when needed. The issue of flow control is important to ensure maximum and minimum gas flow at the time of need.

Software for gas mixture

With proper gas flow and pressure control in the correct manner that transfers the gas quickly and correctly, a program is needed to control all the components of the system at once. In many cases, an on-site gas mixing software can integrate everything. There are many options in the market that make the job easier. For example, Flow Vision MX software. It can be used for 10 devices and control the mixing process.

In any case, making a gas mixture or gas mix requires the right software.
