Hydrogen Purity Factors
On the purity of hydrogen and its influencing factors
Hydrogen is very important in all kinds of chemical industry. Its purity is related to the success or failure of the process and the quality of the product. Let's try it now.
The purity of hydrogen is the degree of purity of hydrogen. High-purity hydrogen, with few impurities, is indispensable in many fields, such as the manufacture of electronic chips and the smelting of special metals. The tiny amount of impurities can also cause damage to the performance of chips and change the texture of metals.
The influencing factors of hydrogen purity are intricate. First, the quality of raw materials is also. If the raw materials are not pure and contain various ends, such as sulfur and phosphorus, it is difficult to achieve high purity even after refining. For example, the wood is not straight, although the craftsman is clever, it is difficult to become a pillar. Therefore, choose high-quality raw materials as the basis for hydrogen purity.
Second, the method of preparation. Different preparation methods, the purity of hydrogen is very different. The method of electrolysis of water can obtain high-purity hydrogen, but the energy consumption is quite huge; the method of reforming fossil fuels, although the cost is slightly lower, but impurities are easy to exist. Each has its advantages and disadvantages, and needs to be selected according to the situation. The preparation process and the control of conditions are also key. Temperature, pressure, and catalyst can all affect the purity of hydrogen. The temperature is not appropriate, the reaction is not complete, and the impurities are difficult to remove; the pressure is not suitable, the gas separation is blocked, and the purity is not reached. Catalysts, if used properly, can promote the speed of the reaction and improve the purity of hydrogen; if used improperly, it will lead to the proliferation of impurities.
Third, the art of refining. The hydrogen produced often contains impurities, and it must be removed by the art of refining. The method of adsorption can remove some impurities; the technique of membrane separation can also purify. However, the art of refining needs to be exquisite in order to obtain high-purity hydrogen. The equipment of refining also needs to be sophisticated. If the equipment leaks and external impurities are mixed in, all previous efforts will be wasted.
Fourth, storage and transportation. The storage and transportation of hydrogen is related to the maintenance of purity. If the reservoir is not dense, hydrogen is easy to leak, and external gases are easy to enter; if the pipeline is not clean, impurities attached to the wall can also contaminate hydrogen. Therefore, it is necessary to choose high-quality reservoirs and clean pipelines, and often maintain them to prevent micro-changes.
Yes, if you want to obtain high-purity hydrogen, you must study the factors affecting the purity of hydrogen in detail. In the links of raw materials, preparation, refining, storage and transportation, you must be careful to make the purity of hydrogen meet the needs, so as to benefit all things.
